ABSTRACT:
Apparatus to convert the internal energy of hot fluids to mechanical work comprising a pair of nozzles, e.g. convergent-divergent nozzles, mounted oppositely on hollow support arms which are in turn mounted on a rotating hollow shaft which is coupled to a conventional electric generator or other device requiring mechanical power. The hot liquid, e.g. hot brine, flows through the hollow shaft and the hollow support arms to the nozzles, where the hot fluid expands and creates a thrust and torque on the shaft, causing it to rotate and create shaft power. The nozzles and rotating shaft are mounted in a closed container from which the exhaust fluid, gases and liquid are removed by conventional means so as to maintain a reduced pressure within the container.
