WXYZCIENCE has moved to a remote location and said he will be off-line for quite a while. If you check his diaries, or the "steam archives" post, you will find his stories.
I don't know of any commercial turbines, other than a wet-methane burning turbine adapted from a turbo that was used to generate electricity on oil rigs as a replacement for diesel-gens.
WXYZCIENCE is a machinist and made a single stage high-RPM turbine by mating two plates that had curved cuts on the edge, resulting in the 90-degree turn needed to get it spinning from a steam jet.
He also tried adapting a turbocharger to steam. I was interested in the PMA he built, he said he had to use a special wire (Litz?) to generate electricty when using high RPM's.
There are some turbines being used for a steam turbine of sorts that uses freon, called "Organic Rankine Cycle" (thanks, wdyasq!). From their web-sites, I got the impression they only sold whole systems, and they were very expensive.
