Energy-Generating Shoes Power iPods


For shame. We know good and well engineers can concoct energy-generating garb that actually looks good enough to wear, but evidently those fashion-minded gurus weren't hired for this project. Granted, we have all ideas the image you're quizzically staring at above is NTT's first go at a pair of power-packing sandals, but there's clearly a good ways to go before these things are cute / safe enough to wear on the streets. Might we suggest shoving all that hardware inside of something? The "all hanging out" look just isn't working here.

Toshiba's New Battery Gets 90% Charge in 10 Minutes


Imagine this -- you, sitting in a dingy airport terminal waiting on your flight with a lifeless laptop and just 10 minutes to spare. You've got oodles of spreadsheet work to do before 8:00AM tomorrow, and unless you get it done on this flight, you're fubared. Toshiba is looking to make said scenario seem like one that's not so grim, as its prototype SCIB (Super Charge Ion Battery) purportedly has the potential to get 90-percent full in just 10 minutes. The battery was unveiled at CEATEC 2008 in Japan, though little was known about its eventual availability. Shame development cycles can't be fast tracked in a similar manner, huh? [Via UberReview]

Charge Your Gadgets with Excess Heat

Charge your Gadgets with Excess Heat

You know that somewhat discomforting warmth that comes from your cell phone when you use it? A lot of people joke that it's the radiation slowly cooking your brain, but really it's just a combination of the heat from the battery, the processors inside your phone, and of course your face. Any time any mechanical or electrical device gets warm (excepting toasters and hair driers and the like) it's a sign of wasted electricity, and two teams of researchers are working on ways to capture that heat and turn it back into power.

The researchers are focusing on the use of nanowires to capture this heat and generate electricity from it. Nanowires are just what they sound like: wires that are very, very small. You'd have to lay somewhere between 5,000 and 8,000 of these nanowires side-by-side to equal the width of a human hair. Bundles of the wires are placed between heat sources and, with some chemical and electrical tweaking, are capable of conducting electricity when a temperature difference is applied to them.

Cell phones are the first mentioned application, but think about a car that uses exhaust heat instead of an alternator, or a laptop that charges its battery instead of warming up your lap. The potential is exciting, but is in the very early stages of experimentation, so you won't be finding nanowire regenerative charging in your next gadget for a few years at the very least.
