Paper batteries recharge from moisture in the air, seemingly defy laws of nature

Some like working with clay, some like carving from stone, others etch out of silicon, but the team at CENIMAT apparently really likes plain 'ol paper. The researchers there proved they could print transistors on the stuff back in 2008, and now they're making paper batteries too. But that's nothing new, others have made mache cells for years. 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.
