Have you ever thought of being able to charge your phones and gadgets on a room without any wires connected? If yes then get ready now for it have arrived on this world’s reality.
Disney presents us with the most anticipated live action movie of The Beauty and The Beast. And now Disney also presents “The” amazing wireless charging room that will charge your phone wirelessly. Disney Research (real live Tinkerbell’s workshop XD) reveals a room-filling, wireless charging breakthrough that will allow you to waltz around the room while charging your phones.
Researchers built a free-standing room with aluminum panels covering the walls, floor and ceiling. In the center of it, a two-inch copper pipe runs vertically from floor to ceiling (We said it was ugly). Electric current runs down through the pipe, into the floor, up the walls, over the ceiling and back into the pipe, looping at 1.3 million times per second. That looping electricity creates a room-filling magnetic field that runs in a circular pattern perpendicular to the pole. In the center of the length of pipe, they placed an array of capacitors. The in-pipe capacitors manage the electromagnetic frequency, lowering it until the electric and magnetic fields are separated. Basically it’s an electromagnetic field, without the electricity.

Wireless power delivery has the potential to seamlessly power our electrical devices as easily as data is transmitted through the air. However, existing solutions are limited to near contact distances and do not provide the geometric freedom to enable automatic and un-aided charging.
We introduce quasistatic cavity resonance (QSCR), which can enable purpose-built structures, such as cabinets, rooms, and warehouses, to generate quasistatic magnetic fields that safely deliver kilowatts of power to mobile receivers contained nearly anywhere within. A theoretical model of a quasistatic cavity resonator is derived, and field distributions along with power transfer efficiency are validated against measured results. An experimental demonstration shows that a 54 m3 QSCR room can deliver power to small coil receivers in nearly any position with 40% to 95% efficiency. Finally, a detailed safety analysis shows that up to 1900 watts can be transmitted to a coil receiver enabling safe and ubiquitous wireless power. (disneyresearch.com)
It may sounds unsafe, but it was already been tested as safe for humans inside the room. Although it seemed to be not quite working for iPhone yet.
Be ready people, we might gonna see a city like the one in the Meets The Robinsons animation movie soon. We humans are often get inspired by these future themed shows after all. “Be creative and never afraid to try” is the best quote for this I guess. Will you be the next inventor and go down to history?
