hmm interesting but wouldnt there be a problem with the energy that it is expelling interfering with other electronical devices like bionic hearts and other artificial organs that are sensitive to electronic interferience?....and what about the cost of the electric bill..if it was on all the time t would run the bill up..and if you could turn it off and off wouldnt that kind of defeat the purpose of having it to provide power?

Wow yall are dumb.
I`ve built a tesla coil. This is a rip off from Nikola Tesla. They`re presenting it as new tecnology when it`s been around over 100 years.

a few things to address-
1) the frequency of the radiated energy will not allow you to be `electrocuted` in the classical sense. However, while most of the power should travel around your body (look up the `skin effect`) nasy RF burns are still possible.

For an "in home" application, this is really not nessicary. Tesla tried to implement a system to provide power across the atlantic, the Wardenclyffe tower was supposedly a giant tesla coil, but there was evidince that tesla was aiming at something much bigger.

And before anyone harps on about cancer and ionizing radiation and cancer they really ought to do their homework. Electrons can ionize atoms as well as light can.

If this has the kind of range they`re expecting, then the distance between the two sides of a loop in any electrical circuit will be negligible compared to the distance from the transmitting coil. When the feild is applied, currents will be induced in both sides of the loop simultaneously, but acting in opposing directions within the loop and the difference between the two will be negligible. The only way to make this feasible is by either moving the loop extremely close to the transmitter so that the loop size is large compared to the distance between the two, or increasing the loop size to get the same effect. I`m assuming people don`t want 6 feet long mobile phones for example and reducing the range to a usable one defeats the object as if it`s going to be placed a few centimetres away, then a simple contact arrangement as seen in a cordless phone charger housing would be far more efficient. For effective wireless electricity, you should just put a solar cell on your lamp.

Agreed extremely old tech, Nikola Tesla utilized variations of his "Air Core Transformer" more commonly known as a Tesla Coil, to create the same effect. These did not throw of the sparks like his other versions. As for neighbors stealing it, if small ones are utilized the range is extremely limited, or of course you could always turn the house into a faraday cage, which would add some cost to construction but not exorbinate. As for the field interaction with living creatures, well there hasn`t been a lot of study there. All in all its an interesting use of Tesla`s work. I have a feeling the "breakthrough" line was used by the paper to catch the readers attention, I seriously doubt the Dr. used that wording.

I`d stick with Tesla`s stuff, works better.

No reason to stop with praising Tesla`s more efficient and effective ideas, you don`t seem to stop with your pointless rants.

They`ve also made leaps in transferring energy by waves on the light spectrum, kind of like IR, except power.

-an the way people would get charged will probably work like wifi. You pay for a certain amount to be broadcast over a certain space. And if you want to charge people using it, then the machine they`re using will identify itself when using the power (again like wifi).

Oh yes,

Not necessarily, because these waves will not be as absorbed as other types.
And the only reason people are dying from cancer is because we are fighting off almost every disease, and people need to die somehow.

If any, very slightly, and that`s only in apartments. The range dies at about 9 feet. So no. they most likely would not.

Isn`t that why they are developing cheaper ways to produce electrical energy??

Heaven forbid if people actually attempt to READ things =O.

"Won`t you be electrocuted?"
No. It is an EMF with modification so that anything not programmed to does not absorb them.

"Didn`t Tesla come up with the same idea?"
Yes. The writer says this theory/idea/whatever hs been around for centuries, he just modified so it was not dangerous in a house.

Next time, try actually reading the god damn thing before you post, dippoos.

Sure, Tesla had the same sort of idea. But he had a couple of big problems. First, Tesla coils are really loud. Second they can be kind of dangerous due to the high voltage. Third.. and perhaps more important..you can`t make money off it. If you broadcast power for free over large areas, ( think wi-fi) how are you going to make money charging people for electricity of you can get it for free? But they sure are cool to watch....zap!

Uhhh...kinda cool, but doesn`t that mean that all the lights in your room would be on as long as that thing is on? Considering you turn them off by breaking the connection through the wire....you can`t really do that with this thing. I guess you could turn the thing off, but then you wouldn`t be able to power anything at all.

Ok, stop with the Nikola Tesla. Yes he had a similar idea, the article even says it`s an old idea. The difference is the refinements they`ve built into it.

Surprised you`re not sitting there going "What? Energy without wires?! Grugmug the caveman came up with this in 8000BC, it`s called FIRE people! Why is this new?!"

Reading through the article again, (and the one in Gulf news), I`m still not seeing how they`re getting 45% efficiency.

"The concept of sending power wirelessly isn`t new, but it`s widescale use has been dismissed as inefficient because EM energy ... would radiate in all directions. Last Autumn though Soljacic explained how to do the power transfer with specially tuned waves".

To me that`s not equating to 45% efficient. (By the way, the receivers are currently 2 feet wide).

The article seems to be suggesting that power transformers work using electromagnetic radiation, which is odd seeing as they don`t.

This is a well established concept, but I`m surprised it works over such distances. It must also make a pretty powerful field, or employ some form of physics that I`m not privy to.

Btw, it wouldn`t be terribly harmful since it`s not all different from the magnetic field that the Earth generates (somehow), whose deflection of cosmic rays is rather useful for the function of living things.

I wonder if the magnetic field would deflect the rays of our beloved wireless networks? Or maybe use it to levitate your keys, erase the magnetic strip and chip on your credit card and electrocute your tooth fillings?

it wont cause cancer... there is already electricity all around you its called flaux... basicly the same forces from a magnet.. put curent through a coil of wire and u get the flaux put another coil in that flaux field and it generates a current (wireless electricity) ever see a tesla coil (not the one from red alert that zaps and kills people) but the real thing.. big coil huge amount of power bring a light bulb near it and it glows.. ya thats basicly what this is.. nicoli (sp) tesla tried to do it hundreds of years ago but it never worked because it took way to much energy. this is nothing new. and no it wouldnt electrocute you when ur in the bath tub the coil would be insulated so the onlyway to transfer the electricity wirelessly would be to a coil of wire.. it wont go into the water.. enless u have a coil of un insulated wire in the tub with you.

It works also by using resonant frequencies (the same thing that made the millenium bridge in London wobble.

This from the BBC News website:

"1: Power from mains to antenna, which is made of copper
2: Antenna resonates at a frequency of 6.4MHz, emitting electromagnetic waves
3: `Tails` of energy from antenna `tunnel` up to 5m (16.4ft)
4: Electricity picked up by laptop`s antenna, which must also be resonating at 6.4MHz. Energy used to re-charge device
5: Energy not transferred to laptop re-absorbed by source antenna. People/other objects not affected as not resonating at 6.4MHz."

It`s like how when you can break a glass with sound. The sound must reach the same frequency as the resonant frequency of the glass before it will break. The sound doesn`t break anything but the glass, and this would be the same principal, but with magnetic fields and such.

I`ve always wondered about this. But, wouldn`t the waves traveling through the air harm you? Maybe not immediate damage, but think about the long term effects, if you had electric waves traveling through your body 24/7.

, (a reverse of what happened to the first coil), in to a wire, so you can use it.

For all the people who doubt the concept that this works on, (conductivity quotient, wtf!), look up `inductance` on howstuffworks. We`re not talking about zapping pure electricity through the air, we`re talking about magnetic fields, which pass thru everything, including people, more or less, without hindrance and without any affect to non-metalic objects.

A coil which is fed with elctricity, from a wire, spews out an electromagnetic field,like this. . This field, if stable, exists quite comfortably (in this case filling a whole room), not interracting with anything, for as long as you feed the coil with electricity.

But if the magnetic field interacts with another metal coil u bring in to the room, this new coil will draw some of the energy from the field--- If u feed a coil with a magnetic field, it spews electricity back out, (a reverse of what happened to the fi

Yeah, and then we`ll transform a chair into something weightless and teleport it through air =D. Seriously... why is it that anyone believes anything on the internet? Anyone with a college-level knowledge of physics would understand why this won`t work. Nature has already come up with a way of wireless electricity of it`s own: Thunderstorms. Human body has a better conductivity quotient than oxygen, so... electricity would much easier go through the human body than it would through the air in your house.

I don`t think people understand how tension is lost when an electric field is created. You can have an electric field throug point A and point B, but all electric waves would go through everything standing in between A and B.


And even if they manage to turn electricity into some unknown form of energy, easy to transmit through air, you`ll still have to plug something into electric devices to transform it back to electricity :)

after just reading a lot on that subject i can say that for sure you wont get electrocuted. They did not light up the lightbulb just like that with electricity thru the air. What they did is: using a coil, convert deadly electricity to something safe. send those harmless wave thru the air. Those wave hit a coil that convert it back to electricity. That electricity is sent to the lightbulb that is physicly wired to the receiving coil.

So as long as you don`t connect the receiver to the bath, the electricity will not be wirelessly sent to the bath.

This doesn`t fill your house with raw electricity, shooting lightning around your house like the tesla coils from Red Alert. It`s converting the electricity into a different form of energy.

Sort of like a lightbulb changes the electricity into light, you`re not going to be electrocuted in the bath by the light coming from the bulb just because it`s an "electric" lightbulb.

As for stealing, it depends how they do it but, they`re saying it has a 9 ft range, not the ~100ft range of wifi transmitters.

Also, think about exactly what they`re stealing when they log on to your wireless network. If this is continuously pumping out a static amount of energy, all they`re doing is using the waste surely?

I.e. If the neighbours are listening to your radio through the walls, they are not stealing your sound. Your bills don`t go up, it doesn`t get quieter for you.

I`ve always doubted this possible, but since WiFi, I`ve been wondering if it were actually ossible, moreso hoping though, and this is a sure sign it`s possible, but a lot of stuff would have to change. Not as simple as they make it. A lot of electrical goods would become redundant. Which says abd things for my expensive synths and workstation. I mean, I wouldn`t trust electricity wandering through the air either. It could react to anything, it could be a health risk of some sort, and mopreso it`d fry most circuit boards unless this `non radiative` electricity doesn`t do that, but electricity is electricity...

It is indeed amazing, that electricty can be passed in a large distance, but the downside is that you waste a lot of that energy from those waves not reaching its target.

It`s a good idea (cables ftl), but it might take a few more decades before they can make it optimum.
