Hydro Differential pressure exchange over unity system.

So this is confusing.
When you use pressurized air the system will start to act like a pneumatic cylinder.
In that case the cylinder starts to rise on the air pressure in stead of buoyancy.

Air pressure needs to be below atmospheric pressure otherwise you are overruling buoyancy.

Well I think it needs to be understood that any "air chamber" that is under water is affected by the water pressure. So, for example, if you take a soccer ball and try to drive it to the bottom of a swimming pool you will find that is becomes soft. This is because the water pressure has overcome the air pressure inside the ball. A ball that is normally very hard (due to air pressure) on the surface becomes soft (in relation to the surrounding water pressure) as you go deep in the water.

Initializing a Zed system with compressed air is only NEUTRALIZING the outside pressure from the water. It is not driving anything to move like in a pneumatic or hydraulic cylinder. How could it? The system is open on top.

Ever see a pneumatic or hydraulic system work with an open end (leak)?

Buoyancy.

Check it out.

Great post, BTW.

My issue is that as the pod rises, water would need to be added to the pod container to keep the system in balance. This seems to be an issue in both cases, mainly air (Fig 15 to Fig 18) or mainly water.

I'm with you on this. That is exactly why I would like to *see* a model out of acrylic. I cannot visualize this part of the cycle so far.

I've gotta run now. Have a 4.5 year old who has been left in my care for an hour or two.

Larry, thanks for giving this the mental horsepower I believe it deserves.

M., Back at you.

@All, new Travis drawing with much more detail, let's start trying to understand.
