Solar power to satisfy the earth's enegy needs within 20 years

Ray Kurzweil - solar will power the world.

Solar power, driven by exponentially-increasing nanotechnology, will satisfy the entire world's need for energy in less than twenty years.

Currently, solar power supplies less than 1% of the world's energy needs, which has led many to disregard its future significance. Where they're wrong is that they fail to understand the exponential nature of technology, says eminent inventor and futurist Ray Kurzweil. Just like computer processing speed—which doubles every 18 months in accordance with Moore's law—the nanotechnology that drives innovations in solar power progresses exponentially, he says.
