Space Based Solar Power

Dating back to 1968, Peter Glaser proposed the idea of space based solar power. Now decades later, with  depleting natural resources and skyrocketing prices a renewed effort to use space based solar power is underway. The proposed concept involves large geo-synchronous satellite arrays that collect the sun’s rays 24 hours a day. Solar power could then be beamed to the Earth’s surface using large solar collectors. NASA and the DOE have spent $80 million over the last three decades investing Space Based Solar Power (SBSP). The idea was officially revisited by National Security Space Office, Advanced Concepts, in 2007 and released a feasibility study that concluded the SBSP does present a strategic opportunity for the US.
