I know about the over unity energy idea. It has been proven that it exist. The reason I meantion the more mundane energy sources to illustrate the point that greed dictates our technolgy.  I just don't see what crop circles have to do with it.  If aliens were coming here across the vast distance of space why would they bother with crop circles.  By the way very cool thread I enjoy this kind of thing. The interview with  Thomas Bearden was very interesting.
