A tiny generator sparks to life with every step.
The U.S. Army has some wacky ideas to keep soldiers' futuristic gear working, even when they're far away from the nearest outlet.
To keep their gear juiced up, researchers at the Army's C5ISR Center patented a bizarre new portable generator that can fit inside a soldier's boot, Army Times reports. Every time a soldier takes a step, their foot triggers a small mechanism that creates a small electrical charge — not big enough to solve the energy crisis, but perhaps enough to keep personal electronics running.
The weird power-boots are just the first step in the military's plan to turn soldiers into walking battery packs, per Army Times. Army researchers are also trying to build kinetic energy harvesters into high-tech knee braces and backpacks as well.
But some of these devices are actually making soldiers' lives worse. For instance, the backpack only harvested energy when it was loose-fitting and able to bounce around — making it cumbersome to carry.
