A little gizmo with one heckuva claim was demonstrated at the Consumer Electronics Show (CES) recently. The Airnergy by RCA claims to be able to scavenge enough energy from WiFi (and presumably the 2.4GHz band) to juice up its own internal battery and allow a user to charge up devices on the go:

Perhaps this should be in the Product Claims subforum, but I can't imagine how long it'd take to build up even a few dozen mAh of charge with 40 mW routers. Perhaps as an emergency, always available source, but as something used on a regular basis? I don't know if I buy it.
