Unfortunately Grimer I don't accept that the same weight/mass hung from wheels of different inertia's [but same turning moment] will experience different accelerations, experience different effective gravities, like anemometers in wind.
The acceleration from 'g' is constant & never changes, even when an object can't move or has stopped moving.
The
effective gravity changes in just the same way as the effective voltage changes when you apply a EMF to a coil. The effective EMF is reduced by the back EMF. The wheel is acting like a coil. It is providing Counter-Gravito-Motive-Force, analogous to Counter-Electro-Motive-Force.
But not being an engineer you probably won't have the slightest idea what I am talking about - so I forgive you. ;-)

There are plenty of engineers on this discussion board Grimer - they've made reference to it at some time or another & I mostly remember who they are - they choose not to promote that for whatever reason - it should mean however that they are better prepared than most when starting this quest which could save time & effort for them - so far, AFAIK, none of them have managed to find a solution to Bessler's or Keenie's wheel - so I can only conclude that being an 'engineer' isn't the prerequisite to being able to solve these mystery's !
You can persist with the concept of CGMF & the metaphor of the gravity wind, if that makes sense to you - and perhaps you are right & another engineer will follow what you are saying & see the insight within it ? - but so far, the aforementioned engineers are still assessing, before wading in in support I guess ?
I guess I'm going to need after all to see experimental evidence of a useful force or condition that allows for the restoring of Pe [after small losses] for the penny to drop.
Math & physics are a way to view the world & make sense of it - they, in the main for the mechanical realm, should come after experimentation to explain the results IMO [but often some sort of fleshed out theory is required first in this field].
Case in point, the air resistance we spoke of before.
The math & physics is woefully inadequate & a coefficient has to be introduced to align the math equations to the physical observations - this is because of the dichotomy between the Newtonian view [transferring momentum & inelastic collisions] & the Bernoulli view [fluid dynamics, non viscosity of fluids], neither adequately nor accurately explaining what Resistance is, for all shapes & fluid velocities - the different coefficients for each shape in a fluid flow are convenient wash-ups introduced to get the line of best fit for the plotted observations.
But perhaps, only an aeronautical engineer would fully appreciate that ?
