Scientists Develop New Dirt-Powered Fuel Cell That Runs Forever
Northwestern University researchers have introduced a soil-microbe-powered fuel cell, significantly outperforming similar technologies and providing a sustainable solution for powering low-energy devices.
The goal is to power sensors in agricultural contexts, and if that works, great. You could do some amazing things if you know exactly what’s in your soil (humidity, nutrients, etc) without having to first lay cables to create a powered network or whatever. It could save water and stop farmers from using excessive fertiliser.
