The Development of Solar Power Satellites

Abstract

Publisher Summary This chapter discusses the development of solar power satellites. Energy has been the key to the social development of man and an essential component in improving the quality of life beyond the basic activities necessary for survival. The amount of energy and the changes in the mix of resources used to generate power is dictated by technological, economic, environmental, and societal considerations. Although solar energy is a widely distributed resource, the cost of the equipment required to convert it makes it a challenging task to find and introduce the best methods for converting it efficiently and economically into useful forms on a scale large enough to have a significant impact. The potential of the solar power satellite (SPS) to meet future energy demands is being recognized and plans for its development are being studied. The results of extensive SPS system studies have confirmed that there are no known technical barriers to the design, deployment, or operation of the SPS. Economic studies have shown that projected capital and electric power-generation costs are within a competitive range of the costs of future terrestrial power-generation methods. Risk analyses have provided an economic justification for proceeding with the initial phases of an SPS development program. Environmental impacts have not emerged as a major constraint on the SPS operation. The SPS is one of the most promising power-generation options that could contribute to meeting global energy demands in the 21st century. Its successful implementation could lead to the elimination of energy-related concerns.
