Simple Solar Cooker Designs

solar cooker
A device that converts the sun's energy into heat energy, which is then used to cook food.
A solar oven or solar cooker is a device which uses sunlight as its energy source. Because they use no fuel and they cost nothing to run, humanitarian organizations are promoting their use worldwide to help slow deforestation and desertification, caused by using wood as fuel for cooking.
