I am nt a engineer i am only a student of 11th class i always think..... . The vehicle which is run from battryy they use large amount of electricity ... ... And battry backup is no more in like scooty...rikshas... Ect... . If we fit a dynamo r a turbine (what ever says i dnt knoww).... Which generate electricity by rotating i mean rounding.....if we fit this type of small machine in back tyre or front tyre of scooty ...and attach with tyre nd when tyre of scooty is moving then dynamo r turbine which creates electricity....is rotating and electricity is producing and which is store in other battry which is also fit in scooty. I mean 2 battery in a scooty when first battery is finish we push a button and scnd battery starts and first battery charged by turbine r dinamo ....and when our scnd battry is finish we start frst battry and scnd battry start charging ............with this technique we hv no tension fr charging scooty by electricity r no tension for full the tank of fuel. . For example dams when water is falling on the turbine then turbine is rotating and creates electricity. Same in generators ot makes electricity by rotating turbine ... . My english is nt gud bt i think u understand iit

Hello friends we are suffering with a power cut every day from atmost 2-3 hr's in city and if we go to the villages we see that there is a power cut from atmost 4-6 hr's daily. so, we have to concentrate on the places where the power cut is severe and we should come forward to solve them. first of all if we solve the problem where the poor live other people who are in great positions with no problems and power cut can get hope on us and they can help and support us by offering us some money to solve thy problems. so,my dear people try to solve the problems of the farmers who are suffering with severe power cut. so,then if we solve the problems of the farmers they can get sufficient power for the farm and they can supply sufficient water to the crop with the help of power facilities in the villages Thank You N L Aditya Patel

I have designed a Solar Collector, which can receive Solar Short Wave Radiation with Conventional Parabolic Solar Trough. The Solar Collector is made of clear silica Glass( 6mm thick). The Cross Section Glass is partly parabolic & its focus point is common with the main parabolic reflector. The axis of the Glass parabola makes 45 degree of angle with the latus rectum & axis of parabolic reflector. Solar radiation enters through the calculated opening of the glass. The Glass Screen is surrounded by the water tubes covered with Platinum black with 0.98 emissivity. The Glass Screen allow only short wave radiation wave length below 2500 nm. Total Solar collector system is covered with heat insulating materials. The shape of the glass is so designed that no reflected & radiated cant escape the system, and thus more than 90% of radiation will be absorbed.

Well for today we just know how engineering helps us to make day to day life better. But the fact being its kind of the only science we have as a trump card to undo the damage done to our surroundings by science. Isn't that a good enough help for our future , to atleast know that the future even exists??

To whom it may concern, My idea deals with a world without hydrocarbon fuels. I want to see an automobile built using a closed cycle hydrogen/oxygen system. First, the fuel tank is filled with salt water. Then, utilizing a yet-to-be found catalyst, the on-board electrical system electrolyzes the solution into hydrogen and oxygen. Each gas is then sent, via compressors forward to the engine compartment, each on its own side of the car. The oxygen, under relatively low pressure, enters the intake manifold and in time enters the combustion chamber. Meanwhile, the hydrogen under high pressure is injected into a precombustion chamber which is connected to the main combustion chamber by an orifice as in a gas (not gasoline) engine. The resultant combustion produces only water vapor and heat. The water vapor is then condensed and returned to the fuel tank to begin the cycle again. Water will be added to the cycle only when losses need to be made up. The catalyst for this process is currently being researched so even sea water can be used. This would also be a boon the world's merchant services where ships could use the sea around them for fuel. There would be no need for carbon sequestering. The world's hydrocarbon resources can then be relegated to producing plastics and various other materials that can be recycled. Island countries would have a limitless supply of energy.

I'm a second language English teacher. I wasn't a science major, let alone an engineering major, so forgive my lack of technical elaboration. One of my youngest (and brightest) students has been brainstorming ways to generate or capture and recycle energy. Today, he proposed capturing the waste heat energy produced by the friction between car tires and the road surface. Does that sound technologically feasible or potentially worthwhile, economically?

I am not an engineer by any means. Just someone with a few ideas. This idea is to generate electricity without using any non-renewable resources with no environmental impact. this simple idea uses the two most abundant renewable resources we have on this planet. Also without either one of them we wouldn't be able to survive anyway. The simple idea I have is just using water(salt or fresh but preferably salt) and pressurize it just using the sun. No coal,no gas,no fossil fuels at all. If we can concentrate the suns energy on the water such as a large magnifying glass or multiple magnifying glasses we could boil the water to steam in a pressure vessel. It then can turn a generator. Like I said before,I'm no engineer but you get the simple gist of it and can take it from here. Thanks

I have a very good idea to save our time. Right now the ongoing generation dont have time to spend with there family. But this problem we can solve this by using this idea. My idea is that to make the Road runing like cars (same like walking pannel we have in malls and airport) This can save a huge amount of fuel and time for our next generation. I hope you can think on this. This will be the latest technology if we have to apply and the first country in the world for this idea... Thanks Jigar

If you fit debris filtered turbines into major sewers can we generate reliable and strong sources of electricity? Similarly on a smaller scale could homes achieve this at a local level (feeding their own power supply) by adding turbines to their own water outlet pipes? The flow of water generates a constant energy fed by gravity we seem not to tap today. This leads to... Gravity is a force and therefore an energy you could harness to overturn the principle that perpetual motion is impossible. Without energy it is impossible, but gravity is an energy source. Can it give sufficient energy to overcome friction? I don't know, but with engineering I think it can. Take the principle of a simple child's swing on which the child can power their own motion simply by shifting their weight forwards on the forwards motion and vice versa backwards. By engineering and use of low friction materials I believe it is possible to start a swing at one side with the seated weight loaded to carry it through to the other side extreme. Then, via engineering the seated weight trips (using a levered switch and gravity) to slide to the opposite side of the seat, putting the weight in the correct position for the return journey and replicating the weight shift pattern of the child. Possibly this release needs some electrical or magnetic energy input but hopefully less than generated. Through engineering and the design of joints / levers / weight distrubution (shifts with gravity) and switches / magnets it should be possible to efficiently replicate the efficient action of a child to create the illusion of perpetual motion using gravity in an efficient machine to perpetually generate energy. The energy is extracted via the axis point and by tapping into the movement of the seat - the same way a steam turbine would work today. Challenge. Make it work!

Proposal Summary Did you know that there are 1.4 billion people without electricity. My Proposal brings the price of the Megawatt to $8 and this is very favorable indicator. 1. The proposal is for a new system that uses naturally found high pressure in the deep oceanic water to produce electricity. 2. The advantage of our technology is that it offers unlimited capacity. The proposal could use existing pipeline technology and it could provide a constant flow of high pressure from deep oceanic waters. The electricity would be transported from the power plant to the consumer using existing cable technology. The Proposal is environmentally friendly; it is efficient and has no waste or pollution. The Unit would be built away from human habitation and it would not affect the marine biology. 3. I am using the pipeline as a closed system with the deep pressure being the source of the energy. I have developed the 'Shielding Technology' and the 'Pressure Differential'. This is a notion where the pressure in the High Pressure Chamber is dispersed into a Low Pressure Chamber through a Medium (currently confidential) that allows High Pressure to be released without a loss of water. The idea is that High Pressure moves fast through the Medium and the water is Captured without being spilled into the Low Pressure Chamber. High pressure will rotate the turbine propellers and will produce electricity. The materials used have to withstand high pressure and salinity of the water in the deep oceans. The Proposal is Patent Pending. 4. The proposal would allow the building of 100 MW Units at 1500m depth. Once the unit is connected to the National Grid, it would supply renewable electricity 24/7. The full scale power plants generating 1000 MW could be installed worldwide.

Have you ever considered pioneering/colonizing underwater? I'm under the impression that the use of unlike materials is dangerous in high pressure situations due to the different expansion rates. Have you considered using one material ie., reinforced plexiglass or plastic in honeycomb plates welded together at the precise angles to create the shell. That shell in the shape of an egg on it's side with an entrance to the water at the bottom. Reinforced inside with carbon-fiber, used to create the walls, floors, and conduit used to transport power,water, or waste. The power would be that of a nucleur submarine because it is already proven until another power source can be used... The living quarters, research/work areas, and community/dining areas would all be either bigger or smaller honeycomb areas within the honeycomb. We have not even begun to explore our own planet under the oceans. Is it possible that we could find archeological proof of civilization (before the time of the biblical flood and the realm of Noah, or maybe the entrance to the famed 'Garden of Eden?') Is it possible to create another way of farming where the ecology under the seas would be beneficial and useful to the agriculture so that we wouldn't want to pollute the oceans but create a colony for underwater agriculture? Is it possible to tap into the earth's crust and use the thermal energy? Why not? If you might be looking for a volunteer to tend a garden and do research for living conditions in a shell underwater; Here I am... See me for further details if interested...

I think preservation of traditional culture integrated with the modern era developments will be the challenge for engineers in the new millennium. If not preserved the civilization's rich creations of the past, our cultural heritages with thousands years' long history may be lost.

Health Informatics: Nerve pulses which control our reactions and our perception of the outside environment are electrical pulses. I had this thought; What if we used sensors to collect this electrical signal pulses as data which we can analyse and use the data to develop a model or basics on how a healthy body would react. Functions such as hearing can be stimulated in isolation from a number of individuals and the data collected an patterns analysed. This, I think would provide a framework on which we can understand body functions and further, if our analysis provides accurate predictions on our perception of the outside world, a step in brain mapping. With advancement and investment in Big Data currently, this seems a more achieveable idea

We are now in the age of computers and the truth is easily exposed using basic mathematics and physics and the power of computers to do the numerical calculations required in the equations that we derived for a particular problem. Microsoft Excel can be applied by the computer to perform any numerical calculations required in the equations derived mentioned above. Approximate methods may not be correct anymore once the exact method is applied. The whole world is still using the approximate method exemplified in technical books and favored by authors and college professors who had been brainwashed and buried using existing literature even though computers are all over the place. I am the only one in the world doing the ‘rotation of axes’ while everyone is copying the ‘principal axes’ in any given rectangular and circular section. I have shown the way in all my presentations and technical books on the analytical method in structural analysis. It is obvious that a new paradigm from the approximate to the exact method is called for everybody to discover the truth about anything using basic mathematics and physics learned in school. A serious researcher should follow the saying ‘seek ye the truth and the truth shall make you free’. Tons of literature based on approximate methods should now be discarded in favor of the discoveries which can be made by this new paradigm. Ramon V.

In crater you must think concentric layers but also a STEM that locks into the bottom and the dome must fill the whole crater and mold to it. Then it is sprayed with a glue to add layers to make it strong including MARS surface as construction material and protection. the end product is a covered dome in a crater with a function to drill down and if lucky find raw materials. using more than one payload it is possible to send machines to build a road connect other payloads to the structure via tubes that are also covered in layers over layers to make a solid structure. With robots and no humans it is possible to then construct on Mars with glue and MARS itself and seal whole rooms and prepare for humans. it is possible to land "dragons" to add instant services for the robots such as REPAIRS and so a repair shop to storm shelter or other function needed on site. Imagine a dragon and a layer over it opens up and a whole giant dome is inflated and begings to solidify.... now you got a dragon in a cave... or egg! Mars is for inflatable units and then making them stronger with layers. Humans come AFTER the seventh dome is in and a couple to start and a couple to move forth. each 7th dome. add tunnels from dome to dome and seal them with layers and presto! Base transport and SECURITY other project do not offer as much! Mars is about concentric wisdom. you shall make concentric DOMES and concentric tunnels and concentric sub surface network. function with concentric permit future changes in functions to be easy with no complications... always it shall be concentric spheres domes circles tubes... and arches Universe has proven how it survives... we just have to apply the same rules. make a mushroom like form on Mars... dome and stem under the surface. Dome the dome FORGET LIGHTING and forget power and forget water and food and all the junk you do not need YET! Let it be prepared then lived in! Always concentric and always PLUG AND USE TECH and always the whole as multifunction device as a function.... so it makes power, insulates, protects, permits machines to work in very familiar surroundings for minimum errors long term. It was and always shall be repeat the concentric... domes tubes circles of tubes wheel and spoke construction that is layered and layered to become strong with Mars itself.

I am an Electrical Engineer and I constantly have to charge my phone whenever I am on the go. My main focus in my work is to harness solar energy for everyday uses that will ultimately make the world more greener and energy efficient. The idea I have is creating an iPhone or other smartphones that have solar panels within the phone itself that will capture heat energy from the sun and convert that into solar energy that keeps the battery charged whenever a person is outside in any capacity or location. Also, inside the phone will be a thermoelectric cooler that will keep the battery from overheating but still maintaining the charging.

I created a solar heater out of aluminum soda cans. This would be an efficient way to get rid of soda cans and have them serve a purpose. It is made by washing out all of the cans, then poking holes in the top and bottom of the cans. I then glued them together in columns. After, I spray painted black so that they would absorb more heat. I put these in a wooden frame, and inserted a fan at the bottom to blow air into it. A sheet of plexiglass went over the top of the wooden frame. The fan would blow air into it, and the cans would heat up by sunlight, and the air would come out heated. I recorded measures from up to 90+ Degrees Fahrenheit coming out of the top. I just need a way to make it smaller with the same efficiency. Any ideas?

Though, I have not checked this to a large degree. But, the much that I have gone through does not include quantum computation. One of the obstacles of realizing a quantum computer is decoherence- this is the phenomena through which quantum systems loose their coherence as a result of unavoidable interaction with it's environment. And it is the coherent superposition of quantum systems that enable them have advantage that they have over classical ones. While the guys at D-Wave systems use a cryogenic system to house the quantum processor, I am suggesting using some kind of mesoscopic system that will mediate interaction between the quantum system and it's classical environment. In my opinion, if this idea is perfected, it can lead to the production of quantum computers on a much larger scale and mobility. But, we have to be able to quantify decoherence to know just how much of it can disrupt coherent superposition of a quantum system.

I'm just a man with many ideas and i literally had to tear the little blockage down so the water could move it never got knocked down.I know it's just creeks but if you built my ideas on a larger scale wouldn't it work on a larger scale.

An idea to expand on the earlier idea that wood chips in ice is inpenatrable and floats. i think it was an idea for making aircraft carriers before we had the available steel and other resources.the idea could be used for good and not military purposes. the problem with making a giant wood chip filled piece of ice was that it would have taken more steel and resources to build freezers large enough to use than it would to just build the boat out of steel. i say bring the whole operation to the arctic and use 2 ships with flat sides that would be used for the sides of the mould for the "wood icecube" and fit them with 2 ends and no bottom since both ice and wood float. fill the sides of the ship and the ends with passages that can rout steam for when you need to get the wood icecube free of the mould. and have the ships powered by a steam engine with a a solid thermite fuled boiler. aluminum and rust are cheap and the by products aluminum oxide and iron could be sold to materials companies. when freeing the ice cube from the 2 ships you would rout enough steam to melt the contacting surface of ice from the sides of the ships and ends where one corner of the mould would releas and a pivot at the oposite corner would alow this massive mould to open freeing an inpenatrable block of material the size of a football field cubed. this block could be stung along on end or stacked or carved out or anything really. how you get the wood chip filled ice in it would be to have very large snow machines blasting the surrounding water into the air with a hopper of wood chips being feed into the path where it would all freeze in the sub zero air and fall into the massive mould. using water for steam power and ice making is logical because you would be floating in an abundance of it and usin a thermite boiler is logical because fossil fuels would cost more and polute. I'm not sure what can be said about the woodchips falling into the sea when the block begins to melt.

EXTREME SOLAR Extreme Solar is a revolutionary idea to increase energy production in a green manner which will help with the decrease in production of greenhouse gasses that cause global warming. Extreme Solar is the cleanest form of energy production in the world and is the most cost efficient; revolutionizing the world in becoming the main form of energy used in these modern times, and is much needed to insure life for the human race. Extreme Solar is taking a solar power system like current ones and adding my patented solar magnification device, which will increase the amount of energy received by the suns rays, also increasing the amount of energy received by the solar cells. Maximizing amount of energy production produced from solar power systems, thus making them as efficient as possible. Extreme Solar will work on Photovoltaic’s (PV) systems which directly converts sunlight into electricity, or indirectly using concentrated solar power (CSP) that uses lenses or mirrors and tracking systems to focus a large area of sunlight into a small beam. all model of solar powered systems such as solar direct systems that only produce energy during the day, Dc systems which produces energy during the day and stores the energy into batteries, Hybrid solar generator systems that are off grid and back-up powered systems that consist of pv array, charge controller, battery bank, inverter, tertiary power source wind turbine, gas generator, and steam, solar grid tied solar, and Concentrated Solar power (CSP). Extreme Solar works on Photovoltaic’s (PV) systems by magnifying light received by the sun and increases amount of energy, and on Concentrated Solar power (CSP) by taking the focused sunlight and magnifying it before it hits liquid filled pipes increasing amount of heat and produces more steam to turn turbine, and also can be placed over liquid filled pipes to take none focused light above pipes and can be focused on pipes adding an additional amount of energy or heat to heat liquid filled pipes increasing energy production all around. Extreme Solar can be used on PV systems and CSP systems, stationary or osculating systems which move with the sun as it raises and sets maximizing energy production, getting the most out of the system.

The thoughts of engineering can be outdated before building even begins. the simple task of research and development could go on infinitly in theory on paper but it is the physicsl test that unvovers flaws in the design, materials, unforseen elements and physical limitations and components. With the information we have today this too can now be done on paper and tests can be carried out in a theoretical windtunnel based on the data collected from previous tests so the whole process of building certain mecahics no longer is required because it either already exists and the data collected could be used. This would free up nations from unnecessary labor, expenses and resources/funding if there was a global pool of...oh wait the internet... the problem now lies in choices, trends and social phases, and financial traffic if money was considered vehicles on roads and shops or expenses the destination. What is attracting the traffic, where is if blocked, flowing, lost?

Thinking first. Switch 99.9% of people from repeating the same old things to the majority thinking. Move a 1000 years in day. Break the link between a calendar and events in them. A year can carry unlimited thoughts. Unlimited developments. Humanity hasn't moved since our evolution. In the same galaxy, same solar system, same planet, same land masses, live in the same square boxes, travel up the same flat crowded roads, make up the same gods, fight the same wars, collect the same plants, eat the same food, have the same sex and die the same death. Nothing changes. We dont even live in two thirds of the planet or five feet either side of the biosphere. We're self satisfied two diemensional flatlands monkees with the added burden of organised superstitions. Electronics has not even increased its rate of improvement for forty years. No improvement in Moore's law, ever. Hopeless. Why hasn't the rate of improvement doubled every eighteen months, now that would have delivered a billion times the computing power by now. 35 hour weeks and research grants are the reason. Weeks have 168hrs. The prime directive is to think more time. To eliminate death Time second. We use this added life time to think. Think how to connect intellect. To instantly communicate. Energy third and Resources forth. The output of thought after time, is then energy. Fusion energy. Nothing else is worth a candle. Forget all the silly voodoo green sources, they are many orders of magnitude too tiny. We need energy to travel stellar distances and to mine and convert vast resources. I tire of small thinking, This planet has 40000 tons of extra resources each year. Nothing over a few tons ever leaves. Everything that ever was here, is here. All we need is energy to convert it. With energy and what we have, we can make everyting we need a billion times over, for ever. And then we can accept our real responsibility and search the universe. We need to stop burning down human libraries and stop death, now. The strange thing is, I sound like the mad person. Not the rest of the planet. Never laugh at the past, its still a flat earth. Nothing changes.

I have read that they have made a solar-powered car, but what i was thinking was to make a magnetic hoverboard. One that would maybe react to metals to keep it floating. I think it would be a good idea, so you can ride smoother without having the cracks in the sidewalk to worry about, and you would have a smaller chance of getting hit by a car if you were able to float above it if you wanted. You would control it like a skateboard, or surfboard if you were riding it on your stomach. For smaller kids, or if you can't balance well, you could have locking, attatchable handles. I hope you liked my idea!

I honestly think, instead of having to go out of our way and creating our own Carbon Dioxide to capture it, burning unnecessary fuels just to get what's already in our o-zone layer. I say we should create a netting, so small to catch Carbon Dioxide particles as they come from normal day life, people driving their car, factories burning their materials for their own benefits. Saves money, and its simple, only until you find a way to make a netting solution that would be harmless to the o-zone, or anything else up there, or even that small to even capture Co2. It also would help our o-zone with all the Co2 being burned and released. Save us a couple more years, save the earth a couple more years.

The tubes are thin walled and will be about 15mm diameter. The frame is about 500mm square The first part of the frame needs to be free to hinge on all sides to go into a flat-pack and so consists of 3 tubes joined together with fixings and the 4th tube/brace needs to be fitted (after assembly into a square) to provide the bracing required and to make the square rigid by either inserting into or alongside the open end of the frame thus making up the completed frame.

I've got an incredible idea for flying cars that are VTOL and electric. What makes my system superior is the efficiency factor, which is at 90%, a vast improvement over traditonal aircraft. All airplane wings and helicopter propellers produce drag to generate lift or thrust, but they waste the majority of energy put into the drag production, whereas my system uses almost all the drag produced for thrust and/or lift. This is a revolutionary idea that is based around simple drag physics that have been proven for centuries, meaning there is no chance of failure. Practical VTOL flying cars can be produced in our lifetime with this technology and this is not too good to be true, it is only physics being applied in an outside-the-box sort of way.

I disclosed how get existing or new non-accelerated vehicles and other machine that save much energy and directly or indirectly emit least emissions in the world: Creator’s idea is non-accelerated, quiet, and green vehicles and other machines are disclosed by two USA patents 8,011,274 at 09/06/2011 and 7,191,676 at 03/20/07 for making money by both manufacture and customer; prevents environment and economic collapses. There above 1,000 state-of-the-arts gearbox apparatuses designs are created by revolutionary methods. What are the main 7 differences in design (other at www.repowermachine.com)? 1. It has least numbers of gears/maybe shafts in the world without competitors in future; 2. It is not brake in the propulsion of machine, uses only one torque or speed of motor shaft and produces all needed speeds including the sufficient number of overdrive speeds that eliminates motor interior gas or magnet field acceleration system and its noise; 3. More simple shifting mechanism design opens opportunity to create three regimes as manual, semi-automatic and automatic simultaneously with operation by computer; 4. It reduces energy consumption, emissions, noise, power and cost of motor in many times; 5. It improves driver’s safety by simplification of operation; 6. It improves maneuverability: a) driver saves time in the movement by getting each speed with zero time of vehicle acceleration and many higher reverse speeds without additional gears; b) it expands the range of speeds up to 272 forward/170 reverse overdrive speeds/torques by adding only 2 shafts to existing heavy-duty truck gearbox of 18 / 2 torques; c) driver uses front on uphill and rear on downhill, or all wheels temporarily for additional saving energy; d) aircraft or watercraft have much increased turning speed if uses it instead existing operation system. 7. Its production uses the same machine tools and other items of existing manufacture. Why is much reduced motor torque or power magnitude? Well-known maximum torque of vehicle wheels is calculated so: friction coefficient (0.7) between wheels and road on stop by weight with biggest load by radius of wheel. Then it by ratio of differential gear and pinion is torque of gearbox output shaft. Highest torque of its input shaft is torque or power magnitude or size of motor. There are examples: 1) Existing transformed non-accelerated heavy-duty truck Volvo VGD has 20 forward/5 reverse torques/overdrive speeds gearbox apparatus comprising 20 gears/3shafts or 40% number of gears and four shafts less than its shift gearbox of 18/2 torques. It reduces motor power in 4 times (500 hp to 123 hp). Driver of the long haul tracking saves above $25,000 per year by diesel ($3) economy in 2 times and saves by increased speed on uphill if it is fully loaded; 2) Existing transformed non-accelerated Toyota Camry could have gearbox apparatus of 12 forward only overdrive speeds/ 4 reverse by 16 gears/ 3 shafts or one gear plus to existing gearbox of 6/1 speeds. It reduces motor power in 9 times (178 hp to 20hp); 3) Existing transformed, non-accelerated CNC Knee Mill spindle joined to automatic programmed gearbox apparatus of 64 torques and overdrive speeds by 7 shafts/32 gears. It joined to Dayton motor of 1/2 hp that replaces expensive programmed motor of 5 hp and could reduce power in 10 times that provide reduced cost in 2 times ($35,560 to $18,000) less. 4) Much lower interior temperature of motor eliminates condition of the harmful gas - nitrate oxides (NOx) creation that is main killer of life on Earth. According to Peter F. Ducker “Business has only two basic functions-Marketing and Innovation”. Expensive machine market is much more dependent to number of customer high-paying jobs and customer’s interest to save health and money than the markets of other products. The crises USA automakers have disclosed the wrong way of machine creations are based on permanent aid by taxpayer’s dollars where “In God we trust” wrote and incorrect information. Human wisdom of past ignores Creator’s Physics Laws of Lever and Inertia in the machine designs are based customer’s interest to save money and health by using more clear air. They created innovations for getting “easy” money by: a) using gas or magnet field for many thousands pounds acceleration; b) using radius of motor shaft as level by directly jointing to wheels or propeller or spindle; c) using each transmission as second brake to the acceleration system that wastes up to 80% mechanical energy in form of motor heat; d) using two clutches with name “automatic transmission of torque convertor and continuous variable transmission” that never get timely higher torque/lower speed before reaction of motor with excessive power. Those are not available any longer. Today the prices of energies, numbers of machines, technical progress, education, global communication, environment disasters and people premature deaths from lung diseases are increased in many times that require to stop ignoring the steel lever in each machine design. Maybe shift gearbox has limited little gear ratio as planetary transmission design or has competitors between existing other transmissions? No, there are incorrect. The pair of gears uses only 2% energy that is least magnitude in the world and it could reduce motor torque in up to 7 times. For example, shift gearbox of seven shafts could reduce the torque of motor in up to 7x7x7x7x7x7=117,649 times but it wastes only 2%x6=12% energy. Please contact me if you are interested in licensing the patents and desire a relationship with me to develop gearbox apparatus systems for existing vehicles, CNC machine tools, heavy-duty equipment etc

I am a high school graduate, but I haven't gone to college yet. However, I have the thought experiment that allows me to figure out ideas, including a wide range of details, big and small, without a physical demonstration, or taking a class for it in my life. So I have a lot of certainty, although no experience from school or college. I have skill in checking in all the choices I have, big or small, and putting them together and finding a solution. With all this, I have ideas for how the transatlantic tunnel could be much more reachable in modern science, technology, and more affordable, or profitable. How the tunneling by itself could be completed within a decade, no water/weather/temperature challenges, less dependantcy on steel mills, and less shipping. Also how the cost could be dropped by 5 times, possibly more. Also ways to charge passengers that could mean a faster rate of recovery of the cost of everything payed to build the structure. Also ways to reduce g-force effects and without cutting down passenger capasity and without additional power cost. The total cost might be dropped down by 90%. But the beginning of profit earnings might still be a long time away, but the reducing of 90% would be a good head start, considering the economy. And on their way, time will tell if the cost dropping of 90% will increase to 91% or more. There will always be time for another drop. Never too late, even though the sooner the better. Even if the economy improves. Money/profit is the goal. Never lose hope for a better future. That's how I think about it. But would they believe solving these challenges I mentioned, especially the cost, should make the Transatlantic Tunnel reachable enough that it would be no more hazardous as the Bering Strait Tunnel, considering the cost and dangers of building thousands of miles of railroad from both ends added together?

The first mistake was taking a way NASA's budget. The second was assuming that it was right to do so. In the next 50 years space mining and exploration will become key fields of industry... but only if the rates of engineering innovation in this field increase. This is a valid and key field of interest partially because of the hunger for resources, partially because of the inevitable population cap, and most importantly because this is the "final" frontier,,, as engineers we are obliged to construct sustainable and cost-effective methods for prolonged space-industry. This is not science-fiction. this is reality

Some human fundamental ideas have no history. Kopernik merely recollected Pythagorean idea from forgotten litarature, but not from astronomical studies. Similar ideas/archetypes exist in our memory.Hence, Some discoveries are just recollections. To activate our X - memory is to make discovery. This is banned Platonism. We reject it as a nonsense. There is forgotten techniques to make such sort of discoveries -as-a-recollections. I suppose that only Engineering practitioners can provide such research.

Hi, I reached here via InnoCentive. Why we only think about an economic solar electricity. We can think other way to use the solar energy efficiently. I'm not an engineer or reasercher. I have a doubt that why we are not combining the technology of Absorption refrigeration system and Solar energy. According to my knowledge, Absorbtion refrigeration system only researched or used by Japan or Korea. Why other contries (Companies) not using this technology. If we combine, Solar and absorption refrigeration system for Airconditioning at least in Day time, we can use solar heated water for heating the generator of absorption refrigeration plant and Solar electricity for pumps. That means entirely grid power free airconditioning for sunny and hot areas like Northern India. I think no need of drastic changes required for this. Already absorption plants using hot water, hot air or steam for heating the generator of the absorption refrigearation plant.

Thinking outside the box, new approach to “flushing”: What better way would it be if we “flushed“ our toilet with Air instead of using water and wasting water (which is mostly drinking water) to transport our “message” from A to B. From A, the toilet to the B, the wastewater treatment plant. By flushing with Air we save an enormous amount of water only less than 1 litre is used to flush instead of 15 litres. Imagine a boarding school with 500 students. Water to flush the toilet is normally 7500 litres per day, this is 1.875.000 litres per year. With Air this is only 125.000 ltr per year. 93% savings This way we would not need any expensive waste water treatment facilities that only consume energy. If We collect all this organic (faecal) matter ("blackwater with a minimum of water) and digest it in an Anaerobic digester with all organic kitchen waste, from preparing the food and the returns / leftovers, we can produce methane gas for heating /lighting or cooking In the Anaerobic Digester all organic material is digested by Anaerobic Bacteria and Biogas is formed (Methane and Carbon di Oxide). This Biogas can be used to burn and cook the meals or in a heating system. The amount of Biogas generated is approx. 20 litre per day per person. A boarding school or hotel with say 500 people/beds would produce ca. 10.000 l Biogas/day. ENVIERHO AQUA PROTECT ‘s intention is to market and sell vacuum systems linked to an Anaerobic Digester that will produce methane gas for heating and cooking. This concept could be easily implemented where we have a concentration of people. - Large boarding schools with canteens. - Larger cluster of apartments. - Prisons. - Large hotels with restaurant - Hospitals with kitchen. - Cruise ships. - Larger camping sites. - Holiday homes clusters. - Army Camps - Refugee camps To get this concept implemented a Pilot Scheme is required to proof its viability.

Hi, I followed the path from Innocentive. I was interested in healthcare and I have been working on something myself. There are certain areas where I lack experience and doing this alone will likely take a long time. Let me tell you one of my visions. I got physically sick around 3 years ago. My dad had a heart attack. My mom was already having health problems. I want to help the world learn how to eat again with the various health conditions. I believe it is possible to write a computer program with all of the nutritional data we have on food and disease. This program that I am thinking about would hopefully be able to give a patient the knowledge they would need to eat healthy with whatever ailment they are experiencing. It would also allow people to make the food banks of better utility for those in need. When I had to use a food bank I ended up giving some of it away because of my sensitivities. If we could find a way to feed the most people without the likelyhood of causing a reaction or health concern, we could utilize the information to help the food banks as well as oversea hunger problems. I suppose I am dreaming of software that would take a lot of data entry. I do not know where to find lists of premade data tables that I may be able to use. I also do not know how to write the program in computer language. But, I do know it will likely take me much longer to do this on my own. I have many ideas but I am not sure where to give them away or where I can find help in implementing them. I am also unsure of where you could go to submit for challenges.

For provide access clean water it is nessacary Water Treatment Plants correct design. A main unit of that Plants is Settling Tanks or Sedimentation Basins because there are detained about 95-96% of suspeded solids. But Settling Tanks design has a great problem at the present time. The reason of this is next: more than 100 years ago was developed traditional(conventional) theory for Settling Tanks design on the basis of the Newton gravitational law and Stokes equation. But thanks to this theory it is impossible to calculate the sizes of Settling Tanks and to create models of them and to choose effective one. It is unbelieveable, but for Settling Tanks depth calculation all manuals and books are recommending "ideal sedimentation basin" where settled spherical particle . That theory is very effective for chemists, biologists, but not for engineers. For decision above broblem 1991 the I developed Alternative Sedimentation Theory on the basis of the Newtons Second law: http://knol.google.com/k/sadyrbek-djighitekov/alternative-sedimentation-theory/1cs9gt8jgdjvm/9# Example for Rectangular Tanks design is given on the web: http://knol.google.com/k/sadyrbek-djighitekov/settling-tanks-basins-design-on-the/1cs9gt8jgdjvm/2# Everybody can visit to discussion forum too: http://www.waterandwastewater.com/cgi-bin/yabb/YaBB.pl?num=1232599276/41 - On the basis of the Alternative Sedimentation Theory it is possible Settling Tanks Design accurately; - Thanks to above theory it is possible to create models of Settling Tanks types and to choose of effective one; - Alternative Sedimentation Theory is very effective for students of the universities for clear understanding of Settling Tanks Design; - That theory give a great opportunities for management of water and waste water treatment plant for economy chemical coagulants or improve sedimentation process in Settling Tanks. The conventional(traditional)sedimentation theory can not give above opportunities for scientists, experts, engineers, and students.

I am promoting inventions in the field of engine-building. At present there are issue international patents for two inventions. The core of know-how is a completely new conception of structure of internal combustion engine. This is not a technology, but this is a new and fairly simple principle of structure of an engine without using a crank mechanism. The inventions are at the "Idea and research" stage, but for technological implementation there are required a lot of funds. Concerning know-how advantages: The project can be considered as a social one as it has a direct relation to reduction of CO2 emission to the air. The principle allows to construct an internal combustion engine in such a way that combustion mixture can burn down almost up to 100%, thereby it helps to minimize CO2 emission. These decisions are in no case reflected on engine power, even vice-versa increase indicated power two, three, four times as much reducing fuel consumption at the expense of structure downsizing.

Consumerism is the root cause of most of our climate and social issues. There are the few who can afford everything in excess and the many who can not afford even the basics. The poor destroy the Earth by trying to survive while the rich benefit from such destruction. Before we take on any challenges, we need to educate the masses to reduce consumption. All great technological innovations need to have a social understructure to function. It would be great to have new sources of energy, but we all know it comes with a price that someone sets to profit themselves.

Sincerely Byeungok Oh (lccobok@yahoo.co.kr) L.C.C. life environment research institute 10-9 haewhadong jongrogu Seoul 110-530 South Korea Attched: Medicine improvement by the artificial mitochondria that come true newly It does not realize between continuous time passes and energy balance equilibrium state is kept constantly. To hang in physiological function of cell overly and Purpose function of cell being not grasped, it is foreseen that fair flustered feel will go first that artificial mitochondria device is pronounced. Substance of energy is managed by some route anything really? But Question can go first. As present drug stuffs form, even if energy utilization state is microbial outgrowth unit or is used in human body by herb medicine ingredient unit customary. This very small quantity being used and Change is various kinds thousand that is accompanied here. Specially, human body sees as is reacting in always fixed form, but it is not equal feedback. As form one@ circulation, because keep feedback. Although it is difficult that present model of some form, Unit model circumstance disposal is much easier if is mixed as complex and it must to be always fixed do according to last presence at a clinical result and keep this level. System function weighs so far and although spoke that reaction for this function is important, because all situations are variable, it was not agreed easily. Energy generation that is human body main reaction, nutritive substance transport, exchange, reaction path connected with excretion create and disappeared thing is situation occasion although it is suspended if do even if full . These situation cell or the formation agency of as function originally, All components are wormed orderly. But, it must atomize here much more and examine. It must divide condition and human body formation physiological function that human body formation component is arranged with optimum function preservation. Otherwise, fall at discord if it does not adjust balance even if it is emphasized one@ side. It arrives in one@self own collapse. Alternate the formation agency of corresponded part when is such. Although it is preferring excessive method to rescue function, is not problem solution. Because controversial point of inside is indwelled. . Also, it is going to have a hasty decision to remove own collapse part, but it is temporary expedient as well as this. As see while it does, it can not equal super computer how much compensated organization and institutions are how bulky. By the way, it is great development that chases gene change recently and arrives in disease treatment. Although minuteness diagnosis and assay can be available to micro tissue overly among these trends, it is very inefficient. Also, in such a case it is thing similar to very inappropriate disposal situation in acute situation of system control command department. If one@ is spot responsible person, how does it may control? It must connect being detoured if nerve control is problem. Organization need to do construction in beam style support thing by urgency processing if it was damaged. After it handles surgical situation of these method, Energy supply of drug delivery way follows. This method is being not becoming minuteness control entirely. Still, it guides to organization which become an issue like missile and Do even if do so that effect may appear time lag like time capsule shape, it is going to minimize drug stuffs side effect, but is the station tribe. Still, improved a little, the effect preservation is limited extremely and can not escape limit situation. Also, change by special skill that is contributed by one@ expedient and is getting stabilization easily. However, mechanical heart industry falls in stagnation representatively, is staying in presence at a clinical level continuously. It is a little inconvenient in recent science level. All sides of human body are stagnated and are degenerated but It must define state that is gotten back in various disease syndromes clearly newly. It is not gotten back that get travail effect by some drug stuffs taking medicine. It is not gotten back that cut formation which function is suspended and is collapsed by radiation and remove by surgical operation. So, although party satellite of rehabilitation medicine will be formed, We must supervise responsibility why we aggravated situation in this way. Gene defect is indwelled because disease symptom is not come to the fore, time passes Or, economical reason can be. At the some moment, patients who appeal bodily languor can lift that is many. It is most workpeople, but because connected production efficiency drops rapidly. Even if severe labor condition is improved by much production facilities automations, It been going side by side business stress can not avoid and hygienic condition is worsened remarkably. As it is going to minimize life risk to various kinds economy leading composite index, weather forecast information etc. present, it must hydrate health information since and do life. If discomfort index is high, human body atomizes health index as operate air conditioner It should be forecasted commonly and should be managed. So, important health power of a number will be judged that is managed by a constant time medical examination, but it is big mistake. And method that can get health improvement from a medical examination is ephemeral as method or kinesiology experience and is not forming system. This state can announce health safety low limit critical state. This moment is overlooked mostly and is not managed. So, by suitable model system operation administration although took example. is similar to be difficult to do to recognize situation. But, if onc@e more example to be delayed constantly if exchange battery, watches the effect prove. Similarly, level should be kept as summit human body is that human body use artificial mitochondria device. Therefore, what is free energy from metabolize energy level change and essence being, what is achieved career. Important bolt is going whether is regulated in some route and is gotten back. So, it is thing which gives a name as artificial mitochondria device and proposes and does. But, medical world expects thing supplied freely cultivating trunk embryo bud cell. If speak as artificial, although it can do that is not clinical two like mechanical heart and do inquiry, To embryo bud stem cell keeps stationary state, minuteness environment should be supported. It can not overlook level is free energy that is happened in metabolize energy, can not be formed altogether. Also, human body as system is ATP energy supply and demand situation forecast can, It does not examine closely ATP energy essence continually and is grasped that is energy that is happened in conversion between ATP and ADP. Nothing is marched in this state. There may be composure yet When blow upon critical, situation can not estimate roughly by special quality half-life if pass a little. Have you to abandon still? By automation already in system control command room system safety run, In human body system any confrontation do not ready also action step ready. If see the main mitochondria function, If oxygen per alveolus, enzyme etc. that is carried in blood is supplied and is assimilated to mitochondria like sponge, expected compression heat occurrence effects are accompanied. So, energy is stored to ATP, energy supply and demand circumstance becomes very unstable as for this path. And it can say as formation agenciesf physiological function that reaction action is gone by ATP system energy supply. Energy source should be supplied and is overlooking by bigger efficiency than this. So, when explain applying by system model, agreement does not become. Therefore, energy save medium and career are defined newly and are normalized. it can help function in human body that do artificial mitochondria energy development device. Is ideological and abstract yet? Because adjustment is available onl@y energy career Indiscretion energy avoids side effect being supplied like covenant. First of all, it is energy save medium. It speak that energy was stored in fattiness quantity, but direction energy supply medium is not examined closely yet. Such series process can assume easily to system administrators and is grasped. Although reposed wall one@ is human body cell and another is never easy to fusion each other as is the inorganic matter molecule world According as career of energy supply process and common homogeneity of medium are embodied, the importance of fusionfs learning is emphasized. Although it is applied by various kinds field, Because focus and examine again, is participated together and when standardization is gone ahead Human health contribution becomes advance.

I think engineering can, for one, help the economy. Well, right now there only a few things that could accually HURT it, if you know what I mean. But also I beleive that it helps in four other areas: Entertainment, Experience, Saftey, and Productivity. I just saw this thing about this engineering company in Germany that created a mechanical flying penguin. They said it could be used to deliver mail, wich would be okay but more to humor them then anything, but if they began selling those on the market, that could really encourage the younger generations to go outside and run after them, because, what's a TV compared to a flying penguin? Engineering could work in the opposite way, too, though. Also, experience. There would be so much different variety in life if you technology that alowed you to do things you've never done befor. Thirdly, Saftey. What if car crashes became so strange that they happened once a year? I'm reffering to pre-existing tecnology that people use on a daily basis to be improved. I'm not saying that it would be good if they invented aa chip that goes into your head that stops a murderer from killing someone. And finally, productivity. Faster things being made, stronger things being made, stronger alloys being formed, deeper caves being dived into, faster ships bringing human life to study mars, more accurate weapons to nuetralize terrorists and not their hostages. There really aren't many ways for advances in technology to NOT help society. And, no, I really don't think that technology will be taking over.

However, mechanical heart industry falls in stagnation representatively, is staying in presence at a clinical level continuously. It is a little inconvenient in recent science level. All sides of human body are stagnated and are degenerated but It must define state that is gotten back in various disease syndromes clearly newly. It is not gotten back that get travail effect by some drug stuffs taking medicine. It is not gotten back that cut formation which function is suspended and is collapsed by radiation and remove by surgical operation. So, although party satellite of rehabilitation medicine will be formed, We must supervise responsibility why we aggravated situation in this way. Gene defect is indwelled because disease symptom is not come to the fore, time passes Or, economical reason can be. At the some moment, patients who appeal bodily languor can lift that is many. It is most workpeople, but because connected production efficiency drops rapidly. Even if severe labor condition is improved by much production facilities automations, It been going side by side business stress can not avoid and hygienic condition is worsened remarkably. As it is going to minimize life risk to various kinds economy leading composite index, weather forecast information etc. present, it must hydrate health information since and do life. If discomfort index is high, human body atomizes health index as operate air conditioner It should be forecasted commonly and should be managed. So, important health power of a number will be judged that is managed by a constant time medical examination, but it is big mistake. And method that can get health improvement from a medical examination is ephemeral as method or kinesiology experience and is not forming system. This state can announce health safety low limit critical state. This moment is overlooked mostly and is not managed. So, by suitable model system operation administration although took example. is similar to be difficult to do to recognize situation. But, if onc@e more example to be delayed constantly if exchange battery, watches the effect prove. Similarly, level should be kept as summit human body is that human body use artificial mitochondria device. Therefore, what is free energy from metabolize energy level change and essence being, what is achieved career. Important bolt is going whether is regulated in some route and is gotten back. So, it is thing which gives a name as artificial mitochondria device and proposes and does. But, medical world expects thing supplied freely cultivating trunk embryo bud cell. If speak as artificial, although it can do that is not clinical two like mechanical heart and do inquiry, To embryo bud stem cell keeps stationary state, minuteness environment should be supported. It can not overlook level is free energy that is happened in metabolize energy, can not be formed altogether. Also, human body as system is ATP energy supply and demand situation forecast can, It does not examine closely ATP energy essence continually and is grasped that is energy that is happened in conversion between ATP and ADP. Nothing is marched in this state. There may be composure yet When blow upon critical, situation can not estimate roughly by special quality half-life if pass a little. Have you to abandon still? By automation already in system control command room system safety run, In human body system any confrontation do not ready also action step ready. If see the main mitochondria function, If oxygen per alveolus, enzyme etc. that is carried in blood is supplied and is assimilated to mitochondria like sponge, expected compression heat occurrence effects are accompanied. So, energy is stored to ATP, energy supply and demand circumstance becomes very unstable as for this path. And it can say as formation agenciesf physiological function that reaction action is gone by ATP system energy supply. Energy source should be supplied and is overlooking by bigger efficiency than this. So, when explain applying by system model, agreement does not become. Therefore, energy save medium and career are defined newly and are normalized. it can help function in human body that do artificial mitochondria energy development device. Is ideological and abstract yet? Because adjustment is available onl@y energy career Indiscretion energy avoids side effect being supplied like covenant. First of all, it is energy save medium.

Everyone keeps saying " Wouldn't it be nice if only . . .but not many people actually work at the problems on their own account. Yet, there is an American and Western-Civilisation tradition for individuals to tinker with hand, brain an own resources to meet problems head-on by solving them, first in a small way, then all the way. I can quote names like Joule, Watt, Edison, and Ford, which leaves out multitudes of those who made it and of course, those who gave up before they made it I have a serious "work-in-progress" proposal for a "solar energy combine harvester", some definite details of which are already disclosed on my blog with "engineering.com". To anyone who back-tracks these disclosed details and wants to know more, I will answer with facts, figures, text and pictures from my open "Project Portfolio". My target, to be actually demonstrated at artisan scale with models I personally build, is : concentrated heat resulting from 70-times concentration of rays, at a cost of 10 US cents per kilowatt hour. The heat is then to be converted into electricity by a reciprocator directly powered on the sun-follower rig, via pneumatic or compressed air that drives the rotary electric generator. Evidently, a working- fluid is heated in a very innovative concentration target, - water-steam or hot-pressure air both suitable. A payback of investment within one year is plausible, but has to be proved. Completion target for my end of the project - midsummer 2011.

I completely agree with Peter from Arizona. Living in a country when the Sun beats down throughout the year, I am appalled at the minuscule number of solar panels I have seen. I know that they are hardly efficient due to the lack of intensity per square area, and that they very costly, but, as Peter said, this is one resource, i hope, the world will NEVER run out of. You could also use solar panels on vehicles, be it on road, water or air. This can greatly reduce fuel consumption => not only does solar power have its own advantages, it also cuts down disadvantages of other power types. SOLAR POWER ftw

Although water is the one of the most abundant compounds on our planet, the supply of water for human needs is very low, so engineers need to be responsible for improving the supply of drinking water. One idea that I thought deserves investigating is the low-energy production of clean water using forward osmosis, where saline water is brought into contact at a selectively permeable boundary with a more concentrated solution with certain properties. The water moves by osmosis into the more concentrated solutions, but the solution has properties such that the solute will vaporise and be given off by simple heating, producing pure water. (Or equally I thought you could use concentrated nutrients solutions, to avoid neeting to remove any solute). I agree with whoever mentioned overpopulation problems, but the only ethical policies for solving that (i.e. limitations on no. of children) require the implementation of politicians rather than the ingenuity of engineers.

I believe that in order to become more sustainable we will need to harness solar energy. This is the only renewable energy source that is common everywhere. If we can create more efficient solar panels then we can reduce use of fossil fuels and lessen our carbon footprint. I also believe that the introduction of switchable glazing windows, which can reflect 90% of the suns rays, into homes and businesses can reduce energy costs dramatically. Also if we can implement solar panels into windows this would allow for much more renewable energy. Creating solar panels that are able to function as windows would allow solar panels to be in glass buildings, cars and homes.

I have seen a few post mentioning this, but would like to state it again, explicitly. By focusing our efforts on advancing solar energy, wind energy, hydro energy, wave energy, geothermal energy, etc, are we not building a burden to carry in a few generations' time? Considering 'localised climate change', if we harness all our energy requirements from the elements, we might be affecting a balance that we as yet are not comprehending, nor will be truly comprehending until we have significantly changed that balance. Hence as much as fusion seems the old school choice, it seems like to more sustainable choice.

Complete Automation Based On Self-manufacturing General Purpose Robot Post-science provides the foundation for complete automation. Complete automation starts from the Self-manufactured General Purpose Robot with the ability of touch (coming safely into contact with an uncontrolled environment, as human, animal, and insects can do). The Self-manufactured General Purpose Robot is manufactured by itself and, with the ability of touch, can perform general duties and, thus, can replace all human physical labors, as machines have replaced animal labors in the Industrial Revolution. To finance the development of the SGPR (Self-Manufactured General Purpose Robot), the automobile industry provides an intermediate stage of application, which can justify the development cost. The main improvement will be the active shock absorber, which will give a competitive edge to the automobile. The active shock absorber will allow the car to travel on rough road and to make driving far less tiring when all the shocks have been eliminated. The active shock absorber will transfer the stress on the tire to the jumpulse mechanism, which is the key ingredient in preventing bounces. Thus, it will lengthen the useful life and reduce the manufacturing cost of the automobile tires. Most likely, the smooth ride could greatly increase the gas mileage. The feasibility of the active shock absorber has been experimentally demonstrated by mogul skiers, who can come down a bumpy hill in a straight line, while their legs go up and down executing jumpulses. Similarly, touch, collision without bouncing off, and prolonged contact in racket sports need the application of jumpulse. Post-Science Institute has solved the problem of touch, using the concept of jumpulse, an instantaneous change of force, while Isaac Newton and all the physicists since Newton have not yet fully realize touch is one of the most subtle problems in mechanics. A robot finger bounces off a surface like a ball bounces off a racket; jumpulse is needed in both touch and prolonged contact. To be completely automated, the Self-manufactured General Purpose Robot is constructed by the software programs which instruct the Robot to self-construct. In other words, the construction and modification of the Robot are done at a computer terminal. The robot software used should be completely automated, in particular, allowing completely automated updating from old to new versions with new functions. Thus, the other big innovation in complete automation is the completely automated software. Homotopy Graph Theory of T. L. Kunii will be useful in drawing the Robot. Homotopy Set Theory of Kunii provides an efficient mathematical foundation for complete automation. The solution of value of Hugh Ching will be needed to determine the value of the Robots. Richard Stallman and his army of Free Software programmers world-wide can rapidly convert the current partially automated to a completely automated software standard. Post-Science Institute would be willing to release the fundamental patent to the Free Software Foundation so that both the economic and the technical barriers to computer usage will be eliminated at the language level under the completely automated software standard. All people around the world over the age of six can start to program a completely automated All People Programming Language, which will communicate with its users in their native language or even graphics and sound. When the Self-manufactured General Purpose Robot is available for programming, everyone can have a job programming the Robot. For example, a car will be manufactured by simply push a button ordering the car to be manufactured. Today, in Japan there is already an electric fan factory, which is almost completely robot controlled. With the current financial crisis and with the automobile industry falling a victim to the economic downfall, our world has an opportunity to revamp the entire automobile industry, with public investment and, possibly, a world-wide initiative. Turning the automobile industry into a robotics industry might be the first step in the human destiny toward a completely automated technology. World political leaders should have the wisdom to see this opportunity. This huge project is blessed by the spirit of Ta-You Wu, who coined and defined the term jumpulse.

Use software engineering to provide for the following to come true: Capital markets are unstable. In the past there was no way to make them stable. But today we have computer power that can be used to make them stable. By using the greater computer power of today we can have a much higher turn over of capital in the capital market. This higher turnover will make the market harder to game or control and the market will no longer have the unstable run ups or declines. Who can change or control the market when say 20% of the capital is trading each day? So now that we have the compute power to provide for all these transactions that will smooth out the market how do we force people to turn over at a rate of 20% a day? Easy, put a cap gains tax of 0% (zero) on all gains of 7 days or less and put a cap gains tax of 90% of all gains of more than 7 days. The likes of Yahoo, Micosoft and/or Sun Micro Systems will give us the systems that will provide automated software agents to support turning over one's investments every 7 days (based on the specs you give the agent).

Problem: Limited fresh clean water Solution: The transport of melted Iceberg water from the Southern Hemisphere to America. Engineering can help America by developing the simple technologies of gathering, transporting and distribution of iceberg water from Mega icebergs that have run aground in the Southern Hemisphere around the 57 latitude. Iceberg water is a renewable resources and recognized as such by academia and the UN. Melting iceberg water can add to Americas fresh water resources. Giant fresh water tankers driven by photovoltaic cells and other eco-friendly power sources can economically supply an endless need for fresh drinking water not contaminated by industrial and pharmaceutical pollutants. Recycled drinking water does not mean clean water, its just water that meets a lower standard. Iceberg water does not mean the continued wasting of water only the expanded supply and the possibility of better water management. Right now all we are doing is recycling not expanding our water supply. Technology can only do so much. We are slowly poisoning our self's with recycled water just like the Romans did with Lead pipes. Think about it!

I was told Mr. Raymond Kurzweil that reverse-engineering of the brain is impossible and unnecessarily task. There I will provide some details. “The plan is to engineer the mind by reverse-engineering the brain,” says Dharmendra Modha, manager of the cognitive computing project at IBM Almaden Research Center.” Reverse-engineering of the brain is impossible task. The brain is a dynamic structure. Dynamic of the brain structure is reflecting condition of a body where the brain is seating moment after moment. That will bring requirements to model a brain as whole in time short enough to make that structure pseudo static and link that structure to history of the body. That is important restriction. Brain structure is reflecting conditions of the body and did not have links to conditions in the environment. That is enough to make reverse-engineering of the brain impossible. Why that task is unnecessarily? So far no one attempt to build the human hand like printers. The same is with a brain. We have to build the devices with functionality of a brain. That is possible to accomplish on the base of a conventional computers and I know how to do that. Be my partners. Michael

Asteroid/Comet Impact Prevention is an "insurance policy" for civilization. http://legendarypharma.co m/jdf/impact.html In our Solar System, each of the planets is hit by large, high-velocity rocks at unpredictable times. A meteorite which is 50 meters (150 feet) or more in diameter can wipe out a whole city. A larger meteorite hitting the ocean would cause tsunamis, huge waves which could wipe out all of the coastal cities on the shores of that ocean. A meteorite several kilometers in diameter (more than a mile) would cause global firestorms, trigger massive earthquakes, volcanic eruptions, and tsunamis, and terminate human civilization and most "higher" species of life on Earth. If a comprehensive sky survey were in progress, a threatening asteroid could be discovered months or years in advance. If diversion planning is begun in advance, then the longer lead time could be used to send up a rocket to divert an incoming comet before it strikes the Earth. The expense of such preparations could be justified as buying DISASTER INSURANCE or implementing safety programs. We need to scan the entire sky every month. Long lead times are essential to successfully divert these objects to safely miss us. PARABOLIC COMETS (Long-period comets) are a special threat because: **They come through the Solar System only in once in human history, so we have no historical records by which to predict them. **They can come in from any direction including the north or south pole. **They come at extremely high velocities (50,000 miles per hour). **They are very large. **They could smash the Earth on their FIRST PASS through the inner Solar System, so we don't have lots of time to calculate their orbits. Hence the NEED TO SCAN THE ENTIRE SKY EVERY MONTH

If the Administration wins its battle to cancel the Constellation program then how many young engineers does that affect when it comes time for them to select a program of study? How many students will choose other degrees outside of engineering and technology? There is already a lack in Aerospace Engineering graduates in the US today. According to current NASA Science and Engineering population statistics, nearly 87% of its workforce is of the age 35 and older. Of that 87%, 45% of those individuals will be eligible for retirement within the next five years. Young engineers who were motivated by space exploration and the dream of one day becoming an astronaut have just been removed by this Administration. How does canceling American’s spaceflight program improve our current education and workface gap in engineering and technology? It doesn’t! The number of predicted jobs for commercial spaceflight is less than the number of jobs that will be lost in canceling Constellation. Where do those young professionals go? By losing them you’ve just increased the time it will take to send American’s to ISS or beyond LEO. Where do you stand????

Post-Science Institute has solved the problems of completely automated software and touch, or collision without bounce. The following is an explanation of the significance and the technology of the software: Of all the advantages in software design, none is more important than the design requirement of permanence achieved through complete automation, a lifetime unfinished goal of John von Neuman, the inventor of the computer. Generally, a permanent entity will someday be infinitely more valuable than a temporary entity. In fact, permanence could be the only discipline of its own for computer science, and is the main characteristics of life science, which can be defined as the programming of DNA, the prime example of a completely automated software system. The condition of permanence is achieved through endless self-generation and automatic updating, which are necessary features of complete automation. Without auto-updating, nearly all the software budget today is allocated for software manual updating. The three main innovations in the completely automated software are (1) Universal User Interface, (2) Universal Computer Source Code, and (3) Universal Data File, the last of which has been thoroughly examined by the patent examiner for the completely automated software “Self-generating and Completely Automated Software System” Pat. No. 5, 485, 601 and only needs to be understood by technical people. Just the first two innovations should provide a convincing argument for the absolute need of the completely automated software. Universal Computer Source Code is simply integers from minus to plus infinity. The completely automatic manipulation of integers by the computer is the key to complete automation. The Integer is the natural language of the machine or the computer. DNA, represented by 1, 2, 3, and 4, is the ultimate example of Universal Computer Source Code. However, the integer representation of machine instructions is hard for the human users to remember. To minimize the technical barrier to computer usage, instructions should be explained and documented in human native languages or universal symbols. Universal User Interface is a tree-structured, numerical multiple-choice question format, which allows the human user to understand the questions expressed in human understandable expressions and the computer to handle the integer answers. Humans have been created with the ability to remember an unlimited amount of information through Universal User Interface, which groups similar items in the same branch of the tree-structured multiple-choice questions. This ability is related to the Human Associative Memory, which allows the human user to retrieve an unlimited amount of information from a computerized library catalog and gives humans the capability in their self-creation. The completely automated software will bring about a technical breakthrough of historical proportion, even exceeding the significance of that of the Industrial Revolution. In addition to bridging the gap between human technology and creational technology, the completely automated software, with the elimination of all the technical barriers in computer usage, will make the tangible contribution of full employment, one of the ultimate goals of economics.

In my opinion, there are hundreds of ways that mankind can use its resources in a more efficient and eco-friendly manner. It is more an issue of general knowledge and awareness by the public, coupled with favorable economical and political policies to be implemented by governments and multinational corporations. I´m particulary interested in the supply of clean water to the population, specially those who can´t afford it or are geographically distanced from mayor cities. A lot of these technologies already exist but are not being implemented either because there is a lack of budget or action by the government. Relatively cheap forms to accomplish this if by using surfaces or devices that capture the water vapor from humid air and condensate it to liquid form. This is a simple yet effective way to obtain water from the air (a source that is present in abundance). In addition to this, there is a huge development in water filter by using ceramic filters or activated carbon. It is important to take into account that these methods are not energy demanding such as reverse osmosis or desalinization plants, and could be supplied (transported) easier to populations in need, for example in the current situation in Haití.

"The biggest problem with this is not that we do not know how to purify water or help prevent disease, but rather that we do not have efficient systems to transport our help to these areas." 

I believe that the first step to answering these questions is to identify our most pressing problems. While there are many out there and many great minds to focus on them, I believe our most pressing human problems begin in the areas that cannot gain access to healthcare, clean water, and other essential needs. The biggest problem with this is not that we do not know how to purify water or help prevent disease, but rather that we do not have efficient systems to transport our help to these areas. If we can develop technologies that can be airdroped or distributed in more efficient ways, we can make all of the knowledge and resources we have more useful to all. This is one of the weakest links in the system and therefore I believe its one of the places we need to focus the most effort.

My idea might well fit inside the pages of "Energy and Transportation: Challenges for the Chemical Sciences in the 21st Century" I propose the Glass Highway for America's transportation needs. A computerized electrical highway system that will power America's electric cars at 200-300 mph. The cars will be eco-clean & not even require a battery. The roadbed will be made of 50' sections of 2-3 foot glass (from melted sand) embeded with reinforcing, electrical conductors, a car slot, and communication wires. Massive machines will make the panels onsite and lay the 6 lane glass panels, 2 to a section, 6 lanes going, 6 lanes coming. The power will be supplied by 100 nuclear reactors built on each of our three coasts, to power America's future. Next to these will be built desaltination units, running fresh water by piping into the arid interiors of America. The nukes will also be hooked into the electrical grid to lower industrial costs, farming costs, domestic costs, and the glass highways. Overall, this project would eliminate our oil dependence, provide cheap consumer products, help us compete with the world, provide jobs, stop killing Americans due to exposure, and take our workforce to work at high speed uncongested highways. Thank you.

Title: On the quantum theory of Einstein's argument for the Analysis of 0. Introduction. The universe, in nature, natural phenomena should be similar, only the material universe, the formation of different density and structure of the different quality of performance, makes us feel amazing. 1. Nature of matter and energy. High and low quality material and the formation of high and low speed compression level of energy; promoting the synthesis of high-density material, decide the level of synthesis of high energy density material, high-density substance that is very low or lower the quality of countless particles of compression; promoted by the need to promote the same level of energy ; impact the level of decomposition of the quality of the material synthesized particles can be high-energy particles of synthetic material to lower the quality of decomposition of the small particles, and to promote particles of high-speed movement, high-speed movement of very small particles can enter the high energy density material, in collision of high-density material; arising from the accumulation of high-energy, at the same time, external high-energy to promote accumulation of material arising from the energy of movement of high-energy, high-density material and there must be space, ultra-high energy can be broken down into very low quality of the material particles, the level of energy; quality is endless. High-quality high-speed movement of material will be high-energy friction material into a large number of low-quality particles. From sub-atomic. Proton. Electronic components, neutrons from a number of electronic synthesis, the electronic energy by the atoms inside and outside the movement to promote. Pressure by the weight of the material compression; energy thrust; cold reaction; by Block, and synthesis of particles of different densities; structure to properties of atoms to the material. That is, the weight of the pressure of compressed high-density material is the weight of the material particles will be compressed in many high density, the thrust of energy that is the level of high and low quality of the material of the high and low speed movement of material particles of energy to promote compression, thermal expansion or movement of many particles of high-speed collision of the energy generated material composed of particles or the expansion to break down the material into a soft particles, condensation or low-energy composition of the material so that many static and rigid particles, the seat edge to promote material that is, when the particle energy must be blocked high-density substance. The level of quality that is composed of atomic particles to the most basic unit of material. The performance of different high and low quality of particles mixed into cells of different density and structure of the cells to the performance of different properties of plants; biological. Cell density of the material that is the quality of cell synthesis of the energy density of the material. High-density material, the more the number of particles needed to effectively break down a certain energy degradation, it is difficult or slow low-energy decomposition and degradation of high density material, low-energy decomposition of the material can be friction and low-quality particle surface. Low-energy particles that is low-quality low-speed particle movement, the collision can not be strong; friction particles of high-quality synthesis of high-density material particles and decomposition of energy to friction. Synthesis of the material structure that is formed between the material particles of the gap; gap, different high-density mixed particles, very low quality synthetic particles of different density and body-like particles of higher quality. High density of different body shape and different sizes of particles of numerous kinds, and different properties of particles of different properties of synthetic material. Light in different density and structure of the material to produce different colors, different properties of density and structure of how much the quality of the material can absorb light. Some high-density material; tough; high temperature, some soft; Some have toughness; Some are flammable, such as gunpowder; oil; iron and steel; the density and structure of plants. Crystal structure that is the gap between numerous particles, particles of low density between the meson, photon - particle easy to penetrate. Flammable material that is the synthesis of particles of lower density, low-density particles have a more low-density particles as a meson, easy to make high-energy particles flammable and low-density energy. Internal high-density material to high-quality, by the energy of the particle movement to promote the accumulation of more rapid movement of the particles can not be released outside the accumulation of high-energy, external energy to promote the accumulation of internal energy arising from higher energy movement. Such as external temperature and low temperature heating and cooling have a role. The star of the heat energy will be broken down into very low quality of the material particles, the energy limited the promotion to a certain distance, some by the energy level of the quality of the material to enter the collisions between particles have high energy, the energy accumulation of material by the external energy to promote movement and rotation magnetic field energy to other particles in order to capture higher quality, and some material with the release of the laws of celestial bodies to run to run, and some substances absorb their own magnetic field, and some other substances with a strong magnetic field to capture the stars. Particles composed of material for the production of heat and friction of the source, the weight of the pressure of compression and friction, energy and the friction of the thrust to promote (a large number of high-energy particles into the material with the friction; the formation of high-energy collisions). Stars within the field of high energy can not be effectively released by rotating the external energy to promote and stimulate the outer stellar particles that form a magnetic field, the solar system by the energy and the activities of the Milky Way, the Milky Way galaxy by the greater energy and the activities of ultra, ultra outside galaxies greater energy galaxies unclear. Galaxies in the deep air support there is for energy, the universe, there is also in deep energy for air support. Nature, ultra-high energy density; structural material performance, ultra-low energy density; the structure of the performance of the material also. The galaxy; objects should include the quality of the sphere of influence of its magnetic field. Uneven distribution of the material universe, there is the level of sub-stellar quality, high-quality energy generated galaxies - magnetic fields and the release of lower-quality energy dominated galaxies, stars and galaxies to promote the activities and operation of the energy that is released by magnetic fields and energy . Galaxies in the universe, that is, the quality of this release tiny particles of high-speed run to the far into the material by the formation of energy. The quality of the material universe, that is, the quality of tiny particles to smaller particles. 2. Conclusion language So Einstein do not think there is a certain density; structure; the quality of the particle, the particle level of quality is endless, with different densities of particles and structure of substances (particles), high and low speed of the formation of high and low quality of the material energy. On scientific cutting-edge issues, please consider this research, a lot of technological breakthroughs in natural science questions need to find answers from this article, I just love scientific principles, what is the exchange of views with me.

In my very unprofessional opinion, it seems to me that planting trees and halting deforstation of virgin forests would solve multiple problems. Not only would they greatly decrease the CO2 content in the atmosphere, but it would drastically decelerate desertification, restore the water table in deforested areas, and restore endangered ecosystems.

I think that we should stop using money currency and switch to a network( separate from the internet) of electronic debits and credits. This way crime can become completely preventable in a society that used this system. Fraud could not exist because of the system would be somewhat autonomous. We can have some sort of fingerprint ID which is how your account is charged and also how you are paid by your employer. We could have people who apply for business licenses to have a fingerprint ID scanner coupled with an ID card scan to ensure proper identity. When i say crime i mean illegal trades like drug trafficking. If we are not using cash it would be difficult and less economical for people to deal drugs because their business scanning system would show accounting errors or some strangely high priced items. Tax evasion would not exist either because all income is Automatically reported. It is a little bit of a fantastical idea but maybe something of the sort could help economic regulation.

Dear Sir, During my M.Sc. in Environmental Technology, I was given a class-assignment to tackle a global environmental problem in an innovative way. I chose “Rise of CO2 in the Air” because I had something to say on this. I wrote a plan which was low tech, can easily put into practice and where the whole world can come to play. The plan opens a new dimension to carbon trade for businesses, also the World. The outline was as this- Fast-growing trees assimilate CO2 out of air fast. We need to harvest these trees for their fast growing period in selected areas around the world. The harvest (dry hard wood is >70% carbon? And very slow degrading?) will be put away into caves, empty mines and faults- thus putting away atmospheric CO2 safely and cheaply for a very long time. After all, thousands of years old similar fossilized trees we use (oil, coal and gas) cause air CO2 to rise. Why not put back some? A Chinese saying is “Catastrophe = Opportunity”. Could we not witness the CO2 rise as an opportunity to store some energized Carbon (similar to currency?) for future use? Businesses may choose to grow & bury calculated numbers of trees each year to compensate for their extra carbon emission need. This plan will help developing countries come to terms with the world’s Carbon Trade agreement where they can even keep the harvest for themselves. This act means no offense to tree-lovers, forest-lovers or nature lovers. Only newly grown, purposefully, commercially harvested trees will be used, leaving natural forests alone. Scientists will calculate the numbers of trees required each year and decide types of trees to harvest for total sustainability (go bananas! ..may start experimenting with water hyacinth!). Desperate time calls for desperate measures! I know this is not ‘The’ solution, but as an Environmental Technologist I believe it has the signature of being a substantial part of it.

As an Army Officer who transported material across the world, I saw what modern transportation has done to rapid movement of large items. Instead of pipelines, dams, and reservoirs that have large environmental impacts, why not use the modular technology in conjunction with trains to move water from areas that are flooded or potentially flooded. A 60 car train should transport about 4.5 million gallons of water. The technology to pump water is there and used regularly. GE has hybrid train engines and with some additional electricity (solar panels etc), the engine could run hydrogen and electricity while powering the pumps for the water. Modular tanks are already produced or current sea/land vans could be lined to carry water. Currently there at least 40,000 unused rail cars. Multiple ways to link systems but it is a way to remove water before it damages and provide water to areas that need it using excess capacity or a specific set up.

I would just like to inform those that might be interested that my ideas for food safety would be to tell us where exactly the food was grown, and not where it was shipped from. Remember the strawberries a few years ago sickened several grade school kids and we were told they were shipped from California---but they were grown in Mexico. I have instructed my family, "We buy nothing from Mexico, period!!". Our Vice President said in an article in the USATODAY paper yesterday, said several things about how we should operate to make our food safer but never mentioned about where the food is grown, not shipped from!!!!!!!!!!!!!! Now, on another topic. In todays issue of the same paper they show a man telling us how much he liked his little electric car, and I have an idea about this! If you have an accident and bang up a fender or another panel somewhere, we should take a page out of the Nascar book and make our frames much stronger than we do today, then cover them with plastic fenders and panels that we should be able to buy from our 5 & dime store on the corner, or our parts store who handles things of this nature, Anywhere where there is competition to hold the price down. Our owners of these Nascars should be able to inform the makers of these panels where to get the best deals!! Can you see where these things could put people back to work, both in the plastics business and the installation and the selling of the part??? I don't know why we are stalling on these subjects!!!!

"I think the biggest engineering challenge is to have the profession recognised at its true worth to society. " 

I think the biggest engineering challenge is to have the profession recognised at its true worth to society. There are a few countries, such as Germany, Japan and parts of the USA, where engineering is revered as a qualification, and the profession flourishes in spite of many headwinds. In other societies in the developed world engineering is paradoxically seen as a basic skill, not worhty of recognition in status or reward. The paradox lies in the fact that the education system in these societies has been evolved to avoid the hard subject matter that is a prerequisite to any engineering qualification. Societies that recognise the potential of engineering as a profession, and appropriately reward its achievers, will contribute most in the discovery and development of solutions to the specific problems that your website seeks to prompt. I believe that the effort in this direction over the next decades will increasingly eminate from the east, which is a logical consequence of the fact that such a high proportion of the region's Kindergarden parents understand and pass on the importance of education, especially in the mathematical and science arenas. This aspect of glabalisation is one of the most positive I can imagine.

Solar Highways: Although solar fotovoltaic cells are a still less profitable way to obtain electric energy when compared with fosil energies, there's no doubt that they are an absolute trend for next decades and that this source of energy will be key for next generations' survival. In that particular sence, I think it could be a good idea to start exploiting right now the possibility to join in the same frame the construction of highways with the construction of solar centrals. A highway can easily support at its sides (and in the middle zone sometimes) a frame of solar fotovoltaic panels elevated for example 4 or 5 meters from the soil and with the possibility to rotate according to the sun position. This already well known structures could be replicated in theory across all the highway of any sunny zone of any country in the world. The idea is to take advantage on the fact that a highway is a sunk cost with a permanent impact and this impact can be additionally used to support another sunk cost with another permanent impact. Possibily, there could also be construction savings. Furthermore, it would be easier at the begining to attract investors for a solar central if it is part of a surelly profitable toll communication way, than otherwise. Business could be made for example with a partnership between an energy company and a highway company. The main point of this idea is that this way the presence of fotovoltaic solar energy arround the globe could be boosted just because there's an intense need to built or renewal highways everywhere, specially in emerging economies.

"Efforts to create photosynthesis artificially should certainly rank with sequestration of carbon dioxide as a challenge." 

1. I have serious doubts that sequestration of carbon dioxide will pass a cost-benefit test. Nature deals with it by using photo-synthesis to free the oxygen and use the carbon for building plant material. Effort to create photosynthesis artificially should certainly rank with sequestration of carbon dioxide as a challenge. It would be a lot easier to bury the resulting solid material. 2. If hydrogen is used as an energy-storage medium, the next question is whether it would more effective to ship the hydrogen to points of use, or to use it with fixed-base fuel cells at the point of creation and to transmit the resulting electricity to the points of use. I doubt that hydrogen and fuel cells in electric cars will prevail, so I bet on the second option. 3. Unspoken in the very meaningful challenge report is that population control lies at the heart of many of the problems addressed. The application of engineering to the reproductive process is certainly the equal of possible engineering actions to other biological processes. The fact that there are religious and other sociological barriers to the application of any results of such research and development should not prevent the search for better methods for dealing with this issue.

There remains humanity's unflagging acceptance of the quasi-engineering challenge, that suggests Mother Earth is incapable of satisfying each and every need of her beloved inhabitants. Dismantling this roadblock will involve a paradigmatic shift, not unlike any other technology application, requiring techniques of behavior engineering, currently in vogue. The overarching belief in scarcity undermines innovation by virtue of its unquestioned acceptance in human reasoning. There is a fantastic abundance of electrical energy pervading our Solar System in the form of electric ring currents. Our challenge is therefore, to activate, arouse and awaken the bountiful creativity long repressed in the human mind. Once that is accomplished, it will become obvious that scarcity has always been the mere figment of the imagination.

Please consider adding another Grand Challenge focused on complex adaptive systems. A few thoughts regarding a complex adaptive system grand challenge: This framework was influenced from work underway at the Boeing Company and the book "Complex Adaptive Systems" (Miller-Page). Research questions to consider: Study Industry-Academia and Governments as complex adaptive system: What is it that enables the their system to sustain productivity aggregate patterns through technological. For example in the aerospace industry, advanced material and product lifecycle management and global business partnerships i.e., distributed  global business shared risk-shared value investment model?  How robust are these heterogeneous social system? What is the capacity for dynamic adaptation? What policies and procedures enable adaptation, how do they propagate through the social network?  What is the effect of internal  external policy decisions, technology and global pressures change? How do these decisions support the goal oriented behaviors of social agents? (Contagion phenomena)  What computational models can we employ to better understand the Boeing Innovation culture, as a complex adaptive system?  What are the commonalities among adaptive agents (leadership, fellowship and extended workforce)? Can we distill these behaviors into prototypical adaptive behaviors; can we leverage this insight to shift lifelong learning strategies? Can we identify the level of sophistication and enabling conditions?  Social Niche Construction: the new business model fundamentally altered the internal agent behavior through exposure to global external agents and cultures. Can we model this new operational mode and understand how to leverage the combined intellectual capital generated from this diverse perspective? Social worlds: This new model presents a opportunity to shape influence global behaviors by shifting the balance of local and regional control. How is this accomplished by agents within this global environment? How does this decentralized  centralized balance occur, how does this impact agent behavior i.e., heuristic business modeling for the benefit of the collective system goals?  Social agents receive or acquire knowledge; the information is leveraged against a schema, processes and acted on. Within the social network, how do agents access information, what is the level of fidelity, how do they direct their acts toward optimizing the solution space?

"Several of the remaining challenges can be solved if we have access to clean power. " 

In my mind, the greatest challenge is the generation of cheap, plentiful power. Several of the remaining challenges can be solved if we have access to clean power. This can come from many sources but ultimately all power on earth originated with the nuclear fusion reactor we call the Sun. We should look to solar and nuclear power as the primary sources for this clean energy. Engineers and scientists should also take a larger part in developing public policy.

Consider placing sol-stationary solar collectors in series between the earth and venus. The collectors would be convex mirrors (~3 ft. in diameter) teathered to reflective foil parabolic parachutes (~500 ft in diameter) with a hole in their middle. The concave side of the foil would face the sun, reflect sunlight to the convex mirror which would then focus it earthward through the hole in the foil. Dozen of these assemblies could be placed in a line so that the final beam could be dozens of megawatts of thermal energy. Each assembly would be held into place by the balancing of the solar wind force pushing the assembly spaceward against the gravitational force on the mirror. The nearer an assembly is to the sun, the lighter the mirror and or larger the foil. It is this opposing force dynamic that would allow an object that is closer to the sun to maintain the same rate of revolutioin around the sun as the farther away earth. These concentrated beams of light could be used to protect crops from occassional freezes, melt ice for fresh water, make battle zones temporarily uninhabitable, optimize climate (like evaporate sea water channeled to death valley so that Utah, Nevada have higher air humidity), run power stations on earth, and possibly disrupt hurricanes. Since the assembies could be 'sailed' by feathering the foil 'sail' they would only consist of a mirror, a small solar collector to run servos that tug on specific wires of the 'parachute'. In theory, mass produced assembly could be produced for a pitance. One last thought is the climate effect. Blocking sunlight and then channeling it for power reduces heat input to the earth as well as reducing heat retention.

"Make solar energy affordable" is inadequate; transmission and annual-scale firming storage are necessary for "solar" and other large-scale stranded renewables. Electricity transmission provides no affordable annual-scale storage. We find that gaseous hydrogen (GH2) and anhydrous ammonia (NH3), gathered and transmitted and distributed via underground pipelines as C-free fuels, firmed in solution-mined salt caverns (for GH2) and surface liquid "atmospheric" tanks, would allow us to run the world on renewables. See our papers, posters, and conference presentations at www.leightyfoundation.org /earth.php We must think energy systems, not sources.

The only way engineering can advance is if we focus on what is actually possible within the realm of what we already know, I have read alot of the previous comments and reading some of them I actually lost a little bit of hope for humanity. Just a couple that stood out in my mind, Transmitting energy wirelessly is physically possible, but you cannot control it's direction, it is well known that electricity follows the path of least resistance, in an atmosphere resistance is homogenous, this means that the energy goes in all directions losing more and more energy to both the fact that it is spreading in a spherical manner, and the extremely high resistance of air. basically what I am saying is that you can transmit electricity through air, but it would be amazingly inefficient and would probably kill everyone in the room. the other proposition that I remember is the idea that we could make bacteria that consume CO2 and produce water, I would recommend a basic chemistry class to this idea's author, Carbon and oxygen do not make water. Hydrogen and oxygen do, so in order for these bacteria to produce water they would need to be supplied with hydrogen and probably produce pure carbon as a byproduct, not a terrible idea altogether until you consider the energy that has to go into the production of hydrogen it ends up being a wash, with today's energy costs its just not economical to use hydrogen fed bacteria for capturing carbon. but at least these two authors gave an honest effort, albeit a very idealistic attempt, they are still far superior to the single sentence of one "d.venkateswarlu" from india, this kind of pessimism is not constructive in any way, and if you want to continue making statements like that I suggest you change fields, literature perhaps. Overall i like the comments that are on this site, it shows that people, especially young people still have ideas, and still want to change the world for the better. With just a little bit of guidance these ideas could be pointed in the right direction and actually do some real good, for example, if you want to transmit energy efficiently, look into high temperature superconductors, if you want to work with bacteria to improve the world, look into genetics to make bacteria that produce new pharmaceuticals, I hope that my remarks on the two previous ideas did not discourage their authors, I only want to provide some of my previously mentioned guidance. and thats the end of my rant :P

Engineering is not always necessary to solve the perils created by human kind itself. A general approach may bring a drastic change. I, being a student of chemical engineering, strongly believe that, small changes like avoiding packaged drinking water(to prevent exposure of plastics to environment) may be considered one of the step. Figure this out, a used plastic pouch has an approximate area of 0.005 sq.m only. Imagine that a small location of population around 100000 causes an exposure of around 5000 used bags per day. The area for heat transfer with atmosphere available is thus 25sq.m. Summing up for a city of population around 500000 and considering the average consumption of 200000, the area is 10000 sq. m. WOW! almost equal to 2 football grounds. These statistics are for a single day and a single location. Now consider usage in whole world, and u get 1000s of football ground exposed to amosphere directly to exchange heat. a temperature difference of 5 degrees celcius and avg conductivity of 2 will give 100000 watts of heat per day. Now u can imagine the HUGE effect of a small change.

One important way that Engineering can improve the world, is to have an epistemological sense of itself, i.e. to know the bounds of problems it is equipped to potentially solve. Some problems are better addressed through social science, focusing on innovative applications of existing technology. For instance, virtual reality is listed as one of the 14 challenges, however online social networking applications such as Facebook, which are certainly some of the most compelling forms of "virtual reality" existing today, are not mentioned. Technology is a partial solution. When Engineers work in tandem with social scientists and social innovators, better solutions emerge.

If food habits can be changed there is enough water for providing safe drinking water to all the population in the world. For instance one kg. of paddy consumes about 4000 litres of water.

We need statesman here not the run of the mill politicians whose agenda most of the times is for 3-5 year time span.

"...governments of first-world countries should start making new desalination plants and distribute the water to third world countries..." 

I was thinking to give access to clean water throughout the world is this: governments of first-world countries should start making new desalination plants and distribute the water to third world countries and use the water to replenish reservoirs with the water [the reason why I think it would be best to replenish reservoirs rather than just give people the water is because the reservoirs are where the water evaporates into the atmosphere and begins the water cycle which would be better because it would feed crops better, gives nature some of the water for plants and animals, and distribute the water much better.]  I'd also a have people make sure that theres only a certain amount of water each person or farm would get; making it much more sustainable. last but certainly not least, I start making a wide range of water plants that recycle the sewage water, filter and clean it, and redistrubute the water [they already do have a plant located in orange county, California that recycles sewage water but It would be good if we started making lots of these plants.] if we did all these things, we would save millions [if not billions because a third of our world lacks clean water.] of life's, and stop world hunger.

Engineering, reviewing current trends, will lead to more efficient technologies. These technologies will not be enitirely new ones, but improved versions of the ones we use today. I conducted a research lately on the future of aeronautics. I designed a plane for the aviation needs of 2058. During the research I noticed that current technical efforts were directed on improving current technologies rather than making new ones. For example, the research on the propulsion systems is meant not to come up with an engine with an entirely new mechanism, but instead to understand the operating principles better through computational engineering and then only to 'modify' current designs. By studying new concepts like the Boundary Layer Ingestion (BLI), engineers are working to change the current propulsion sytems by varing nozzle/intake geometry, engine placement, and bypass ratios, so that the utilize BLI efficiently. The results are better engine configurations which can be validated without largescale design revisions. This means that technology can be improved significantly to meet changing demands with minimum wastage of effort and, most importantly, money. Engineering in the coming years will improve existing technologies with moderate capital investments, benefiting the developing economies in particular.

Assume, for a moment, that we found the perfect, everlasting, abundant, and totally non-polluting source of energy. Assume also that this energy was freely available, compact, portable, very cheap, and simple enough for anyone to harness with simple/cheap off-the-shelf equipment. Also assume this energy would be available to all, from the poorest-of-poor to the richest-of-rich, as it is neither patentable nor could anyone own it's source, as it is everywhere. Assume also that this energy would be capable of energizing all of our current machines of the world many times over into the future, ad infintum...

Now, this hypothetical 'perfect energy' may one day become a reality. But the pertinent questions we must ask ourselves are these.... What would we DO with this free and abundant energy, if we were to have it NOW? Likewise, what would 'they' do with it? What are we doing NOW with our CURRENT cheap energy? (Oil is about a dime per cup, and a couple gallons of oil does the work of one man-year of labor.) Again, what are 'they' doing with it? Extrapolate, if you will, from our current energy needs and wants, on into our future needs and wants....Include our children's needs and wants, and their children, and on and on. Include all the nations of the world. Include 'them'... Would we not overpopulate, overpollute, and overextract everything of value within this once precious Earth? If one were inclined to say "No", then consider how one could prevent someone else from saying "Hmmm...Yes, why not? (We'll just lobby!)". Are we/they not destroying our planet now with cheap oil? Also consider the 'darker-side' uses of this perfect energy, as in the utilization of this cheap, compact, and portable energy as a 'not-so-friendly' gesture of general disagreement. Again, would any Earth-Life survive? Do we really need what we so desparately want? Is it for the good of FUTURE Mankind, i.e, the child, and his Earth-home, that we find this energy? Judging by our current uses of energy, some would think not.

"Our society today demands more accurate modeling of our world..." 

Throughout civilization's advancement, modeling of what is 'to be' has allowed engineers through simulation to experiment and optimize solutions that have advanced modern society. Our society today demands more accurate modeling of our world so that better decisions on how things are to be and how these things will behave can be explored. Advances in modeling of electrical infrastructure in particular are critically important, as is the lean management approach to the data and information required to make better decision on this decaying infrastructure. The application of Machine Learning in making better decisions on predicting potential issues with underground infrastructure is one such example of better math to enable better decisions. Models of infrastructure using version 31 of old Fortran computer software models will not allow us to make the advancements we need to migrate to the electric economy that can enable the significant use of renewables and demand side management.

I read somewhere that the possibility of immortality was actually possible....really? I guess I wouldn't be too surprised, with all of this new and amazing technology, however, when and how would you go about this? I've heard about transfering brains into computers (kind of like the matrix...seriously!), cryonics (or something like that), and a way to manipulate genes in order to stop aging in the body, or at least prolong youth untiil some kind of replacement or transfer can occur. I also understand that this process could probably take place within the year of 2050 -2080.....interesting stuff to ponder on :)

A large volume of water is used for power plants as a heat exchange medium. Some experimental designs for a new generation of nuclear power plants use Helium as a heat exchange medium. I was thinking that water could be saved for drinking and agriculture by switching power plants to use helium gas as a heat exchange medium. It has a much lower boiling point than water so I was questioning if it would be even better at generating electricity.

With respect to some the comments on this page, it's easy to jump to solutions instead of identifying the challenges. A lot of the challenges that were mentioned by the committee are really a subset of a larger challenge: an abundant and sustainable energy source.

I recently read an article about ozone pollution. There were so many discussions about environmental limits. If I remember my basic chemistry, ozone is 3 oxygen atoms bonded. It occurred to me to develop a [catalytic converter] of sorts for smoke stacks. My theory was to have a device to break up the ozone molecule and let it recombine as oxygen. I thought that an electrically charged plate (solar powered, wind backup) would satisfy the valence shell electron and break up the ozone, then send it through a gradient to allow the oxygen ions to recombine.

Engineering community, The article "Introduction for grand challenges for Engineering" was well written. Onother couple of topics left out. Harnising the hydrodgen fuel cell cheaply. Some company's have claimed they can cheaply crack water (into hydrodgen and oxygen) by using nanotechnology. The most important one left out is an American issue all to itself. The U.S. is failing to produce large number's of engineer's which will leave a major talent drain in the U.S. For the U.S. to reclaim/maintain it's technology and innovation, bringing Engineering back to the forefront in the U.S. must happen or we will lose (our losing) our hold on being a technology leader. This change must occur fast. China is pumping out 650,000 engineers per/year form college and the U.S. is only bringing 75,000. Accoring to world ranking, the U.S. colleges are rated 17th in the world, wheras, a half a century ago, we were 1, or 2 in getting a quality education. How do we convince our Government/kids/parents, that engineering and science are the needed fields to be in. The field that will allow the country to pull out of the slippery slope the U.S.is currently on? History, has told us time and time again, that technology will always be a major layer as to how well a country prospers or suffers. How do we (as U.S. citizen's) make the change of the failing system and get innovation and engineering back to the forefront? Sincerely, Mark Webster Kokomo, IN

I have two suggestions for the scientists and engineers: #1 - If you can simply design wings for the human being so that we can fly like birds. If it can be done, we don't need to worry about building million miles of road networks, we don't need to live in congested cities and no need to worry about CO2. Most of todays problems will be solved. This idea might be little too far but hope this can be done in the near future. #2 - If we can design human body through genetic engineering (by inserting plant genes) to have chloropyll in the body which can perform photosynthesis in presence of sun light like any plants do. People won't suffer from hunger, malnutrition, food safety, etc. I hope these two are not that difficult achieve in the near future. Best,

Engineering has to improve statistic methods. Most decisions are made based on statistics that do not represent opinions or characteristics of man or any other research subjects reliable. From this it follows that we have to improve the engineering of statistics. The (especially in Germany) popular idiom "I only believe in statistics that I doctored myself." demonstrates the current situation. decisions are like steps upstairs, it's dangerous when the bottom of these stairs is not firm and reliable. The improvement of engineering of the statistic methods has to go along with all the other challenges.

I have gone through the Grand challenges. I belive before creating a new era or innovation better to look backwards and bridge these new challenges where it can fullfill the earlier engineering developments. In addition every invention has two sides such as Bad and Good, the magnitude of the direction is decided by the mob/decesion maker. So this is the time for challengeing the past innovations rather than finding new challenges. I also belive the challenges posted are shortlisted from human evidencing disasters earlier times. I belive the biggest challenge is to the engineer life cycle of a citizen.

GRAND CHALLENGES What are the grand challenges for engineers? Engineers, today and in the future, need to fully examine our design & construction processes to determine the impacts (both positive and negative on all life forms) for the next 7 generations as a guiding principle (source: the Iroquois Confederation). Principle Declarations I. We must reclaim our humanity through creatively imagining the future with everyone (every being on this planet is a stakeholder -- not only our clients, employers, and local ecosystems and local human communities). II. We must change our engineering foundations from Newtonian/Cartesian thinking (mechanical-based, disconnected, separate, reductionist analytical theories and laws) to integrative and complementary, fluid, circular, holistic living systems-based, connected, conceptual theories and laws. We can not change the world for the better until we change the way that we view the world. III. We must choose peace and not war. We must decide to use our intelligence to create a peaceful, fair, just, and humane world. We have participated way too long in Wars where we systematically kill ourselves, therefore we must begin the process of healing and saving ourselves. We must support and engage in research efforts that enhance everyone's humanity, imagination, creativity, and overall well-being. IV. We must support ethics by not condoning corruption and other unethical behaviors in our business dealings, pursuits, research, etc. V. We must examine our design and construction processes through life cycle ecological & temporal synthesis (geologic time constraints, internal and external costs, ecosystem health impact, human health impact, overall global impacts - biogeophysicochemical cycles, etc.) rather than life cycle analysis. VI. We must develop frameworks similar to the Cradle to Cradle framework created by the MBDC. VII. We must develop energy effective rather than energy efficient products (source: MBDC). VIII. We must work with the general public better because solving the world's problems and avoiding creating future problems requires working in true interdisciplinary teams. IX. We must continue research efforts in the field of biomimicry. X. We must uphold ecological health systems [ecosystem health & human health (biological, economic, emotional, social, spiritual) in our top lines rather than our bottom lines (source for triple top lines: MBDC).

Engineering has a great opportunity to not only advance the cutting edge of advanced technology, but more importantly to find ways to ecenomically bridge the divide between the richest of nations and the poorest. The great divide is certainly an engine for conflict which will continue to drain rich nation's wealth on national defense. An investment in the future will find ways to reduce the wealth gap through the building of infrastructure in the poorest of nations. Through technology improvements that can reduce the cost of current technology and a forward thinking policy to fight the root conflict the world can be made much better via engieering and technology.

First and foremost I'd like to express my thanks for at least having such a forum available where people can express themselves in regards to these issue. now I'd like to take this opportunity to say a few things about the issues brought to the table here. What is the purpose of this site? to inform the public about what could be done in the future? what about today. The time is now!! and it's all the time we get. no matter how much planning or debating or wishing is done, we are still wasting the only time we will ever have to do the things we're not doing right now. stop the crying over spilt milk and let's get off our butts and do something. I am so tired of hearing about the next big breakthrough in whatever field we're talking about. I am 100% positive that if we wanted solar energy to be the main source of electricity for our urban centers it can be done with nothing more than will power, which costs the taxpayers nothing. efficency is the tag line for solar energy. we need more effiiciency. how efficient is the destruction of the ozone layer? let's just start using it and worry about efficiency as we grow with the technology. sound evolutionary to you. natural maybe. The promise of making a killing in the fiels of solar energy is the only thing holding it back from benefitting all of us right now. money is the greatest excuse those who have it and control it can use to deter those who don't have it from achieving their goals. What it takes to get things done isn't monetary in nature. human beings survived for a long time without money and seemed to get things done in ways we will never truly know or understand. I'm not saying anything about getting rid of money or using a barter system, but human beings make money from paper made from trees. the importance comes from that which we put on it and it has gotten to a point where we have fooled ourselves into thinking money controls us, therefore those who control the money control us. well I for one am not sacrificing my life so people can have gold toilets, SUV's and flatscreen tv's. Food and water maybe! the basics. this is where we need to go. we need to supply the need not the demand. If I demand 40 virgins and all the beer I can drink. do I have to go bomb a building to get it in my next life? or do I just sell you oil to burn and call it a "prophet"-able day. educating the young is a problem only because the young will conquer the old and create a new system of thier own which the older generation will resent them for having when they did not and could not create themselves. the jealous side of human nature. so until the old school thinkers can benefit equally from any new system (monetarily as this is the only thing woth having to them) more war and strife are looming to stop any new system from emerging. I am also 100% positive that on the day I was born, when mankind was sending it's first explorers to set foot on another body in the universe (the Moon, JULY 16, 1969) the money spent to do so was alot more than it would cost today. but of course inflation / greed has increased substantially since then, so the costs of even repeating tasks that have already been accomplished would cost more. this is not how nature works but this is how society as we have allowed it to become works. nature is our only teacher but again the experts know more and know better. not just in the field of space exploration but in every walk of life? The mindset of the people in charge is that they deserve to be in charge and make decisions for the rest of us who can't make decisions for ourselves. well if asked I'm pretty sure I can make any decision I need to make given the proper information. this is the next point i'd like to make. information is the root of evil not money. those with the information always use it to better themselves which naturally makes it worse for others somewhere. simple math to illustrate. if you have 50 apples in your bag, that means 50 people can't have 1 apple each. is that simple enough, can george bushites understand that kind of simple and true logic? there will be no true democracy until the commmon man can have his own voice heard instead of an elected official whose voice is bought and paid for. this is the future of the communication network evolving out of the internet. a forum where true democracy can actually raise it's head and proudly proclaim to be the voice of the people by the people themselves. No small closed off groups to manipulate us anymore. voting will be real and meaningful as it has never been in the past. We need to change our ways of thinking about life, about society/civilization and about the future. we leave a splintered and corrupt legasy of abuse to the planet that spawned us all. We have already condemned our future generations to a life of slavery just to undo the damage we've done. yet all we can do is praise ourselves for the technology we have and the lifestyles we lead. we are the most useless and worthless society yet to emerge due to our lack of connection to the real world we live in and what's worse is we're destroying it. when was the last time you said no to buying gas which you know causes wars and pollutes the atmosphere? yeah I thought so. I don't own a car and won't until they come fully electric. you think this is a long way off but it's actually a long time gone by because electric cars have been around since before the combustion engine. those in control felt it was better for you to have gas guzzling cars instead. for an answer to the question why, just look at the "president" a dumb as a stump cowboy who thinks because he has money and power (gained from your consumption of gas) that it is somehow his right to make decisions for the rest of us. this guy wasn't even elected to the office and you're still allowing him to rule you like julius ceaser. is this guys word the best that you can offer the world? if so the US is headed for a major fall on the order of the Egyptians, romans, and especially the Neanderthals. Economies can't survive being based on commodities which come, go and run out. ecomonies need to be based on those who are affected by them meaning people. nothing can run without people. people buy and sell. people consume goods and services. people are the most underrated and under used commodity out there. we all need to eat, we all need to drink, we all need a roof over our heads. and we all will do whatever we have to do to get these things whether it's work 9-5, rob, cheat, steal, or kill. I say base the ecomony of the world on the simple principles of feed and house, and let the rest sort itself out. We have people better suited to run the free world than george bush and the like. or do we just want to let the wild west riegn forever and have things sorted out in a manner man can only acheive with a handful of bullets. If that's the future we're going to allow, I'd rather go back to my birthday 38 years ago when man had at least a hope of better things to come. in not so short, ACTION NOW is what we need to focus on, not questions like "What are the engineering challenges we need to focus on?" don't put off until tomoorow what you can do today because tomorrow isn't guarrenteed to any of us. and I mean that literally. we will always be able to ask questions of what to do but let's get something done now that we engineer to be "UPGRADABLE" in the future. We've been asking the wrong questions for far too long already and these questions are not going to go away even after we find the answers, a whole new set of questions must arise. this is change, and it rules the universe not your local goverment no matter what they try to tell you. this is where your fight is, not fighting change itself but fight for the changes you know to be right, are you up to that challenge?

Dear Fellow Engineers, We have seen so may revolutions including Industrial, Automobiles,Information Technology ,Space and what not. We have missed to solve the problem of shortage of safe & good water. It applies to Drinking as well as for Agriculture . We have forgotten that Nature [ or say GOD ] has given us on this earth more of WATER only. That too with a safe pollutant resistant as Common Salt .Even if it is salty it is only water which can be desalinated. The question is how to economically desalinate this? When the whole focus is on it, solutions can be easily found. We can find ways to get Good Water and Hydrogen from sea water to feed all the populations right from Plants , Animals and Humans. May be ,hydrogen as a bye product will be the best replacement for the Petroleum. The whole world is facing inflation due to the so called 'PETRO - GOLD ' pricing . Let the best of our Engineering Brains spend their energy with the support of the International Donors / Sponsors to break new grounds There is a famous quote from an Indian Swamiji as follows: 'THE PROBLEM IS YOU THE SOLUTION IS YOU ONLY' Let us jointly solve this problem. .The problem is only SALT. Desalination at an economical process. I am confident that the Engineers and Scientists who made Mr Neel Armstrong to land on the Moon and return safely will be able to solve it - given the right direction and resources. True to his words 'LET US GET A GREAT LEAP FOR MANKIND BY TAKING THE ABOVE SMALL STEPS' Social Medicine Scientists and Agricultural Scientists will agree that better drinking water will bring in better healthy individuals and better plants/crops. And environmentalists should take care of the GREEN OCEAN in this endeavour. WISHING THE BEST WE ENGINEERS MAKE THE WORLD

One challenge not mentioned in the list is that of finding a way to reduce the human population of the planet, and maintain it at a low, sustainable level, preferably without resorting to nuclear war or a global fatal disease epidemic. Our other scientific and engineering challenges can ultimately be traced back to the fact that there are simply too many people trying to thrive on a limitted amount of resources. Global education of people about science and the consequences of over population seems the most effective method of achieving this goal. If huge amounts of money and diplomatic effort could be spent on the education of the world's population about basic biology, chemistry, ecology, geology, and all aspects of how our planet and its inhabitants funciton, then people would be in a better position to make political and lifestyle decisions.

The greatest problem we face is the ongoing human population explosion. This core problem is a major contributing factor to many other serious problems, such as running out of water, deforestation, desertification, collapse of fishery populations, running out of oil, pollution in many forms, climate change, etc. There are simply too many of us humans for this planet to support. Therefore, the most serious challenge we face, in my opinion, is to find humane ways to regulate, control, and reduce the human population.

Achieving the goal of sustainable development is indeed one of the greatest challenges of the 21st century. If industrialization and economic development is not based on the premise of sustainable development that is in harmony with nature’s carrying capacity (supportive and assimilative capacity), human civilization cannot realize the goal of eradicating poverty and improving the living standards of the majority of its population. The present open ended economy which is driven by unsustainable pattern of consumtion must be replaced with ecological economy wherein the use of natural resources must not exceed the rate of their regeneration. Ecological economy would help to preserve the ecological integrity of the earth system and produce waste only at the rate at which it could be assimilated by the nature. All our present and future developmental goals are to be set on the premise of symbiotic relationship between consumer human race and producer natural systems so that dynamic equilibrium is always maintained between them. The very goal of sustainable development offer multitude of great challenges and opportunities for engineers and scientists, those challenges may be broadly categorized as follows. Materials Materials we formulate and design must have closed loop, either they should be recyclable or be safely assimilated by nature at the end of their life cycle. Production and Process Engineering Zero waste and zero emission Energy I vote for the combination of wind, solar, tidal and bio-waste energy. Until problem of nuclear waste is solved, or nuclear energy is based on closed loop cycle with zero waste it is not a viable solution for energy problem Engineers must design affordable and viable energy generating systems (wind, solar and bio-waste) which can be installed and maintained by individuals at house-hold level. Water and Sanitation Desalination plants driven by tidal and wind energy Affordable biological wastewater treatment plants which can be installed and maintained by individuals at house-hold level Aero-toilets, can natural air be harnessed for flushing instead of water, a great challenge for engineers. Sanitary engineers and compressed air technologists may have to work together Food and Agriculture Genetically engineered crops which use atmospheric moisture for their growth Can we design plants which make use hydrogen and oxygen available in atmosphere and produce water for themselves Can we design a single crop which can deliver all nutritional requirements? Shelter A simple shelter kit which is affordable by masses, can be bought across the counter and be assembled by individuals. Such shelter kits should fulfill the basic functional requirement such as protection from natural forces and man made hazards, privacy and durability. Health Replacing and/or repairing defective parts of brain If any disease is traced to particular genes, doctors simply should be able to replace the defective gene and cure the patient. Indeed a great challenge to genetic engineers and doctors. Elimination of all known inherited or genetic diseases would be a wonderful gift to humanity. Drugs with zero-side effect Build virtual hospital which works round the clock ( 24x7x365 ) and can reach the masses. A patient from any geographical corner of the world simply should be able to reach this hospital through local machine and interact with doctor. Hardware and software required to measure basic health parameters (like blood pressure, pulse rate, temperature etc.) should be part of the local personal computer. This basic data should be delivered real-time to the virtual hospital. At least regional virtual hospitals which can be connected to all villages in the region would have revolutionary impact on rural health system in developing countries. It is great opportunity and challenge for computer and information technology engineers Transportation Transport sector is the enemy of climate scientists. Again a big challenge and opportunity for all those concerned engineers in this sector. Carbon footprint of a typical car is about 250 grams /km, whereas it is 3 grams/km for walking and cycling, so walking is almost 80 percent more efficient in terms of carbon footprint. Human beings are akin to bio-reactors and produce energy very efficiently. Comparative analysis of IC engines and these bio-reactors make very interesting study. We need to understand in grater detail the principles behind the energy production and energy management system of this organic automobile (human beings), and explore the possibility of adopting them in cars and other automobiles. We climb, jump, jog, swim , think etc., I am sure energy requirement is different for these different activities, energy management system of human beings (even some animals) must be very sophisticated and efficient to manage these multi-tasks. If we include energy as constraint, then all these so called state-of-the-art automobiles, aircrafts, trains, ships and even many more gadgets suddenly looks primitive!!! Transport sector should be powered by air, water and sun; it is indeed a great challenge and a pre-requisite for SUSTAINABLE DEVELOPMENT.

Idea For Personalised Learning. In the information age everything is going to become digital or computerised. reading printed material should not be encouraged. yet there is tremendous use of computer printing as the information is always printed on paper for reading. the reason is habbit & less burdon on eyes. the purpose of digitisation i.e paperless office will never achieved. If we see the problem in different approach find that the person is reading means he is reading in his own voice which no one is hearing . so if the information he get in textual format if get in his own voice in audible format it would be very helpfull . so there should be development in technolgy which converts textual data in the persons own voice data. simce every person has different accent & pronounsation differ from country to country this technolgy will be very helpful.the student do not need to starin his eyes on comuter or thick books. his laptop or media player will be enough to carry the task. he would have feeling as if he is listening his own recorded voice. the tecnology sould be developed to break the recorded sound amplitudes with a program & would develop a code which will standardise it so that every sentance will be converted into the persons voice.

One of the important thing in urban infrastructure is mass transit.It reduces the polution cosiderably.The stress on mass transit is always high & it became the most usafe & unpleasent mode of travel. the infrastructure for mass transit should be improved to make it more attractive & enjoyable experience for the commuters. one of the method i would suggest is use of natural force- Gravity for mass transit. A sloping track can be built on the existing rail track like roller coster. the slope will cause the acceleration & speed up the car at the destination the slope will not maintain resulting stopping of the car. the bottom of a car has an air bag whose botton will mach with the slope resulting keeping the commuters of the car in horizaontal position. when the car approaches towards the destination the air bag will release the air resulting to make it horizontal agin near the destination.If the car wish to travel again next station it has to travel a negative slope. for this there should be two approchase eithe a vertical lift or using travelling belt which is moving continuously. the structure required for this arrangement will be high in air cosidering 20 meter high with slope of 1 degree.so for every 1 km there would be requirement of lift station of 20m high. the car used for this type of transport will be similer for roller coster with 4 occupants. this method should be studied in engineering asspect with improvements in design.

A Space Elevator is a mandatory requirement for human advancement. Regarding matters of objective environmental research, simple scientific methodology implies that we should be collecting regular environmental data on non-terrestrial bodies, so that a reliable set of base data can be arrived at for analysing the environmental data of Earth. Humanity must explore our solar system, and especially our near neighbours like the Moon, Venus and Mars. This will not be economically viable, via contemporary rocketry, and the carbon load will be prohibitive. Although in it's first iteration a Space Elevator will be a serious scientific an financial undertaking, following versions will be much more accessible. The first 'proof of concept' of a Space Elevator must be built on the moon, where the one sixth gravity will make it immediately doable with contemporary materials and technology. Valuable experience will be collated and inexpensive access to the lunar surface will be made available. Once built a Space Elevator makes Low Earth Orbit launches trivially inexpensive, and real non-terrestrial scientific research in the grasp of even Post-Graduate students. http://en.wikipedia.org/w iki/Space_elevator

Sustainable living, also called a "full-world" mindset, is necessary as all the accessible places in the world either support life directly or indirectly. A reasonable and balanced approach to fulfiling life's necessities need be determined, established and maintained. I've offered a few ideas to folks for reducing the demands people make on the planet, without much sacrifice. For instance: 1. If all the appropriate roof tops in the USA, and wherever it is affordable , were to be used either for solar power generation, solar water heating or small wind power plants the need for new, large, centralized power generating plants (and the requisite distribution infrastructure) could be vastly reduced. Carbon Dioxide would also be reduced and folks would have the power needed for a modern, efficient-utilization, lifestyle without induced suffering or sacrifice. 2. If large scale electrolysis and fuel cells (possibly on a closed, or near-closed, cycle loop) were placed near water sources, along the routes of power distribution grids, then the fluctuations of solar and wind based electrical power generation might be smoothed out efficiently and effectively. 3. I've proposed to a few organizations that we team up to take on the American X Prize challenge of the 100 mpg auto. I believe that there are reasonable and relatively simple steps to that end that, for reasons that (I hope) have escaped me (because the ones I can imagine are seriously unflattering), have not been sufficiently pursued; if at all. There is much talk, in this election year, of energy independence. I feel that unless people are willing to make tremendous sacrifice that that goal is unattainable. However, sustainable energy utilization is possible with moderation and comparatively small changes in our way of living on planet Earth.

Develop carbon sequestration methods: This one is a dual use strategy, make bio fuel, and sequester CO2. http://www.youtube.com/wa tch?v=8hioZ7C6HLs It is the Vertigro System developed by Valcent fuels that uses certain high oil yield algae to turn sewer waste into bio fuel, and the remaining material can be used as fertilizer or sequestered underground possibly even in dry oil wells. The best part is the land used to grow the Algae can be desert, and thus not disrupt land used to grow food. One of the best places to get a virtual unlimited supply of high phosphate water is the Salton sea in the Sonora desert as discussed by Michael Briggs of UNH. http://www.unh.edu/p2/bio diesel/article_alge.html The vast majority of land in the Sonora Desert is unused. http://en.wikipedia.org/w iki/Sonora_desert

Ideas in regards to Fusion: On the hot fusion side Google is very familiar with the late Mr. Bussard's work: http://en.wikipedia.org/w iki/Bussard On the alternate fusion side : Bubble fusion shows the signature background effects and it works now, and costs much less than any other approach. http://en.wikipedia.org/w iki/Bubble_fusion Thou it gets a lot of grief from the big hot fusion people, Cold Fusion has produced excess heat, and background elements indicative of fusion.

There are so many things that need to be done. People need to start working together again like they used to in small communities, but now on a larger scale. There are too many people 'in power' that only look out for themselves. I'm sure many would agree that more and more we perceive the world as getting more greedy and more selfish. One of the most important things we need to work on is a world standardized education. An intelligent world is a better world. A lot of problems are caused by ignorance. Then we can focus on everything else: alternative energy, better infrastructure, etc.

Cars roof could be installed with inexpensive solar cells on top to charge a battery. When charged, this battery could be replaced in the gas station for a discharged new one and a tax payment discount would be obtained in the fuel . The batteries from the gas station could be used to charged a bigger one or a more efficient electricity supply mechanism. This process would hold forever in a quite cheap way if the batteries and solar cells were provided when buying a new car.

This post is just for the solar issue: The SEGs system in California works well now for large scale solar power. 354 Mega Watts out in the Mojave Desert. http://en.wikipedia.org/w iki/SEGS Solar Power Tower: From the article they need cheaper Heliostat methods and I think this could be achieved with one central sun tracker, and the panels controlled with cheap servos akin to those used on model RC cars. A cheaper tracker can be made via using 4 photo diodes split N-S-E-W by semi transparent vertical grid walls point up to the sky, and have the 4 photo diodes seek equalization, ie. track til they get equal light on all 4 diodes that separated by the 4 way vertical divider grid. photo diodes are very cheap and are on top of all the street lights in every major US city. http://en.wikipedia.org/w iki/Solar_power_tower For small scale solar for the mass nanosolar has very promising approach and just needs further research in its current area.

How can you have too many people? Too many mosquitos, cokroaches or rats yes, but too many people? That we are thriving as a species is a cause for celebration surely. Human beings are wonderful. We compose symphonies, write literature, design buildings and fly through space. Poverty is a consequence of failed and outdated politcal and economic systems and this obsession with numbers is misanthropic.

The grand challenges addressed are very realastic. To reduce global warming by means of reducing carbon di oxide, it needs to improve the quality of vehicle as well as the fuel. Public should use common public carrier instead of personal car. Conditions of the road in India are to be improved to reduce the co/co2 emmission. So let us educate public to reduce great burden on the Engineers in the 21st Century and so on.

I think I'd have voted with the majority to make solar power cheaper but I'm pretty sure this is already happening. REC is putting in a 1.5 GW manufacturing plant in Singapore and this should have the scale needed to make solar power cheaper than coal. The US is falling behind in solar power manufacturing and should try to do something about this but costs are going to go down dramatically if we do or if we don't. So, I voted for sequestration. But, I don't support sequestration of carbon dioxide. I think we need much better engineering than that. We need to sequester carbon in elemental form or as carbonate minerals. And, we need to do it from the atmosphere, not power plants. This, I think, is going to be the greatest engineering challenge of the next fifty years. We need to bring the concentation of carbon dioxide in the atmosphere down below 320 ppm from its current value of 385 ppm. So, we need to retrieve about half of the carbon we have put into the atmosphere since about 1965. The biosphere has soaked up the other half already. Revisioning engineering to be planetary and cooperative with the ecosystem seems to me to be about the only way a challenge of this magnitude can be met. Managing the nitrogen cycle is probably only an beginning for this.

Ocean algae is reportedly the major mechanism for removing CO2 from the atmosphere. Why not genetically engineer a salt water algae that increases its growth rates as the atmospheric CO2 concentration increases? Then, find an edible fish that eats this algae. Solves two problems: Global warming from high CO2 concentrations & food shortages.

Submit that until corruption of our rulers and barriers against social reality is dealt with, any further technological progress just adds weapons to the arsenals of tyrants and further enslaves people who must react. I am no Luddite, I am an engineer and innovator. The way engineers can help is by fighting the forces of ignorance and manipulation. The "rule of law" is a precisely defined law. It is the highest law of mankind, stated below: the suppression of forceful and fraudulent methods of goal seeking all are treated equally by the law. This means ALL, including king and judges absolute property rights This in turn is based on the fact that human behavior (the topic of law) is about goal seeking. In the seeking of any goal, there are only three possible methods: force, fraud and honest trade. Any transaction that is not an honest, mutually agreed trade will cause a self-defensive response (conflict) from the victim whose survival has been affected. "The Rule of Law" is the glue that keeps all of mankind acting together in common interest, tied together by mutual dependence of trade, on an evolutionary path to excellence. Force and fraud creates conflict and destroys civilizations. Mankind is now on a devolutionary path to extinction because the co-operation once forced by "the rule of law" has been replaced by legitimizing force and fraud for those who incorrectly believe they wield power.

In the near future, the major menace for world's population would be global warming and air pollution.  The degree of the pollution has become so high that surving in this extaordinary planet called as EARTH has become unfit.

Add to this a seed and embryo database of all the species of plants and animals that we can find before we destroy their habitat kind of like a noahs ark before the flood.

Another challenge is to find a way to recycle all the waste (organic and solid) that the humans produce.

The biggest challenge and first priority must be towards de creation of one or more solutions for clean and cheap energy. After solving this problem, Humanity will have the means to reduce other problems of the society like pollution, waste management and access to cleaner water. Logic would suggest that the sun, wind and tides should be the correct sources to use for energy harnessing. In parallel with that, investment should be made in order to abandon the centralized production of electricity, since it's transport over long distances is so inefficient. The generalized use of solar panels and wind generators in buildings should be promoted so that electricity could be produced near the consumer, thus avoiding waste in it's transportation. This would also allow for the usage of lower voltages avoiding health problems associated with very high voltages (leuchemia and others).

I was really impressed from the idea(that i also have thought) for communication with virtual reality.It means that you will speak to other persons through its digital character.Its a tremendous idea. SUGGESTION: One suggestion,that extends this idea is a robot that will actual react the same as an another person.with this way,one will talk and move and react through its robot character,from miles away. It would make the feeling that the person you want to meet is actualy in the room,although it would be only a robot and the real person is many miles away from you. Finally i think that this gadget or project would revolutianize the communication of people.For me it is the most difficult challenge of Communications Science.

I do indeed have an idea, more than one in fact, but first things first. Hydrogen power seems to be the way we are turning these days and I for one like the notion. I know the problem is a power source to actually make hydrogen resulting in possibly more consumption of resources. I say what is the feasability of a small plant that is owned by the power company (so they won't be left out of the loop and still make money) that hooks up to the water that already comes into the house, and is powered while you are away by both a small wind turbine and solar cells? Surely this can account for enough to store and use for most of our population. ( I'm just talking vehicles for now here. ) When it comes to bigger buildings or other business why not simply use the same idea to a larger degree? Based on traffic, a scale could be used to determine how much they should generate for the community, or of course, themselves. Things don't happen unless people see profit of some sort in the venture, be it either of a material or a moral/spiritual nature. This solution could provide a lot in both directions without taking away anything from anyone. Start up costs would be a lot, but they always are. I know the idea of a hydrogen generator on every structure soulds like overkill, but I feel it is more practical than central stations doing the same thing since wind and sunlight hit everywhere eventually. The only downside might be in drought stricken areas where water needs to be squandered. Solution- recycling the grey water generated from the house or business. Once it's processed leftover sewage simply gets washed down the drain with enough fluid to make it flow.

I am most interested in using incredible economies of scale to boost access to global communications and information infrastructures for both developing countries and underdeveloped populations in more advanced economies. For example, the concept of utility computing, where the applications and information you required for any purpose would be readily available over a global network (aka the "Internet"), is changing the mindset of a generation of technologists about where and how computing should take place. If you reduce the need of the global citizenry to own electronic infrastructure--through public access points, super cheap wireless smart phones, etc--then computing becomes increasingly ubiquitous, which in turn increases the economic power of successive generations. Of course, all of this computing requires power, so I voted for solar power as the most important engineering challenge.

Ironically, the safest and most abundant source of continuous, carbon-free, renewable power on Earth is right under our feet in the the heat of the crust of the Earth itself. And the technology to access it is called Hot Dry Rock (HDR) Enhanced Geothermal Systems (EGS). I call it Earth Power. And you and I already invested $100 million of our taxes dollars over 24 years in the R&D at Los Alamos National Laboratory to prove that it works! So why not use it now to solve our major problem? It's time to scale-up this brilliant long-term solution to our fundamental energy insecurity and invest in a PERMANENT Earth Power utility system that benefits everyone. Because --- buried in the Jan '07 MIT (DOE-funded) report, "the Future of Geothermal Energy", drafted by world experts in geothermal development, is the astounding estimate that, using existing technology, in the Earth's crust just in the Western US is enough accessible, convertible heat to produce SEVERAL THOUSAND TIMES all the electricity generated in the US in 2006 for SEVERAL THOUSAND YEARS! That's more than 1,000,000 years of safe, carbon-free power! Not peak oil that will end in this century. Not coal that we've still got 100-200 years to choke on! Not nuclear power with meltdown and waste problems for millions of years. Several million years of reliable, clean power -- without destroying ourselves or the world ecosystem! And Earth Power's accessability is spread over huge regions of the Earth that can be accessed almost anywhere with a tiny foot print (avoiding obvious fault lines) allowing universal decentralization for maximum energy security and optimal economic equity. And this astounding estimate only assumes the use of EXISTING technology. The HDR/EGS power-generation aspect is relatively simple and low cost. The big upfront capital cost is in drilling miles into the crust (ironically using advanced oil-drilling technology) to create the artifcial geothermal fields that generate the steam that power the turbines to produce the power. The Western US has lots of hot dry rock areas that are closer to the surface and easier to get to. That's why the experts focus on developing it first. We need the power and we've already publically paid for the technology to generate it for eons. So let's use it. Here's the really Grand Engineering Challenge for the 21st
