Disney's new OTA charging technology has plenty of potential



The folks at Disney do a lot more research than trying to figure how how much to raise theme park ticket prices. Lately, they have been looking at quasistatic cavity resonance. It is based on Nikola Tesla’s coil circuit that produces an energy field. The idea is to allow someone with a mobile device to walk into a room and have the phone in his pocket charged OTA without wires and without pads. Yes, this is a charging solution that Energous has already started to address with its WattUp product.

Disney built a mock living room to test its wireless charging technology. Devices such as a smartphone, a lamp, a remote control car and a fan were charged up by the roaming energy. 1900 watts were sent into the room; any more could be dangerous to the human body. In the middle of the room is a long copper pole containing a ring of  15 capacitors. The wall, floor and ceiling are made from aluminum panel. 

When things are turned on, the current is running up and down the copper pole at a speed of 1.3 million times per second. The current goes up and down through the room, creating a circular magnetic field that travels around the pole. Multiple devices can be charged at the same time depending on the design of the receiver employed. Disney has advanced the system so that it provides power regardless of the orientation of the device. Furniture placed inside the room by Disney did not negatively affect the circulation of the energy.

Disney scientists say that the technology can be scaled down to "charging cabinets" or scaled up to huge warehouses. A lot more testing needs to be done before all of the potential of this system becomes available to the public.

Finally a wireless charging tech that makes sense... Can't wait to see it implemented in buildings, cafe shops, libraries, schools, etc... nice

Who would've thought, It would be Disney making waves in the tech world

Disney is a worldwide leader in several industries.

Eagerly waiting for this. The first device that comes with over the air charging will be the new distruptive device like the iPhone was in 2007. I will switch from iPhone to a device that has over the air charging. For me that's bigger than all the features combined since 2007. It's a leap on technology that may change our entire infrastructure.

a device like this needs infastructure to support what good is a device with over the air charging if there's no over the air chargers anywhere ???

Not saying Apple will be the one, but from what I've seen Apple is pretty good at prepping an infrastructure before putting a feature in... Hence - Apple Pay (got bunch of banks involved before releasing an iPhone with NFC), 3D Touch - 3rd party developers had apps ready before releasing an iPhone with FT). Compare that to Android: Google Wallet got blocked instead of being accepted, barely seeing any use until 2 years later when Apple added NFC payment to its ecosystem. Forcetouch on that Chinese android device does nothing outside it's own few apps - absolutely zero third party developer support even today! So, I'm not worried - 3rd party accessory market supports iPhones and iOS device quite well right from the start. But I'll reserve my discretion till I see it and I can buy it...

Apple Disney Energous Tesla and that one Kickstarter campaign all have the right idea. Bring true wireless charging to the table. Not this gimmick crap that Samsung and others currently boast about.

The current stage of Wireless charging isn't gimmicky crap. It's more convenient using the pad when you break the charging port on your phone rather than paying upwards of $150 for a crappy refurbished device Also until this wireless tech can be shrunk down to consumer levels it won't be a viable solution in home.

Probably going to give you cancer but at least your phone will be charged.

Where are the Disney engineers in those pics? Seems they're scared to even go into the room seeing they used an RC car. There are people that are sensitive to EM fields produced from improperly shielded power cables and this tech would probably send them to the hospital.

What about people with pacemakers, do this technology interfere with it in any way? It's harmless to hearing aid equipment of deaf people? Also, if my device is at 100% does it continues to charge, or somehow the OS shuts down the charging receiver? Those are the first things that came up to my mind, of course there are way more to consider...

Hell to the no for me. I'm more than fine with micro usb. This cannot be good for your body

Yeah, I don't see any potential problem to introducing a current into the air, that might be picked up by who knows what. I mean it sounds nice, but I don't know..
