Paper Batteries Recharge Using Moisture in the Air

Straight from the "holy crap there's no way that should work" file, we have this amazing story about paper batteries that use moisture in the air to charge. Thanks to Martin for the linkage.

What's exciting here is that these batts charge with water, and they don't need very much of the stuff to juice up. Just 40 percent humidity in the air is enough to regain their potency, a threshold that might put them out of the realm of possibility for self-recharging power for Vegas lights, but something tells us the voltage coming out of this pulp couldn't cope with that kind of strain anyhow.
