Sony Prototype Sends Electricity Through the Air
itwbennett writes "Sony announced Friday that it has developed a prototype power system based on magnetic resonance that can send 'a conventional 100 volt electricity supply over a distance of 50 centimeters to power a 22-inch LCD television.' Unfortunately, Sony's prototype wasted 1/5 of the power fed into it and additional losses 'occurred in circuitry connected to the secondary coil so the original 80 watts of power was cut by roughly a quarter to 60 watts once it had made its way through the system.'"
But if they can't improve on 50cm, I'm just getting a 2ft extension cord for fixed items.
(sorry for mixing units)
Arguing with an engineer is like wrestling a pig in the mud. After a while, you realize the engineer enjoys it.
globalwarming please?
seriously, wasting 1/5th of power just so you don't have to install some fucking wiring is just plain wrong. that's ignoring the fact that you will probably want to wire it up through hdmi anyway.
cocksuckers. one side of the tech business is actively thinking "hmmm fossil fuels will be running out, WTF are we gonna do" whilst the other side goes "WOOOOOOOOOO! Wireless power! PARTY ON!"
Where does that 'wasted' energy go?
If they were trained better, they could throw the power supply over a larger distance than merely 50 centimeters.

Why is anyone wasting any time on useless technology like this? Is it based on consumer demand? If so then consumers need some basic physics and electronics lessons. This is not Star Trek, people, we can't "beam" your power to you via subspace, the inverse-square law fully applies, this is not ever going to be efficient or practical! Electrically powered things require power cords, get over it!
Are YOU using the TOOL, or is the TOOL using YOU? Think about it!
I think this would be really neat if it wasn't limited to only sending electricity through air. Does anyone know what prevents this from working in a vacuum or through solid objects. Is the oxygen being magnetized or something?
Once again, slashdot catching up with old news and making one company in the lagging position look like the frontrunner of a new technology. Fast Company, among other places, have already published on the several research teams who've had operational prototypes for at least a year, and with comparable benefits, challenges, and ineffeciencies to the unit described in this summary.
See "Wireless Electricity Is Here, Seriously", Fast Company, Jan. 2009.

If this is a Sony technology, you better believe the electricity is going to be in some kind of proprietary format that requires you to purchase special electrons at a 30% premium over industry standard.
If libertarians are so opposed to effective government, why don't they all move to Somalia?
This is impressive efficiency.
50cm is still too short though, so let's see if the efficiency remains workable as distance increases (square law).
A TV is a stationary device. Why would you need wireless power for anything other than cosmetics? Wouldn't it just be better to put an outlet behind your wall mounting bracket?
I can see this in a parking spaces for electric cars, so you don't have cables running all over the parking lot of a mall. Or for small devices that don't need much power but would be a pain to power with batteries, like LED track lighting or security webcams or smoke detectors.
Big, rarely moved devices don't sound practical. after all, if your going to use this for a TV, why not a microwave or a fridge?
DNRTFA, but what happens if someone steps into the "beam"? BBQ anyone?

... it turns out that power can be transmitted wirelessly over long distances in a sufficiently efficient manner to power useful electronics!
Finally! I can power my pesky lightbulbs without having to physically wire them! Thanks Sony!
that is what i thought too. 80% efficient! Its not like wires are 100% efficient.
I'm more interested in this type of technology for charging all the various devices with batteries without having to have the right assortment of cables and adapters.
This is Sony.

No More Mr. Nice Guy!
Tesla was working on wireless electricity transmission but he was also working on a load of other stuff, all while baking his brain with "health-giving" X-rays. And while Tesla both claimed to have succeeded in wireless transmission and others are purported to have witnessed it, he never once made a claim as to the efficiency which, based on the efficiency of a lot of his other inventions (70% [RMS] for AC, >80% for a coil) was never higher than what Sony's come up with here.
if I placed it between the 2 units ? I'm not sure that I like the sound of that. Got kids, how long would they survive before being cooked ?

Duracell has invested millions of dollars in wireless power transmitters. These transmitters are about two and a half inches long (6.33 centimeters). One of the transmitters can put out 10 watt-hours, while another type can be daisy-chained to easily produce over 100 volts.
They're constantly improving the technology; Units are usually at least 75%-85% efficient. And they are not affected by the inverse-square law. It's pretty interesting stuff.
You'd be hard pressed to measure the line loss of a standard copper wire over two feet. It's probably like 99% efficient, if not higher.
great way to increase your carbon footprint, just to save 2 bucks for an extension cord!! BB
Umm I'm sorry, but when in Star Trek did they "beam" as a means of power transmission. Give me an episode reference or it didn't happen.
There will be consumer demand. Marketing departments come up with clever ways of making people think they NEED the new technology. Honestly how many people can actually tell the difference between RGB, YPbPr component and HDMI? or 6 HDMI ports in one TV, because more is better.

Those who can make you believe absurdities can make you commit atrocities. - Voltaire
Oh please, not this tripe again.
For one thing, your invention list is severely flawed. Many things which you say were invented by one group were actually invented by someone else and then developed or refined by another. The Japanese didn't invent hybrids; locomotive and heavy construction equipment makers have been using diesel-electric powertrains for decades.
You're also forgetting the Arabs and algebra and various other things (granted, this was back around 1000 AD, not recently when they've been too busy fighting with each other and everyone else to do anything productive).
A quick google search for "african inventions" yields the following website:
http://teacher.scholastic.com/activities/bhistory/inventors/
Did you know the carbon filament in light bulbs was invented by an African-American?
Or that peanut butter was invented by famous African-American George Washington Carver?
Garrett Morgan invented the gas mask and the first traffic signal.
Otis Boykin invented the pacemaker, among other electronic devices.
And Lonnie G. Johnson invented the all-important Super Soaker.
The reasons for the African continent's problems are explained in Jared Diamond's "Guns, Germs and Steel", and has a lot to do with geography making agriculture much easier in Europe than in Africa, causing Europe to develop faster technologically.
What have you invented? Probably nothing.
A typical lightweight power cord is 16 AWG. 60 Watts (assuming good power factor correction) is 0.5 A. 16 AWG wire is ~ 4 mOhm/ft. So 4 ft of wire (2 ft cord, supply and return) is 16 mOhm. That means you're losing 8 mV of your supply voltage, or 4 mW of power. That's about 99.993% efficient.
You have to get significantly longer extension cord and put a lot more current through it before the power loss is relevant. Even if you used a 12 ft cord, and drew a rather significant 4A, that's still only 1.5W out of 480, or 99.7% efficient. And most extension cords are 14 AWG or thicker.
That is excellent for wireless power considering my Tesla Coil has more than a 70% loss
Forget the Sony jokes for a minute. I can think of a great use for this technology : recharging smartphones!
Essentially, if they can miniaturize the receiver coils sufficiently enough, you could pack them so that they are integrated inside the batteries used in a smartphone. (yes, yes, it is somewhat inconvenient to swap the battery in certain Apple phones...)
Imagine the possibilities. You could have one of these transmitters in your car, plugged into the cigarette lighter and stuck between the driver's seat and the cupholders. Another could be on top of your nightstand in your bedroom, or wherever you tend to toss your keys, wallet, and phone at the end of the day. A third one would be in your office on your desk.
If the range is enough (100 centimeters or so) your phone would get recharged while it's still in your pocket! You'd never have to remember to plug it in, and you would be able to use the various power sucking features (games, turn by turn GPS, etc) all you wanted and would almost never run out of battery. It would neatly solve the battery problems with the current generation of smart-phones without having to make the phones bulkier or heavier.
Problems :
1. The receiver coil might take up too much space inside the phone.
2. The range might not be 100 centimeters due to various scaling laws
3. The electromagnetic charging fields might cause biological tissue damage, making it dangerous to use while in your pocket. It might interfere with pacemakers.
4. The fields might wipe credit cards or interfere with electronics in your car or office.
But if these problems aren't that bad, or can be avoided somehow, it would be great!
great idea! magnets and electronics always get along well
Nikola Tesla invented wireless electricity transfer at the turn of the 20th (yes, 20th) century. He was trying to prototype it by constructing what was called the Wardenclyffe Tower. Of course, everyone during that time thought he was a nut and the funding ran out.
Tesla is a candidate for the title of "smartest person who ever lived," and without him we probably would not have alternating current, which probably means we would get zapped much more often from our PCs (or "PMFs", i.e. Personal MainFrames). Now, considering the way society neglects its heroes of innovation, just watch Sony finish this and claim to have brought "wireless power" to the world, without ever having mentioned Tesla. "Oh yeah, him? Well we figured this out on our own. We just read a lot of these old books on magnetic resonance and pieced it all together. So smart is we!"
So I am not sure what the difference is between Sony's technology and Witricity (http://www.witricity.com/). To refresh, these were guys at MIT who discovered that magnetic resonance, instead of induction (used in toothbrush etc), can be used for quite efficient short distance power conversion. They quote getting > 90% at 1m through their system. This has also been demo-ed at TED and many other places. The question is, wasnt their technology (witricity) patented? If so, how did sony get to demo something so similar? if not, it would be interesting to know the difference.
Just two hints: population size and literacy rate.
This is impressive efficiency.
50cm is still too short though, so let's see if the efficiency remains workable as distance increases (square law).
IDK, according to a square law you could just move it farther away from the source to get more power
:-P
Now that I think about it, I'm pretty sure everything I just said is completely wrong.
Yeah, I wonder what the losses are if you charge the earth. Distance wouldn't matter then. Maybe we could build some wooden transmission towers near the generators at Niagara falls or something...
The cost of that cleanup, of course, will be borne by taxpayers, not industry.
"But I killed the galoot when he started to shoot electricity into my walls." Robert Service (The Ballad of Pious Pete is an excellent poem)
People have been demonstrating variations on this for over a century, since Tesla shorted out the city of Colorado Springs.
It's still largely a solution looking for a problem. There's some areas where this kind of thing is both safe and useful, but they're pretty specialized. Charging or powering personal electronics isn't one of those areas.
Fortunately this isn't using the same method, so there's no risk of charging the planet.
The cost of that cleanup, of course, will be borne by taxpayers, not industry.
"without him we probably would not have alternating current"
Just because something was invented first by someone, doesn't mean someone else wouldn't have figured it out later without them. That's like saying if Joe Caveman hadn't invented fire we would still be eating raw food.
Hmmm, let's see: "electricity through the air." Where have I heard that before? Oh, that's right. Lightning.
One "Aw, Shit!" is worth 100 "Ata boys!"
That is why this kind of technology _saves_ power. Yes, the TV is better off with the power cord. But the Roomba, your TV remote, and anything else that uses a battery, would save enormously by using this.
Let's do the math on a Roomba.
The latest Roombas uses $90 NiMh battery packs that store 3 ampHours at 14.4 Volts. I just had to replace some of mine. I estimate I got about 250 charge cycles out of them.
3 Amphours * 14.4 Volts = 43.2 watt hours * 1KwH/1000 Watts/Hour = 0.0432 Kwh is stored each cycle
0.0432 KwH * 250 cycles in useful life = 10.8 KwH in useful life
$90 / 10.8 KwH = $8.33 / KwH
The battery is imposing an additional storage cost of $8.33 per Kilowatt hour of electricity.
Contrasting wired power versus battery stored power (where electricity costs 20 cents per Kilowatt, which is what I pay), we get:
0.20 ($/KwH wired))/8.53($/KwH batery + electricity) = 0.023
In other words, the battery system is only 2.3% as cost efficient as the wired system. Or flip it around if you like, the battery system costs 42.65 times as much per KwH as the wired system.
Now comes along this wireless power system. It could lose 95% of the transmitted power, and it would still be twice as cost effective as the wired + battery system. For a Roomba, they do need to solve the 2 foot range, but they can give up a HUGE amount of efficiency and still destroy using a battery.
I neglected power cycle losses in the battery, because the wireless power is so stunningly better it doesn't really matter. If you included those losses, you would probably only need a 2% effective system to be cost effective with the battery.
The moral is that this is a great technology, but a TV is a lousy example. Anything that uses batteries is a great example.
All this "broadcasting power" stuff is not going to fly.
All the schemes that have been tried by Tesla and latecomers don't have a chance. Either they're spewing out energy, which goes down in intensity as the square of the distance, or they're like Sony, and making big air-core transformers, where the fields go down as the CUBE of the distance. You'll notice it takes a 40cm coil to send power 50cm. And so on.
Then there's the problem with all the scattered energy that does not end up in the receiving device. We're talking many watts of power. Microwave ovens are only allowed to leak a thousandth of a watt-- no national safety agency is going to allow ten thousand times that much power wandering around our houses. Yes, the power couples somewhat weakly to flesh, but it's still a lot of power to be bathing in 24/7.
Put this in the center of the roads, and power your electric vehicle without a huge battery bank required. Even more efficient because you won't have to be using electricity to haul around 500kg (or however much) of batteries.
Someday.
Tesla would be proud.
Even if one ignored all the rest of the bigoted idiocy in your post, you still forgot what they teach you in almost every first year research methods class: correlation does not imply causation. Furthermore, even though I'm sure you couldn't produce a peer reviewed study that backs up your asinine assertions, such a study would be asinine in and of itself because an IQ test is something that has been widely challenge in regards to legitimacy in gauging intelligence, and is highly culturally biased. Are you going to start talking about dianetics or eugenics next? Lets skip that and just ask for Obama's birth certificate already. I guess what I'm trying to say is, if you need to cling on to ethnicity or racial background for a sense of self, and allowing it to define you, you're basically stating that the most significant, most important thing about you is something you had absolutely no control over; yet it is more significant and more important than all of your life achievements. In conclusion, you're a tool.
Ive seen some posts about this being a rehash of Tesla's wireless power transfer scheme. This is false. While this technology was pioneered by Nikola Tesla, it is much older than his scheme for wireless power transfer. This is a tesla coil. A tesla coil, essentially, is two LC circuits resonant at the same frequency with magnetic coupling between the inductors. The impedance of an LC resonant circuit is given by sqrt(L/C). The resonant frequency is given by 1/(2*pi*sqrt(L*C)). The primary tank has more capacitance, while the secondary has more inductance. Because they are resonant at the same frequency, magnetic coupling transfers energy from the primary to the secondary. Because the secondary has much greater impedance than the primary, the same energy sloshing about in the secondary sloshes with much greater voltage and much lesser current. This 'technology' appears to work in much the same way. The only difference is that the ratio of primary impedance to secondary impedance is chosen so that the secondary voltage is suitable for the appliance being powered. Because the diameter of the coils is small relative to the wavelength of EM radiation at the resonant frequency, little energy is radiated. The inefficiency occurs because the resonant tanks circuits must have relatively high Q factor. Thus, the circulating currents are large compared to the real power transferred. Note that the resonant capacitors must be rated for very large rms current. Also this is [I]not[/I] 'magnetic' resonance. This is an air-core transformer with power factor correction!
I think that IQ, like money, tends to be a dividing factor between the haves and have nots.
Those who go to college tend to be prepared to get high enough paying jobs to make sure that their kids go to college, whereas the poor tend to stay poor since they can't afford to pass on the tradition of getting a degree.
Seeing as africans were once considered mere slaves, and thus excluded from the vast majority of societal benefits enjoyed by the white man, I'm not surprised that they're still crippled from ages of discrimination and slavery.
Kinda like how a fire doesn't spontaneously revive even if you let it dry from the bucket of water you poured on it.
Great some day I'll be able to leach electricity off of my neighbor's apartment just like WiFi!
Over at area 51, s-4 and other locations. We've had this for over 50 years, but the corprocracy chooses to not distribute it to us because they can make so much more money on oil and fossil fuels.
Don't believe me? Where is the multi-trillions of dollars spent on black projects going? On many flying vehcles that use this type of energy.
globalwarming please?
What warming? Seriously! We are on a downturn right now. Now that the climateaudit guys figured out that the famous "hockey stick graph" data was cherry picked, you have to wonder what all the hype is about.
cocksuckers. one side of the tech business is actively thinking "hmmm fossil fuels will be running out, WTF are we gonna do" whilst the other side goes "WOOOOOOOOOO! Wireless power! PARTY ON!"
Ummm. We have plenty of oil (highest levels since 2000). A friend of mine recently sent me this link: http://www.nytimes.com/2009/09/24/business/energy-environment/24oil.html?hp

What incredible bullshit!
It doesn't send electricity through the air. It sends energy through the air, which is converted from/to electricity at either end.
Saying that George Washington Carver invented peanut butter is selling him a bit short. His real achievement was promoting intelligent, chemically balanced crop rotation to the US South, which had been operating mostly on a brute force agricultural model, propped up by slave labor prior to that. Peanuts were just one of the soil restoring crops he promoted and peanut butter was just one of the products produced from them.
1 1/2 feet? Perfect, i see some applications for that. Imagine having a electric car, parking it somewhere, and having the parking spot automatically charge your car. No wires, nothing that can be stolen, because the device is under half a foot of steel enclosure.

is hardly enough distance to reach more than 2 shoulder-to-shoulder people in a crowd. the govt's gonna want better range, and probably higher wattage, before they consider this for crowd control.
"To stop the terrorists."
He also invented the polyphase AC motor (which powers pretty much the whole world) and the florescent light. Tesla is #1 on my list of people I would like to have met. It's really a shame that he had no business sense. Edison set us back years pushing his DC power system and claiming that Tesla's AC system was dangerous. Edison was an idiot and an asshole. Tesla was a true genius.
It will kill you instantly. Fortunately, it comes with a special rubber sheath and stand, which you can use to wrap around the beam, therefore making sure that you can see it and don't touch it.
Why do you think this has anything to do with Tesla? There is much more to electricity than even Tesla knew--and more than one way to transmit wireless power. Do you have any reason to think that out of all the different ways to do this, they are using the one Tesla experimented with?
No shit. This person is completely right.
First, I strongly doubt they'll get beyond 80-85%. Especially in realistic environments, where the coils aren't expectec to be perfectly aligned. Secondly, the provided example (a TV set, of all things: something which can be harmlessly and conveniently fed by a classical power cord, with perhaps 99.995% efficienc) just conveys this message "PARTY!".
Never forget, never forgive.

Other companies have done this before. One which comes to mind is an MIT startup called Witricity - I caught their demo at least a year ago in the news and even on the unsuccessful US TV show Brink. Witricity [http://www.witricity.com] site has a bunch of information on the technology.

MMO Quests are like orgasms:
You may solo them, I prefer them in a group.
Honestly does anyone here think that walking around passing through "POWER" emitting stations I'll call them is a good idea?
People have enough reservations with mobile phones and power lines over head.
I know, I have a great idea. I'll combine the mobile and the power line into wireless power. There is no way people will object.
Seriously people this is nuts. It's bad enough that the first desired usage is small devices and entertainment devices. Things that we literally put on our heads and near our crouches.
Lets take two steps into the future shall we.

Wireless power is now part of the land scape. It leaks only %5 now a vast improvement. I live a dream life where my toys are no longer burdened with the bulk of a battery. My phone is literally glued to my ear now. I have a flexable touch display wrapper around my left fore arm. I live in a geeks nirvana.
Ah but the flip side. The companies that make these devices are cutting corners to save money. One theing they no longer have to worry about is low power consumption. Because they can literally use as much as they like and not worry about how big the battery is.
So now our portable device have become power hungry machines. We have power broadcast stations everywhere. We are now walking around in a constant field of almost 1200 watts of broadcast em power.

Does any one else now see how this is a STUPID idea? This is not a case of I'm afraid of new tech. I'm afraid of DUMB tech. And this ranks up there with the over priced black and white Kindle that cost more than an netbook kinda DUMB.
The thing about IQ is that slightly less than 50% of the worlds population has an IQ of less than 100 ... (how many of them post on /. ?)
As simple LEDs use next to nothing in the way of power, why isn't it possible to make something that picks up WiFi energy and powers an LED with it? It's been a while since I played with radio (decades, actually), but it can't be that hard. If we're walking around in 1200 Watt of broadcast power of which 90% I personally didn't ask fr I think it may be fun to use it for other purposes.
A WiFi powered torch strikes as an interesting idea. As you can now get 1F capacitors you don't even need to be in the field all the time..

Most extension cords are actually 18 AWG. 16 AWG for the "heavy duty" variety. Good luck finding a 14 AWG extension cord anywhere except through a specialty store.
This is not only old, some people have been known to hyst power from overhead electric lines via coil in a barn. I'm not talking any sissy 100 volts, I'm talking enough to power a house. We went over this in physics class. Yawn Sony.
I used to idly wonder if there was any significance to difference in intelligence metrics amongst different cultures.
Then I found out that academics aren't even allowed to raise the question.
Even pursuing research tangentially related research that has the *potential* of reaching a politically incorrect conclusion is a career death sentence.
Enough so that no basic research has been done in years.
Ummm your pc actually runs of DC. That's what the power supply does it converts the AC to DC to run all those neat gadgets in your box.
I saw a demonstration of this from MIT students. I'm pretty sure sony bought it, not developed.

We know that African IQ is small than Japanese/European IQ by about 20 points. Can this large difference in IQ explain the gross failure of all societies dominated by Africans?
News Flash: Africans score lower on tests designed by...well..... Americans and Europeans than well....Americans and Europeans do.
If anything, African intelligence is stunted by poor nutrition from less than ideal agricultural conditions and spending more time worrying about survival than learning how to do logic problems. You can be assured that western societies would have problems if there was not enough usable soil to grow crops and raise animals. Ignoring these important factors to declare Africans intellectually inferior is just plain racism.
Does this come with WPA encryption so my neighbors can't use my wireless electricity? Or does it come with a "surge" button so I can fry whomever is illegally stealing my power?
there are plugs at both ends which can offer some resistance, probably more than the wire itself.
Have you ever even taken a course on human intelligence? "legitimacy in gauging intelligence"? Seriously? It`s true that creativity loses its correlation with intelligence after about 120, but your assertion that the results are "culturally biased" to such a degree that it accounts for the huge differences between Africans and other races is ridiculous. We`re talking about averages well below the 120 mark.
Furthermore, Obama is only half African American. Even more so, African Americans` IQ in the US is on average 10 points higher than those in Africa, most likely due to a long history of intermixing with whites.
And I`m really tired of hearing the `correlation does not equal causation` meme. Studies on IQ go to great lengths to control for external variables. Statistical methods are used to eliminate factors that skew results. Moreover, repeated findings of correlation between race and various attributes (which you would learn about if you took a class on human intelligence) can imply a relationship. Otherwise every freaking study every conducted would be unable to draw hypotheses based on correlative data.

Sorry, I was just going by the tiny bit of text on that site, which definitely didn't talk about all this. Thanks for the info.
Correlation does imply causation. It doesn't prove it. It doesn't tell you in which direction said causality acts (Does A cause B, or does B cause A), nor whether it's caused by some external unmeasured factor(s) (C causes A and B).
Pity you didn't make it to the second year of your community college course in kumbayology.

Furthermore, we're talking averages. I don't feel inferior to members of those races that (on average) score higher than whites[1], nor do I assume I'm automatically superior to members of those that (on average) score lower than us.
