Power Your Phone With Dirt

A team from the Harvard School of Engineering and Applied Sciences (SEAS) is working on a microbial fuel cell-based charger - a mobile phone charging system that gets its power from microbes in the soil.

The project is being led by Dr. Aviva Presser Aiden, an affiliate of SEAS and a current student at Harvard Medical School. Her device incorporates a conductive surface, that harvests free electrons created by naturally-occurring soil microbes during the course of their metabolic processes. She has already used the technology to power LED lights in a lab for 14 months.
