Solar Power From Outer Space Could Reduce Fossil Fuel Dependence

Rising fuel costs have spurred some pretty wacky ideas. One that maybe isn’t so crazy is harvesting solar power from space. While the idea isn’t new—NASA and The US Department of Energy studied it throughout the 1970s—the time has come when it might not be too expensive to start pursuing it.

Pravna Mehta, the director of India operations for Space Island Group, a company working to develop solar satellites, thinks space energy has excellent potential. According to his vision, satellites would electromagnetically beam solar energy to ground-based receivers, where the energy would be converted to electricity and transferred to power grids.

Since satellites in high Earth orbits are unaffected by earth’s shadows, the energy would be available every day without fail.
