"a power base station would be plugged into an electrical outlet and emit low-frequency electromagnetic radiation in the range of 4 to 10 megahertz,...A receiver within a gadget--such as a power-harvesting circuit--can be designed to resonate at the same frequency emitted by the power station. When it comes within a couple of meters of the station, it absorbs the energy. But to a nonresonant device, the radiation is undetectable."
