MikeChino writes: Researchers from Washington State University have published a paper in the International Journal of Astrobiology stating that energy from solar winds could replace conventional forms of renewable energy produced on Earth such as solar, wind and biofuel power. In the article, the scientists theorize that a giant solar sail, designed to harness solar winds, could generate 1 billion gigawatts of electricity. If implemented, these Dyson-Harrop satellites (named after the inventors) could tap a solar resource containing 100 billion times as much power as the Earth currently needs. The only problem is how to get the energy from space to Earth. Oh, and the fact that the solar sail would have to be 8,400-kilometer (5,220 miles) wide.
