A solar cooker uses the sun's energy to cook food by reflecting and concentrating sunlight using a shiny reflector, often in a bowl shape. To build your own, you need a shiny reflector surface to direct sunlight onto enclosed food to contain heat and speed up cooking. Using a black pot absorbs more heat than a lighter one.

3. Build Your Own Solar CookerYou need a shiny surface to reflect and concentrate the Sun’s energy on the food.It is good to have an enclosure around the food to contain the heat. This prevents hot air from escaping. This will raise the temperature and speed up cooking time. The enclosure needs to be transparent so sunlight gets in. If you are using a pot to contain your food, it is better to get a black one. A black surface absorbs more heat than a lighter-colored surface.
