As I said

"The title of the topic is What's wrong with this.
The subject, is the conversation we are having, not the floating device."

As I said before

"The title of the topic is What's wrong with this.
The subject is broadly speaking, how to improve the OU forum through self
improvement.

This is not an attack upon you or any other particular person.
However, I will say that for you to think the topic is about you or for some other to think so
does seem rather narcissistic ?

As is stated previously I respect both your knowledge and experience.

Quote MarkE: If it is gas tight, then by definition gas cannot enter or leave.
Answer-incorrect.

Then you have a different definition of gas tight than I do.

Quote

Quote MarkE: but it sounds like you want to change the volume of your submerisble.
Answer correct.

Quote MarkE: Once what is eliminated?
The question was very clear-->What GAS can return most of it's energy to the source once it is eliminated.

Again once what is eliminated?  Which noun does the pronoun "it" refer to that is eliminated:  the gas, energy added to the gas by the source, energy in the gas above and beyond that added by the source, or the energy source?

Quote MarkE: it all depends on whether the mass falls through a fluid or a vacuum.
Quote TinMan:but remains in the vessle to be used once again once the vessle has reached the ocean floor.

You are changing the order of the questions.  The question as stated was: 

Quote

QuoteWhat is the total energy of a 500kg mass falling 3.2 kilometer's?

To which the answer was:

Quote

QuoteMarkE: it all depends on whether the mass falls through a fluid or a vacuum.

Quote MarkE: it all depends on whether the mass falls through a fluid or a vacuum.
So 500kg's of grass is heavier than 500kg's of bricks

How could you possibly infer such a thing from the dependency on what if any surrounding fluid mass has to be displaced?

Quote

Regardless of being in a vacume or in a fluid,the continual force would be 500kg's over a distance of 3.2 kilometers.

Tinman, the GPE change required to lift a mass in air is:  Ge*h*m*(1-p_air/p_mass).  In water it is: Ge*h*m*(1-p_water/p_mass).  Do you see how when the density of the mass is less than the density of water that the sign reverses and work is required to submerge the mass, and is released allowing the mass to rise.  How much work do you think that it takes to sink or raise 500kg of water in a column of water?

Quote

This one would not be a waste of $20 000. This is one that would work.

2000 years of human experience with buoyancy says that you are most certainly mistaken.

Yes you keep saying that even though your statement is inconsistent with the content of your OP:

@ MarkE

Where was I ?

Ah yes.

"Consider now, that this "style of communication method" is something that a person may have endured for some course
of time which is not just a day, but perhaps for a week, or months or even a year." quote from floor.

More than a few people have had nervous break downs, gone into the loony bin, or commited suicide from attacks through
social media.  Some one very dear to me lost his boy friend.  This was by his suicide.  And yes is was spurred by
an orchistrated attack via social media.  An attack that had gone on for only a few weeks.  A teenager.

Doing such a thing to another human being, holds no appeal to me.
