text: Clearly mechanical systems need energy to do work, and the energy needed comes in two different kinds:
text: Instead, the energy to do work comes entirely from thermal energy, and (as in the case of an expanding ideal gas) only the positive entropy change of the polymer allows its internal thermal energy to be converted efficiently (100% in theory) into work.
