Peanuts are an important crop in many developing countries. But getting them out of their shells is tiring without a machine. (29) In 2001, a Canadian inventor, Jock Brandis, designed a hand-powered peanut shelter for a village in Mali. It can shell about 56 kilograms of peanuts in one hour. By the end of this year, 20 countries will be using the Universal Nut Shelter and other technologies from the Full Belly Project. This nonprofit group was established in North Carolina in 2003. (30) The aim is to fight hunger and help rural economies with labor-saving agricultural devices that can be reproduced locally. Former Peace Corps volunteer Jeff Rose heads the Full Belly Project. He says a village in Malawi used a single shelter to process 30 tons of peanuts over two months. Selling them raised $16 000. The United States Agency for International Development also provided money, and the village was able to build a water well. That single machine, says Jeff Rose, costs the village just $28 to make. There are two main ways that the group provides its technologies. One is where individuals or groups based in the United States donate $ 700. In return, they take a kit and build the shelter in a developing country. The second way the group distributes its machines is through partnerships with nongovernmental organizations. The Full Belly Project also has a pedal-powered shelter. Now, volunteers are designing a pedal-powered grain crusher. (31)Goals for the future include all the simple technologies needed to make ready-to-use healthy foods to treat malnutrition.
