Satellite Power System (SPS) is concept that transforms solar energy intercepted in space into electrical energy usable on earth. 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. Each satellite would be equipped with a solar cell subsystem to convert solar energy to electrical energy, a subsystem for generating microwave frequency energy, and an antenna to beam microwave energy to earth. A subsystem on earth would receive and process the microwave energy for insertion into electrical utility systems.
