    "problem_addressed": "The lack of a practical method to extract usable energy from the quantum vacuum (zero-point energy) without violating known physical laws.",
    "concept_summary": "A sub-micron optical (Casimir) cavity is placed on one side of a metal-insulator-metal tunneling structure. The cavity suppresses low-frequency vacuum modes, breaking the symmetry of zero-point fluctuations on the two metal sides. This creates a net flow of hot electrons across the thin insulating barrier, producing a measurable electrical current and power without an external voltage source.",
