Situated in the region of the focal line of an elongate liquid lens (22) are two concentrically arranged pipes (36, 38). The outer pipe (36) is transparent and the inner pipe (38) absorbs the concentrated solar radiation incident upon it. Both pipes are arranged in a cutout (44) of a collector (24). The collector is connected to the liquid lens by a frame linkage (30, 50, 66). The frame linkage is pivotable about two axes (52, 60) in order that the liquid lens can track the position of the sun. The liquid lens comprises a lower plane transparent plate (28) and a curved transparent plate (26). Situated between the plates is a liquid (31) which lets the solar rays through. A liquid, which has a lower boiling point than the liquid which is guided through the inner pipe, is guided through the outer pipe. The liquid in the outer pipe serves for hot-water preparation while the liquid in the inner pipe serves for preparing steam. <IMAGE> |
