    3D Geometry of a solar parabolic reflector composed of flat lamellae

     This is how the 3D-layers of compressed light look like in the case of a parabolic reflector composed of flat lamellae(petals). For illustration is considered the computer built light-structure of a 12-petals-reflector, with D=800 mm, f=100mm, bottom opening 120mm.Depending on the position relative to the focal plane, the adjusting between...

    Cooking and frying with the parabolic cooker are performed in ordinary commercial metal pots – usually from steel (Inox) and aluminium. Recommendable with thick thermo-bottoms. Also being used are thin-wall enameled steel pots without thermo-bottoms. Thin-wall cookware distributes the heat worse than thick-wall, so that could the food be burnt...

    Focusing of a solar parabolic cooker

    Focusing of a Solar parabolic cooker consists in targeting the reflector to the sun in such a way that the axis of the reflector is parallel to the direct sunlight. When this is fulfilled, the device is so designed, that the bright spot of the focus falls within the area of the supporting grid(supporting ring). In this sense, as synonyms are...
