Constellation of Cubesat for Wireless Transmission of Space Based Solar Power

摘要

A major problem facing Planet Earth is provision of an adequate supply of clean energy. It is widely agreed that our current energy practices will not provide for all the world's population in an adequate way and still leave our Earth with a liveable environment. A major task for the new century will be to develop sustainable and environmentally friendly sources of energy. Solar power is an energy source that is virtually carbon-free and sustainable. We propose a system that collects solar power by a constellation/swarm of Small Satellites orbiting the Earth. They will harness solar power using absorption of solar energy, transmit it via RF/microwaves and reconvert it to a stable DC output, conveying it back to Earth by wireless means. Comprehensive tables and graphs will be given, which will depict the amount of time that will pass at each stage of the system and more importantly some idea on the cost in terms of energy, as well as money, will be discussed within today's context. Unlike systems for the terrestrial capture of solar, a space-based system would not be limited by the vagaries of the day-night cycle. It will also eliminate the need for large spaces of land for solar farms. Furthermore, proper selection of the transmission frequency will make delivery of power essentially independent of weather conditions. Thus, Space Solar Power could provide base load electricity and this system will further help in powering future space stations as well as in space exploration propulsion.
