Disney Come Up With A Technique To Wirelessly Power Devices In An Entire Room

While the innovation wars between Tesla and Edison spiked on the matter of transmitting free wireless electrical energy, neither of them were successful in achieving the feat due to massive technical hurdles. Since then, many people have been trying to bring the technology to one gadget at a time, from wireless charging quadcopters to mobile phones and even roads for electric cars. But none of them surely compares to what the folks at Disney Research have pulled off!

The Disney Research have just published a paper in the journal Plos One, which has revealed how they’ve successfully built the technology to provide wireless charging coverage throughout a room while powering all the devices at once!  The researchers claim that their methodology can deliver 1900 watts of energy around an enclosed room with an efficiency ranging from 40 to 95 percent depending on its position.

The room is a specially built one with aluminum paneled walls and a large copper pipe in the middle, going from floor-to-ceiling. The center of the pole entails 15 capacitors, and the assembly can resonate frequency at 1.32 MHz.

Once the pole is all fired up, the room gets covered in a magnetic field. A receiving coil resonates at the same frequency which powers the devices in the room. The 1900 watts of power is within the federal guidelines for specific absorption rate (SAR), which means that this amount of energy is safe for the human body to consume.

The precautions include not standing closer than 46 centimeters to the pole. Being present in the room is only safe if all the waves are being used to charge devices and not just bouncing off the walls, although these problems can be resolved by using a more reactive system coupled with some interior design.

Removing some kinks would mean that this technology can become as ubiquitous as Wi-Fi, which indeed makes it an exciting prospect to look forward to!
