I think the standard should be "plausible" not "definitely doable".
I have jury rigged B-17 superchargers for use as steam turbines by blocking off a 270 deg arc of blade/vanes and plumbing steam into whats left. Got the things to 20,000 RPM and about 100 hp.
Less steam and it would still work with the right nozzle area.
Let me loose in a wreckage field and I can propbably get something working.
Necessity is the mother of invention.
