Abstract
A power generator including a closed pressure resisting tubular loop having a lower warmed end and an upper cooled end joined by connecting penstock column and a return column, the tubular loop being filled with fluid under pressure, the critical point of which is between the temperatures of the cooled and warmed ends, to cause the fluid to convert to a liquid phase in the upper end for discharge into the penstock column, and cause the liquid to convert into a gas phase in the lower end, for discharge while in its gas phase into the return column so that circulation of fluid as it converts between its liquid and gas phases is continuous, and a hydraulic power unit driven by downwardly moving liquid in the penstock column, reacting to the hydrostatic pressure so generated.
Claims11
A power generator, utilizing a lower region maintained at an upper temperature, and an upper region maintained at a lower temperature, the power generator comprising:
- a. a tubular closed loop system including an upper zone at said upper region, and a lower zone at said lower region, and a penstock column and a return column connecting the zones to complete the loop system;
- b. a fluid under pressure sealed in the loop system, the fluid being at a preselected upper pressure and temperature at the lower zone and at a preselected lower pressure and temperature at the upper zone, the fluid having a critical gas-liquid conversion pressure temperature between the pressure-temperature at the lower zone and the pressure-temperature at the upper zone;
- c. a condensing heat exchanger at the upper zone for converting said fluid from a gaseous state to a liquid state for movement of the fluid in a liquid state into the penstock column to create a liquid head causing downward movement of the liquid therein;
- d. an evaporating heat exchanger at the lower zone for converting said fluid from a liquid state to a gaseous state for movement of the fluid in a gaseous state up the return column, whereby continuous circulation of fluid is maintained in the loop system;
- e. and at least one hydraulic motor is positioned for engagement by the liquid phase moving in the penstock column.
A power generator utilizing a lower region at higher ambient temperature and an upper region at lower ambient temperature, the power generator comprising:
- a. a tubular closed loop system, including an upper zone disposed at said upper region of lower ambient temperature, a lower zone disposed at said lower region of higher ambient temperature, a penstock column and a return column connecting the upper and lower zones;
- b. a pressurized fluid completely filling the loop system and having a critical gas-liquid conversion pressure-temperature intermediate the ambient temperatures and the pressures at the upper and lower zones of the loop system;
- c. a first heat exchanger at the lower zone for converting the pressurized fluid from liquid to gas for discharge into the lower end of the return column and upward movement therein;
- d. a second heat exchanger at the upper zone for converting the pressurized fluid from gas to liquid phase for discharge into the upper end of the penstock column and downward movement therein;
- e. and at least one hydraulic motor positioned for operation by the liquid phase fluid moving in the penstock column.
