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. These cookers come in various designs, including box cookers and parabolic cookers. They are especially useful in sunny regions where traditional cooking fuels may be scarce or expensive. By harnessing the power of the sun, solar cookers can help reduce reliance on fossil fuels and lower cooking costs for families.
