Powersheet provides power without wire

Capable of feeding up to 30 watts, the flexible power sheet prototype from Takao Someya, professor of engineering at the University of Tokyo, detects the power port on a gadget placed on the surface, and inducts power into gadgets modified to accept it, without needing cables. While Someya says it'll take about five years to overcome the technological limitations, his ultimate idea is to have sheets large enough to paper walls with, eliminating the need for wiring and outlets (and dozens of stupid adapters and power cables!) altogether.
