Researchers collaborating in British Columbia, Pennsylvania, and Michigan have created a device which generates energy by assisting deceleration of the leg during a normal walking stride. The technique is similar to that used in some hybrid cars, which generate electricity through braking.
The current prototype device can produce enough power in one minute to run a cell phone for ten minutes straight.
Early uses for the device will likely include powering artificial limbs, but this line of discovery opens up enticing possibilities for the future. Will we see humans one day generating all the energy they need from the simple act of walking?
