Question

State any two advantages of a box type solar cooker.

Answer 1

The solar cooker is a device that cooks food without using any conventional cooking fuel or energy like cow dung straw, wood, coal, gas kerosene, or electricity. It converts sunlight into heat energy and cooks food.
Advantages of a solar cooker :
As solar cooker does not consume any conventional fuel or electrical energy, it saves fossil fuels, wood, electricity, etc. which are otherwise required to cook the food. It does not emit any smoke or smell and hence does not pollute the environment. There is thus no chance of causing cancer and affecting eyesight or lungs. It does not require constant attention while cooking and hence saves time which can be utilized for some other productive work. As it is a slow cooking device, it preserves the nutritional value of the food. It can be used for cooking three to four items at a time. There is no possibility of causing accidents like catching fire, bursting of gas cylinders, electrical shocks, etc., and hence is safe to handle.
