that is very cool - too bad the log is not being advanced against the blade

In Wilmington DE there is the site of the original DuPont gunpowder mills.  They
have water turbines instead of water wheels - installed before the civil war.
These are about the size of a 50 gallon drum, have a sealed top to hold the
pressure in, and spin at an amazing rate - I could only find this short video
and it is not very dramatic because you can’t see the turbine:

It may be turning at 3 or 400 RPM, and the 2 shafts each go to a set of rolling
mills that must weigh a couple of tons each:

They also have a civil war era machine shop run with line shafts driven by a
giant turbine (8 feet across).  A site to behold in operation:
