Physicists Promise Wireless Power

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.'"

    It would also suck to have a random bdy part resonate in a similar frequency ...

          I dunno, I guess it all depends on exactly WHICH body part we're talking about... this might revolutionize the online pr0n industry :)

    As others have mentioned the author and title of the story you're looking for, I'd just like to chip in that, in a similar vein, "Blood Music" by Greg Bear is also quite good. It's about a guy who invents intelligent white blood cells and injects himself with them.
