Intel CTO: No more power cords

[ThePresD]

good idea but it's magnetic so the computer would fail. sorry intel

[robvh2]

He says that the human body isn't affected by magnetic fields and hence this tech is safe. This is patently untrue! Medical research has demonstrated that magnetic fields do affect the body (it has been used to improve circulation and accelerate bone healing, for instance). Also consider that MRI machines are absolutely dependent on the body reacting to magnetism (MRI = Magnetic Resonance Imaging)..

"Wireless Power Transfer" and "Energy Efficiency" are two opposing forces.

[pathshifter]

wawawiwa! i like!

Return to the "past" about Tesla and Edison's work will make a big difference for our "future". It is a very good point MIT is still our memory and Intel's experimentations will succeed following this purpose. The paradoxe and the complexity to manage Tesla ans Edison's experiences will make the difference in our future in the invisible vibes. Do "resonant circuits" offer the possibility of an another dimension ?

[Sholenga]

Have a look about Tesla's work comparate to Edison's work and the vision of our future would be quite different...we have to return to the "past" bto get a better "future" ! I agree with velazco69 and it is just a little part of Tesla's work...we still have the choice !

[inagod]

this would be something to build into new roadways,in city's, electric cars could run off power inbedded in the roadway?

[twitchd8]

so basically all they want to do is create a huge transformer, since you put one coil and then you have another smaller or larger coil to step up or down... All it is is a transformer taken out of the metal casing!! My question is will this interfere with, say, cell phone signals, or radio signals? how do we shield wireless???? A guy in this are did something similar in the past where the power company set up a sub station, and he had a coil in his chicken coop next to free power for 15 years!

[Matthijs1994]

adapters work the same way :D

but much, much smaller ;)

[zaz969]

Welcome to a new generation of power stealing!

[TravvyG]

Well hopefully SSD are STD and dirt cheap before this comes out cause doesn't Magnets effect a Hard Drive so imagine what a Magnetic Feild could do haha

[Dave21superstar]

Doesn't a changing magnetic field create an electric field?

[rsbandbj1j2j3]

dell already did something like this. they have a laptop that can recharge wirelessly with a special pad. though the range is very very short

[xxmajorsonx]

would be great for a science project

[Karpens16]

This seems unpractical. He compared this to wireless internet where in the future you might be able to get energy from anywhere. Now customers pay people to receive an internet connection and then the customers can transmit their internet to wireless networks. Would the customers have to encrypt their electricity so that it wont be stolen? Also, like wireless internet, is the electric transmitter always on? That would be a gross waste of electricity since it continuously sends out magnetic waves

[dukeuke]

Creating magnetic flux to power a device is nothing like creating an electrical signal of information. It doesn't travel near as far (all the energy it took to power that bulb only worked within a few feet), so you can't really 'tap' into someone's grid unless you broke into their home. I think they do waste to much energy, but they can be turned off as easy as a light bulb.

[pho3nixw]

I am not really understand how does it work. But I think the electricity becomes magnetic waves, and magnetic waves are everywhere, so I think it is not wasted in any kinde.

[cedwards0823]

im diggin the skullet! says older business man up front, party in the back!

[MutantBamHammer]

Dammit. I thought that this was for something else. :(

[jmac530]

does this mean you can use a regular magnet to power electronics via its magnetic field. clarification would be appreciated.

[Entzmeat]

It's already been done--

look up Nikola Tesla.

[xcatalog]

exactly what I was going to say and he did it in the 1800's.

[PureAwesome92]

Done, yes. But sone well?

[Entzmeat]

I just wanted to point out this isn't Intel's achievement and I'm actually surprised nobody had done something like this before (so we'd know about it). It's about damn time people started to experiment with the potential, and advertised they were doing so.

[MaxaminusOne]

Even if it's impractical for larger applications I think this would be extremely useful for powering things like mice that only sip electricity.

[marlls1989]

I wonder this device efficiency...

Of course they are using high frequency shifters, but any way you still have much energy lost due to the energy needed to maintain the magnetic field.

Besides that, I wonder what all that magnetic noise would do to electronic circuits near by. For sure I will never use that at home, it is like an giant trafo unconfined!

TESLA tech on future

[dLimboStick]

Use your laptop, wipeout your credit cards. YAY!!!

[IVespidI]

I try to keep a good attitude but comments like this just irritate me.

First, it was a joke. (That is indicated by "it just sounds funny")

Second, I was making an analogy between the effect coolant has on a dog and the effect magnetic fields have on magnetic storage devices. Maybe you've upgraded to a solid-state storage system. If not, you should think twice before leaving your computer next to this thing...On second thought, yeah, why don't you go do that? Let us know how it goes.

[iforgotaboutit]

I was just about to mention solid-state drives!

[fencinggearhed]

we have wireless printers wireless internet and all this other wireless stuff so why not make wirless laptop power?its a brilliant idea and i cant wait...it would be awsome if airports would have a giant version of this(without like messing up any communications between the planes and the radar and everything)so anyone could charge there laptop or the phones and all without fighting someone over the last power outlet

[MAJORdorMo]

Wireless data and wireless power are 2 very, very different animals.

[bassm0nkey]

Just wondering couldnt this be applied on a larger scale like having the roads produce the magnetic field and have it power cars. Then just use solar power to fuel the roads?

[manudath]

Its going to be massively inefficient to power the roads than the cars (something like an escalator).

Nevertheless an interesting idea.

[IVespidI]

Does anyone else see a serious problem with trying to power laptop computers using strong magnetic fields?

That sounds a little like giving your dog engine coolant to quench his thirst.

It's Intel, so obviously they know better than I do...it just sounds funny.

[nexus1g]

People seem to be getting down on this video because this technology has been around for a long time. Well, I'd like to point out that they did in fact mention Tesla and others having worked on this idea for a long time.

Please pay attention to the video before posting comments regarding this.

[Orhaach]

This is ancient technology, that they present it like it's innovation is ridiculous.

[nexus1g]

See my other post.

I will be interested to see if they will use the Earth's magnetic resonance to assist in repeating the signal for long distances.

[Torenhire]

He says in the video that it's not a new technology, just that no one has tried to put it into motion.

[Bhinder14]

This will be quite dangerous to perfect.

[fbt2007]

I could be wrong but, I think my Sony wireless headphones already use this, albeit at a very close range, to charge the batteries when sitting in its cradle. There are no electrical connections. The ear piece sits next to the charging unit which gets charged through the magnetic field created by the cradle. Wouldnt this just be a larger version?

[mypetridish]

read up inductive charging

[kitdude21]

Why yes it would

[doesitworkdotnet]

Yeah I think Sonicare toothbrushes do this?

[tommysch]

Yes, its as old as tesla.

[Nasty0suicide]

lol, nerd

[trakhull]

incredible ppl do incredible stuff ; GG Intel

[dodoshlodo]

its stupid using magnetic field, it will have no real applications... telsa's approach is way different, a modified tesla coil can do it easy

this is not new at all

[dempss]

been goin of for years with microwave rechnology. Only 20 % efficient. Fry ur brain too

[bnewman227]

apparently tesla came up with this a hundred years ago but the US govt. shut his power station down because they were worried that they couldnt meter it.

[Balmer1]

The Future? (How about security?) Nice ...

[ahassan5]

cool

[robinbuster]

I saw this at a video of MIT but it said it's not efficient. Is this more efficient than the MIT original expiriment? (how much efficiency) and does the voltage/power vary with distance?

[wildchildplasma]

I simply don't believe that the human body is not effected by these fields especially when under low clouds but good luck with your research anyway. I wonder how this concept would work at the low THz frequencies.

[chrisc62]

Would be great to have this on airplanes and at airports. My laptop battery always runs out halfway through a flight, even if I am lucky enough to sit near one of the airport plugs at the gate.

[BurtWilson1]

I can't use a high quality audio grade hifi cable (through cloverleaf adapter) with my laptop if this comes out :(

[deanfrom]

I hear you, Burt. What cable do you use?

[BurtWilson1]

Nordost Valhalla. Yourself?

[deanfrom]

Clearer Audio silver line optimus :D

wow!!

凄い！

It's a tesla amezing!!

ですか？ｗｗｗ

過去の偉大なる発明を我が物とする発表もスゴスっすｗ

[BoyintheMachine]

Tesla had the idea first and wanted to give people free electricity!

[fonett]

I worries about the adverse effect by the electromagnetic radiation.

Is there a possibility that the leukemia patient increases?

[fukuyama12392]

very nice

[velazco69]

This could be right. Intel has budget to perform any kind of experiments. However, observe that they are using a resonant circuit. They have a couple of coil-pancake. One is a transmitter and the other one is a receiver. This could be a copy or a modification of Tesla patent number 649621 dated in May 15 of 1900 (Apparatus for transmission of energy) Tesla used pancake-coil in this patent and Intel's experiment too...Also, Both are resonant circuits.

[biantai888]

This is not real! This is a viral publicity stunt. That spokesperson is Tom Cruise in an elaborate disguise!

[mapo2mapo]

OMG

[GotToPractise]

Saw this on MIT Tech Review last year. Hope it happens soon!

[foinker]

no you didn't. completely different technology at MIT.

[GotToPractise]

Is that so? Great! More brains at work.
