Solar ovens use heat from the sun to cook, clean, and disinfect different materials. Solar ovens are carbon-free, meaning that they do not omit green-house gases that harm the environment. Solar ovens can help developing countries cook food and save time. Instead of having to walk miles to get materials and do laborious tasks, solar ovens can save time and require little work to set up. Solar ovens only require the suns heat to begin the heating process. Sunlight and high temperatures may help speed up the heating of materials.
