Power system with carbon dioxide working fluid

A power system, configured to generate mechanical energy from subcritical and supercritical carbon dioxide in a closed loop;

• the power system comprising:
• a compressor configured to increase a pressure and flow rate of the supercritical carbon dioxide resulting in a high pressure supercritical carbon dioxide;
• a heat exchanger, operatively connected to the compressor and to a first manifold through a pressure differential orifice;
• wherein the heat exchanger is configured to cross a hot carbon dioxide stream from the compressor and a cold carbon dioxide stream comprising a low pressure low temperature subcritical carbon dioxide from the pressure differential orifice resulting in a high enthalpy supercritical carbon dioxide that is delivered to a second manifold;
• a rotary engine, mechanically coupled to the first manifold with a check valve at an exhaust port;
• wherein the rotary engine is further mechanically coupled to the second manifold with a first electronic compression injector at a first injector port and a second electronic compression injector at a second injection port;
• and wherein the rotary engine is configured to convert pressure and flow from the high enthalpy supercritical carbon dioxide into mechanical energy and an output supercritical carbon dioxide;
• wherein the pressure differential orifice is operatively coupled to the rotary engine and to the heat exchanger and configured to decrease the temperature and the pressure of the output supercritical carbon dioxide resulting in the low pressure low temperature subcritical carbon dioxide;
• wherein the low pressure low temperature subcritical carbon dioxide is heated in the heat exchanger and then enters the compressor completing the closed loop.
