    Disney Research has constructed a prototype living room with "ubiquitous wireless power delivery," allowing users to move around while their technology charges without any cables, wires, or charging pads (via Ars Technica). Disney's technology mirrors some early rumors for the 2017 iPhone 8, which suggested Apple was building a long-range wireless charging solution instead of the Apple Watch-style inductive charging solution of more recent reports.

    The room's walls, ceiling, and floor were built with aluminum panels, and a large copper pipe was placed in its center. The middle of the pipe was cut out and in the gap the researchers placed fifteen capacitors, "and it's those capacitors that set the electromagnetic frequency of the structure, and can find the electric fields."

    To generate the power that is relayed into the room, a signal generator sits just outside the prototype living room and outputs a 1.32MHz signal to the capacitors in the pole, producing what the researchers call "quasistatic cavity resonance."
    Given that it's still a very early prototype, there's a few caveats to Disney's wireless charger, including the limit on the power that can be pumped into the room before it reaches dangerous levels for humans. The specific absorption rate, a measure of how much energy can be absorbed by the human body, is capped at 1900 watts. The copper pole at the room's center requires the nearest person to have at least 46 centimeters of clearance before they're put in danger. Besides these restrictions, Disney says it's "completely safe" for anyone to occupy the room for any period of time.

    In order for the devices to receive the charging signal, Disney had to design a receiver that allowed the researchers to "power many devices simultaneously." Including an iPhone, the other objects included an RC car, a fan, a lamp, and six other devices. Although the technology is still nascent and the receiver is bulky, Disney's "Volumetric Wireless Power for Livable Spaces" is an interesting look at what future wireless charging systems might be able to accomplish without the restrictions of the inductive charging pads popular today.


    Because of the restrictions of charging mats, Apple's Phil Schiller has said in the past that the introduction of a wireless charging pad for iPhone would actually be "more complicated" and he remained unconvinced that it was actually a convenient solution to traditional outlet and USB cable charging. Still, a prominent rumor for the iPhone 8 is its inclusion of wireless charging in some form, with Apple recently joining the Wireless Power Consortium in order to assist in the open development of the Qi wireless charging standard.

    Looks like I found a use for that stripper pole I installed back in 2003.

    Quasistatic Cavity Resonance for Ubiquitous Wireless Power Transfer.

    Try saying that 5 times fast.

    Any room that I have to be assured "it's perfectly safe to spend extended periods of time in" is a room I will not spend any time in at all. (Also please stay a half meter from the death pole at all times)

    I'm probably not as knowledgeable on this subject as I should be, but any time I read about wireless charging/electricity, I just say no thanks. I know Disney's is a work in progress thing, but when there's warnings about not touching the pole or having to stay away a certain distance, then I'll be more than happy to plug my devices the "old fashioned" way. ¯\_(ツ)_/¯

    I definitely am with you on that, but I do wonder if we are already getting the equivalent via all the radiation we are exposed to from the devices we already have...

    Wifi was treated the exact same way....

    Not in the video, but apparently what is actually required for this to work is to repeat the following lyrics:

    Sala-gadoola-menchicka-boo-la bibbidi-bobbidi-boo
    Put 'em together and what have you got?
    Bibbidi-bobbidi-boo

    Sala-gadoola-menchicka-boo-la bibbidi-bobbidi-boo
    It'll do magic believe it or not
    Bibbidi-bobbidi-boo.

    Now, Sala-gadoola means menchicka-boolaroo
    But the thing-a-ma-bob that does the job is
    bibbidi-bobbidi-boo.

    Sala-gadoola-menchicka-boo-la bibbidi-bobbidi-boo
    Put 'em together and what have you got?
    Bibbidi-bobbidi, bibbidi-bobbidi, bibbidi-bobbidi-boo.


    Be sure not to try to charge after the stroke of midnight though.

    (Seriously very cool stuff, seems like a small charging box would be very possible very soon.)

    Remember all the people last week who said wireless charging further than a foot was impossible because you can't change physics?

    Obviously this has some caveats as mentioned in the article, but this still gives very good insight that Apple could be working on something great when it comes to wireless charging.

    The energy involved with wireless power over significant distances is way more than with wifi. I admit I don't know as much about the subject as physicists, but I feel the potential (heh) for danger is much greater than with wifi.

    Yes, it's a giant microwave box!

    I think what really makes this work is the encompassing design... the energy is "captured" again by the walls, floor and ceiling, rather than flowing continuously out into space like a WiFi signal would.

    Source.

    I know it makes sense, but these are using magnetic resonance coupling to deliver the power, not beaming microwaves at you.

    Thank you Disney!! Finally we are given the hope that the misery of having to put our devices on a charging pad is about to end.

    Seriously this looks like a solution in search of a problem....

    This is why my grandparents refused to allow a color TV or a microwave in their home.

    Those Disney researchers are living in fantasyland.... Not being safe near the center of your living room is quite a big restriction... You don't have to put your devices on a charging pad (such an hassle, right?) anymore, but now you have a one meter wide health hazard / cancer inducing area in the middle of your living room.

    Oh and good luck with keeping the young kids away from the pole.... But hey it's totally worth it: you won't have to put your devices on a charging pad anymore!

    so it's not ok that they built a prototype? Everyone should build the final perfect version from the get-go?

    ...You...you understand a prototype is a proof of concept right? Disney isn't going to be shipping poles to people's friggin houses :rolleyes:

    "but there's no reason we couldn't shrink this down to the size of a toy box or a charging chest"

    Sooooooo.... instead of putting my phone on a charging pad, I will put it in a box..... oh my god ! what a game changer proposition!!!!!!

    I am saying this is dumb, pole or no pole, because it does not solve a problem worth solving.

    Have we, first world people, now become so lazy to the point we need a way to charge our phone without to have to remove it from our pocket and to put it on a pad? Really?

    And do you realize how many third world problems this technology might solve? No longer building an electrical grid infrastructure, just power generation stations that radiate power throughout a village? In doing so it allows them to utilize scarce resources in other ways.

    Then there's the fact you don't even seem to understand this article. The quote you're ridiculing has nothing to do with using the technology as a charging surface -- it's saying you're device will continue to charge anywhere in the room, but instead of a pole, it'll be a chest on your shelf.

    Yes, because technology never gets smaller. Computers today are no smaller than the computers of 50 years ago. /s

    It still is by some people.

    If fairness though, we don't have a great sample size.

    Aren't they pretty connected because of Pixar and Steve being on the board?

    Who knew Disney had bleeding-edge technology research teams??
