I don't think termal shock is ever a problem.
I mean if you have a fire, ever a large one,
it only takes one blast with a CO2 to put
it out. I don't think you need to turn your
turbine into a ice cube.

Besides I have talked to Han (AMT designer) and
he told me he took a water hose on full blast
after a running Olympus and could not make it
quit and mess it up.
