    "publication_year": null,
    "device_name": "Marukhin-Kutienkov Hydraulic Ram",
    "goal": "Generate electricity and lift water without any external fuel or energy input, providing a self-sustaining power source.",
    "problem_addressed": "Dependence on fossil fuels, weather-dependent renewable sources, and the need for energy-intensive water-lifting pumps.",
    "concept_summary": "A submerged hydraulic ram uses the energy of falling water (gravitational potential) to create pressure surges (water-hammer effect). The surge drives a water-jet turbine or a piezoelectric converter, producing rotary motion that is turned into electric power. The system claims to operate continuously without additional fuel, providing both electricity and a high-pressure water jet for propulsion.",
