November 2007: The Organisation for Rural Education Simplicity (ORES) has been carrying out solar cooker research for several months. After experimenting with parabolic cookers, which they found difficult to keep focused on the sun as it moves, they chose to develop a solar box cooker that can cook for five people. The box can be closed to keep water warm overnight. Glass and mirrors are the only cooker materials that are not produced locally. Production cost is about $150 per cooker. Although ORES is based in Bamenda, in the western part of Cameroon, ORES hopes to promote the cookers in northern Cameroon where the Sahara Desert is encroaching and where the sun shines nine months per year.
Northern part of the country: Sunny throughout the year and local sources of firewood are depleted. The north is a good region for solar cooking. Southern part of the country: Abundant rain and abundant firewood. (Source: Juan Urrutia Sanz, 2010-Feb-15)
