My theoretical device works and I try to prove it works with gravity and mass too. For that, I use an external planet, very far from my device and the planet move in translation when my device is deformed.

Case 1/ the energy is conserved:

Case 2/ the energy is conserved, I move out the white parts from the bottom and I move the same white parts between the rectangles:

Case 3/ The energy is not conserved, I move out the white parts and I move in water:

Have you allowed for the work done by or against gravity when the planet moves with respect to the device?

I have. I compared 3 cases. The last case can't keep constant the sum of energy is the two first keep constant the sum of energy.

How have you calculated the gravitational energy change?
