Dirt Powered Fuel Cells for Light
An organization called Lebônê is working to provide low-cost energy solutions for Africa. They've developed a simple, low maintenance system that derives energy from dirt- microbes breaking down organic matter. This energy can be used to charge a battery, hopefully replacing hazardous kerosene lamps that are currently in widespread use.
Although the model is currently on trial, it may soon be available for use across Tanzania.
