In 2017, Army scientists will be testing an energy-harvesting device that straps to the legs and generates power from walking. The PowerWalk is designed to extract the energy expended when the knee is flexed and negative work is being performed. The system adjusts to a person’s gait, so soldiers don’t feel like they are wearing a device and can even forget that they have it on, according to a recent Army press release.

US soldiers carry about 100 pounds of gear for a 72 hour mission and 16-20 pounds is for batteries.
