Sjack Abeling Gravity Wheel and the Worlds first Weight Power Plant

When I have the time I will do an power study in your models.

If you could have a look at the list of same models with all possible materials I posted that would be great

This remains unanswered as far as I am concerned.

Thanks

I thought it's already established that wm2d is unfit for models with elastic collisions and with springs. To obtain physically consistent results in such cases palliative measures such as turning on air resistance, adding bumpers etc, have to be taken. Also, the rigid joints must be Measurable and not Optimized.

No that is not established at all, what gives you that idea?

If you look again you will find that all real world settings are active.

All default material matching elasticity used.

So again, not answered.

It's not a matter of whether or not the settings are correct. There are intrinsic problems with the algorithm of the program itself which were demonstrated by several examples, including yours. Whenever springs or elastic collisions are involved additional measures have to be taken, such as turning on air resistance, adding bumpers and who knows what else to obtain a physically meaningful result. In your case to have the model exhibit the behavior known for ideally elastic collision the elasticity number you have to plug in is physically unrealistic, that is, has to be much less than 1. So, in your case, you have to plug in a physically unrealistic value in order to get a physically meaningful result. Same thing with springs -- you have to exclude the machine from working in vacuum in order to have a physically consistent result. That's non-physical and demonstrates the weakness of the program in such cases. I don't think we should continue with these curiosities whose only merit is revealing the weaknesses of wm2d. At this point the sensible path is to deal with your egg-shaped examples where practically there are no elastic collisions essential for the model and there are no springs and other known issues with wm2d. Besides, these are the models applicable to the discussion at hand -- Abeling's patent.

Would it just be better if the design was built and tested? After all, trying to get peretual motion on wm2d is harder than real life because not only do you have to solve the problem, but work around the faults of the program.
