I was arguing with someone on facebook about solar and other types of energy when he starts talking about free energy and govt cover ups of it. I dont really know how to argue with that because I dont know much about them. All I could do was ask how that's working out for him. I was linked to this site... http://www.freeenergyparty.org/ And http://www.greenoptimistic.com/2010/12/25/karpen-pile/#.UXwd77VOT0c I found a site trying to sell plans for a karpen generator, but its obviously a scam. It seems interesting though...a battery that never dies. http://www.karpengenerator.com/vsl/?src=BEN-CB Anyone have any knowledge of these sorts of things? I know they cant be viable or there would be people on GT posting about them...particularly the posters who have solar arrays and are trying to live off the grid.
