Grand Challenges for Engineering - Jul 29, 2014
On February 15, the National Academy of Engineering will announce the Grand Challenges for Engineering. Input came from many sources, including you.
I just want to announce that YES, atmospheric heat can be harnessed successfully. For a long time, this has been considered to be against 2nd law of thermodynamics and therefore "impossible". But, now it has been done successfully.
Two Venezuela born inventors have made a machine capable of extracting atmospheric heat and converting it into power/electricity. A prototype was made and tested found that the output is 23 times more than the input.
I think this is a great idea, and I truthfully have no idea how this would work other than the fact that the laws that apply to us right now on earth, apply to the molecular machines. You would need to somehow use tools smaller or the same size as the molicules themselves, then try to manipulate the molicules without them sticking to the surface of the tool. You probably need to use some type of robotic arm that can make miniscuel movements so you can therefore sucessfully create the molecular machines. Even then I still don't see the great advantage of molecular machines other than to help hospital paitents with extremely small mutations in a cell or somthing similar.
