I ain't no physicist, or an engineer , or even a mechanic or technition: but I pushed a skateboard down a hill once, so I understand the second law of thermodynamics well enough to not get conned by this sort of thing. It never ceases to amaze me how otherwise educated people get suckered . I guess it's just like spiritualism, our disire to belive is more powerfull than logic.
Unfortuneatly, in the tidalwave of greenwwashing it's not just other people getting ripped off, our state and even federal govt. are considering spending huge gobs of money on energy systems, that people are currently doing time on fraud charges for.I came to this site because i was wandering if Penn n teller, or possibley randi were looking into this kind of thing.
It's a shame to say it but most americans are going to pay more attention to carnys than to physicist, saying there is no such thing as magic!
