Wireless electricty

[Goat Roper]

Coolest tech thing I have seen in sometime. Worth it to watch all the way through


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.(Recorded at TEDGlobal 2009, July 2009 in Oxford, UK. Duration: 10:10)

*Watching the video now*

[Holeshot]

Defiantly worth watching. Really cool !!

Totally sweet. Now just let somebody else try it for 10 years and if they don't get tumors or melt their fillings, I'm in!

[Reverend Cooper]

really cool,untill you grow lumps on your body from it

[Bobby "Big Daddy" Flay]

Kinda slick

[Goat Roper]

I was kind of thinking the same thing

[PonyKiller87]

Cool shit, I read something in a magazine about that a while ago, looks like its finaly happening.

We already live in a magnetic field...Earth!

I am a little shocked at the supposed 50% efficiency rating! Just as they mentioned early in the video the basis of the technology was based on Telsa's work about 100 years ago... Except using a Telsa coil to transmit electricity is WAY less efficient. It would be really interesting to understand how they tune to the RF to get such high efficiencies and also see how the efficiency drops depending on distance to the transmitter.

Very cool stuff tho... Just as he mentioned the electric car in the garage would be pretty damn nice! (Although at this point I would still rather pay 1/2 as much and just plug it in :) )

I was going to say, Tesla did this a long time ago, haha. I'll have to check out the movie later.

I can't see how small magnetic fields are going to cause "tumors and lumps"?

Same way looking into a microwave will or any of that other crap your parents told you would happen when you were a kid. :rolleyes:

[Moparjim]

this is nothing new, been around as others have said basically since Tesla. the efficiency is the killer that has kept it from any practical use. still is.

[PonyKiller87]

I see the big issue being you have this coil energized all the time just waiting for somethign to come into its range to be powered. All transformers have some current draw at idle even if it isn't powering anything. Everything from a small phone charger up to the transformer on the pole outside your house.

So if they can make this thing so it turns off the coil until it detects a device that is looking for power in the range then turns it on it might work, otherwise it will waste a ton of power on our already weak elec grid.

I was joking. Kinda like a cell phone is going to take down a 747, but now they have WiFi services. It's one of those things that makes society all scared and after time it becomes a standard. Like Microwaves and margarine, cell phones, and electric shavers.

[SSmike1]

yes
i skipped to the REAL DEAL. :)
