Healthy foot made with solar energy
Imagine: it is summer, the heat of the sun is burning, and you are cooking your food with a little fire. Ok, you know it, right? it is a waste of energy.
Between spring and autumn we get so much solar energy, that it makes it really easy to get advantage of it for cooking.
There are different concepts for the making of solar kitchens, solar ovens, and water boilers. You can even build some models with 100% recycled materials.
