JCP, I saw the prices of said rooftop solar panels. Not very economical at the moment. But at least that's more practical than 100 square miles of solar panels sitting out in a harsh desert environment.

Next step: How to run our cars using solar power ...

I'd rather see the 100 square miles on people's roofs.


Is that even possible.

100 sq miles is 2,787,840,000 sq feet.

If the average roof was 1000 sq feet (I don't know the actual average size, if you have a source for that I'd plug it in to the equation), than 100 sq miles would be 2,787,840 houses. So yes it would be possible (if very expensive).

OTOH some estimates say we would need more like 10,000 square miles (or 278,784,000 1000 sq foot roofs) or 20k sq miles (over a half billion roofs) or more, such as the 220,000 square kilometers estimate here - msnbc.msn.com . That last estimate would be almost 82k sq miles or over two billion roofs.
