Thermal Energy Scheme

  1. Sep 7, 2009 #1
    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!

    Just got a solution. It needs two energy sources, one hot and one cold. Should have thought more before posting it here...
    Sorry
