Project Selene, NASA, 1992 2. Smaller Projects I Demonstrations Microwave Ionosphere Non-Linear Interaction Experiment (MINIX) (1983) A mother-daugher power beaming experiment launched on a sounding rocket in 1983. A single magnetron was used for transmission. Japan External Trade Organization, Solar Power Satellite R&D in Japan, New Technology Japan, 1991 Russian SPS (TsNIIMash) Illustrated below, this is a seventy tonne structure in circular low earth orbit. It produces 250kW for beaming to earth. The power station is manned by cosmonauts who carry out adjustment and repair work, and is launchable using existing vehicles.

Power from Space, Soci^td des Ingdnieiurs at Scientifiques de France, p. 381,1991 IGRE's 100kW demonstration project A general discussion of the issues involved in providing space power, with an emphasis on third world participation. IGRE is a proposed not-for-profit organisation (Institute for Global Rural Electrification) to bypass the structures of government and build a hardware infrastructure. Initial demonstrations would transmit lOOkW at 2.45GHz to Earth. Low earth to geostationary orbit transfer would be accomplished using ion rockets powered by cells on the spacecraft.

Power from Space, Soci£t£ des Ing6nieiurs at Scientifiques de France, p. 393,1991 SHARP This is a project aimed at the creation of a high-altitude communications platform for Canada. In 1987 a small airplane flew powered 500kW of energy beamed at 5.8GHz. A larger airplane has been built and tests are imminent. The planned configuration is illustrated below.
