  • Water circulation apparatus to reduce evaporation
    Patent number: 7465123
    Abstract: A natural water circulation apparatus reduces the evaporation rate of a body of water by lowering the surface temperature and improves the quality of the water. The apparatus includes a collector which extends above the normal surface level of the water to capture surface waves. The captured water is conveyed from the epilimnion of the body of water to the hypolimnion of the body of water through a lower opening in the collector.
