Satellite solar panels in orbit to capture sun's rays 24/7 & wirelessly beam energy down to Earth
(quote)
Pacific Gas and Electric, which serves San Francisco and northern California, is to seek approval to buy 200 megawatts of energy from solar power firm Solaren. Within seven years, Solaren plans to send a satellite equipped with solar panels around 22,000 miles into space on board a conventional rocket.
Satellite solar cells would capture the sun’s rays 24 hours a day, without fear of cloudy mornings or dark nights. The orbiters then convert this solar power to radio-frequencies that transmit to ground stations in Fresno County, Calif. Once received, the radio energy would change into electricity and flow into the grid.
Sunlight in space is at least ten times more powerful than that on Earth, making orbiting solar panels far more efficient than those which are land-based. Solaren believes the technology could provide enough clean electricity to power at least 150,000 Californian homes.
