Hydraulic Generators
I notice that the newest high end Earthroamer has a hydraulic generator on board. I know that Earthroamer likes to talk about their vehicles not having onboard stand-alone generators. So I wonder ...

Wouldn't they have the same problem with a hydro system as well, unless they're using an electric pump instead of a belt drive? With gearing, belts, etc they can convert rpms up or down, but it still needs to be constant, still needs to be governed somehow?
I think they can govern it by altering the hydraulic fluid flow. I'm no expert, not even close, but I'm under the impression that many hydraulic systems are set up to operate at a more or less constant pressure (at least a constant static pressure), with something along the lines of a bypass valve at the pump end. If the load on the system is not constant, something of that sort is required or the pump would be locked and unable to turn until something broke loose...with messy results.
An inverter generator setup could certainly be used on a PTO or belted from an engine. At that point, it might be just as simple to put in a bigger alternator and an ordinary inverter, which amounts to much the same thing after all.
