Conversion of supercritical water energy into electrical power

A system for producing electrical energy from high-temperature, high-pressure liquid, the system comprising:

• a reactor configured for combusting fuel at a temperature of greater than 374° C. and at a pressure above 3210 psi and producing high-temperature, high-pressure liquid as a byproduct of the combustion of the fuel;
• at least one vessel having one or more walls that define a hollow interior cavity configured to be partially filled with water at a temperature of less than 100° C., with an air pocket within the hollow interior cavity above the water in the hollow interior cavity, wherein the at least one vessel includes a high-pressure water outlet port and a high-pressure water inlet port;
• a plurality of valves configured to control admission of high-temperature, high-pressure liquid from the reactor directly into the air pocket through the high-pressure water inlet port such that the high-pressure liquid flashes to steam upon admission to the air pocket when the air pocket has a pressure lower than an operating pressure of the reactor and to control emission of the water from the at least one vessel through the high-pressure water outlet port after the water in the at least one vessel has been pressurized by the admission of the high-temperature, high-pressure liquid from the reactor into the air pocket;
• and
• a hydroelectric drive system configured for receiving water emitted from the hollow interior cavity of the at least one vessel through the high-pressure water outlet port and for converting energy in the received water into electrical energy;
• and
• a de-sanding cyclone configured for receiving liquid receiving water from the hydroelectric drive system and for removing solid byproducts of combustion of the fuel and for supplying water without the removed solid byproducts to the at least one vessel.
