  • Publication number: 20240171055
    Abstract: The present invention discloses a magnetohydrodynamics power system which utilizes low temperature heat source. Variable control of the operation of the system, along with determining configurations for specific cases, are made possible by selecting the refrigerant, liquid metal circuit geometry, and by adjusting the system condensing pressure and/or temperature. Adjustable condensing pressure and/or temperature allows the system to react to changing ambient temperature and maximize power output. Adjusting condensing pressure and/or temperature of the system is made possible with a variable condenser pressure controller. The variable condenser pressure controller allows utilization of the physical properties of the refrigerant over a wide range of condensing temperatures/pressures, including pressures in the vacuum range.
