Disney Develops Wireless Charging

The people at Disney Research has built a room where mobile devices can be wirelessly charged.

After working their idea out on paper, Sample and his team tested it by building a special room and powering various devices inside. A copper pipe was erected in the middle of it – a little like a pole-dancing set-up – while the walls, ceiling and floor were lined with aluminium panels. 

Currents ran up and down the pole 1.3 million times per second, generating an oscillating magnetic field at that frequency.

The field can deliver up to 1.9 kilowatts of power inside the room, “which is equivalent to charging 320 USB devices,” the authors write in PLoS One. In a demonstration, Sample’s team operated lamps, a fan, a toy car, a phone, a fan and some LEDs simultaneously.

And no, this is not yet built at any of the parks, so you'll just have to wait!

You may get the open-access paper of the work here.
