- 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.
