The search for a new, safe and stable renewable energy source led to idea of building a power station in space which transmits electricity to earth. The concept was invented by Glaser in 1968. Research is going on in this field and NASA is planning to implement one in near future. SPS converts solar energy into microwaves and transmit it to a receiving antenna on earth for conversion to electric power. The key technology needed to enable the future feasibility of SPS is Microwave Power Transmission. It would be a massive structure. Estimated cost is about $74 billion and would take several years for its construction. Suggestions are made to employ extra-terrestrials resources for its construction. This paper throws some light on solar power satellites and the application of microwave power transmission in order to meet the energy demands sustainably.
