Aevex Gloves Self-Heat Using Hidden Lithium Batteries

Surprise, the reason your ski jacket doesn't have a heater in it is because nobody likes lugging around the car battery required to keep it running. But like many portable electronics, Aevex harnessed the stored energy of lithium-polymer batteries, form shaping them to fit snugly inside a glove. You get 4-6 hours of hand baking, allocated only where it's needed along your palm and fingers. The gloves themselves—the $300 Mountain Hardwear Red Savina and the $260 Outdoor Research PrimoVolta—get charged by being plugged into the wall, and are activated by pressing large obvious buttons on the exterior near the wrist. Inside, the fabric itself is a layering of power, comfort and thermostatic-control panels:


One layer reads the temperature of every part of your hand like a tightly knit grid, and allocates heat where it's coldest. When the finger gets warm, the heater eases off. Aevex says it'll have the jacket dilemma solved by 2009, and ditto for boots (or at least socks of some kind. Now, if we can all just try and forget about that whole "exploding lithium-ion battery" thing, I think we've got something. [Aevex via CNet]
