>>Does Nanosolar’s $1 per watt investment guarantee a consistent 24/7/365 source of electricity? Good point, I guess the company will get lots of returns from customers, after they realize the sun doesn't shine at night. (Not even nuclear gets anywhere close to 24/7/365.) >>That's the trouble with government subsidies -- they allow people to operate outside the constraints of reality. At taxpayer expense. That is true, of course. But $1/Watt is the often quoted threshold where solar cells get economically viable for more solutions. For example, it means that there will be relatively few years to get back the investment for solar cells to drive air conditioners. (I've only read about air conditioners' energy use. I live where there are no problems with lots of sunny and warm weather, sigh.)
