<p>This invention relates to a solar chimney arrangement, and in particular to an arrangement which includes a chimney (11, 31) to receive fluid originating from a solar heat collector (7, 27, 6, 26) and a turbine (2, 32) to be driven by the fluid. The solar heat collector has an evaporative area (6, 26) and a non evaporative area (7, 27), the non-evaporative area acting as heat absorbing area and having a first cover (8, 28) adapted to inhibit evaporation of a heat-absorbing liquid retained therein, the evaporative area having a second cover (4, 24) connected to the chimney and adapted to contain vapour evaporating from a liquid in the said evaporative area, there being means to transfer thermal energy from the liquid of the non-evaporative area to liquid of the evaporative area. The solar heat collector increases the moisture content and the temperature of the air flowing past the turbine.</p> |
