What is the working of solar cooker?
Solar cooker works on the principle that sunlight warms the pot, which is used for cooking the food. Now, this warming of the pot occurs by converting light energy to heat energy. Concave mirrors are used in these types of cookers because these mirrors reflect sunlight into a single focal point.
What is solar cooker PPT?
COOKING PRINCIPLE Solar cookers are passive solar devices. Sunlight is converted to heat energy which is retained for cooking. Solar cookers utilizes the simple principles of reflection, concentration, absorption and greenhouse effect to convert sunlight to heat energy.
