Implications for the UK of solar-power satellites(s.p.s) as an energy source

Rapid depletion of fossil-fuel resources is leading to increased interest in alternative energy sources. The sun´s radiation in space is a continuously available, virtually nondepletable and environmentally benign source of energy which could be made available on earth by the s.p.s. concept. This paper describes the concept currently under evaluation in the USA, and also in Europe (particularly in UK), though to a lesser extent. The advantages and problems associated with its adoption by the UK as a major source of electrical energy are discussed.
