Off-grid communities such as those in sub-Saharan Africa can pay thousands of times as much as the rest of us for their energy. Designer Jim Reeves has developed a simple, low-cost gear-train and generator that uses a descending weight to power a perpetual light source. Children can do their homework and study, families and friends can eat together and interact after dark adding new dimensions and possibilities to their lives.  This is one of a three-part series for the Guardian highlighting some of the world's most innovative sustainable energy plans.
