Wireless power transfer up to 12 feet
MIT is working on wireless power beacons that can transmit power up to 12 feet, even through obstacles. This could potentially enable truly wireless wireless devices. The artical doesn’t mention anything about how much power can be transmitted. Presumably, it’s not enough to power your 60″ plasma TV.
Imagine a house with a power beacon at every electrical outlet. All low power devices could stay constantly charged. Way cool!
