Description These are usually concave disks that focus the light onto the bottom of a pot. The advantage is that foods cook about as fast as on a conventional stove. The disadvantage is that they are complicated to make, they must be focused often to follow the sun, and they can cause burns and eye injury if not used correctly. Some of these concerns have recently been reduced.
Major Components
The major components of the cooker will be as below :
Reflecting Bow It is a parabolic dish made of reflecting sheets supported on suitable rings for holding them in a fixed position. The sheets are joined together in such a way that they automatically form the parabolic shape. The structure and frame of the bowl are made strong so that the reflectors do not get deformed while turning it in various directions.
