solar oven

solar oven, also called solar cooker, a device that harnesses sunlight as a source of heat for cooking foodstuffs. The solar oven is a simple, portable, economical, and efficient tool. Especially in the developing world, solar ovens are much to be preferred over other methods of cooking. Of the many advantages of solar ovens, the greatest is its freedom from the necessity for fuel. Solar ovens thus not only remove any persistent labour or monetary costs associated with cooking, but by conserving often scant resources in the long run they prevent deforestation and desertification. Solar ovens are also useful in the developed world whenever electricity is unavailable and traditional open fires are undesirable, such as while camping.

Types of solar ovens Solar ovens are available in many designs that employ an array of different materials and approaches. Each design must be capable of concentrating sunlight from over a wide area to a central point. At that central point, a black-surfaced vessel helps convert the sunlight into heat, which is used to cook the food. Further, once the heat is generated, it must be trapped and insulated from the cooler air outside the cooker. The basic designs are as follows: box cooker consists of a number of mirrored panels that focus their beams toward an insulated box structure, which has a transparent top used to admit the box cooker consists of a number of mirrored panels that focus their beams toward an insulated box structure, which has a transparent top used to admit the solar radiation . Black-painted cooking pots and pans are placed inside the box.

Parabolic cookers—which use a parabolic mirror to focus the sunlight to a central point at which the cooking container is placed—are capable of generating high temperatures, but they are more difficult than the box cooker to construct.

Panel cookers are the least-expensive type of solar cooker. The panels, often made of corrugated cardboard and covered with an inexpensive reflector such as aluminum foil or Mylar, focus the Sun’s rays onto a black cooking pot, which is kept inside an insulating plastic bag.
