This sounds awesome to be fair (if its safe lol) I mean you could speculate of have items sharing battery energy like an invisible wire with this theory I cant believe they dont see much of a home usage??? er wireless speakers? wireless tv's? I mean how many damn wall sockets do I have just to power my electricals!? this could replace the wall socket for appliance power connection :)

imagine - a wireless iron where the damn wire no long moves your clothes when your trying to remove a bad crease!

no more multi sockets with 7 wires sticking behind your tv

wireless speakers around your house so it doesnt look so messy!

so many applications!

*edit* more here

I don't know it it would able to power something as power thirsty as an iron or kettle/tv etc.

More for recharging little things.

well they were stating refridgerators - Im guessing it will be little things at first - but I like the theory in to it he if it replaces a single wire to power an iron or my pc I would buy 50 of them
 
It all works in magnetic induction. Seeing as how intensity will decrease by the inverse SQUARE law, there will be a lot of wastage.

Also, if you still want to charge or power anything, the power output of the source will be quite large. I dont want it to be near muh 'ead or nads either.

I'll believe it when i see it....

The aerials are quite large :p

Although presumably for something small like a phone etc, you could use smaller ones.
 
Nice in theory, but flawed in practise. As pointed out, its hugely wasteful among other problems. Lets face it, a wire is a highly effective means of transferring both power and signal; observe how much worse wireless internet is in comparison to ethernet! With portable applications (which will be the only ones with any real point) then I can see the power level changing depending how far you are from the source. Imaging your theoretical wireless lawnmower, grinding to a halt toward the end of your garden :D:rolleyes:
 
I has something to do with the new areials, the coil shape/size in comparison is apparently much much better than anything they have used in the past (as well as some frequency technical thing i forget :o)

But just imagine your desk being a charger, not having to plug in mice/KB/phone/ipod etc.

While they are sitting on the desk. That would be pretty sweet.
 
A lot of rechargeable toothbrushes use wireless charging already. But the thing is with that is that there's not much distance between the output coil and the input coil (those are my words, I don't know their proper names even though I did them in physics a few months ago :)), it's probably the same with a fridge as well, as they're usually right next to the wall where a wireless socket could be placed.

But like other peopel in the thread have stated, once you start getting further away, the amount of energy transferred drops massively, and you have to compensate for that by upping the voltage to huge amounts.

I can see it working for items that are usually static when they're consuming power (eg fridges or toothbrushes like I've said, but I wouldn't go as far as saying ovens or anything that consume as much energy as that), but portable things like irons or lawnmowers would probably make things a little more messy.

Edit: Like doonhammer said, I'd be worried about the massive fluctuating magnetic fields that were passing through my house and me if I used this kind of technology. All the birds would be migrating to my back garden :p

I would be more concerned on any effect, in my head or otherwise. That it would have on my groin region if I am honest. :p
 
Why are people so short sited. It is new you gimps, it will likely become more powerful/efficient and smaller.
I hate having loads of different chargers for things, this would be amazing.

Thats fairly sensible actually. The portable devices won't take much power and the desk could be a large radiating surface plus the devices will be in close contact with it. Heath risks, I don't know, not as bad as trying anything long range/high power though.

Does anyone else find powering a fridge like this just totally pointless? I mean, at what point have you been concerned with how your fridge is powered, its not like you move it around lots is it :confused:. You just plug it in and leave it alone :)
 
Electric hobs have been like this for ages, they use electromagnetic induction. Anything long range however would cause electronic devices to burn out that can't handle the current. As you moved the device nearer to the transmitter the power would increase by the square law until it blew.
