Background .. A large clockwork wheel was said to be made by Wagner that he claimed could replicate B's. Merseburg wheel tests i.e. that it could do the same work tests ( lifting boxes of bricks, lifting stampers ) and could obviously be moved / translocated, and could be stopped and then turn and accelerate in either direction .. I know he made an engraving of it [ John Collin's DT ] with its gearing etc but I suspect he never physically tested it with witnesses present to vouch for it which is recorded - someone else might know whether it was actually built and tested, or never got off the drawing board ..Roxaway wrote:
JB you wont get any argument from me that ultimately a real machine demonstration needs to be built showing how the wool could have been pulled over peoples eyes.
In order to build such a machine it first needs to be understood what is physically possible with the technology of those times and real experiments undertaken.
If it turns out that it is possible to make a large clockwork wheel with the power to lift weights and rewind itself when the weights are lowered then that would cast some doubt on the Bessler story.
As you are saying words are not enough it needs to be demonstrated and to begin with I will be attempting simulations to explore that possibility.

Playing devils advocate.
As I remember it Wagner claimed there was no reason that a wheel should have to rotate as fast as B's. and his would do the same work but at a much slower rpm that it could sustain - iow's his was only capable of rotating quite slowly though he could up the power by storing more internal PE .. and this is an important point because W's. wheel would also not have the ridiculously high acceleration rate of a B. runner - this immediately discounts a clockwork wheel besides the fact that it needs constant rewinding ..
Ovyyus ( Bill McMurtry ) from Tasmania was a prominent, experienced, and knowledgeable member here for decades until more recently - he often took the devils advocate position to explore all angles and give balance to arguments - he was of the firm opinion that whatever solution B. had found ( be that real or fraud ) must have been a type of heat engine ( he designed one based on a Stirling Heat Engine that he thought could replicate the work tests but it was not built afaik - of course it needed stored energy / fuel to be replenished but it was to prove a principle ) - another member eccentrically1 was 100% convinced that another viable solution was to use an environmental force citing things like the Atmos clock and of course Drebbel's clock 100 years before Bessler which used diurnal temperature and pressure changes to drive and continually rewind a mechanism - the problem was being able to do any amount of decent work even remotely similar to B's. tests with something the size and width of his runners .. not remotely possible, even today .. I'll accept that an environmental force could still meet the definition of Perpetual Motion in the 1700's etc, at a stretch ..
For many years I also thought an in-situ ambient environmental force was probably the answer to the extra momentum the runners accumulated, and provided the power output to do work and overcome frictions etc ( known technologies ) - and I played around with aerodynamic lift theories and air and fluid pressure forces etc, to no avail ..
These alternative to gravity-only theories by competent members and my own dipping of toes into aerodynamic lift and drag forces theory etc forced me to keep returning to an inconvenient and inescapable contextual fact which I shared at various times - the on steroids acceleration of B's. runners to operating rpm in only 1 to 2 turns ( some said 1 to 1 1/2 turns ) ..
The importance of that inconvenient fact is that any replication method, be that gravity-only, fraudulent, sequestered environmental forces, heat engines, or some other energy source from the in-situ environment, must be able to replicate ( for an equivalent size ) the same acceleration rates ..
And this applies to the gravity-only crowd as well - we can't even get a wheel to go into asymmetric torque mode and gain even the smallest amount of momentum - we can't even get it to get up to 40 rpm in 100 turns, let alone 1 1/2 turns ..
So use whatever method you can think of to replicate B's. wheels tests, or to argue for a fraud based claim - but never forget the very sobering thought that whatever theory invoked must also have the " real " potential and ability to produce the same astoundingly quick acceleration range of 1 to 2 turns ..
** I'd happily accept that Karl was naive dunce and was duped, and that the witnesses were bungling idiots who signed the certificates, and that B. was a fraud, IF another viable method of doing the same work/tests and having the same acceleration from a standing start could be replicated using the technologies of the time and meeting the definition for Perpetual Motion at the time - we could all go on holiday ..
