Nuclear Batteries Solve The Shrinking Gadget Conundrum [Batteries]

It sucks that batteries are nearly bigger than the gadgets they’re powering, but thanks to University of Missouri researchers and some tiny nuclear batteries, that’ll one day be an issue of the past. Yeah, you read right. Tiny. Nuclear. Batteries.

The real secret behind the size of the batteries is the use of new liquid semiconductors instead of tired old solid semiconductors. That’s great, because nuclear batteries aren’t a new idea, nor are they terrifying and harmful according to Jae Kwon, assistant professor of electrical and computer engineering at the University of Missouri:

“People hear the word ‘nuclear’ and think of something very dangerous,” he said. “However, nuclear power sources have already been safely powering a variety of devices, such as pace-makers, space satellites and underwater systems.”

Anyway, researchers are building and testing these batteries as you read this, but the bad news is that the initial focus is on powering micro/nanoelectromechanical systems, not remote controls. We can’t even begin to speculate as to when we would see tiny nuclear batteries in our local 7-Elevens. [University of Missouri via Boing Boing]

Gigantic iPhone charger packs 3000mAh battery

Whoever manipulated the above image to make this humongous iPhone battery pack look relatively manageable ought to be given a raise. Conversely, whoever wrote “It is not bulky either as it just extends a little at the bottom” in the product description ought to immediately undergo a workplace evaluation. If it happens to be the same person who handled both the photo and the product description, then God help us all.

Here’s what the $60 “Super Charger for iPhone” looks like from the side.

It’s big, I tell you. Big.

That’s okay, though, let’s just call a spade a spade and move on. There are, believe it or not, people out there who would be willing to put up with this brick in order to squeeze almost 2.5 full recharge cycles out of it.

Crank This Battery To Charge Up [Batteries]

The Wind Up Battery is a rechargeable battery with a little pop-out hand-crank to power up using some good ol’ fashioned elbow grease. I’d probably looks like an idiot using it, but better than suffering without a AA.

Designed by Qian Jiang, the concept is actually rather brilliant since it wouldn’t require an additional gadget to recharge your batteries and depending on how many recharges it would allow for, it might be a rather good deal too. Since this battery is still a concept, we’re a bit skeptical about the claim that it could be fully charged in 20 minutes, but that would be fast enough for most of us. Those of us who haven’t got the arm muscles of a noodle that is. [Yanko Design]

Battery 500 Project Wants to Make a 500 Mile Range Electric Car Battery [Science]

IBM, UC Berkeley and five US National Labs are collaborating in a consortium to make an electric vehicle battery that goes all the way up to 500 miles per charge.

The project wants to make this happen by using a lithium-air battery, which…

couple to atmospheric oxygen-essentially harnessing the oxygen in the air as the cathode of the battery. Since oxygen enters the battery on-demand, it offers an essentially unlimited amount of reactant, metered only by the surface area of its electrodes. IBM believes its nanoscale semiconductor fabrication techniques can increase the surface area of the lithium-air battery’s electrodes by at least 100 times, enabling them to meet the goals of the project.

If you think the consortium will deliver a fantastic car by the time you need to trade in your current vehicle, you should hold off on getting so excited. IBM says it’s going to be another two years to even see if the lithium-air batteries can be used to make the goal happen. [Smarter Technology via Slashdot]
