A type of solar collector that concentrates solar radiation with the help of a reflecting surface on the back, top, and bottom sides of a container. There are three main types: the box-style cooker, the panel cooker, and the parabolic cooker. Each type has pros and cons when compared on its heating ability, ease of construction, and ease and safety of use.
Many different patterns and plans are available that can be adapted to work with whatever materials are to hand. While box cookers don't heat quickly, they provide slow, even cooking. They are also very easy and safe to use, and fairly easy to construct.
Parabolic cookersThese reach higher temperatures and cook more quickly than box or panel cookers, but are harder to make and use. Most commercial solar ovens are of the parabolic variety. Parabolic cookers require more precision to focus the sunlight on the cooking vessel. If the sunlight isn't focused exactly, the food will not cook. More expensive versions have a built-in tracking device which automatically follows the sun; other the tracking has to be done by hand.
