Ah, wireless power. One of those mythical mysteries that are far more likely to remain "something to strive for" rather than "the next big thing." Oh sure, we've got Palm's Touchstone and the Powermat, but until we can hang a 50-inch plasma from our bedroom ceiling and power it up without a single wire, we'll remain firmly unsatisfied. Thankfully for those of us in that camp, MIT exists, and a few of the school's best and brightest are toiling around the clock in order to develop a technology that would power not one, but multiple devices sans cabling. Thanks to the wonders of coupling resonance, we're told that the "overall power transfer efficiency of the wireless system could be increased by powering multiple devices simultaneously, rather than each device individually." In theory, the system could be implemented by "embedding a large copper coil in the wall or ceiling of a room," but there's obviously no set time frame for release. We'll be looking for you geeks at CES next year, okay?
