Yes, I give an energy to rotate the disk and I counted all I lost and all I win during the time the spring is rolling up on the helix. I lost the work from 2 torques on the disk and I win the length of the spring. But maybe I made a mistake on my calculations.
I don't understand. Have you understood the device ? If yes, and like you know physics tell me where is my mistake if you find it.
No, I post my ideas and try to prove with calculations it is possible to create/destroy the energy.
