Physicists Promise Wireless Power

Posted by ryuzaki0 on from the having-a-hard-time-buying-it dept.

StrongGlad writes "The tangle of cables and plugs needed to recharge today's electronic gadgets could soon be a thing of the past. Researchers at MIT have outlined a relatively simple system that could deliver power wirelessly to devices such as laptop computers or MP3 players. In a nutshell, their solution entails installing special 'non-radiative' antennae with identical resonant frequencies on both the power transmitter and the receiving device. Any energy not diverted into a gadget or appliance is simply reabsorbed. The system currently under development is designed to operate at distances of 3 to 5 meters, but the researchers claim that it could be adapted to factory-scale applications, or miniaturized for use in the 'microscopic world.'"

    I bet I'm not the only one here who has taken the piss out of someone for asking if they can get a wireless power supply for their laptop

    Fortunately there are no health issues with Lithium-ion batteries. I sleep with my laptop.

    Thats why I try not to move around too much, go out in the sun, or wear pants.

    Any one of those could heat up my cells a little bit and give me cancer!
