Disney develop Disky "Quasistatic Cavity Resonance (QSCR)" technology to make the entire room a charger

Disney's research facility "DisneyResearchHub" is "Quasistatic Cavity Resonance(QSCR) ", a new technology for wireless power transmission. QSCR is a technology that can transmit power to the whole space closed like a room and charge various devices.

How to use QSCR to transmit power to the whole room like this is easy to understand when you watch the following movie.

DisneyResearchHub is a technology for generating a quasi-static magnetic field in a space partitioned like a room and transmitting power. A special room of 54 cubic meters is used in the experiment, and the center of the room is equipped with a driving coil and a pole.


First, the signal generator outputs a tone signal of 1.32 MHz.


The power amplifier amplifies the power of the tone signal.


The tone signal amplified by the power amplifier is connected to the driving coil installed in the room.


Capacitor for setting resonance frequency and electric field is attached to the pole which is set at the center of the room.


Current flows in the order of "Paul → ceiling → wall → floor" ...


Generate a magnetic field centered on the pole.


When the receiving coil is held over the generated magnetic field, the light attached to the receiving coil lights up.


Floor and ...


You can see that power is being transmitted even in the corner of the room.


Electricity is supplied when the coil is set perpendicular to the magnetic field, and power supply stops when it is level with respect to the magnetic field.



Next is experiment with a small electric fan of 5W. When the signal generator is off, it is not working at all.


When the signal generator is turned on, the blades of the fan rotate.


When it is level with respect to the magnetic field, the fan switch is turned off.


Try it on the iPhone this time. When it is horizontal to the magnetic field, the screen is pitch black ... ....


When vertical to the magnetic field, the battery icon on the upper right of the screen changed during charging.


By using QSCR, it is possible to charge a large number of devices at the same time with the entire room like a charger. In the experiment I could output up to 1900 W and I do not know how this technology can be used for Disney's works and products, but it is certainly a technology that makes me excited.
