You think your backpack is loaded down with gadgets and stuff to get through the day? Your burden is nothing compared to a soldier who carries approximately 100-150 pounds of tactical gear and gadgets (not to mention the batteries to power it all). As a way of lightening their load, researchers at the Australian National University have developed super thin and lightweight solar panels so that they can charge on the go. These wearable solar panels, called ‘Sliver’, can generate up to 140 W of power and are being made right here in the US.
