continue from the above model, this time only very slightly reduce the number of weights/balls, slim down the length of the wheel.

only minor modification on the curve and displacement of weights on left/right wheel (to squeeze out as tiny torque force as possible. judging from this wheel, maybe can still design further to push out some more torque force gain)

found my old wheel modeling (think it's last year when i model this wheel, with failed simulation, obviously) when sorting through my file directory. Showcase this wheel now before it went dormant again.

That wheel is clearly bottom heavy. Look at where the CG is and where the most balls are.
A self rotating wheel will need to be top heavy or side heavy.
It has a great look and great mechanics but.......

Can some one explain CG to me a bit, for example,

I have a 1 meter stick, at each end is a 50cm wheel with a 1kg weight inside (alternator attached to the inner of the wheel so when the wheel spins the alternator turns).
as the weight will always be at the bottom of the wheel, that would throw the CG down the 1m stick by 25cm.
would that 25cm of off CG be enough to loose any potential power gains?

Second question, regarding the picture below (roughly drawn on paint (im not pc world guy)),
with the electro magnets only kicking in when they are needed, would that cause ou or not?

im sure both these have been tried and tested before, they are just something that have been in my mind for a while.

sorry for not finding the correct places, I just wanted an active forum with allot of expertise looking at it daily.
