  • Systems and methods for power generation based on surface air-to-water thermal differences
    Patent number: 10472033
    Abstract: A system includes a vehicle having a body and a power generation system. The power generation system includes first and second tanks each configured to receive and store a refrigerant under pressure. The power generation system also includes at least one generator configured to generate electrical power based on a flow of the refrigerant between the tanks. The first tank is configured to be cooled by one of ambient air and water to a lower temperature, and the second tank is configured to be warmed by another of the ambient air and the water to a higher temperature. The first tank or associated heat exchanger can be positioned such that the first tank is above the water's surface when a portion of the body breaches the surface. The second tank or associated heat exchanger can be positioned such that the second tank is below the water's surface when a portion of the body breaches the surface.
