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.

At ironhumper (lol) nice model

wm2d and springs are still a mystery to me but I will figure it out eventually.

Just a reminder "The weight of the bodies together with ... (intentionally omitted) and the rotational velocity determine the amount of energy that can be generated."

Could the blank be: the flexibility of the springs???

I hope I can ask Mondrasek some questions about the use of springs in wm2d when needed....

Fire away.  But I must warn you, they are one of the most difficult items to use correctly as far as I have seen.  And they kill even the fastest CPUs.

Also, I am by no means a WM2D expert.  I can only comment on what I've already experienced and theorize based on some experience with other simulation programs.  But I'm happy to give my opinion and will try to note it as such when it is not actually "fact".

@AquariuZ:
I like you spring ideas. Right now I can't choose between springs hooking to weight or to the central shaft. In a totally symmetrical system, the effect woudl eb about the same I think.
Nice about the springs, if those would be the key, is that they'd make it a self-starter most likely.
I start to wonder about the ramp layouts then though. Forces might often be inward.

If I take Abeling´s hints literally, it would be two opposite dumbbells connected to each other via their respective shafts... Egg and ramps as in Fig 2, 3,4.

No working model I can present yet...

ONE IS PUSHING ONE IS PULLING

Release is near 11 o clock (eject) where it is caught in the ramp and where according to him the extra energy comes from.

Definite self-starter...
