    "inventor_name": "Larry Ford",
    "publication_year": 2008,
    "device_name": "Ambient Air Clothes Dryer",
    "goal": "Dry clothes without using heat to save energy and reduce fire hazard.",
    "problem_addressed": "High energy consumption and fire risk of conventional heated-air clothes dryers.",
    "concept_summary": "The ambient air dryer circulates a large volume of unheated ambient air through a rotating drum to tumble clothes, achieving drying times comparable to conventional dryers while using only low-voltage electrical power (110 V or 12 V) and optionally solar power. No dedicated heating element is used, eliminating flame-related fire hazards and reducing overall energy use.",
