Abstract: A continuous fluid circuit electricity generating system for producing relatively expensive electricity without polluting the atmosphere or consuming natural resources. A first turbine submerged in a source of water (e.g., a man-made tank or a naturally-occurring well or larger body of water) supplies water under pressure from the source to a water propulsion turbine. The water propulsion turbine has a rotatable shaft coupled to the shaft of a first generator of electricity and a set of hollow impeller arms coupled to and rotatable with the turbine shaft. The impeller arms of the water propulsion turbine are located in proximity to a rotatable driven rotor having a coupling sleeve surrounding the shaft of a second generator of electricity. Water moving through and expulsed from the hollow impeller arms causes the impeller arms, the shaft of the water propulsion turbine, and the shaft of the first generator to rotate in a first direction.

Abstract: A multi-stage fluid power turbine having application as a fire extinguisher to be ideally carried by a fire truck (e.g., a tanker or a pumper) so as to fight outdoor fires. An impeller and a propeller are located at one end of the fire extinguisher, and a fan is located at the opposite end. The propeller and the fan are mounted on a common inner shaft so as to rotate in a first direction. The impeller is mounted on a hollow outer shaft or tube that surrounds the inner shaft. The impeller includes a plurality of curved blades, each of which having a fluid duct running therethrough. Water under pressure being supplied from a source to the impeller blades is ejected from the fluid ducts thereof and thrust against the blades of the propeller, whereby to impart a rotational force to the propeller and a corresponding rotational force to the fan. The water ejected from the curved impeller blades causes the impeller to rotate in an opposite direction.
