The goal is to have an even spin that provides constant gravity so people don't bounce around the inside. If you have uniform gravity, then the river will not flow anywhere but down hill, and getting it to go back uphill will not work with just the spin. | |
Sep 28, 2017 at 20:53 | comment | added | rek | As an O'Neill-style habitat there is energy in the form of spin, which produces spinward and outward (down, from the perspective of the inner surface) motion from anything not held to the surface. There's also heating in the form of a simulated day/night cycle, but I don't expect that to factor. | |

Sep 28, 2017 at 18:21 | comment | added | Brythan | There is no such thing as centrifugal force in these systems; there is only angular momentum and centripetal force. Combined, the two give the illusion of centrifugal force and what is called the Coriolis effect. The question here is if the angular momentum can cause a river to flow. Note that if this works, the water would almost certainly flow the opposite direction from the spin. The water would be attempting to stay stationary while the ground revolved underneath it. | |
