The thought of turning solar energy from space into electricity and beaming it back to earth goes back to the days of Sim City 2000. This technology could be in a our near future as scientists now think this possible with current technology. Scientists believe that satellites rotating around the earth could beam down 5-10 gigawatts of continuous, renewable energy. Mr. Bova in a recent article with the Washington Post believes just one of these satellites could power all of California.
If they could beam this energy to more than one focal point, imagine what we could do with that. For now we will just have to wait and see if one of these is actually launched in the near future.
