We improve life in rural communities with affordable technologies to ease the burden of work. We have a bicycle-powered maize sheller that can shell maize up to three times faster than traditional methods in order to reduce post-harvest grain losses as well as an ultra low-cost handheld maize sheller that can reduce the burden for people shelling small quantities of maize. We also have a bicycle-powered phone charger and a motorcycle powered phone charger so that people who do not have reliable electricity can charge their phone whenever they need.
