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.

Nissan Leaf launches in Europe, takes us for a drive
26,000 people can't be wrong, right? That's the current tally of Leaf pre-orders that Nissan has collected from US and Japanese drivers excited by its all-electric hatchback. Yesterday, the car that's built to plug into the same wall outlet as your toaster held its official pan-European launch party -- with the UK, Ireland, Netherlands, and Portugal getting the first deliveries in early 2011 -- and we were on site to grab a few closeup pictures and some precious time in the driver's seat. American drivers should look out for a new set of keys in their mailbox this December, so there's probably no better time than now to give them a preview of what they're getting themselves into.
