    Quote:
    A key point is that WiTricity does not use electromagnetic radiation, which would be inefficient and possibly hazardous. Instead, it relies on magnetically coupled resonance which gives efficient energy transfer and interacts very weakly with most common materials including living creatures. "The fact that magnetic fields interact so weakly with biological organisms is also important for safety considerations," said researcher Andre Kurs.

    It's cool yeah, I wouldn't exactly call it safe though.

    Said researcher Andre Kurs, who is also responsible for developing and marketing WiTricity....hmmmmmm

    cool stuff! wonder how much more crammed up we need the airwaves. we have mircrowaves, tv transmissions, radio transmissions, cell phone calls, ect ect. Now all we need is some electrical curent in the air in the "Mhrz" range :p

    but it would be nice for cell phones, flash lights, notebooks things like that.

    Tesla did this 100 years ago. MIT stole his ideas and gave no credit to him. Shame.

    ...does not use electromagnetic radiation? Are they serious? An oscillating magnetic field IS electro magnetic radiation. Do these people never go to college? It's called induction, no matter what MIT boy says. An oscillating magnetic field inducing a current = induction.

    that isn't electromagnetic radiation, that is electromagnetic induction. light is consistent of electric and magnetic fields feeding eachother. A magnetic field nor an electric field by itself is radiation. If you can't "see" it (visible light, Infrared cam, X-Ray cam, etc.), then it isn't radiation. I know we at GaTech should be bashing MIT as well, but you can't say they don't know their fizzix.
