A combustion-driven hydroelectric generating system has one or more combustion cylinders that contain a liquid (such as water) and receive a combustible fuel/oxidizer mixture that is ignited and the explosive force of the combustion acts on the surface of the liquid to transfer a metered slug of the liquid to a pressurized vessel containing a pressurized gas (preferably an inert gas). The pressurized liquid from the pressurized vessel serves as a “head of water” that can be used to operate a water wheel (Pelton wheel) or hydroelectric generator and perform other useful work. The transferred liquid is replaced in the combustion cylinders, another charge of the fuel/oxidizer is introduced and ignited and the process is repeated. Replacement liquid is introduced into the combustion cylinders through a closed loop system utilizing the exhaust of the combustion cycles to significantly lower the elapsed time period of each single cycle, and increases the production of power, efficiency of operation, and reliability.
