New Technology Allows Wireless Recharging

A “non-radiative” electromagnetic field is a state of electric and magnetic fields which are localized someplace on the device and in the source, said John Joannopoulos, a researcher from MIT. “Localized means that electromagnetic fields will die off as you go away from the device or the source.”The energy could then be picked up by especially designed gadgets. What's not picked up by the receiver is then reabsorbed by the emitter.It’s not dangerous at all, Joannopoulos told LiveScience.The technology will initially have a short range at first, the researchers expect. A laptop could be recharged within a few yards of the power source.
