I'm just not that gullible. The above post stated $100 per square foot, you
say $85 per square meter, over 10 times cheaper. Which is it? Now, you and I
both know you can't even lay concrete for $85 per square meter much less
install a complicated, technical mechanism. The 30% number is troubling as
well. But, at 30%, using an average daily insolation value of 5KWH, I get
547KWH per year per sq. meter. This is an average power level of 63watts per
square meter! How long and at what cost would it take to produce one Kg of
H2, the approximate energy of one gallon of gasoline, worth a couple of
bucks? Please explain how this pencils out.
