The Universe is full of energy. All kinds of ways to get it without even getting into advanced Idea's. To name a few; tidal, wave action, geothermal, solor, wind, hydro-electric. I would have to agree about the crop circles being BS. Supressing technology does not suprise me however. I mean there are places you can get killed for $10 do you really think that the kind of money Big energy companies control they wont do worse.  Tecnology will only be allowed to advance to the point a profit can be made. Greed rules the world unfortunaley.
