Actually I like this idea a LOT. I do not know how about the ferrofluids but the idea of viscous drive sound very attractive… Pretend we have a stationary fluid dispenser that tosses a steam of fluid on the wall (perhaps internal) of the platter. Visualize a fire hose with termination of some kind of jet proportion accelerator. So, the stabilized flow of the fluid hits the wall of the rotational platter at angle of let say 30 degree. By the tension between the jet of fluid and the wall (the wall might have some granularity of vertical texture) the spinning moment is created. The fluid is collected then, return to the pump and injected back to the jet dispenser. We could read the rotations speed of the platter and change the voltage on the pump, introducing the self-regulating servo stabilizing. Funny but the fluid by the nature of given propulsion will serve as a perfect decupling mechanism of this servo stabilizing loop. Do you want to do kinky? Well, let load this type of fluid drive with oil and then as we settle at cruse speed let to heat up the oil, reducing its viscosity…
