These bakeries serve multiple functions, depending on the needs of the particular community in which they are used. Numerous villages in 40 countries are now home to trained villagers who manage bakeries that produce food for their communities and produce a small profit from sales to outsiders. A tiny bakery in the Dominican Republic, operated by a parish priest, is the sole source of baked goods for people living in nearby communities in Haiti. Elsewhere in the Dominican Republic, a school for the blind uses two large ovens to teach their students operating skills, self-sufficiency and business methods. In Angola, a school of 4000 uses a solar oven to produce 1000 meals per day for students.
