Is there a fundamental energy or entropy cost of moving matter around? If I
want to send a mass M from point A to point B within time T, how much would
Fundamental energy cost, yes, easily derived. But entropy cost, I don't
think there is an enherent entropy cost. Do let me ponder and derive, and
get back with you later on that Anders. Terrific question!
