An afterthought was steam up and down stripping pumps. More of us would know what was (is?) used than for propulsion or generators.
I was told that the reason the Kensington Science museum ran it's steam exhibits on occasional operation of electric motors rather than compressed air was because the expansion facilitated condensation and, in turn, corrosion. Unless these exhibits are to be run on a realistic duty cycle will that not be a problem this way as well?
(That now begs the question of lubrication if on compressed air. Perhaps that was also part of the story).
