This idea was successful enough that power-only water networks were
established in few places, to running motors without wasting large
amounts of potable water:

I'd not heard of that. Very interesting!

Truly there is more than one way to do it.

Reading a little further, one sees an actual water-powered sewing
machine motor, complete with drip tray for leaks:

To get closer, if not quite on, topic, lots of material on the
applications of stationary bicycles:

Many, many years ago, James McCullough (sp?), then editor of Bicycling magazine,
edited a book on human powered contraptions. It touted things like pedal
powered lathes and plowing fields by using a pedal powered crank system to reel
in a cable that pulled the plow across the field. It didn't seem to transform
society.

The author noted that when slavery was legal (as it was in most human societies
at one time or another) slave labor was preferred over animal labor for power
production. His explanation was that humans are more efficient than draft
animals, in terms of work out vs. food energy consumed.

I've read that the English prison systems had "treadmills" that the
prisoners were forced to power. See
