A solar cooker is a device that uses sunlight to cook food. It typically consists of reflective surfaces that concentrate sunlight onto a cooking pot, allowing it to heat up and cook the food inside. Solar cookers are eco-friendly and do not require fuel, making them a sustainable option for cooking. There are various types of solar cookers, including box cookers, parabolic cookers, and panel cookers. Each type has its own design and efficiency level, but all rely on the sun's energy. Solar cookers are especially useful in areas with abundant sunlight and limited access to traditional cooking fuels.
