Probably. I think the coal-fired plants superheat the water to around 540 deg C; so the bearing/seal would likely work. And it is probably back-engineering since Hero was probably an alien . . . at least a hybrid. ;-) Then again, he did not have this issue: http://physics.kenyon.edu/EarlyApparatus/Thermodynamics/Heros_Engine/Heros_Engine.html
