"Endless Energy: Dirt-Powered Fuel Cell Breakthrough"
Northwestern University researchers have developed a soil-microbe-powered fuel cell that outperforms similar technologies, providing a sustainable solution for powering low-energy devices. The fuel cell, about the size of a paperback book, can fuel underground sensors used in precision agriculture and green infrastructure, offering a renewable alternative to batteries. The technology harnesses energy from microbes living in soil and has been shown to work in both wet and dry conditions, outlasting similar technologies by 120%. The researchers have made all designs and tools public for widespread application.
