Jesper is way off on his assertion about solar cells losing their power producing potential over just four decades, they lose some but not all of their potential after 40 years and I'll put my money on the USA for technology gains on solar into the future that dwarfs anything we have available today. If our country had put more effort and money into solar cell efficiency during the past 40 years we would be at a much better place than where we are now and I would argue that if we had done so during the Bush-Cheney lost years China wouldn't be as big a player in solar globally as they are today.
