    "goal": "Generate thermonuclear energy (heat) via acoustic cavitation of liquid metal.",
    "problem_addressed": "Provide a method to produce net energy gain using fusion reactions without conventional high-temperature plasma confinement.",
    "concept_summary": "Acoustic horns induce pressure waves in a sealed chamber containing a liquid metal (e.g., lithium, beryllium). The pressure variations create cavitation bubbles that grow and collapse violently, causing adiabatic compression that raises temperatures and pressures enough for hydrogen isotopes (deuterium, tritium) to undergo fusion. The resulting heat is extracted through the acoustic horns to an external heat exchanger.",
