Researchers Not Giving Up On Dream Of Wireless Power

from the but-I'm-not-the-only-one dept

At some point or another, everybody's fantasized about it: wouldn't it be great if an electronic device could be powered wirelessly, fully eliminating the need for cables? It's an idea that's been talked about for a long time, back to the work of Nikola Tesla. Now a new team of researchers at MIT is going after the problem again. They believe that there's solid physics backing the idea up, and in fact their research builds on Tesla's original work. Still, this is firmly at the theoretical stages. Consider how long it's taking for fuel cell powered mobile devices to take off. We can safely say that this will take a much, much longer, if it ever comes about.

    sure, you can have wireless power. Motors/generators are wireless power. look at how big they are.

    look at transformers. they transfer power wirelessly. albiet over small distances.

    sure, it's possible, however the ammount of energy needed to transmit the power would probably greatly overshaddow the usefullness of wireless power.

    unless there is some type of "quantum" device that can broadcast shortrange low power, and have another device that can "use it" kinda like RF ID tags. right?

    i doubt we'll get to the point where our ipods/cellpones/laptops will recharge/run off of this wireless power.

    plus, won't it cause cancer?
