Wireless Energy Transfer

Just read an article on The Christian Science Monitor that a new technology is being developed where energy is being transferred between two electronic devices via airwaves.

So, let's say you're walking down the street and your cell phone starts to die on you because your battery is low. Soon, you might be able to walk to your nearest recharging station and just stand there as your cell phone recharges.

Quoting from the article:
"His idea involves "electromagnetic resonances," in which energy jumps between two locations, as it does for very short distances inside an electric motor or transformer. "It's a very general phenomenon in nature," Soljacic says. "In quantum mechanics, it's called 'tunneling.' In electromagnetics, it's called 'evanescent coupling."
