EpsilonStudios: It would work irl. You would probably need a LOT more surface area for the stones than the water but you don't need to heat the water.
@EpsilonStudios would probably work if stones were pushing a piston which would force a gas to another piston that pushes water
from a real life standpoint, generating power with this wouldn't be very effective, it would generate power but not enough to power the actual mechanism, you would need to add energy to the water (heating it up, maybe about 200c)
ID:2524389 is similar, although I did not realise this was powerful enough to lift water.
how the hell?! i invented this pump! nice though
just make sure to replace watr with dstw to prevent unwanted consequences
add detector wall for INFINITE POWER!!1!!11!
Made one without walls id:2927703
