The Scheffler-Reflector
The reflector is a small lateral section of a much larger paraboloid. The inclined cut produces the typical elliptical shape of the Scheffler-Reflector. That way the focus stays fixed, which is very useful, as it means the cooking-pot doesn''t have to be moved either. Since 1987 about 200 "small" solar-kitchens with 1 to 3 Scheffler

focus, the hot area where all light is concentrated, moves along with the direction of the sun. This makes its use a bit impractical. So about 24 years ago I started thinking of a design to make the hot focus available at a fixed place. This way the use of solar energy can be very convenient. With a fixed focus, also many more applications can be
