Cell Phone Runs on Single AA Battery
Willcom and Sanyo got together to develop this thing, a cell phone that runs off of a single AA battery. Which, with no screen or anything, doesn't seem like that much of a feat. I mean it only gets 5 hours of talk time and 250 hours of standby. Now if it ran off brainpower, then we'd have something. Who needs caller ID or to store naked pictures of ex-girlfriends on your phone when you can have this thing. Which, I might add, looks remarkably like the "lightsaber" I found in my girlfriend's underwear drawer.
