Is it physically possible [even though it might be impractical to actually carry out] to drive a ship across the ocean by using the thermal energy in the surface waters of the ocean? That is, could this be done without violating any principle of physics?
A) No, because there is no thermal energy in the ocean.
B) No, because this process would violate the second law of thermodynamics.
C) Yes, by exhausting the unused thermal energy into the stratosphere or into the deep ocean, where the temperature is cooler than that of the ocean's surface.
D) Yes, by exhausting the unused thermal energy into Earth's lower atmosphere, where the temperature is warmer than that of the ocean's surface.
E) No, because this process would violate the law of conservation of energy.
