So what ideas do folks have for using these? I was thinking they're
*almost* small enough to think about making something like a homemade
"flea" unit, like those powered trucks NWSL makes (still?) for HO.

I've seen one of these in a scratch built Nn3 Shay also had sound!!
WOW!! Way/Whey/Weigh cool. I've seen this a couple of GATS (or whatever
they are calling themselves now) shows. I can't remember the name of
the modular group he belongs to.

These things are almost as common as dirt:

It's going to need a very large gear reduction before it will do
anything useful and (multiple) worm/pinion reductions are inefficient
enough to use up all the available torque.
One could use multiple stage spur gear reduction between 2 or 3 shafts
but that's going to be a lot of very fine gears!
Perhaps it could drive Diesel loco fans with a rubber belt drive - I'm a
steam loco man.
