Smaller solar power plants have a round concave reflector (“dish”) with the working cylinder of a Stirling engine at the focal point. The generator is placed directly on the shaft of a Stirling engine. (Alternative: A permanent magnet is used as a piston, which as a linear generator can integrate the electric power generation directly in the Stirling engine.) Dish-Stirling power plants are used, for example, in sunny regions without a power supply grid as a partial replacement for diesel generators. If the power plant’s battery capacity is sufficiently large, the diesel generators can be dispensed with.
