Abstract: A portable hydro-generator, for the generation of power, including a tower (10) filled with a driving fluid, a semi-sealed curved tubular housing with a drive portion and a return portion primed with a fluid, the drive portion having a larger diameter than the return portion, an inlet to allow the fluid to enter the tubular housing, a plurality of paddles to harness the kinetic energy of the fluid entering the curved tubular housing, a linkage assembly to link the plurality of paddles, a drive chamber, a sprocket within the drive chamber to engage a portion of the paddles, and an output power generator attached to the sprocket. A paddle adapted to be used in the hydro-generator include a top surface, a bottom surface, seals to prevent water leakage through the paddles, a linkage bar to allow an attachment of the paddle to subsequent paddle, wherein the top surface of the paddle further includes studs to increase the effective surface area of the top of the paddle.

Abstract: A portable hydro-generator (100), for the generation of power, including a tower (10) filled with a driving fluid (110), a semi-sealed curved tubular housing (80) with a drive portion (81) and a return portion (82) primed with a fluid (70), said drive portion (81) having a larger diameter than the return portion (82), an inlet means (60) to allow said fluid to enter said tubular housing (80), a plurality of paddles (30) to harness the kinetic energy of the fluid entering the curved tubular housing, a linkage assembly (34) to link said plurality of paddles, a drive chamber (83), a sprocket (50) within said drive chamber (83) to engage a portion of said paddles, and an output power generator attached to said sprocket.

Abstract: An engine comprises a rotary unit (1) and a reciprocating unit (3) coupled to a common drive (7). A first rotary unit (1) provides the induction phase of the 4-stroke cycle and passes air to the reciprocating unit for the compression and combustion phases. The exhaust gases are passed to a second rotary unit (5) having an afterburner for the exhaust phase. Alternatively, two rotary units and two reciprocating units each having two pistons may be arranged alternately. The invention may also be utilized for improved 2-stroke engines making one power pulse per stroke.
