Abstract: An engine system includes three communicating fluid vessels that each contain a fluid. A first interconnecting fluid conduit containing the fluid rotatably couples the second fluid vessel to the first fluid vessel and acts as a lever. A second interconnecting fluid conduit containing the fluid rotatably couples the third fluid vessel to the first fluid vessel and acts as another lever. By increasing the fluid column heights in the communicating fluid vessels, torque is applied to the levers to cause the second and third fluid vessels to revolve around the first fluid vessel.

Abstract: A new power plant cycle facilitated by an innovative vapor compression apparatus to repressurize the air vapor and generate renewable energy for heat input to the cycle. The new cycle can be used in place of the conventional low efficiency Rankine cycle or other cycles to provide economical production of electricity without air pollution. The new cycle can also be used on-board land-based vehicles, aircraft, and watercraft to power them electrically or mechanically, or be used in a package unit for supplying electricity and controlling temperatures of indoor homes, business, and other structures. The new cycle can be used in Ramjet aircraft applications.
