An Electric Metad
Deforestation is already causing problems for the wood supply in the Horn of Africa where family incomes and living standards are very low. A metad, or magogo is a special type of cooker used in Ethiopia to bake injera, the large round form of flat bread which is the usual basis for an Ethiopian meal. In its traditional clay form injera is heated on a fire or stove, burning eucalyptus wood gathered from the surrounding countryside. This particular design of stove could also be used for baking other forms of flat bread. The prototype for Field-testing was produced using the total design method. The metad is normally 420 to 600mrn in diameter, and 20mm thick. The hot plate is made of a thermal-conducting material such as cast-iron or aluminium, although the use of traditional ceramic materials is still being considered because of their much lower cost. The other components may be made of metal or plastic. After further development the new electrically heated model now has a 3kW, 240 volt element similar to that used in a conventional boiling ring. The objective is to develop a design which can be powered from the high solar radiation experienced during the long dry seasons in Ethiopia, Eritrea, and the Sudan. The use of a natural gas heater will also be investigated. This is a summary of a report which was prepared as part of an MSc in Product Design at South Bank University, London.
