Sum of torque

I think your creativity as well as your ability to imagine the devices in operation is remarkable. Genius at work I'd say.

Thanks, but all my ideas are bad

I try with this new one, there is a big difference of radius of the left pulley and the right pulley, I try to move down a pipe with air inside. The bigger pulley decrease its diameter of x, and the small pulley increase its diamter of y with y >> x. If there is a torque this could say in the seond image the belt turn alone.

You know, Edison used to say "I didn't fail, I have just found one more way the lightbulb does not work". So, work in progress is not bad only because it is not finished.

Thanks for your positive feedback !

The problem with the spiral is the torque on the pulley.

Maybe here, move to the right 3 objects in the same time, there is a force F to the triangle. The black is fully in water, it don't receive a left force.

The support is turning clockwise at w. The disk don't turn in the lab frame referenceI => the disk is turning counterclockwise in the lab frame reference. I give the force F3 and I give the energy FRwt but I receive the energy 2FRwt if the diameter 'x' of the disk is small.  Like that, this work until the green disk is not at w.

It's possible to prevent the disk to turn: put inside the green disk a gyroscope, like that it's a continous movement.
