Rough idea for gravity powered perpetual motion device

[Nabo00o]

Thanks for the suggestion... I am going to rethink my designs and try to make them better.

The problem that everyone will face when they want to create a selfrunning gravitymachine is that the energy that comes from gravity allways be less than the energy needed to overcome it, because of friction. If you wan't to make it work you'll have to find a way to overcome the gravitational resistance, normally people try to do this by using centripetal forces ( the same kind you get when when the clothes in your  washing machine gets pulled away from the center).
If you in some way manage to use that force to pull up those marbels you can in fact create a selfrunning gravity machine. It isn't easy though

Naboo, you just give the definition of centrifugal forces, not centripetal forces. A centripetal force leads an element towards the centre, from outside ..

Oh sorry, I must have mistaken the two...
Btw, is there some kind of motion that will create a centripetal force? Like an anti-rotation like movment (whatever that is....)

G'day all,

@ Naboo,

You are correct. In physics there is no such thing as centrifugal force. What we call centrifugal force is the equal and opposite reaction to centripetal force.

Okey, so that's the correct term on that effect. But do you know if there is some visable effect of the centripetal force then, and not its opposite.
Oh, mabye thats the force that keeps the pendulum or unbalanced wheel from moving, the axis that it rotates on....
