I have a mechanical engg. question that I could ask my dad but he's 7 hours ahead of me Consider this zany contraption Would it take less energy to drive the last gear underwater than it would above? Can we construct a gearbox that arbitrages gravity?

ah damn...liquid resistance.... In principle tho if there were a gravity differential between the ends of the gearbox, are we doing something interesting or am I misunderstanding something other than basic laws of thermodynamics?

Gravity is kinda irrelevant here. Inertia is rotational. I don’t see what you’re getting at tbh. Something like a space elevator arbitrages gravity in a way.
