    "goal": "Generate electrical power from sunlight using a thermoelectric effect and sustain a pendulum-based power system for long-term home energy supply.",
    "problem_addressed": "Provide a low-maintenance, long-duration power source for homes without reliance on conventional fuel or grid electricity.",
    "concept_summary": "The invention uses alternating series of dissimilar metal plates or pipes (e.g., copper-aluminum or copper-iron) that are heated by sunlight on one side and cooled by water or ground on the other, creating a temperature differential that produces a voltage via the Seebeck effect. The generated electricity powers a pacemaker circuit that periodically energizes a magnetic coil to give a \"kick\" to a swinging pendulum. The pendulum contains an ionic solution that, when agitated, also produces electricity, providing make-up power when solar input is insufficient.",
