A solar cooker is an eco-friendly and efficient cooking device that harnesses the sun’s energy to cook food. It uses solar radiation to obtain heat onto a cooking vessel, thus allowing food to cook without any emission of greenhouse gases or pollutants. They’re ideal for rural communities, slum dwellers and refugee camps; where access to fuel is limited with heavy reliance on traditional cooking methods such as three-stone fires and charcoal stoves. It can save upto 50% of household energy costs.
