I was looking at air motors and I don't see why some of the vane types
couldn't be used with steam. I had one apart a few decades ago (I don't
recall what it was being used for but it may have actually been a vacuum
pump) and the vanes were some kind of composite resembling fiberglass. The
only problem with the motor was the vanes were getting stuck in their
grooves and simply needed cleaning and lubrication. I didn't see anything
in there that looked like it would be really bothered by expansion due to
heat and if it was made out of the right materials the water oxidation
wouldn't be much of a problem. So guys, why won't it work?

Wouldn't fiberglass have a problem with steam temps?

A turbine that is missing from the above is the tesla turbine...
tesla claimed would work on steam....wet or dry....

Thanks for the interesting link. I'm still absorbing it. This make take
some time.
