I never understand why the rotating station concepts seem to all have rigid tethers, either in the form of a central boom or a rigid circular structure. It would seem like you could get a much larger diameter, so less rotational velocity and more comfort, by attaching rigid, or inflatable in this case, structures with a tether. Compressive loads are non existent, you just need to resist tensile loads.

Maybe I'll go ask the AI.

Stationkeeping would be a problem. And difficult to stop it precessing away from the rotation axis you want.

		An array of steerable ion engines hanging below the station (ie on the edge not in the center) can provide both reboots / stationkeeping and precess the axis, eg once per year to track the Sun. Because trig, by "mixing" both maneuvers together it uses less propellant vs doing the two maneuvers separately.
