TIME's Best Inventions of 2014
4. Wireless Electricity
Witricity
In development for Toyota cars, Intel PCs and more
We already have wireless Internet and wireless phones. Why, then, are everyday appliances still shackled to the wall? To be sure, there are a few power-mat chargers for small gadgets like phones. But WiTricity, based in Watertown, Mass., is thinking big. Its technology—involving a plug-in coil that creates a magnetic field, which in turn powers objects as far away as 8 ft. (2.4 m)—has been tested on Toyota electric cars (with charging mats), Intel PCs (with charging pads) and more. Within 10 years, says CEO Alex Gruzen, rooms could be wired so that all appliances—lamps, TVs, stereos—pull power from a central charging base.
