Really? Just using "round numbers" to make the math easier; a square yard
of real estate gets--let's call it a kilowatt of solar irradiance. That
square yard contains--lets call it a thousand square inches. That comes out
to--lets call it 1-watt per square inch. That would seem to indicate that
their "Nanosolar" material is able to generate 120 times more power than
falls on it. Quite a trick. I'd love to learn how *that* was done...
