Wireless Power

First we had wireless telephones, then wireless wireless power? An old college pal sent me an article about arrays in orbit transmitting power via microwave. Pretty high-tech!

"Funded by the Discovery Channel, John C. Mankins finished a four month experiment which began by collecting solar power, nothing out of the ordinary. What happened next was relatively extraordinary, though -- he transmitted the power 92 miles (148 km) between two Hawaiian Islands. Terrestrial power transmission is only of interest to Mr. Mankins as a proof of concept. Mr. Mankins' true plans are out of this world. He envisions a network of 1,102 lb. (500 kg) satellites beaming solar power collected from panels back to Earth, satisfying all the world's power needs."
