A system for obtaining air movement is disclosed which includes a basin of water covered by a solar energy-transmitting dome a spaced distance over the basin. The basin is located on a mountainside, adjacent a cliff, or the like. a surface type heat exchanger is located in the water adjacent the bottom of the basin, and an air inlet passage is provided having one end which terminates above the water surface beneath the dome and an opposite end connected to the heat exchanger. A long air outlet passage in the form of a flexible tube made of canvas, plastic sheet, or the like, is connected to the outlet from the heat exchanger, which outlet passage extends downwardly along the mountain slope, cliff, or the like. Venturi tubes are located along the air outlet passage, and vane-driven devices are positioned at the venturi tubes for operation by the cooled air flowing downwardly therethrough. An air valve at the bottom end of the air outlet passage controls the rate of air flow therethrough. The long air outlet passage is shielded from the sun to prevent solar heating of air flowing therethrough.
