Overcoming the Low Efficiency of Box Type Solar Cookers


The solar cooking is not so popular in India owing to the reason of prolonged cooking time of conventional solar cookers. The conventional solar cookers work on the principle of green house effect. Here the incident rays fall on the top of the lid which is usually painted with black. The delay can be attributed mainly to the air gap in the top portion of the utensil between the lid and the food. Convection loss also delays the cooking process. This paper suggests a cost effective Fresnel reflective concentrator to concentrate the solar beam to the bottom of the utensil.
