A few other ideas should also be mentioned in this context.
Here in Israel, we have a startup called StoreDot (http
/store-dot.com) that has created an organic battery that uses compounds derived from cancer research (believe it or not) that allow you to fully charge your phone battery in 60 seconds. That company is already in discussions with several large phone producers to market their tech.
Then there's wi-charge (http
/www.wi-charge.com) that uses an infra-red beam to charge phones remotely - meaning no EM radiation or the associated potential heath risks.
These are just 2 examples.
