Hi guys, I saw this problem today and the solutions was not obvious to me, especially because I believe it is not clearly stated. 1. The problem statement, all variables and given/known data Consider a scheme in which thermal enrgy is extracted from the ocean. Some of the extracted energy is used to perform mechanical work(run the ship) and the rest is discarded back into the ocean. Why will this not work? 2. Relevant equations 3. The attempt at a solution Thank you!
