There is no way to increase the rpm without gaining more head, or getting a smaller diameter runner. He is running the hydro at 12 volts, so the 12v rotor is fine. Switching to the 24v stator is just like winding an axial for lower cut in. There will be more I^2r losses in the stator windings, but it should be far offset by the lowering of the field current at his low output. there is also the possibility of using an Mx-60 to find the max power point, but there is the problem of huge inductive surges with the wound field when the mx60 unloads the turbine. Those surges don't happen with a PM alt, the voltage just doubles as the rpm doubles. (pelton runners typically have their max power when the cups are at 50% of jet velocity)
