Finally true wireless TV!
...and return of heavy, thick ass TVs
@(Unverified) And that's Made in China!!! That's Great!
@(Unverified)
Wait, what? Wireless electricity? Sounds dangerous.
@(Unverified) yeh its great but when this kind of technology catches on. your neighbourghs and people living around you with the same wireless tech, could end up using you electricity because this works up to 100feet and through walls... so thats something thats going to have to be worked on!!
@NexusElite Actually I don't think it would matter, because it's gonna be transmitting a constant amount of electricity, and whatever doesn't get used will just, well actually I have no idea what will happen to it with the whole conservation of energy thing (maybe a space heater?). Anyways, the point is it will be outputting a constant amount of power, so your neighbors connecting to it won't increase your bill, and I doubt it will actually go 100 feet anyways.
Yea, it says that the 100 feet is for the wireless video, not electricity.
What it lacks in wires it makes up for in bulk. Neat, but not too cool.
@frankinla
And cancer.
All those guys are now sterile.
So now I can finally watch tv or play Xbox on subway
@axerlzx
Yeah, dude, I can definitely imagine it "streaming" electricity off the third rail.
They should suspend the tv in the air, that would look awesome.
@suadion but then it would have wires, lol.
i do wonder about the cancer causing nature of this 'witricity'.
@alkaline
Cancer, schmancer! Wireless Electricity!
Pretty cool. Completely pointless though.
@jr amo deus
Pointless? Are you insane? Wireless electricity makes pure electric cars feasible, you see that mess of wires behind your PC, behind your TV stand? GONE. Completely. Not mostly, not partially, completely gone. Wireless electricity, video/audio, and networking.
This is the first step, this is to get people to see it is possible.
@Konrad
Your enthusiasm amuses me. Firstly, this makes pure electric cars feasible: I guess this could be true, but you would need these energy transfer boxes under the roads or somewhere wherever the car is anyway. WiTricity is only for over short distances. Also, does it even work moving between coils?
I grasp what wireless means, cheers. I am just saying that this is pointless, I don't really care about a TV that can be set 5 feet away from a wall in my living room. I would much prefer to have a TV up on the wall using a more efficient wireless energy solution.
Don't get me wrong, like I said, it's cool. For me though, it's pointless. If they were demonstrating a Netbook that never has to be plugged in, then it would be more interesting, but again, I am not sure if this solution they are demo-ing here would work for devices you walk around the house with.
WiTricity....ok then...
...not looking forward to heavier TVs
@Plazmic Flame
Because another 20 lbs on a 100 lb tv that you move once every 5 years will be such a hassle.
This is actually very useful, imaging mounting the TV on the wall without having to run any cables. Though I'm assuming it doesn't work if it's perpendicular to the box transmitting the power so that would kill it.
I can't believe the amount of people complaining about weight. Move your TV often?
Witricity is something I've always wanted.
@TrueEddie:
You've always wanted wireless electricity but at what price?
According to wikipedia, the initial test has the technology pegged at 45% efficient. That's CRAP.
Even by Witricity's own admission, the technology up to 95% efficient. Who wants to bet that is at an impractical distance (ie.: the power transmitter smack dab against the receiving unit).
Why should you care about a 5% loss? That's 5% more coal, natural gas, and what not you have to burn. How efficient do you think a simple run of the mill power cable is for that same distance? Probably 99.999% efficient comparatively).
I'm no tree hugger but in an era where we are trying to get people to conserve b/c there are 4billion other folks on this world who want the same LCD TVs, cars, and A/C that we have in the western world, simply pissing away 5% more electricity just so you can avoid having to see some unsightly wires strikes me as a completely and utter wasteful.
This is a solution in search of a problem.

@mmathers
How about video game controllers that are powered by their consoles. If batteries could be eliminated it might make the efficiency of the wireless power more tolerable. You would be saving landfill space.
@mmathers
My point was simply about weight not being a real issue.
@mmathers
Your traditional "wall warts" are a lot less than 95% efficient. Transformers of any kind are inefficient .
@mmathers well if you like wikipedia you should keep reading it and not only the portions of information to sustain your pessimist arguments, look on wikipedia energy generation or try this link: http://www.eia.doe.gov/cneaf/electricity/epa/epat1p1.html
not even 50% of energy is made of coal, co2 emitting energy sources are about 70% so 5% loss in energy does not mean 5% more co2, and this is not about just a tv that you can throw away around the room without missing your favorite tv shows, that tv is just a gimmick, the technology that powers it is the important thing and actually that 5% energy loss is just one side of it, the other side of this technology could be wirelessly powered cars wich would end with the oil dependance and ovious side effects, making the 5% loss really worth it, cars will be running on energy made 50% coal and 50% geothermal, hydroelectric, wind, solar and other alternative energy sources that means 3% more coal, against 25% less oil(14% direct use of transportation + 11% fossil fuel retreival, processing and distribution, should we consider oil wars as some kind of contamination?), and thats just the beginning, in medicine you could have a wirelessly powered heart inside your body in some years, i know you dindint said this so im saying this cause some other people mentioned it but i have never heard of cancer of sterility as a side effect for magnetic fields, i mean, we live on top of a magnet with a 6976km diameter(earth metallic cores), the earth itself is a giant magnet and we live in the middle of its field so there wont be cancer, we will all have children, stop the worries, this technology has the potential to change everything for best if just ignorance for once in human history allows science to work
Not WiTricity... Electri-fi!
9.9Mhz seems kind of scary low in terms of radio frequency that the electricity transmits at. Thats the lower alpha (around what you are at when in deep meditation) range of the brain...
sounds like a conspiracy to really vegetablize TV watchers.
call me when i can play games on it without terrible latency, till then: neato!
@Everyone who replied to me:
I concede that witricity technology DOES make sense for a wide range of devices -- mostly low wattage stuff like remote controls/controllers. Transmission loss of a small amount would be like mice nuts -- not really a big deal.
What I have a bit of a problem buying into is how this is useful for more power hungry devices. Even an LCD TV, while consumes less power than it's CRT predecessors, consumes >150watts on average when its running.
http://reviews.cnet.com/green-tech/tv-consumption-chart/
Does that make sense to satisfy someone's asthetics of having "look ma, no wires?" IMHO, no. After all, the power has to come from somewhere. If you look at this pic, it looks like the power comes from that black monolith that's sitting
BTW, unlike some other nut above me, I'm not worried about the cancer causing effects of EM fields. If this were true, I'm pretty sure I'd be pretty far down the road of having cancer b/c of all the other wireless devices in my life (phones, laptop, BT headset, etc).
