The spinning space-station is very popular in sci-fi as a means of emulating gravity in space. But it requires rather a large diameter to minimise "gravitational gradient" effects and that means such a structure has to be large.
An alternative is two 'pods' with a rigid 'pole' which can be set spinning so that each pod has gravity for habitation while the pole is used for storage/etc. But even so, it's still a big structure.
So what about two pods tethered by a rope instead of a rigid strut? Suddenly the extra materials to get the whole thing spinning are quite small. Is this feasible or do the pods have to be connected by a rigid strut to stop them moving inwards or becoming erratic in movement?
