Wireless Electricity! :O

Yeah you heard

We're One Step Closer to Wireless Electricity!



Ugh, what I wouldn't do to rid my house of the snake-like electrical cords coming out of my computer monitor, external drive, laptop, stereo, TV, etc. I'm tired of getting my office chair tangled up with the mess under my desk! Well, my wish for wireless electricity may not be too far off. Researchers at M.I.T. have successfully transmitted enough power across a room to light a 60-watt bulb. They've christened their technique, WiTricity.

The MIT design consists of two copper coils. One, attached to the power source, is the sending unit. Rather than send out electromagnetic waves, it fills the space around it with a magnetic field oscillating at a particular frequency. The second copper coil is designed to resonate with that oscillating magnetic field. A copper coil within an oscillating magnetic field generates a current, enough, in MIT's case, to power a light bulb. Power transformers make use of something similar, called magnetic induction, to transmit power between coils over short distances. But those coils aren't designed to resonate with each other. Resonant coupling makes the transfer of energy almost a million times more efficient.
Since the magnetic field doesn't radiate, most of the power that isn't picked up by the receiving unit is bound to the originating coil, rather than being lost into the environment. That also means that this system has a limited range, and the smaller the receiver, the smaller that range is.

EUREEKA!

I wonder what it will be like living in a magnetic field tough!

i swear this has been posted before... think i was told about this 6 months ago... intrestin g tho

O.o rly??

[Emzii.]

Our brains would probaly frazzle.

i heard about that ages ago, but you would think if would fry everything in sight. Wierddddd

[Colin-Roberts]

theres already wireless electrical lamps, theres other wireless electric adapters too. i'll maybe post some later.

Ohh kwl ide like to see that plz

[OMGitsaROSS]

that dangerous, surely if your holding a fork or knife or something metal you can get electoructred?

You'd get cancer too..

So maybe it's not one of the better inventions
