US Patent 10060299 Thermo-elevation plant and method

In some aspects, a thermal elevation system includes a base plant including an evaporator to vaporize a working fluid. A lift conduit is coupled to the base plant and includes multiple lift stages to lift the working fluid in the vapor state. An elevated plant is coupled to the lift conduit and condenses the working fluid at the elevated plant. A power generation conduit is coupled to the elevated plant and flows the working fluid through multiple power generator stages that each generate electrical power. The working fluid may return to the base plant for recirculation.
