Power via Wireless

“Massachusetts Institute of Technology researchers made a 60-watt light bulb glow by sending it energy wirelessly – from a device 7 feet away – potentially heralding a future in which cell phones and other gadgets get juice without having to be plugged in.The breakthrough, disclosed Thursday in Science Express, the online publication of the journal Science, is being called “WiTricity” by the scientists.

The concept of sending power wirelessly isn’t new, but its wide-scale use has been dismissed as inefficient because electromagnetic energy generated by the charging device would radiate in all directions.”
