    "goal": "Convert inertial impulses from high-energy cosmic particles into usable electric currents.",
    "problem_addressed": "Provide an inexhaustible, clean energy source to replace fossil fuels and reduce environmental impact.",
    "concept_summary": "The HEED treats the Earth's outer layers (magnetosphere, ionosphere, etc.) and the Earth's surface as the plates of a gigantic capacitor with the troposphere acting as the dielectric. Random pressure waves generated by impacts of solar wind and other cosmic particles cause minute variations in the effective plate spacing, producing voltage fluctuations. A resonant LC circuit (parallel or series tuned) coupled to a conductive surface in the troposphere harvests these voltage changes, stores the energy, and releases it via a spark gap or resistive load, thereby generating electricity.",
