Solar Cooker The advantages of the solar cooker is that it provides its own electricity due to the light given by the sun. In countries such as Africa, this can be extremely helpful, as they all not have access to electricty, or even clean water. In order to have clean water, it has to be boiled. Also this is easy to use, and everyone can use it. Humanitarian organizations have prometed their use in the whole world, as they can be cheap, they are ecol friendly, and could save a lot of time and people. This is eco friendly as it prevents deforestation and desertification, by cutting less wood to be used as fuel for cooking.
