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.

    New battery technology

    There is a new LiON battery technology that can withstand more than 9,000 deep-discharge cycles, does not have the problem with thermal runaway, and can be recharged very quickly. The one drawback is a slightly smaller energy capacity, which I could easily live with in exchange for never having to replace another cellphone, PDA, or laptop battery.

    For devices which have intermittent use, such as laptops and cellphones, I don't see any need for wireless power. For things that run continuously, wireless power is not likely to be economical enough to replace the AC cord.
