We know, energy without wires has always seemed like one of those novel concepts that sounds terrific in theory, but remains a tad difficult to imagine hitting the commercial scene for some time to come. Apparently, all that is about to become nonsense, as a Pennsylvania-based startup is set to capture the wireless-loving hearts of, um, everyone when it tackles contactless power products. Powercast has already "signed nondisclosure agreements to develop products with more than 100 companies (Philips, for instance), including major manufacturers of cellphones, MP3 players, automotive parts, temperature sensors, hearing aids, and medical implants." The firm's radio-wave-receiving miracle device trumps existing attempts by "adjusting to variations in load and field strength while maintaining a constant DC voltage," essentially ensuring that only low wattages (read: the stuff that garners FCC admiration) are flung around. The system basically consists of two parts -- a wall-plug transmitter and a "dime-sized receiver" that handles the real magic -- and energy is instantly transmitted whenever that disc comes within a yard or so of its tag-team partner. Incredibly, the receiver only costs "about $5" to produce, yet the outfit has already secured upwards of $10 million in private funding, which translates into one less American that desperately needs to win the lottery. Get ready folks, if all goes well, Powercast will be shipping "many millions of units" by the end of 2008 -- and maybe even sooner.
