What if it isn't air, but an actual fluid, e.g. water? It cannot be compressed, so it's "crash proof" (carriages cannot hit other carriages with water in between). It also has plenty of mass, so once it has started moving, it will push carriages around easily. A torus with permanently moving water (probably a more high-tech fluid), where carriages are injected / removed after acceleration / before deceleration?

- graeham 14y agoBoth liquids and gasses are fluids and drag is worse in water than air, so the energy required would only be higher. Consider: is it harder to push your hand through the air or a tub of water?
