Dirt powered battery for rural Africa

Scientists have known for some time that an electrical charge could be harvested from the metabolic processes of bacteria living in soil but the effort required to achieve this was time consuming for a very low power output. But a team of Harvard scientists has used the idea to design an inexpensive battery, a microbial fuel cell, which can produce enough current to power LED lights and charge cellphone batteries in rural Africa.
