Application of the proposed solar power system to other space applications will be possible as its technical maturity progresses. PSI is developing solar thermal rocket system for satellite propulsion under Air Force SBIR funding. The solar thermal rocket system will enable communication satellites to utilize solar power for station keeping and orbit change. For terrestrial applications the proposed system will be used for a small scale, transportable solar heat source for: detoxification of contaminated soil; small power plant using compact heat engine; air conditioning cycle; and industrial process heat. The specific application of the proposed solar power system is for production of oxygen and other useful materials on the lunar surface. The solar thermal system could be set in place prior to the initiation of various lunar projects such as mining, processing or manned outposts. Therefore, the solar thermal system is the key enabling technology for building up the infrastructure for the lunar base. The solar thermal power system to be developed in this program can also be used for electric power conversion using dynamic electric power generator, such as Stirling converter.
