WiTricity wireless power
At the TED Global Conference in Oxford, UK wrapping up today, US-based WiTricity showed off a wireless charging system that powered up a T-Mobile G1, Apple's iPhone and a flat screen TV. Such a system could eventually replace the current infrastructure that involves countless miles of power cable and disposable alkaline batteries. According to a recent BBC report, the system is based on research by a physicist at the Massachusetts Institute of Technology (MIT), Marin Soljacic. It uses low frequency electromagnetic wave resonance to transfer the energy from the source to the device via a coil at each end.
