Glaser, Peter C.


Peter C. Glaser, an American space scientist, is best known for promoting his idea of generating electricity in space for use on Earth using solar-powered satellites (1968). His idea was that satellites in geosynchronous orbit would collect energy from the Sun. The energy would be converted to radio waves and beamed to a receiving site on the ground. The ground antenna would then reconvert the radio waves to electricity for consumption. Though technically feasible, cost considerations have prevented the implementation of this system. Glaser was project manager for the Apollo 11 Laser Ranging Retroreflecter Array installed on the lunar surface of July 20, 1969, as well as for two other arrays installed on subsequent missions—the only science experiments still in operation on Earth's moon.
