The Lesotho Cooker is named for the small African country where it is made. It is a solar box cooker design that is larger than a typical family-size cookers, and prepare meals for 10-15 people. It is constructed mostly of metal, made to handle frequent use, and designed to last quite a long time. Wood to used for construction is in limited supply in the area, and metal construction is one answer to this problem. Given the conductive nature on metal, an oven like this needs to be wee insulated.
Inside the oven, the food is arranged on stepped shelving to maximize exposure to the sun. The top reflector also can fold down over the oven when not in use.
