Researchers are claiming that the obstacles to wireless power transfer can be overcome—at least at distances up to 12 feet.

The Massachusetts Institute of Technology announced the development of wireless power beacons on Tuesday (Nov. 14) at the American Institute of Physics' Industrial Physics Forum in San Francisco. MIT claims that historical obstacles to wireless power transfer through space are surmountable, and perhaps enabling the wireless recharging of batteries.

Called "nonradiative resonant energy transfer," the technique harnesses omnidirectional energy beacons without the requirement for unobstructed line-of-sight. The technique wastes no energy and is eco-friendly, MIT claimed.
