PROBLEM TO BE SOLVED: To provide a power producing device for taking out a power from a heat source with room temperature such as the sun. SOLUTION: This power producing device comprises the systems of a heat engine in which a peripheral fluid with room temperature is used as the heat source, the heat of fusion of ice is used as a cooling source, and refrigerants (ammonia, propane, CFC 21) are used as working fluids. A thermal efficiency is increased by the cogeneration of cooling and the use of solar heat, namely, by adding a double effective system of a cold heat source in which approx. 50% of a latent heat in temperatures between 0°C after the melting of the ice to the temperature of the heat source is used again for power generation. The power producing device is mounted on the marine engine of a hull apparatus. Ice consumed in the power producing device is taken from a sea water in arctic region into an ice container and transported to consuming sites by a tow ship. The ice container can easily transport the ice at low cost. COPYRIGHT: (C)2006,JPO&NCIPI
