Harvard scientists believe in the power of the good earth — literally. A team at the Boston-based college have created microbial fuel cell (MFC) batteries that derive energy from naturally occurring bacteria in soil. If the product takes off, the eco-friendly batteries could provide power for some of the 500 million people in sub-Saharan Africa who lack access to electricity.

Take a little bit of soil, add some microbes, a little bit of human ingenuity and you’ll find yourself with the most unlikely source of power ever – dirt! Building off of this simple concept, a team from Harvard led by Hugo Van Vuuren have just been named amongst the winners of the World Bank’s Lighting Africa 2008 Development Competition. Their idea is to develop a series of dirt based fuel cells that are capable of lighting high efficiency LED lamps and their goal is to light up Africa.
