Abstract: A hydroturbine engine device having a plurality of notched discs mounted within a high pressure fluid chamber. A high pressure oil input is provided along the edges of said discs at one portion of the unit and an outlet for the spent oil is provided downstream thereof and adjacent thereto. The discs are keyed to a center driven shaft for connection to a work output. The turbine engine is connected to a high pressure oil pumping unit which supplies oil at high pressure to the input of said turbine engine. The turbine engine is also connected to an electrical alternator which in turn is connected to a storage battery through a voltage regulator system. The storage battery is used to at least partially drive the electric motor for the hydraulic oil pump. Thus, a portion of the energy output of the turbine engine is utilized in a feedback system for the oil pump to partially supply the source of hydraulic oil pressure for the turbine engine.
