Ok,going to look at your link,but it would have been nice if you add some more content from it and some of your own comments

So this is what you are referring to..........

A mobile phone that charges in your pocket, a flat-screen TV that needs no power cord, a car fueled by a cordless panel in the floor: In a nondescript building just outside Boston, these and other applications of wireless electricity signal a future with fewer snaking cables. WiTricity, a company spun off from research at the Massachusetts Institute of Technology (MIT), aims to redefine how people use energy, making it possible to power devices without ever plugging them into an outlet. In WiTricity's lab, various devices run on power transmitted via electric coils through the air. Plugged In, Virtually "It is not hard to imagine that in the next few years, you go to a coffee shop, sit down in a chair, sign into a power zone, and charge your phone or laptop," said Richard Martin, editorial director for Pike, a market research group that focuses on smart-energy solutions. "We predict this technology taking off in a similar fashion to how Wi-Fi got its start a decade or so ago." Martin says the industrial potential for wireless power is huge, especially in the realm of electric vehicles and wireless sensors, where harsh environments make it difficult to run wiring. In addition, he says wire-free electricity transmission is often a more convenient, greener alternative to conventional plug-in charging. (See related blog post: "Wireless Power Can't Yet Replace Utility Poles, but Could Offer More Options for Electronic Charging") "Part of this is that there is an obviously big space in the market waiting to be filled," Martin said.

You make good points, I should add more comments and add text snippets



Iam alas shy here on ATS.

Wow what an experience, it is true sometimes there are short circuits to conductive areas that should be fully insulatd from a power source.
This wireless technology sounds very good and safe though.
It is interesting as it says their technology see liink....is 100 times safer than mobile phone.

Where do you live and what kind of safety codes do you have? I suspect that the codes are lacking where you are for safety.

It's ok.
We are all the same on here,some have more power with words than others.
But that's all.Just words.

He lives in Vancouver somewhere.... freaky stuff.

I'm also curious about the safety of this...

WiTricity is a rather neat near-field trick using magnetic fields. It probably isn't an issue for health. It's not very efficient though. And yeah, you're going to have a low-power diathermy machine charging your stuff, but people use those all the time. It OUGHT to be safe. Probably.

And to think the scientific community called Tesla mad for his ideas on the wireless transfer of electricity. Well looks like he was right regarding its viability after all. The man was truly ahead of his time.

Except Tesla was into e-field transfer. This isn't. No Tesla coils, no radio waves. Not even radiating EM at all. Just near field stuff.

Excuse me, but Tesla was a pioneer in the field of resonant inductive coupling and a Tesla Coil, while capable of electrical discharges, is actually, at its heart, a resonant transformer. Don't just write off his contributions like that.

Overhead power lines = cancer.
Buried power lines = electrocution.

Oh, the irony.

So essentially a couple of posers sat down, and started decoding Tesla's confiscated documents. How nice...Not only did it take them about a 100 years, but they will likely even charge for it...What nice guys....

Um... isn't it amperage that kills? Not voltage? If the amperage is low, 10 000 volts wont kill you. If you are going to make a legal claim, you might want to make sure you do your homework. Here is a link explaining all this. Amperage Kills Not Voltage

It is the voltage that helps the amps to flow, you need both for it to be lethal. I could touch a 12V battery that can supply 1 million amps and nothing will happen! I could touch 100KV at 1nano amp and nothing will happen. Its when you have both voltage and current that it can kill. 110V is not as bad as 240V, I have touched the two with the tips of my fingers on one hand, voltage does help get the current through.

As for magnetic power transfer, I think its a bad idea. The reason being that metal in the area will absorb at least some of the magnetic flux and heat up, I don't want my glasses frames to start heating up, nor my fillings. It could also induce stray voltages in other electronics.

Possibly. I'm not that concerned about low power radio signals in the air, but transmitting higher power levels concerns me more. One thing we discovered with technicians in the military working close to microwave transmitters is that exposing them to higher power levels increased their risk of developing cataracts.

The effects of EM radiation on human tissue are not well understood, and being studied. The precautionary principle would suggest that we probably shouldn't make ourselves guinea pigs to find out what the effects of higher power levels on living tissue are, until the research progresses further.

However that said, I suspect if you plug in one of these wireless battery pack rechargers and put it in some un-used corner of your house, the risk to humans is pretty low. If however you put it on your desk close to where you work, I'm not so sure.
