Eric Giler demos wireless electricity

http://www.ted.com Eric Giler wants to untangle our wired lives with cable-free electric power. Here, he covers what this sci-fi tech offers, and demos MIT's breakthrough version, WiTricity -- a near-to-market invention that may soon recharge your cell phone, car, pacemaker.

TEDTalks is a daily video podcast of the best talks and performances from the TED Conference, where the world's leading thinkers and doers give the talk of their lives in 18 minutes. Featured speakers have included Al Gore on climate change, Philippe Starck on design, Jill Bolte Taylor on observing her own stroke, Nicholas Negroponte on One Laptop per Child, Jane Goodall on chimpanzees, Bill Gates on malaria and mosquitoes, Pattie Maes on the "Sixth Sense" wearable tech, and "Lost" producer JJ Abrams on the allure of mystery. TED stands for Technology, Entertainment, Design, and TEDTalks cover these topics as well as science, business, development and the arts. Closed captions and translated subtitles in a variety of languages are now available on TED.com, at http://www.ted.com/translate.

does some one know the efficiency of this mode of power transfer.... like how much of electricity dissipated is actually used...?

do we still have to switch it on and off to save electricity ....

i want this in my house now! When does the WiTri fantasy become reality?

[phenomenon91]

Wow he's nervous!

[leonidasx666]

This is amazing and I have no idea why this hasen't been widely implemented yet.

[lifemetall]

@elmstfreddie well OFC many haven't seen it before, we aren't all electricians.Reason why this is starting to be used now is because creators of these devices started ignoring the fact that coil wireless transfer has enormous loses in power to effectiveness ratio.. I strongly appose this because this is not what nikola tesla had in mind when he said "one day electricity will be transferred wirelessly", if we accept this we will stop working towards REAL wireless transfer

[elmstfreddie]

@lifemetall Yes I am well aware of transformers and their function. If this is so uncreative, why is it the first time I've seen it being used for wireless technology? And yeah argue all you want that technically they already work that way, but what I saw in this video was a new use of transformers I've personally never seen before and I'm sure many others haven't.

[lifemetall]

@elmstfreddie no, your comparison is wrong. I would bitch if someone would reintroduce ham sandwich as an original idea. And this is NOT a theory and the USE of it isn't new either, Opening most devices you will find the use of coils in a device called transformer, mobile phone chargers work on that principle for example

[elmstfreddie]

Don't the two coils need to be lined up in order to conduct to each other? Wouldn't that make this technology basically pointless except for static hardware such as desktop PCs or parked cars?

[elmstfreddie]

@lifemetall The theories aren't new but the use of it are. Like, you wouldn't bitch about BLT sandwiches because ham sandwiches already existed.

@hydrolito Lightning strikes for such a short amount of time... it's like having a water pipe hooked up to your shower, and expecting to get a shower from it by throwing a bucket of water at the other end.

@IdoCareForPeople It may dissipate in heat waveform, sice the magnetic field it generates can ionize molecules near it and make them move. I think we still have to do that, but we may already have a detector of full battery or just a voice recognoicer to turn it off if we say it....maybe...just suggesting...
