JF, from the article, > Then he turned to the sun, his research focus, which bathes the planet in 800 terawatts of energy continually. “We only need 18 of those terawatts,” he said. OMG, does this professor from MIT know basic math? Total surface area of Earth: 510 million km2 (from Google Earth) That means about 255 million km2 is bathed in sunlight at any given moment. If that represents 800 terawatts of solar energy, then to get 18 terawatts we need about 5 million km2 of solar panels at 100% efficiency, or half the size of America. Bottom line: It's NOT the sun, stupid. Tenchusatsu
