With more and more gear and gadgetry being added to soldiers' arsenals all the time, getting all their equipment juiced up and ready to go is becoming more and more of an issue. The Australian Army has decided to give going green a try, adding solar panels to the backpacks worn by their soldiers.
Weighing a mere 14 ounces, they don't bog the packs down all too much, and they an provide low-level energy to devices such as radios, night-vision goggles, comm. equipment, and sensors. They'll still need to use traditional batteries as well, but the panels should help provide a bit of extra juice as well as free recharges while out in the sun.
