Sony demos paper-fueled battery; Paper Mario runs for life
Remember Sony's sugar high from a few years back? Sony has been trying to get electric results from glucose-based batteries for some time. But with the competition showing off cool concepts like Coke-powered phones, Sony's Bio Battery program brought its latest development to Eco-Products 2011 in Tokyo. This info just might be worth the paper it's printed on because, well, the battery runs on paper. By using the enzyme cellulase, the device can break down the glucose from cellulose-rich paper or cardboard, which generates enough energy to run a small fan. It's not quite ready for prime time, but given the potential of easily turning junk mail into electricity at a more portable scale, this is certainly worth a continued look.
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.

Stanford wants to roll its own paper batteries
It was only a couple of months ago that MIT was wooing us with the energy-preserving properties of carbon nanotubes, and in a classic act of oneupmanship Stanford has now come out and demonstrated paper batteries, which work thanks to a carbon nanotube and silver nanowire "ink." We've seen this idea before, but the ability to just douse a sheet of paper in the proper magical goo and make a battery out of it is as new as it is mindblowing. Battery weight can, as a result, be reduced by 20 percent, and the fast energy discharge of this technology lends itself to utilization in electric vehicles. The video after the break should enlighten and thrill you in equal measures.
Researchers develop bendable, paper-based battery
Nah, the researchers at Rensselaer Polytechnic Institute won't be crowned the first to develop a flexible (or paper-based, for that matter) battery, but their minuscule prototype "is an integrated device, not a combination of pieces" as others typically are. The battery uses "paper infused with an electrolyte and carbon nanotubes that are embedded in the paper," and could eventually be utilized in combination with solar cells or "scaled up and shaped into something like a car door, offering moving electrical storage and power when needed." Currently, however, the wee samples can release just "2.3-volts, or enough to illuminate a small light," but the idea of using these things to power pacemakers and the like isn't that far fetched.[Via BBC, thanks to everyone who sent this in]
Rocket develops "paper battery" for use with RFID, cosmetics
Nearly a year after NEC rolled out its paper-thin ORB batteries, Korean battery manufacturer Rocket is launching (ahem) its own uber-thin battery. While juicy, scientific details aren't readily available, we do know that the "paper battery" won't include any toxic chemicals, is "flexible and thin," and molds together the companies "thin film technologies" with its battery knowledge. The company hopes to entice heavy RFID users, smart card manufacturers, and "cosmetic / drug delivery system" providers to utilize the paper battery in powering the already-miniscule devices. Oddly, Rocket also envisions its new creation being used in "teeth whitening, anti-aging, and wrinkle care," though we're not exactly sure how electrifying a tooth will brighten your smile. Nevertheless, the company hopes to have its newfangled power source attached to crates and body parts real soon, and confidently assures us that it "doesn't cause explosions or fires." Phew.
