Office of Energy Efficiency & Renewable Energy – SPS (Satellite Power System)

Concept for providing large amounts of electricity for use on the Earth from one or more satellites in geosynchronous Earth orbit.  A very large array of solar cells on each satellite would provide electricity, which would be converted to microwave energy and beamed to a receiving antenna on the ground.  There, it would be reconverted into electricity and distributed the same as any other centrally generated power, through a grid.
