This military brainchild may be the solution for limitless power. To be used to reduce the need to carry extra lithium pack for the soldiers, this bag can be used to charge packs or any device connected to it. At a walking speed 8 watts of power is generated, but at running speed it can generate 44 watts. The bag is suspended on a kinetic rail system that can use the up and down movement of walking and convert it into power. The tracks can be locked if a stationary mode is desired as well. It is capable of regulating its power output and had a shoulder mounted power meter. This could revolutionize power generation for the future.
