It's not voodoo -- Intel's just showing off its wireless power transmission system at its IDF conference. The system could be worked into Intel's upcoming chipsets.  (Source: geekzone.co.nz)
Intel rounds off its developers forum with a wild new upcoming tech

Wireless is one of those hot tech catch-alls of the new millennium.  There's wireless broadcasters and receivers, utilizing such technology as WiMax, 802.11n, and Bluetooth.  There's wireless gaming controllers.  There's just about wireless everything -- except power transmission.

Wireless power transmission is something that inventor Nikolai Tesla came up with over a century ago and claimed to have perfected.  However, his mysterious work vanished with his death, and for decades the topic was left untouched.  Now there has been a resurgence in interest with several companies competing to becoming the first to offer commercially broadcast wireless power.

At the Intel Developers Forum (IDF) this month, Intel demoed just such a system.  Using two large coils it showcased a system that could send 60 watts of power at 75 percent efficiency up to 3 feet.  The power was enough to light up a bulb at the receiving end.

Justin Rattner, Intel’s chief technology officer describes, "Something like this technology could be embedded in tables and work surfaces, so as soon as you put down an appropriately equipped device it would immediately begin drawing power."

A computer-powering desk is just what Intel is cooking up in fact.  It says a desk with embedded transmission equipment could power laptops and eliminate the need for messy cables and proprietary connectors.

The new tech was first developed by Massachusetts Institute of Technology physicist Marin Soljacic.  Professor Soljacic came up with the idea of transmitting wireless power via resonant magnetic fields.  He calls the invention WiTricity, a blend of the words wireless and electricity.  The work relies heavily on the electric concept of induction.  Induction is already used commercially on a limited scale, to recharge certain powered toothbrushes.

Intel helped improve upon MIT's design, bringing the efficiency up from 50 percent to 75 percent.  Internally, Intel is speculating that the device may permit and work with the shift from batteries to supercapacitors.  While currently more expensive, supercapacitors could allow faster recharging. Mr. Rattner states, "In the future, your kitchen counters might do it.  You’d just drop your espresso maker down on them and you would never have to plug it in."

Intel calls its new technology a "wireless resonant energy link".  It uses transmitting loop antennas, less than 2 feet in diameter.

It is competing with a couple scrappy startups, who are also looking to improve upon MIT's technology.  Startups WildCharge, based in Boulder, Colo., and WiPower, based in Altamonte Springs, Fla. both are looking to make their name in wireless power history.  While both have announced consumer devices based on their upcoming technologies, their devices currently require the item to be touching the transmitter.

The advantage of Intel's device is it can transmit power even when not in contact.  And the receiver antenna is about the size of a laptop base, Intel researchers note.  Joshua R. Smith, an Intel researcher at a company laboratory in Seattle who is leading the project, states, "From Intel’s position that seems like the thing to shoot for right now.  It could be that cellphones and P.D.A.’s are even more compelling, but I think we are going to start with the laptop. It’s easy to dial down from laptops."

Mr. Smith also demoed how the technology could improve the field of robotics.  Sensors using the power transmission and reception technologies could use electric fields to detect objects, similar to how some fish detect objects in water.  In a demo the robot used these sensors to neatly grasp an apple, which it then loyally delivered to a waiting human hand.

Intel, according to Mr. Smith, will be developing a prototype of transmission system for laptops, which may be added to upcoming chipsets.  Thus, the next generation of laptops may be cord free.

Phil Hartmann left us too soon.

As for wireless energy, it's apparently only safe with DC power. It's easy to turn AC into DC but not the other way around. So unless every appliance changes to DC, we're not going to see our homes go wireless for a while. Something like this would be excellent for mobile devices though. Imagine batteryless cordless phones and laptops. There were also plans on using this technology on a large scale with microwave power which uses satellites to collect solar energy and beam it wirelessly to Earth.

Uhh...actually, there are plenty of DC to AC converters out there. Here's a good schematic: http://www.i4at.org/lib2/inverter.htm
Two transistors, two capacitors, two diodes, a few resistors, and a transformer.
AC to DC requires:
4 diodes (or a rectifier, which is basically just 4 diodes), some resistors, two capacitors, a transformer, and a voltage regulator (if you want really clean DC).

Realistically, DC power is AC power that has had its negative voltage flipped to positive, and then cleaned up through the use of a capacitor. If you look at it with a high sensitivity oscilloscope to can see the peaks and valleys, except that it looks like a saw rather than a sin wave.

While it is relatively easy to convert AC to DC, its can also be quite inefficient. The power lost during the conversion is why our wall warts and laptop power bricks get hot. As more of our appliances these days use DC it only makes sense to consolidate the conversion hardware into a higher efficiency centralized unit that could power all DC devices, rather than the multitude of lower efficiency wall warts we currently use.

As for Solar Power Satellites, that's a rather different and better proven technology. It uses the same phenomenon that causes metal objects in a microwave oven to produce sparks. The electromagnetic energy of the microwave photons hitting metal is transduced into electrical energy. The microwave beam can be focused enough that it remains efficient over the distance from orbit to Earth.

The technology the article discusses uses magnetic fields rather than electromagnetic photons as the carrier, and as a field cannot be highly focused like a microwave beam, its efficiency decreases dramatically as the distance is increased.

Actually most appliances do run on DC... You know appliances with those big square boxes at the plugs... they are for transforming the voltage down and converting to DC so the appliance can run, they put them on the outside to save room in the actual appliance. And appliances that don't have these, usually have them built in... Your computer runs on DC, as do most electronics, so its not really a huge deal...

The Intel wireless power demonstration uses AC to transmit AC, there is no DC involved in the transmission. DC current does not create the changing current, which creates the changing magnetic field, which is necessary for wireless power transmission. Also, the Intel system is using magnetic induction whereas the Soljacic system is using electrostatic induction. Soljacic's system will transmit power further if the entire room is inside a Faraday cage. I know, because I have built such a system in 2002. Tesla's system used magnetic induction only inside of the transmitter. For his wireless power broadcasting outside of the transmitter room, Tesla utilized electrostatic induction by modulating the Earth's electrostatic field.

As for the health effects, I have done experiments with this, too. Last winter I developed athersclerosis and found that strong electrostatic and electromagnetic fields induced panic attacks. There is scientific evidence verifying that even static magnetic fields can affect blood flow rate. So if a person has weak health due to restricted blood flow, a magnetic field could be a catalyst for heart attack or stroke. Of course, the best thing to do is clean out the arteries rather than try to eliminate all magnetic fields, which I did using enzymes.

Whether the system uses electrostatic or electromagnetic induction, the frequency could also have a negative effect on the health. While suffering from athersclerosis, I discovered the 29 khz frequency of the plasma ball I kept in my house was messing around with arteries by causing vasodilation. Although vasodilation is the opening of arteries, the plasma ball was apparently opening the arteries to allow more plaque to build up, and then when I left the room, the arteries would contract and cause blood flow restriction.

So there are some serious side effects that need to be dealt with regarding this technology before it should be put into widespread use.

Two curiosities: Efficiency and Safety.

Is it equally or more efficient than wired transmission?
Is it safe (and how do you identify the path of transmission / prevent objects and living things from entering it)? Clearly talking about when this tech is used on a larger scale and not just 3 feet where you can easily see the space where the transmission must be taking place.

Thanks Jay
I was thinking about the safety thing as well.
I don't know how many people out there have read many of the works by Robert Heinlein, an engineer turned writer in the 40's (invented things like the water bed, and the idea for moving sidewalks - slidewalks) but he wrote about transmitted power indirectly in one of his books.

I wonder what this may do to peoples' nervous systems. Our nerves weren't mean to be subjected to this continuously. And I'm not just worried about larger distances. What will the radiant energy do to peoples' other organs and systems.... say the ones under the edge of the desk where the transmitter would be?

I just think that personally, I would like to see a little research before I decide to subject myself to this kind of thing.

Im sure the intended purpose would be short range transmission for applications like charging a laptop, powering a desktop. Then other small things such as desktop lamps etc.

As for efficiency, well if it has to go through whatever system of transmission to become wireless then back again to be received, it isn't going to be very efficient. Instead of looking at this in a 75% efficiency, look at it as running at a 25% inefficiency. And id think they'd struggle to get past 85% efficiency.

Interesting tech all the same.

Intel is just blowing smoke 75% efficiency with parallel coils is not a big deal. But the second you rotate them relative to each other the induced current is going to be reduced by a factor of the cosine of the angle between them, not to mention the fact that the field reduces in power by the distance squared, and the field is further reduced if you are off axis. So you achieve 75% efficiency you have to be standing within 3 feet of one of two ends of a large powerful magnetic field. This is not useful, and will never be useful. I don't know if Intel thinks its at a high school science fair, but this is never going to be used.

Tesla was a true genius.. Thru and thru..
I have a book of his patents, which are easy enough to make at home with enough wire, and powerful enough to make you electric bill really high. He is one of the reasons we use AC current instead of DC, which Edison pushed.

Tesla was a big fan of magnetic flux and electric fields.. He demonstrated this idea in 1891 by lighting up vacuum tubes in his lab. He also was able to light bulbs by sending currents thru the earth from 100's of feet away.

If I could hang out with a inventor for a month, it would probably be Tesla, even over Da Vinci..

That is quite a statement and one I strongly disagree with. According to the article, the first practical application of the technology that Intel intends to pursue is building it into tabletops to power laptops. The distance between the supply coils in the table and the receiving coils in the laptop would be mere centimeters apart so that falloff of the field strength is not an issue. Since it also lays flat on the surface, or even at a small angle if the back is elevated, the coils remain close to parallel so that is also not an issue.

If you think that simply eliminating the cord from the laptop to an outlet is no big deal, tell that to my clients in the computer and audio visual rental business who constantly complain about how ugly the cables look and how much time it takes to properly conceal them or indeed have to run a temporary power infrastructure to power 200 laptops in a hotel ballroom with taped down lines run all over the place. I can almost guarantee that hotels that host many corporate events will be the first major customer for tables using this technology.

As for powering a light bulb from a distance of three feet, that is merely a better visualization of the technology for demonstration purposes, and as you say, not particularly useful for a practical application.

Not when the wires are thin or the distances long. #28 wire driving a 1 ohm load at 15 feet is going to have losses of 50%. Even our normal power-distribution lines have losses of ~7% in delivering power from the generator.

If you want to transmit power using #28 wire (barely bigger than #30 really thin wire-wrap wire), just boost the system's voltage. transmit a few KV over that #28 wire and the power efficiency should be a LOT better than wireless over 15 feet (and a transformer for AC or a switcher for DC be used at the receive end as appropriate to the application with good efficiency).

P.S. - The photo has the load 75W bulb look to be a standard 120V/75W one. If so, then it's operating equivalent resistance is about 192 ohms. If a one ohm wire were to be put in series with it to it's power source, it would not be consuming the 25W the wireless setup is (to yield a system efficiency of 75%). Less than 1W. And with less tiny wire much less than that.

Induction current. It's Physics 101.

This is how farmers used to steal electricity years ago. They ran a power line for their equipment parallel to the utility line.

Put a pot on the coil and you can cook your food too. There already exist induction ranges for cooking surfaces. You just need to use a resistive metal pan like steel or aluminum.

Induction furnaces have been used in industry for years and years.

That's the only drawback I can see with this. Heat. If you have such a coil on a desk or table, do not put any metal objects on it or else they will get very very hot.

GM also used induction for charging the Impact / EV1 with the "paddle."

The technology does seem sell suited for that application, and will probably find a niche market, but I think that a cost/benefit analysis wouldn't survive through bureaucracies into widespread adoption.

Governments looking to provide public curb side plug-in hybrid power wont pay for planting coils in the middle of parking spaces instead of just trenching along the curb and running lines and outlets.

Car manufacturers wont want to add additional weight and cost to cars that need to be as efficient and affordable as possible. Even to provide it as an available option there would be costs associated with designing compatibility into the basic models for a feature with an untested market.

Standardization would also be a significant bureaucratic obstacle.

The only market I think would exist is as an aftermarket luxury upgrade using proprietary equipment for personal or business use.

I would imagine this technology will be limited to powering devices up to a couple of feet away from the source for some time to come. Beyond that distance I would imagine that efficiency would drop dramatically. Also, what effect will it have on living organisms that reside between the transmitter and receiver, ie. you shouldn't hang out near cell towers because of the radiation risk. I have no doubt in the technology actually working, but will it be safe and efficient?

I like how the say Tesla made an perfected it. But Oh, BTW we just invented it now and heres how. LOL His-story at work.

This Tech has been suppress for years!!!! That why we can't get more 50hr battery life on laptops! We could have had this YEARS AGO!!!! Oh and you CAN bet this will help give you cancer...While talking on Microwave cancer phone and eating you GMO cancer burger!!!

nice from intel and yes interesting...

but if free electricity is something we all have some nirvana for, then sadly corperate business will put paid to that.

Nothing is free because imo we would all have free fuel for cars,bikes and planes etc.

The real use of this

I really see a tremendous use for this tech if employed to move solar/wind generated energy from deserts into power grids of metropolitan areas. Of course most of Tesla's work was classified by the military for incorporation into directed energy weapons. Can you say death ray!




To address the many misconceptions:

This is not induction. This is coupling via resonant magnetic field. It works as well as it does because little power / energy is transmitted to anywhere besides the complementary resonant coil. I don't profess to know much about this topic but the general idea is that the presence of a second resonating antenna modifies the innate characteristics of the medium that exists between the two antennas allowing for power transmission only between antennas over a small frequency band. For the majority of antennas this effect is treated as undesirable or neglected entirely because of the distance of transmission. The basic off-axis cosin and 1/r^2 relationships for induction do not directly apply. Also power does not need to be "sent back" over the link in order to complete a circuit. Do you need to "send back" the radio waves intercepted by your car antenna? Unless your body looks like a MHz microwave resonant antenna there will fail to be transmission of power. This is very different from a cell phone antenna that is always radiating power, essentially free space is its complementary resonant coil and your brain can and will absorb a certain tiny portion of that output. Please anyone correct me if I am wrong.

I guess this solves the problem with powering cybernetic organisms. We should install this in a T-800.

I really expected a picture of "The Prestige" in the picture there.




Hello surround sound speakers!

Yay, I don't have to climb into my attic to get surround sound speakers powered/driven.

Wireless data + wireless power = surround sound bliss




Nikola and not "Nikolai"

It would be nice for an author writing such article to use proper name of the father of alternating current system - Nikola Tesla.




Application?

I dare intel to put a HDD in the gap between (or indeed even the other side of) those 2 coils. Use the "beamed power" to drive the HDD and lets see how well that baby will record and restore data. LOL

EVERYTHING OLD IS NEW AGAIN




Here's An Idea:
By Quiescent on 8/24/2008 8:17:56 PM , Rating: 2
I was watching the show about Tesla and his inventions. I saw a guy in the same room with a miniature Tesla and powered a fluorescent light while holding it.

However, this means there is a lot of electricity in the air. People who use electronics to keep them alive will certainly not live under these conditions.

Then you have Electromagnetic Interference, which I experience on a rainy day. My EeePC is pretty good at getting these next to nothing wifi signals, and on a rainy day, it's very hard to stay connected to these wifi signals.

An example of EMI is when you have a MicroATX case with all your computer components jammed in. That constant static you hear on your speakers or headphones even when nothing is playing is EMI. When you hear odd noises on your headphones or speakers that sound like it is ticking to what ever it is that is using CPU load, that's EMI. The closer you have electronic components near your soundcard, the more likely you will hear static, I can hear it at every volume level on my EeePC, but in my Mid ATX case with an Audigy 2 ZS soundcard, I can only hear it at high levels of volume. Now imagine that everywhere on everything.

We need to have a wireless electric type deal that operates on it's own frequencies and does not interfere with ANYTHING. This will be the only time that it would be perfected.

But the idea is great. I think if Tesla was to be reborn again, he would still be a genius and reperfect his work, today.




Good to See

Maybe Intel can see that their company is nothing without a power source and with Energy prices going up and Energy getting harder to generate sustainably the old fashion way we finally see a shift toward cheap/free energy solutions.

The "cell phones will give you cancer" folks will have a field day with this
