Tired of recharging the numerous electronic devices that have become an esssential part of your lifestyle, and the snarl of wires involved? You can take heart in a ferment of technical development occurring at MIT where they have demonstrated wireless power transfer, and Texas Instruments where self-charging electronics and energy-efficient microchips are in the news.
MIT refers to its concept as WiTricity (wireless electricity), making it possible for cell phones, household robots, mp3 players, laptop computers and other portable elecronics to charge themselves without ever being plugged in. It is accomplished by coupling resonant objects of the same frequency. The technology is rooted in well known laws of physics.
