Submission + - MIT team demonstrates wireless power transfer (mit.edu)
tuomas_kaikkonen writes: "MIT team demonstrated the wireless electricity based on using coupled resonant objects. Two resonant objects of the same resonant frequency tend to exchange energy efficiently, while interacting weakly with extraneous off-resonant objects. They were able to light a 60W light bulb from a power source seven feet (more than two meters) away; there was no physical connection between the source and the appliance. The work has been reported in the June 7 issue of Science Express, the advance online publication of the journal Science."
