NOVELTY - The system (1) has a venturi nozzle (30) including an inlet section (30a) to receive fluid downstream of a heat exchanger unit (3) and an outlet section (30b) narrower than the inlet section. The output section is connected to an inlet (15) of a hybrid compressor (11) to produce pressure drop and corresponding increase in speed of a gaseous component e.g. argon or nitrogen, to favor formation of bubbles-of-the gaseous component that hit against blades (14) of an impeller (5) in use after being flown through a turbine chamber (7) to cause the blades to rotate.    USE - Low-enthalpy heat source supplied electric energy generation system for use with furnaces or chemical reactors for industrial applications.    ADVANTAGE - The system is easily adaptable to operate efficiently even with supplied high-enthalpy heat source, and can adopt simple changes that allow the fluid to be kept at low enthalpy of solar or geothermal energy for adjusting the compressor to increase flowing speed of the fluid in the heat exchanger and an oversizing chamber in an easy and cost-effective manner. The compressor is arranged with an outlet facing upwards and underneath a turbine in a position vertically aligned with a radial inlet of the turbine such that the venturi nozzle is in vertical position, so that the venturi nozzle is not obstructed, while favoring upward movement of bubbles of gas due to hydrostatic thrust or injection of the bubbles of gas into the turbine. The system allows a liquid component, which consists of water and additives to prevent oxidation and decay of various parts of a fluid flow-circuit.
