Alanson Sample, an Intel Research Seattle intern, shows off the apparatus for a Massachusetts Institute of Technology concept, 'Wireless Resonant Energy Link' (WREL), that can transmit power with no wires and without so much of the loss of energy that afflicts other wireless power-transmission technologies, such as induction. The technology was used to transmit 60W of power to illuminate a light bulb; it has 75 percent efficiency.
