The Goat

Hang the Mini Wiz out the window of your Jeep to charge up the car battery after the alternator dies. It won’t give you enough energy to get out of the backcountry, but it will supply some juice to your iPod for the walk back to the highway. Thirty minutes of heavy wind will produce enough energy in the Mini Wiz’s internal battery to fully charge your iPod, and you can plug the Wiz into a wall outlet so you set out with a full charge. Might not be a bad idea for the guy who always forgets to buy new batteries for his GPS, but I don’t think I’d rely on it for an avalanche beacon.
