Solar cookers are devices that use sunlight to cook food. They capture and concentrate solar energy, allowing for cooking without traditional fuels like gas or electricity. These cookers can be made from simple materials, such as cardboard and aluminum foil, or more advanced designs using glass and reflective surfaces. There are various types of solar cookers, including box cookers, parabolic cookers, and panel cookers. Each type has its own method of focusing sunlight to generate heat. Solar cooking is an eco-friendly option, reducing reliance on fossil fuels and minimizing environmental impact.
