Ars Technica UK reported that the living room prototype was built out of aluminum panels. The researchers placed a long copper pipe, discrete capacitors and drive coil inside the room, while on the outside they installed a signal generator and power amplifier. During the experiment, they managed to charge 10 different objects, including a smartphone, a lamp and a fan, without having to use any cables.

The wireless charging room is said to use a method called quasistatic cavity resonance (QSCR), which generates magnetic waves to fill the interior of a room with electrical power. The QSCR method works similarly to Wi-Fi and can pump around 1900 watts into the room at an efficiency of between 40 to 95 percent, depending on the receiver’s position.

Disney Research’s associate lab director and principal research scientist Alanson Sample told phys.org that the innovative method would make it possible for electricity to be as ubiquitous as Wi-Fi.

"This in turn could enable new applications for robots and other small mobile devices by eliminating the need to replace batteries and wires for charging,” said Sample. (jes/kes)
