"The new phone books are here, the new phone books are here.  I'm somebody!"  The famous line from "The Jerk" summarizes my single citation in Wikipedia.  (And I really didn't put it in myself.  Don't know who did - which is weird but cool.)

A while back I coined the term witricity for an idea I had about trickle charging batteries (especially cell phones) using ambient RF energy.  The basic idea was to use a rectifying antenna to convert RF into extrememly low voltage, then create a "ladder of capicators" to capture the energy until there was enough juice to shoot a little into a battery.  Wait.  Repeat.  And you wind up with batteries that charge themselves when left alone.

Anyhow, WiTricity® (I sold the term and domain name to the company a couple of years ago) works very differently.  It uses highly efficient magnetic resonance to provide things like laptops with useful realtime current when near a WiTricity® transponder. 

CNN just did a nice piece of the technology.

Very cool.  Check out their site.  I have to go pick out a thermos for someone.
