INTRODUCTION Power from sunlight — a long-time dream of philosophers and inventors — is hecoming an engineering reality. Solar heating and cooling is beginning to undergo commercial development. A pilot plant phase has begun for groundbased solar electric plants. The

Cost and economic analyses have indicated promise of commercially competitive electric power costs even i f the development of the powersat i s amortized by operational revenues. A busbar cost of 6.9 mills ($0.0069) per megajoule (25 mills ($0.025) per

The size of the power sat is awesome, primarily because normally space payloads are throught of as being fully assembled on Earth and then launched into space. Skyscrapers, dams, or nuclear powerplants would be equally awesome if they were thought
