Solar Power stories

To build a solar power plant, you need two things: lots of energy, and lots of silicon. The Sahara desert can provide scads of both, and by using power plants to 'breed' more power plants, the Sahara Solar Breeder Project will theoretically be producing enough green energy to power half of humanity by 2050.
How much easier can it get? A company called SoloPower is rolling out flexible solar panels that it hopes will soon grace the flat roofs of office buildings. Looking at something like this, though, you can't help but think how great it would be if you could just toss it on your own home.
