Increase the potential energy without any energy

[activ25]

I take the device with the whte disk fixed (disk or another shape).

1/ the energy from the walls is constant
2/ the potential energy at start is constant
3/ the potential energy at final is constant
4/ the potential energy of any layer 1, 2, anywhere I take it is constant
5/ the pressure of the layer 1 is not the same than the layer 2, I can choose any layer I want, so the sum of energy cannot be constant.

Hey ! so easy now !

All the energies are constant except the energy I recover from the line 1 (to move out the line of spheres, not the potential energy of the springs) and the energy to move in the line 2. It is the energy from pressure.

The energy from the walls don't depend of the lines 1 and 2 I choose, it is a constant.
The white object is fixed to the ground, so no energy from it.
The potential energy at start and at final don't depend of the lines 1 and 2 I choose.
The potential energy of the line 1 and 2 are the same (the energy stored in the springs).
