Is this "motorized" I don't think so. A water powered water pump, one of my early builds in the late 1990s.
A prototype made from old bike parts and ABS pipe for turbine blades.

We are only limited by our imageination.
I have a water powered floating generator on the drawing board now.
It will be able to power a 2500GPH electric water pump.
If you camp near it it will run your camp all night long or let you run lights, and mine all night long.
No Gas, the river never stops or gets tired.
Since I can't use my 4" dredge I might re-purpose the pontoon frame to carry a waterwheel and generator.

The old timers invented the sluice. We are making better mining gear as we speak.
We will always find a way to mine.
