Submission + - Inflatable mirrors may make solar power very cheap
rhettb writes: "Inflatable mirrors for capturing sunlight could reduce the cost of solar power 90% by 2010, making sun energy cost competitive with traditional fossil fuels. CoolEarth Solar, based in Livermore, California, believes its technology could make solar farming economically competitive within three years by making solar cheaper than coal and allowing farmers to become net suppliers of electricity. The technology essentially uses a string of balloons to concentrate and capture the sun's energy without occupying valuable real estate or using large amounts of silicon."
