3rd working machine you gandmother could make _2nd Law crushed

I have nothing against this explanation except that the work is done by the gravity - by the weight, which is always pushing down. He utilizes this in his patent to increase the dispacement on one branch and decrease it on another branch.
Gravity of the weight is doing the real work. Or I may be too stupid to understand the reasoning...

Work can be exchanged by increasing or decreasing gravitational potential energy.  In order for a float to rise, a greater (can be only slightly greater) mass has to fall.  Buoyancy schemes are therefore no better than rocks.  Each is passive and does not act as a source of energy:  Lift net mass gain GPE, lower net mass lose GPE.

As the weight increases as does the necessary strength of the mechanism.

Do you mean stresses on the mechanism?
This can be taken care of by using stronger elements using dormulas from the strength of materials/

But from the gravitational point of view the whole mechanism is in equilibrium.
However, the work is done within the sealed chambers, within the system which is in equilibrium. The mass is falling,
without changing the balance.

Im talking about the mechanism that you think the french patent works by which is none existent. Go study the patent and form a better question around the working premise.

Most likely the chamber of the piston moving inward is connected to the chamber of the piston moving outward
in another branch, so there is no air compression involved - it simply moves back and forth not creating resistance.
As I said, this device works strictly on displacement.

And as i will say again the only thing that buoyancy has to do with displacement is the water which an object displaces. that objects ability to become more buoyant is entirely dependent on the compression of its volumes. Yes your  right, buoyancy is dependent on displacement.

And to be more specific because I think you are a little dense, a mechanism linking two sides of this device would incur 1. Mechanical resistance when its shifts 2. Hydrodynamic resistance as the unit revolves

Didn't mean to call you dense just been drinking a little lol.
