http://afp.google.com/article/ALeqM5jn6 … wuv389gooQIntel on Thursday showed off a wireless electric power system that analysts say could revolutionize modern life by freeing devices from transformers and wall outlets.
Intel chief technology officer Justin Rattner demonstrated a Wireless Energy Resonant Link as he spoke at the California firm's annual developers forum in San Francisco.
Electricity was sent wirelessly to a lamp on stage, lighting a 60 watt bulb that uses more power than a typical laptop computer.
Most importantly, the electricity was transmitted without zapping anything or anyone that got between the sending and receiving units.
"The trick with wireless power is not can you do it; it's can you do it safely and efficiently," Intel researcher Josh Smith said in an online video explaining the breakthrough.
"It turns out the human body is not affected by magnetic fields; it is affected by elective fields. So what we are doing is transmitting energy using the magnetic field not the electric field."
Examples of potential applications include airports, offices or other buildings that could be rigged to supply power to laptops, mobile telephones or other devices toted into them.
The technology could also be built into plugged in computer components, such as monitors, to enable them to broadcast power to devices left on desks or carried into rooms, according to Smith.
"Initially it eliminates chargers and eventually it eliminates batteries all together," analyst Rob Enderle of Enderle Group said of Intel's wireless power system.
"That is potentially a world changing event. This is the closest we've had to something being commercially available in this class."
Previous wireless power systems consisted basically of firing lightning bolts from sending to receiving units.
Smith says Intel's wireless power system is still in an early stage of development and much research remains before it can be brought to market.
Rattner spoke of technological transformations he expects by the year 2050.
"You'd like to cut the last cord," Smith said.
"It's great that we have wireless email and wireless internet and stuff like that but at the end of the day it would be nice to have wireless recharge as well."
holy shit that sounds incredible
I think the problem with Wireless energy is interference. As it says,"The trick with wireless power is not can you do it; it's can you do it safely and efficiently,"
With Interference you're not very efficient
I have to go to a party nao, I shall bring back caek!

Sounds cool.
yeah wonder if the technology will pick up so everything goes wireless even electricityliquidat0r wrote:

Heh, a while back I was talking about this with my dad. Of course, sending a shit load of electrons through the air is going to fuck everything up. But I am skeptical about the magnetic field. How will it be able to be efficient, yet not be so strong that it screws up the devices it is powering, or other devices?

Naw not really... It more to do with building a big enough current.Gooners wrote:

Any time a charged particle moves in a magnetic field it experiences a force... Like wise any time a magnetic field moves relative a charged particle it experiences a force...
So anytime a changing magnetic field passes through a wire the electrons are forced through that wire. Its called induction. It doesn't matter if the magnetic field has a constant change, a sine wave, or a random interference pattern... as long as the field is changing a current is generated. The current may change directions, or intensity.... but just like changing AC to DC that can be fixed.... And even if the voltage isn't particularly stable it is still a potential difference that can be used to recharge a battery.
Its actually not really new technology... Its been used to recharge electric toothbrushes forever.... They have just have improved it to the point where the coil that generates the magnetic change doesn't have to be inside of the coil that generates the electric current.
I think the huge challenge was using a small enough magnetic field that it doesn't interfere with other things, but still creates enough current in the induction coil...
Very cool though.
Edit:
Well, like I said I guess they just use a fairly weak magnetic field...Its not really the only consideration.mtb0minime wrote:

It depends on the geometry of the circuit, but when using a coiled wire is used to create a current it can be increased by increasing the number of loops in the coil... There is also an increase with the rate of change of the magnetic field IIRC...
Dunno if this is worth while to anyone else... but I found it interesting. Its an article from a physics book I have on wireless charging.

Gonna suck when you walk between the TV and the wall. :yikes:
Well, we'll have to say bye-bye to magnetic hard drives before this becomes reality....
The idea of any hi-fi system is to reproduce the source material as faithfully as possible, and to deliberately add distortion to everything you hear (due to amplifier deficiencies) because it sounds 'nice' is simply not high fidelity. If that is what you want to hear then there is no problem with that, but by adding so much additional material (by way of harmonics and intermodulation) you have a tailored sound system, not a hi-fi. - Rod Elliot, ESP
They couldn't figure that out before?blademaster wrote:

I want to know what the efficiency was to power that 60 watt lightbulb.
I read a while ago, not sure if it's this same project, but that one had an efficiency of about 40-45%. Yeah, 130W to run a 60W light... That sounds economical.Flaming_Maniac wrote:

Although, for smaller, less power-hungry things, like laptops and phones, it wouldn't be too bad.

At least the U.S. has energy problems, I would find it hard to justify doubling my power consumption on this kind of thing just to do without a cord/battery.Freezer7Pro wrote:

Sounds sweet.
The way that article was written was pretty slanted.
"Previous wireless power systems consisted basically of firing lightning bolts from sending to receiving units."
/sigh

I remember talking about this to a few people a while ago and we all knew it was just a matter of time before you could almost "wireless charge" ... this is the sort of technology that the world needs right now, not USB 3.020482
We're a generation of wireless, because wireless > wired (except on the whole web front at the minute)

That would be cool if my monitor could recharge my G7.The technology could also be built into plugged in computer components, such as monitors, to enable them to broadcast power to devices left on desks or carried into rooms, according to Smith.
DARN INTEL, stole my idea . back in '01 i thought of this (but for city wide) everyone said "I don't wanna be shocked when it rains". I tried and failed to explain that they would be fine . I didn't know any mechanics behind it (i.e. How to do it) but perhaps ill sue Intel... I told a teacher about my idea, and he has moved since '01. I cant find him
