A room where your phone will never run out of battery

Wireless Charging pads is existed and booming nowadays, but they are too far from perfect.
Wireless Charging pads worked by running a high frequency into a circular coil which creates a magnetic field that field into the another receiving circular coil of the device and the device convert into the electricity to charge your smartphones.

BUT
If you move the device even a little, the device will stop charging until you stop moving the device it will charge again. This kind of wireless charging pads is not perfect yet.

The real wireless charging is a wireless charging in a distance something that can keep you top up while you're walking around and using your smartphone. Researchers from Disney has an answer to this.

Their solution is to design a room that has a giant 3 dimensional charging pad.

It looks like a normal room but the difference is that, it has a giant copper pole in the middle of it.

If you have a receiver that matches with the right frequency you've got a wireless charging almost anywhere in the room.

The room can transmit enough power to charge up to 300 smartphones without exceeding the government guidelines for how much power a human body can absorb, so as long as you are standing at least 46 centimeters away from the pole you shouldn't have to worry. And you should not touch the pole.
