Disney has created a concept room for wireless charging phones. It's a cool idea but a bit ambitious for anything soon
https://www.extremetech.com/extreme/244809-disney-creates-room-can-wirelessly-charge-hundreds-devices
The researchers built a full-scale room to demonstrate the technology. The walls, floor, and ceiling are all made of aluminum panels. In the middle of the room is a copper pole that allows current to loop through the room’s structure 1.3 million times per second. A series of capacitors in the central pole make sure the electric field is confined so it doesn’t interfere with anything in the room. That’s why objects and people can walk around in the volumetric power room without harm. It meets all federal safety guidelines (mostly). Outside the room is a generator and power amplifier to pipe power into the ring of capacitors.
