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.

    Lightening

    Yes, lightening, and its lower powered alter-ego static electricity, do travel through the air but they are point to point transfers of current from an area of higher potential to one of lower. In the low power version the discharge causes a slight tingle. In the more dramatic version, there are severe deleterious effects on the recipient. I'm not sure that thousands of point to point discharges to power vehicles or whatever are practical. And, the thought of some sort of pervasive EM field, one strong enough to power some sort of general use device, is not all that attractive. But, how cool would it be if someone gets it right and we can just draw power for our electirc cars directly from the "air"?!
