3rd working machine you gandmother could make _2nd Law crushed

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.

That is a fantasy if we are still talking about the french patent but fine, sounds like a lot of mechanical resistance.

@David: You should check out Wayne Travis's devices and claims. They put Kwok's claims and device to shame, and Travis actually has received a US patent recently.

Try not to laugh too hard.... If you look on YT you can find a couple of video "demonstrations" of a couple of Travis's devices.

You have made my day Mr. Koala.

And as I said, the device in the French patent is just a variant of one that is fully analyzed on Simanek's page. How the patent ever was granted is just an illustration of the flaws in the French patent system, which are not unique to France.

Look at the diagram below.

The piston weights are pushing air from one side to the other, working by weight, moving displacement from one side to the other just as you said. Put the weights on lever arms... no difference, just more sources of drag.

And of course it will not work.

In the patent weight is moving the piston outward/inward, not the air.Air volume between two chambers doesn't change,
it just flows between them just to maintain a free movement of the pistons.Semanek's machine is not described
completely, it misses important function of the weights.

What kind of resistance you are talking about - hydraulic, pistons within the cylinders, or something else?
In any case, the weight can be chosen large enough to overcome it, IMHO.

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