got sun?

This is cool. If, like me, you tire of purchasing new AA batteries for your camera/gps/mp3 player/flashlight/etc., or will be traveling in a foreign country with wonky electrical outlets and cannot use your rechargeables, try going solar. Sundance Solar sells a variety of lightweight rechargers for AA, AAA, 9 volt and other batteries, most of which fit into your pocket. My favorite is the Foldable Solar Battery Charger, which was originally designed for the military and weighs only 7.2 oz. with 4 AA's in it. According to the specs, 2 batteries charge in about 4 hours of full sun, 4 batteries charge in about 8 hours. The charger "adds less weight than carrying 4 extra batteries." Not bad, unless you'll be vacationing in the Arctic during the dark season.
