Conical Cooker

The Conical Cooker consists of a piece of iron that is bent into a cone shape and is covered on the inside by reflecting foil. Inside the cone there is a platform of blackened iron on which a blackened pan is placed.
The sun rays reflect from the foil onto the pan and platform, which absorb the radiation and thus are heated. Putting a transparent sleeve or plastic bag around the pan, or a transparent cover above it, yields higher maximum temperatures and thus faster cooking.
When using a conical cooker with a diameter of 80 cm, liter of water can be brought to boiling in about 20 minutes. While cooking food, temperatures in excess of can be reached.
A later version is tilted 20 degrees to one side so that it can also be used when the sun is at a low angle in the sky.
