But if one were to use magnetic bearings with closed loop feedback 
compensation, one could deal with this.  Straightforward technology 
used in, oh, gas centrifuges, among other things.  TC RSGs spin a lot slower.

Not that it's reasonable for the run of the mill tesla coil, but just 
thought I'd throw it out there for the ambitious experimenter.  There 
is a substantial commercial market for this kind of thing if you come 
up with clever ways to do it.
