Hi Vector V,
I'm toying with an idea where twirling weights go up faster on one side and slow down on the other - looking at it strictly by static weight the wheel is always heavier on one side, but dynamically??? Now I think it may rotate in reverse of what I was originally thinking! Definitely need to calculate a little more. It seems you've come across such an "odd" beast?

: : I was playing with increasing velocities by spiraling weights in a coil to see if I could derive more energy than from freefall. I put a BB in a tightly coiled copper tube , arranged vertically. It had about 20 feet of travel. When it came out the bottom after all that swirling about, it was barely moving!
: How big was the tube? friction+air resistance took a LOT
: off the speed, I'm sure..
: : BUT, it took a LONG TIME to get to the bottom!!!!
: : I propose that if you can slow the descending side you can have more weight than the ascending side.
: I have a design that may do the reverse;weights go up
: faster on their own rising, giving more time on the fall side.
: Oddly, in other designs, delaying the upside weights helps!!
: There's only 2 things you can do-
: move the weights or mess with time.
: : Now how can we do that?
: Time and sudden weight 'jumps' are what makes these wheels
: work...all that matters is what the wheel feels...BE the wheel.
: Someone here mentioned a PM toy made by his father(?) when he
: was 10 or so...the picture showed coils on one side, a wheel
: on the other. I was wondering-a ball free-falling has
: a certain speed after 1 foot;can this speed be increased by
: spiraling the ball (more time to build speed?) I personally
: doubt it; too easy...
