A wireless power producer created by Disney researchers

siliconreview A wireless power producer created by Disney researchers

A new way to charge phone wirelessly is created, it can work by just stepping into a room, a great invention by Disney researchers. Electric devices like lamp, fan and other devices are powered without using any cables.

The efficiency is high and expected to be between 40 to 95 percent, depending on the person’s position in room. For a surprise, the amount of power can be raised above 1900 watts before the Specific Absorption Rate (SAR) in a room. The walls of the room is built acoustically with  aluminum panels, and in the centre of the room there's a long copper pipe and down  is a pipe with small section which has been cut out, and a space between there  is a ring which carries of 15 capacitors.

All we need is a coil receiver that is attached to the bottom of the phone to observe the charge. Researchers spread electric devices throughout the room and the device receives power from all position, this sounds like when a few devices like Smartphone can work then it would definitely work on other devices as well.

With a single generator placed outside room, the outputs is in a tons with a capacity of 1.32MHz, and a power amplifier placed to energize the tone, this wire connects the 1.32MHz signal to the ring of capacitors to the copper pole which indeed produce quasistatic cavity resonance (QSCR), the word used by Disney to explain the ongoing process that makes room-scale wireless power transfer possible. The most exciting part of QSCR is the magnetic field travels slowly in a circular plane around the copper pole. Which means that receiver coil is straight to that point; it doesn't produce any power which is no use while moving around inside room.

When all is turned on, the aluminum is placed where room will be filled with proper magnet that is used on coil of wire later changed to respond at one time with same frequency. Thus receiving coil is connected to a couple of capacitors, and henceforth the device has been automatically works on wireless power.
