There are lots of potential sites for micro hydro. Many where water

How much power can one of these produce, ...

Not a lot a few hundred watts at most. Not a big head and fairly low
flow. Say you have a wheel just ove 3m in dia and thus a 3m head and
17l/sec flow (or a tad over one IBC container full per minute) you get
around 300W of electricity...

and what do you propose be done with it?

Like Haryy does with his PV. Use it your self but also "sell" it to the
grid at 4 times the market price.

10 times the market price..Dave, ten times...
