A former NASA scientist has used radio waves to transmit solar power a distance of 92 miles (148 km) between two Hawaiian islands, an achievement that he says proves the technology exists to beam solar power from satellites back to Earth. John C. Mankins demonstrated the solar power transmission for the Discovery Channel, which paid for the four month experiment and will broadcast the results Friday at 9 p.m. EDT. His vision is to transmit solar power collected by orbiting satellites as large as 1,102 pounds (500 kg) to lake-sized receiver stations on Earth.
