yes,the green and blue ball ramp experiment is just the same as a lever
construction or a pulley construction.
You pull a heavier weight up by pulling double the length,so the energy
stays the same.
Did not work.
Now I see it too.
But look at my new centrifugal force helped wheel in the other first thread
on this board.
It seems to run pretty nice and also shifts the CoG over the axis all the time.
Regards, Stefan.
P.S: Alex, did you already try a few household weights on your wheel ?
So how is it doing ?

Everything is ready, just need the weights, the rim is attached on, only thing, my wheel has been built and is good but if it works it probably wont last that long as the levers will soon snap?
I would think it would last a few months then it would have to be stopped and kept still and have just for show?
Im off to get some car wheel weights and melt them to make weights for my wheel, then the other side of the wheel can be fixed on.
Failing this, then I have something which comes from this (improved) that should be an eye opener, time will tell?

Have you thought of getting weights from your local sporting goods store?

Alex, lead -- as is used in car wheel weights -- is extremely toxic even in low quantities. It causes brain damage among many other things. Breathing fumes from melting lead is an excellent way to get a lot of lead into your body. I hope you know what you are doing. I can't see why you don't just buy some appropriate-sized steel hexagonal nuts at your local hardware store.

[ETA: or as erickdt suggests, weights from a sporting goods store.]
