A solar-heat absorbing device comprising two elongate, thin, flexible lengths of material (41, 42) joined together along lines (44) in a manner such as to form fluid channels (45) between the material lengths. One of the material lengths (41) comprises a thin metal sheet, and the other (42), is made of rubber, at least along the joining (44), the rubber being joined to the other material length (41) by vulcanizing. |
