Bacteria Powered Cellphone Charger

A bacteria-powered cellphone charger could keep people in developing countries talking, even when they live far from the grid.

Cellphones are increasingly vital to everyday life, and the economy of many developing countries. But in some areas electricity to charge them can be hard to come by.

To tackle the problem, a team of students from MIT has designed a microbial fuel cell (MFC) that runs on plant waste.

Their prototype won the $5,000 first prize in a contest called MADMEC
