Free Energy will change the World - Free Energy will stop Climate Change - Free Energy will give us hope
and we will not surrender until free energy will be enabled all over the world, to power planes, cars, ships and trains.
Free energy will help the poor to become independent of needing expensive fuels.
So all in all Free energy will bring far more peace to the world than any other invention has already brought to the world.

Helmholtz, the guy who came up with the conservation of energy laws did not think that perpetual was impossible either, see below quote, which has been excised by science from his paper "Ueber die Erhaltung der Kraft" (On the conservation of force)

One wonders why.

Hans von Lieven

Force is only an alias for a unrecognised or hidden strain. I realised this years ago from my work on materials testing where what one takes as stress and what one takes as strain is quite arbitrary.

There is a problem with WM2D with the ridgid joints,
So always only use pin joints,
Just use 2 pin joints, if you need to fix 2 things together.

Thanks, Stefan. That seems to fix the problem also with KAS's model. Wonder why is that? Probably the program treats the rigid joints as some kind of active elements.

Take a look at the calculated and displayed velocity and acceleration. There's something very confusing about all this. Someone should explain what's going on. Otherwise it's just a waste of time to model these contraptions. (see attached)

Again the rigid joint problem.
I just fixed this using 2 pin joints.
Then it behaves normal.

Never use RIGID JOINTs in WM2D.

Correct. I saw that. Fixes also KAS's design. Have you noticed, when with rigid joint they seem to wobble slightly during the rendering process. Will have to try with that design I posted 20 or so pages back that we discussed with @mondrasek. Forgot what exact page that was.

The key is that if you have a WM2D model, it should accalerate! Because otherwise you can't built in in real. The accaleration is "the force" you need to have it at least stay at a steady rpm in real life.  (Not to mention to hook up  generator)
