I think one of the things that would affect a flywheel more than a turbine is the pure size of the thing, as having such a large diameter compared to the turbine would send the centripital forces through the roof. Also an unbalanced turbne wheel probably wouldnt make it to 100,000 rpm, wouldnt the extra load on the bearings slow it right down?
