Bob each way ;7) Yes, the vast majority of concepts use torque from overbalance i.e. rotation, either directly in the case of a physical ramp like this simplified sim, or indirectly to facilitate a lift like the London Gent's Wheel imaginative use of rope pulls and SB's etc.

That's a very good question, of a technical nature lol. My experience with real world builds and sims is that weights tend to take the path of least resistance (like water). By that I mean how can a Driver weight deploy fully outwards near 3 o'cl on a shallow trajectory (losing little GPE), while at the same time thru it's connections to others lift the more vertical orientated forward Load weights progressively closer to the inner radius thus gaining greater GPE than lost by that Driver ? Vertical physically overrides Horizontal. This is a direct factor of ability to lose GPE. The weight able to lose more GPE than gained by another is 'Applied Leverage In Action', imo. It's non-negotiable Law of Levers.
And why I raised a few posts back the discrepancy of the rope patterns between the CCW 49ner and the CW 51er. To me they both look like non-coincidental conceptual ideas of an idealized situation to achieve sustained self-movement, using weights, SB's and ropes and pulleys.
Given that these appeared as published engravings soon after B's. death, and bare some resemblance to Wolff's comments about expandable arms etc, then I think Oystein's hypothesis is astute and right on the money. Or at least high probability of being so.

That some men, perhaps inner circle, got together and attempted to decipher B's. published books, combined with their societal learning, and come up with what they thought might be his mechanics. However, this concept and others of a similar ilk have been around for centuries, so I think it was unsuccessful, else we'd have them on every street corner and in every home 3 centuries later. And if in private use (tilt of the hat to conspiracy theorists) they'd be expunged from the historical record. So we can safely assume imo that these can not and do not work as intended, and are not potential runners in this configuration. The ol' Good Try, But No Cigar !
I would agree that logic dictates the act of rotation must be at least a trigger to some other actions, in the final analysis. Else we could do away with a rotating wheel environment and just have a reciprocating environment, like a see-saw analogy.
