Viper,
I have also thought of using two forces, namely gravity and magnetic. The first wheels were out of balance at all times, meaning that if the restraining cord was removed, the wheel began to turn. This would seem to me, to count out the use of centrifical force.
The center of gravity thing is a puzzle to me, and since there have been no useful replys to my posts concerning same, it must be a puzzle to many others. I have not decided whether Bessler understood the exact meaning of what he wrote, or if he added the bit about the center of gravity to lend a semblance of the scientific to his description. It would seem the extreme upper limit of the center of gravity would be somewhere below the highest height of the weights.

: 1 Using 2 sets of forces to make a PM wheel?
: I thought of a design using gravity for the turn force,
: but centrifical force to move the weights; both forces
: work totally independently of each other, with their own rules,
: and help/compliment each other...looks great on paper,
: I will build this one!
: 2 On center of gravity-is it possible to keep the center
: of gravity outside a wheel for a full 360||? How high
: can it be-is there a proven limit? I think it can be as high
: as the very top edge of the wheel...another of my
: designs will try this, it should be very 'tipsy' and
: unstable...like balancing a broom on your hand!
: Viper (I wish I had more time to experiment!)
: Note: My first design would seem to NOT work, I would shift
: weights laterally outside the wheel(in 2 places),
: then put them back in
: at a better place (for power, or lift) I think it won't
: work because the center of gravity is VERY low, it never
: goes above the central hub...oh well-I have others to try!
