Soon, Power Will be Delivered to Your Device by Air

Nikola Tesla predicted that power will be transmitted by air as well as information, without wires. Wireless power could enable a whole new class of devices. Energous has a patent on an idea of putting a power transmitter into the base of a light bulb, allowing its technology to cover an entire room, and putting out enough power that a device 15 feet away could absorb one watt. They say it will be mass produced by the end of 2016. Peel & stick light switches are already common in design projects.
