There is an increasingly intense need to harness solar energy due to an ever growing shortage of conventional energy sources, The instant invention is concerned with method and apparatus for solar concentrator micro-mirrors on solar power satellites and the moon to focus and reflect large quantities of solar energy. Method and apparatus are taught for directly reflecting solar energy to the Earth; reflecting solar energy to a microwave converter in space which transmits microwave energy to the Earth; and reflecting solar energy to a laser radiation converter which beams laser radiation to the Earth. The concentrated energy received at the Earth may be converted directly to electricity or indirectly by thermo-mechanical means. The advantages and disadvantages of the different means of sending such concentrated energy to the Earth are discussed. A particularly important objective of this invention is the focussing of sunlight for solar power conversion and production. The instant invention can contribute to the goal of achieving environmentally clean solar energy on a large enough scale to be competitive with conventional energy sources.
