Interesting talk/demo of WiTricity on TED. 10mins long.

http://www.ted.com/talks/eric_giler_demos_wireless_electricity.html

I can see great potential for this (phones, tv remotes, network devices, etc.) as well as the benifit of not having all those batteries being dumped.

Been watching this tech off and off for a bit now. Getting pretty close to real world usage.

thats pretty awesomeo

That is indeed awesome

oh wow he actually powered a tv with it, thought it was going to be pox

thats f***ing cool

interesting! my first question would be how robust is the field resonance to other external magnetic fields... especially ones that are resonating harmonically? still... cool if it works as planned.

yeah you're gonna have to explain that one to us lay people, demon.

ones that are resonating harmonically

Surely the TV/tuner would be a classic example of this? It would probably not resonate at the frequency required to interact with the witricity device. Just like hitting the right note to break a champagne glass won't break your TV screen as well.

Wireless Cancer!!!

Haha not wireless cancer bulls*** again. Did they ever prove that mobile phones give you cancer?

Nicola Tesla did this ages ago, on a large scale

yeah you're gonna have to explain that one to us lay people, demon.

just electromagnetic field interferance basically... there are lots of other electro-magnetic fields being generated by lots of electronic products. many products depend on harmonic resonance to boost thier outputs or perform other functions...so i was wondering if they would interfere, make one coil shift it's resonate frequency n shutdown the energy transfer.. or something :P just speculating as i have nfi how the actual mechanics of the device functions. i would imagine that thier boffins have considered this n have a solution... but time will tell for sure.

the dude in the vid says that nothing in nature would match the resonate frequency to interfere... but made no mention of other electronics.

Wireless Cancer!!!

why must all mutations be bad :( maybe it's just the right frequency to turn us all into x-men!@! ;p or not.

It already has in many cases,
See how many are psuedo "blobs" fat c***s who sit in front of their computers absorbing electricity (people still try an claim it's crap diet when we all really know the cause)?

Charlie Teo believes very strongly that mobile phones can cause brain cancer.

I'm pretty sure that as a practicing neurosurgeon he knows a lot more about brain cancer than you or I. He might be wrong, but I think that his opinion holds a lot of weight.

Yeah the theory is that the radiation is the wrong type to affect our cells. However once upon a time the light we consider to be visible didn't affect our cells either. Then we mutated on some eyes.

When I lived in perth several years ago, there was a big fiasco about some guy who created a massive transducer that literally soaked up the static electricity from the nearby power lines and he had free electricity for years. Western Power wanted to bill him for all the power used but they didn't have much of a legal footing as the guy didn't have an account with them and was essentially sucking power from the air.

Well, these things must work at a very specific frequency and the chances interference would be about the same as any other wireless technology I would imagine. That said, this isn’t going to be a big issue from what I've seen so far.

I like it, especially the electric car benefits. Strips of road could be made with these things built in to act as a fuel station where you don’t even have to stop. Nice.

Didnt mythbusters try and do this, I cant remember the outcome, but I dont think they could get it to work?

Found it Viper.

A free energy device can be made to harness enough energy to power a house.

busted

Free energy itself is a scientific fantasy. Almost all of the free energy devices the MythBusters built consumed more energy than they produced and the one ’successful’ device only produced enough electricity to power half a wrist watch, and was ridiculously large for such a small amount of energy. One test, cut for time and shown on "MythBusters Outtakes" involves coils of baling wire being used to siphon off electricity from nearby PG&E power lines in the Santa Cruz Mountains.

well if someone who makes a cable tv show couldn't get their homejob futuristic technology to work in the time it took to film a fraction of 1 episode, then I guess it's not possible

Yeah sounds like a good idea but the first question they will ask is "how can we charge people for this?".

Aren't Samsung working on a phone that will charge using radio waves or something? They reckon they will be able to get 10-20mA just off of loose microwaves.

We are in the Earth's magnetic field right now, I wonder what is involved in making this technology work in conjunction with the naturally occurring energy available.

How are they going to charge you for this wireless electricity? Will the product ever take off? It'd have to be a government initiative, because noone will want to build the station for free......

wasnt there an ep of kenny's world were they power there house from the gas from pig s***?
ala mad max 3...........

cancerous phones are a myth akin to phones blowing up service stations....

Yeah sounds like a good idea but the first question they will ask is "how can we charge people for this?".

They could just implement an e-tag system. No account, no recharge. Wouldnt be hard.

Wireless Cancer!!!

We'd all be dead if that was going to happen. You should have at least clicked the link, but I see what you did there.

Put it in roads and use electric cars.

Or with those new electric cars coming out with the swap battery and go idea (range 220ish km) just put them in highways/freeways

you could have the charging pad at intersections

also the lines on the road at intersections would change according to who's turn it is.

We should not care what doctors (or other people) believe, or what their opinions are. As a practicing neurosurgeon, he hopefully will have access to the latest research in his field, which we should care about. Unfortunately, doctors are prone to drawing false conclusions from their own anecdotal experience, just like everyone else.

If we look at the physiological basis for such claims about causality (made clear here), there isn't really any. There is no reason why the radiation emitted from phones should cause cancer.

But let's play it safe and do some research to see if there is something we're missing. There was a huge study performed in Europe, with over 400 000 people that showed mobile phone users had no elevated risk of cancers.

Even the article that hogfather linked to has a couple of experts in this area saying there is no convincing evidence that there is any link between mobile phone use and cancer. The one piece of evidence mentioned in that news story was not even peer reviewed, so we certainly should not draw any conclusions from it yet.

Overall, I'm not at all suggesting we shouldn't care about these issues. If one of my favorite and most used devices is causing me damage, I want to know about it. However, the evidence (and the consensus of researchers in the area) points towards there being nothing to be alarmed about. It certainly seems irresponsible of the media to be creating those alarmist sorts of stories, that are backed up by belief rather than evidence.

We should not care what doctors (or other people) believe, or what their opinions are

This is just a flat out silly statement. The layman has neither the background or the time to thoroughly evaluate the studies in a field.

This is why we go to experts for expert opinion.

This is exactly why I posted, because the "authority" that this neurosurgeon has makes people think he will know a lot about everything, which is not necessarily true.

He is an expert at brain surgery and most likely neurological disorder diagnosis. I doubt he is an expert in the area of cancer research, especially judging from his apparent lack of knowledge of the research in that area. You're making an assumption that because he is a brain surgeon, he has evaluated the studies in his field relating to the effects of mobile phone use. Unfortunately, this is an incorrect assumption to make.

Let me clarify what I wrote before: anyone from any profession can have crazy beliefs and opinions that are in no way substantiated by any evidence. As soon as a scientist/doctor/whoever says, "It is my belief..." or "It is my opinion..." there should be warning bells going off, and we really need to be careful about what they are saying next. This is especially true if they don't mention the impartial evidence for any such beliefs or opinion. If this neurosurgeon was saying, "It is my belief we need to operate on this brain tumor as soon as possible," I would trust him, because that is his area of expertise. But in this case he is talking about something that he not an expert in (as far as we know) - cancer research.

To exaggerate the example, the pope has said before that condoms INCREASE the risk of contracting HIV, and sadly, a lot of people trust him. But he is speaking outside his area of expertise, which he should not do.
