Mathematical Analysis of an Ideal ZED

I really hate to argue with you T.  I respect your knowledge and intellect more than your cohorts. But..   Can you show me a reference to that statement, other than your own?         Please?? You must have a copy ready for cut and paste.

When you place a buoyant object in water, gravity causes it to sink. As it sinks it displaces water, that makes the level of the water in the outer container, or ocean, rise up a little bit. Gravity pulls down on this water. There are NO OTHER FORCES than gravity happening in buoyancy!  When you lighten the displacing object, gravity makes more water flow UNDER it and it is this increased water UNDER the object that makes it rise up to a new equilibrium point. The whole process is gravity-driven, gravity controlled, gravity is the only force involved. Buoyancy is simply gravity, shifting water around.
Now you can play around with gas pressures like in the Cartesian diver, to change the effective volume of the displacer, but make no mistake: it is gravity and the weight of the displaced water (not the mass this time, the weight) that float your boat or your Zed.

Why of course:  Let's discuss that.  Just post a diagram and your math.  Show your energy gain.  Force gain won't cut it.  We need to see you "turn buoyancy on and off at will", and/or gain energy at will.  Are you finally up to the task?

My rule not yours - not your machine... sorry.

Since you have a tiny bit of understanding - I will jump ahead a bit.

P.s. don't tell me if you agree or not - you don't get it - I got that.

When a ZED is sinking - the heads are lower

When the ZED is rising - the heads are higher

RIght, right.

The lower heads result in a concentration of the forces to the middle of the ZED

The higher heads result in a greater distribution of heads.

The result ----the loaded ZED more effectively utilizes the total surfaces

The Sinking ZED uses less surface area

The benefit:

Less pressure needed per pound on the lift.......

Less load to create pressure on the sink........

And the difference between the two...........wait for it - not equal rocks......or Non conservative

RED and I explained this year ago.....

p.s. to save your MATH - if you leave the same load on up and down - it is a rock - or "brick" as you see it.

Not what we do buddy.

Buoyancy Summary
Fb = p*V*g
•p is the density of the displaced fluid
•V is the volume of displaced fluid
•g is the acceleration of gravity
•That is, Fb is equal to the weight of the displaced fluid.

What I said, gravity is the only force involved.

(People are gonna see that "rho" for density and think it's a "p" for pressure, just watch.)

So you can't demonstrate turning buoyancy on and off after all, can you?

Since you have a tiny bit of understanding - I will jump ahead a bit.

So where have you turned buoyancy on or off?  Shifting weights around does not alter the principle of buoyancy.  Let's see you describe something that can be verified where buoyancy is active one moment, and is not active the next.
