It turns out that the axial tether and support may be insufficient for the stability of the torus relative to the wind turbine, the rope-drive transmission preventing a bridling of said torus, which is therefore not retained.
A new preprint was written, for a device linking the rope-drive wind turbine to a hydrogen-inflated aerostat protected by a layer of nitrogen or carbon dioxide (replacing the lifting kite), but without torus.
