==== Interestingly, it might be more useful for “merely” long-range solar system logistics than for true interstellar generational ships: ====
* Within the solar system - You can exploit short-period comets (orbital periods of a few–tens of years). - You can have multiple depot-comets, forming a kind of sparse, moving logistics web in the outer system and Kuiper belt. - This helps support: - outer-planet colonies - Kuiper-belt mining - Oort-cloud science missions
* For interstellar generational ships - Once you’re well past the Sun’s deep gravity, periodic comets are mostly behind you. - You might intersect Oort Cloud objects, but: - their orbits are poorly constrained - they’re 3D random rather than a nice predictable 2D belt. - Using them as scheduled depots becomes much harder.

So the sweet spot is probably:

Think: a slow ark built to crisscross the outer solar system, topping up from comet-depots on the way, rather than a ship to Alpha Centauri.
