Recover energy from gravity

[rc4]

Step1/ Accelerate and recover energy from red tube
Step2/ Decelerate and recover energy from acceleration of step 1
Repeat

This suppose it's possible to recover 100% of energy from acceleration, it's possible in theory, in practise this increase temperature and temperature is energy, so the system increase its own energy. The only energy lost is the blank part inside container, but it's a very low energy compared to red tube.

If the velocity to introduce green tube is high, the axis have a force F that cancel themself on one turn but not in each time. In top view, the green tube is fixed, move only in front view. The force F move the object alone. GREEN TUBE HAS NO MASS.

a new test with Multisim (first image) and LTSpice (second). With LTSpice I added a RL for transformer.

For the message # 76, I tested with Algodoo, it's ok the disk move alone. I give you the file for test. You can put all velocity at 0 except rotationnal speed. play, you'll see the disk move alone

The disk don't accelerate, it's ok, because force cancel themself in a turn.

I tested again with Algodoo and the CG move. You can put velocity at 0 for all the scene except rotationnal velocity and play. The velocity of CG is not very high because force from pressure cancel themself on one turn but it move. If you test with ice, you'll see the CG don't move with same scene.

Even CG move when object is inside liquid, the CG is compute with linear law. The law of force of pressure has a cosine function in it.
