This is what laboratory ultracentrifuges do.  Usually the rotor housing
is contained in a thick bronze casing which "slowly" absorbs the kinetic 
energy.  I once heard an ultracentrifuge blow, and it sounded like a freight
train for maybe five minutes.  Lab centrifuges contain a surprising
amount of energy--even though they have relatively small rotors and big 
motors they take quite a while to get up to speed because so much has to 
be pumped into them.
