In this instance, you are starting with mechanical movement, converting that via a pump to hydraulic motion, then back again to mechanical motion.
It sounds like an unnecessary and wasteful way of transferring mechanical motion to mechanical motion.
In your diesel engine, your reciprocating motion of the piston is converted to rotational motion by a con rod and bearings. I can't see why they can't do something similar here.
It would be a shit diesel engine, if the piston drove a pump, which pumped hydraulic fluid, which had to drive the flywheel. Nobody does it that way, because it's inefficient.
The benefit of this system, which is essentially a "wobble pump" is that it converts relatively small mechanical motion, which is amplified by the lever arm of the stalk, into energy that can be transmitted a distance and then used to generate electricity.
For example, look at a hand powered bilge pump. It has a long lever but moves the diaphram only a small distance to take advantage of lever-based mechanical advantage. In theory the output of that pump could be used to turn a turbine some distance away by pumping water through a hose.
In this device there are a couple of ways to harness the "wobble," one of which is to use the mechanical advantage of the lever arm of the stalk to drive a high-pressure hydraulic pump that pressurizes a reservoir which is used to drive a hydraulic motor that spins a generator. It's a way of turning reciprocating motion into rotary motion. Clearly there are system losses from friction, heating, etc., but since the energy input is free, inefficiency of this kind is less important than it is when there is a cost to providing the input energy as there is in coal, gas or nuclear plants.
Or, rather than using rotary motion, the short end of the stalk could be coupled to a reciprocating high-power magnet moving back and forth inside a stationary coil, like those "shake weight" LED flashlights you can buy. This translates the wobble of the stalk very directly into electrical energy which can be transmitted and combined to provide useful voltages and amperages.
I think it's a brilliant concept.
In fact, since the system uses high-power magnets as the "return force" that forces the stalk back upright after a "chain" of vortexes has pushed it off-center, one need only wrap a coil about the magnets that move that are attached to the stalk and get voltage directly from the motion. Brilliant.
