You think WiFi was revolutionary, picture technological advances that WiTricity will bring. WiTricity? Yes, transmitting electricity wirelessly. In an experiment revealed last week, a team from the Massachusetts Institute of Technology's departments of Physics, Electrical Engineering and Computer Science, and the Institute for Soldier Nanotechnologies lit a 60-watt light bulb from a power source seven feet away with no physical connection between the power source and the bulb. The researchers employed two magnetic coils, 20 inches in diameter, designed to resonate together. The team labeled the concept WiTricity, for wireless electricity.




"Imagine a future in which wireless power transfer is feasible: cell phones, household robots, mp3 players, laptop computers and other portable electronics capable of charging themselves without ever being plugged in, freeing us from that final, ubiquitous power wire," an MIT statement says. "Some of these devices might not even need their bulky batteries to operate."
According to the researchers, power levels more than sufficient to run a laptop can be efficiently transferred over room-sized distances even when objects completely obstruct the line-of-sight between the power source and appliance. "As long as the laptop is in a room equipped with a source of such wireless power, it would charge automatically, without having to be plugged in," one of the researchers, MIT physics professor Peter Fisher, said in a statement. "In fact, it would not even need a battery to operate inside of such a room."

If [or should it be when] commercialized, the researchers foresee, WiTricity could cut society's dependence on those heavy and expensive batteries.

I think it's a pretty good idea. It would help eliminate some of those telephone poles folk keep running into.



But seriously, what kinda effects would 'waves' cause to our bodies? Don't they say cell phones cause cancer or somesuch?

Cell phones don't cause cancer, it's a myth. The energy eminating from a cell phone doesn't have the power nor the frequency to damage human tissue. It's fear mongering.

dammit.

If witricity is an eventually to be realized reality electric cars will not be far behind as electric generating stations are built across the countryside. Just think, no more noisy, pollution automobiles.

Yes they cause cancer...whats more it that they eat holes in your brain. Cell phones are high powered tranceivers that communicate to towers a mile+ away. And you hold them right next to your brain.

Phone Study: Holey Rat's Brains

In a study that may shed some light on whether cell-phone use is harmful to callers, Swedish scientists found that radiation emitted by the world's most common mobile phones burns holes in the brains of rats.

Swedish neurosurgeon Leif Salford and his team tested the radiation emitted from Global System for Mobile communications phones on 12- to 26-week-old rats. The age group of the animals tested, researchers say, is equivalent to that of human teenagers -- who tend to lead the pack in cell-phone use worldwide. GSM phones are the most commonly used around the globe, particularly in Europe, Asia and the Middle East.

You have more power flowing through your body from 20+ radio stations 24/7 than you'll ever get from a 1/3 watt transmitter in your cell phone.

Not to mention such sources as the radar at the local airport, weather radars, and television broadcast stations.
