Taking precautions and becoming more eco-friendly seem to go hand-in-hand with the US Army's latest development, the TEMPER Fly. This solar-powered tent will be used in various ways from charging batteries to ensuring that communications never go down.
The TEMPER Fly tent is made possible thanks to thin, flexible solar cells. Able to generate 800 watts of electricity, it could prove invaluable on the field. A smaller version called QUADrant is also available.
