While searching net, I recently have come in touch with two very interesting patents. Both applications were patent granted. Both claim to produce electricity by using atmospheric heat. Here they are: 1)http://patft.uspto.gov/netacgi/nph-...50&s1=6938422.PN.&OS=PN/6938422&RS=PN/6938422 2)http://www.freepatentsonline.com/y2008/0061559.html The general notion regarding this matter is "atmospheric heat" can't be extracted and any machine or technology that claims to extract that actually violate 2nd law of thermodynamics and thus cannot be made in reality. But, those two above are patent granted and I don't think that the patent examiners are that idiot not to know about 2nd law of thermodynamics. Moreover, the description too is available. Therefore, all readers are requested to go through the description before making remarks.
