Does this concept have any viability?
(OP)
Need to provide a large ratio > 1000x gear up.
Thought this might be a possible solution while offering the use of hydraulics for other purposes.
They always said think outside the box .. wondering if I belong in one ..

Can you get the parts to build a proof of principle thing for cheap?

So no, it has no viability.

doesn't look like a PMM to others ...

RE: Does this concept have any viability?
No .. I appreciate Conservation of Energy.
What I'm "considering" hence my desire for professional input is to "gear up" a water wheel to drive a PM Alternator.
If I assume worst case I need approx a 1:1000 ratio.
My thought was a multi sprocket drive train or reversed gear reduction unit would present heavy self load losses and high initial break torque. Then there's wear and tear.
Then I came up with this hair brained idea.
Conventional pumps produce insufficient flow rates at low RPMs so the use of cylinders as a pump
Based on just flow rates I "think" it may work, it also offers the advantage of use of hydraulics for other means .. log splitters etc.

I suspect that seal friction will drive you nuts, which is why I suggest prototyping one, as cheaply as possible.
Also take another look at roller chain drives. If they are kept clean and well lubricated, they can be very efficient.

You'll probably have to mount two sprockets on a jackshaft, or drill the hubs and bolt them together yourself.

Every inch-lbf of output torque loss will require 1000in-lbf to overcome.
My guess is that you have insufficient water pressure or flow. In hydroelectric systems the generators are driven at their operating RPM directly by a water turbine. I expect that beyond 2:1 to 4:1 the losses are high enough that changing the way energy is extracted from the water is worthwhile over the speed amplification losses.
This is well trod area. Search for "hydroelectric pm alternator"
RE: Does this concept have any viability?
In this context by easy I mean there will be a two way trade off, price and efficiency, but conceptually, there is no issue.
