Wireless electricity - accomplished!

Awesome. I was trying to fault it because I was already interested in wireless electricity but as far as I've known it's not theoretically impossible but impossible for current technology. But the only thing I've found wrong with it is that he had to put the electronic devices pretty close to the coil to get them to turn on, making it a technology with limited uses right now.

I too have researched a bit of wireless electricity by tesla some years ago as I wanted to try and recreate it for a physics project. I ended up doing a magnetic braking system which was cool. Telsa's method would fry most devices these days though but apparently this new method wouldn't! He could have also provided wireless electricity for many, many people but there was no way to monitor the electricity used apparently or something like that.
It looks awesome and theres only a matter of time before this tech is in the industry. I'd predict 2012 at least though but now we know it will be in our life times which is really life changing stuff!

I've seen this on Dvice.com about 4 months ago, but it's good news that people are seeing it now!
The only reason they had to put it close to the TV was because it was pulling all the energy towards it, so they had to put it near the TV.
Now they just need to make a box about that same size that you can put somewhere hidden, and include a bunch of different frequencies in it.
I think that would be cool!

Good Stuff. They're getting further apart. OralB and others have been using this contact free charging for some time now.
I also came across a 'splash pad' which charges devices like phones etc... similar stuff. But didn't see that develop far. I was going to use the tech in a desk I designed and built but didn't have time. Nice to know OralB have used this successfully, I guess its safer to have no contact points in a steamy room... done right.
Hopefully in a few years our houses will be hooked up and everything has full battery, if that goes well then a few more years and guess what, tesla's idea might just come true, wireless electricity for the whole world. Except he said it should be free. Well in 2015 it could well be free (or just included in tax) if they develop efficient fusion generators or some other energy method.
Exciting stuff, I look forward to seeing this stuff in everyday life. My dream is to change the world for the better, maybe I could do something like this
btw its worth checking out other videos from TED, my favs (for design) are Phillippe starck and Ross lovegrove's talks. Also theres a cure for harmful diseases, (cant remember who did it) but someone developed something to aid white blood cells, effectively a cure for things like anthrax (they cured some rats of it).
Thanks for checking this thread out btw

I believe we've had wireless electricity for millions of years - known as lightning...?

Eh, the problem is still coil size.
If you notice that the phone-size coil on the back of the cell phone had a much more limited distance in which it would work from the transmitter. Polarization is also still a problem with this technology, if the recieving coil is not in the same orientation as the transmitter, the efficiency is reduced dramatically.

Static electricity is different.
Actually, the main issue is efficiency. Most of the energy dissipates in thin air, forever lost. The other issue mentioned earlier by LERsince1991 that I hadn't thought about is the monitoring of energy distrobution. Wireless energy IS an inevitable innovation sure to come within the next few decades -- if not discovered by use mere humans, the robots will be sure to figure it out. I'm sure of it.
The technology has been around for many years in the medical field. It's used to recharge implanted devices transdermally. The transmitting coil has to be within a couple of cm maximum. In air, this distance can be reduced. Also, as mentioned, it's not very efficient - it can only be used for relatively small capacity batteries - or long charge times.
