Socks Generate Electricity Using Microbes Fed by Urine
A pair of sock-like generators, designed by robotics professor Ioannis Ieropoulos’s team at the University of the West of England in Bristol, U.K., are able to turn human waste and locomotion into electrical power with a bit of help from microbes.
The crux of the idea was to create a self-contained system for generating power, with an eye toward survivalist scenarios.
