    "problem_addressed": "Lack of accessible fresh water for populations in arid or remote regions",
    "concept_summary": "A wind-driven motor powers a refrigeration circuit that cools an evaporator. Air forced over the evaporator condenses water vapor, which is collected and stored. When wind stops, a secondary energy source can continue the cooling cycle.",
    "detailed_description": "The system consists of a mast-mounted turbine that drives a compressor and a cooling loop. The loop circulates a refrigerant through an evaporator exposed to ambient air. As the refrigerant absorbs heat, the evaporator surface temperature drops below the dew point, causing water vapor to condense. Condensed droplets run into a storage tank within the mast. A backup power source can operate the compressor when wind power is unavailable.",
