The latest MIT news flash could finally allow consumers to cut their power cords: A Massachusetts Institute of Technology research team has figured out how to wirelessly illuminate an unplugged light bulb from seven feet away.
Within the next five years, MIT physicist Marin Soljacic foresees a day when people could forgo the tangle of wires that keeps laptop, iPod, and cellphone users on a short leash. Instead, they could use a carefully designed magnetic field to deliver power to devices over the air. "At this point, this is a proof of principle -- the main point of our research was to see if we could transfer energy wirelessly," said Soljacic, who was inspired by the annoying beeps his cellphone made in the middle of the night when he forgot to charge it. "It occurred to me that it would be so great if the thing took care of its own charging."
