  • Patent number: 4342196
    Abstract: A method and apparatus for generating power and irrigating plants by using unlimited natural resources of solar energy and earth heat. The method and apparatus utilize various forms of solar energy and/or earth heat to produce pressure difference in two air-evacuated interconnecting chambers and to create periodic oscillation of the volatile liquid in said two chambers. The energy of the periodic oscillation of the liquid is used to lift water from a lower reservoir to an upper reservoir, thus creating a working hydraulic head. The water in the upper reservoir is then used to generate power or irrigate plants.
