Harvesting Solar Rays in Space

http://www.alternative-energy-news.info/harvesting-solar-rays-in-space/
When in distress we often look towards the heaven to find an answer to our problems. West coast energy giant, Pacific Gas and Electric (PG&E) is doing the same. They are heading towards heaven to trap the sources of renewable energy. This company’s main operations are in San Francisco and northern California. They are trying to get approval from US regulators to purchase 200 megawatts worth of solar energy delivered from solar panels located in space. There is nothing new in this proposal. Pentagon conducted a study on similar lines in 2007. Pentagon study concluded that satellite based solar power is feasible but not economical. It will cost a leg for potential consumers. But PG&E and its partner Solaren that will build the solar panels, quash those fears. They assure that their costs will be comparable to rates for other lines of renewable power. But how? They are not answering that! But Solaren claims it has developed a technology that would make it commercially viable within the next seven years.
Solaren CEO Gary Spimak said, “While a system of this scale and exact configuration has not been built, the underlying technology is very mature and is based on communications satellite technology.” For over 45 years, satellites have collected solar energy in Earth orbit via solar cells, and converted it to radio-frequency energy for transmissions to Earth-receive stations.”
