At one point he refers to someone claiming 300W off of a 2 meter antenna. It seems too good to be true; that'd be free cheap power no one would pass up. It also sounds like something you'd be accidentally picking up all over the place with anything conductive whether you wanted it or not. Has anyone tried this? I find his demo of a tiny, barely moving engine and a 100ft wire much more realistic.
I bet it's not the "Atmospheric" power but comes from RF. Same principle of <a href="http://en.wikipedia.org/wiki/Crystal_radio" rel="nofollow">http://en.wikipedia.org/wiki/Crystal_radio</a>
