the solar cooker "Papillon"

How does our Solar-Cooker works?

Our Cooker focuses the in falling Solar Energy in one area ("Focus"), in which the cooking utensils are fixed. To keep the focus the mirrors follow the sun on a two-axled. This happens on the one side by moving the fork on which the mirrors are fixed, on the other side by repositioning the entire Solar Cooker.
Is the Cooker not in use, the mirrors are closed into a vertical position. This makes a compact measurement possible.
