Nonsense. That is another Straw Man. I use "/\" as a generic term. At the large scale > 300 Megaparsecs it is Einstein's cosmological constant - a coarse grained quantity in the FRW metric.
At smaller scales it is simply a local scalar contribution to the zero point stress-energy tensor. For example if you use the Bryce Dewitt formula beloved by Hal,
tuv(Casimir) ~ (pi^2/720)(hcbar/a^4)Matrix
Here then BY DEFINITION
(pi^2/720)(hcbar/a^4) = (c^4/8piG)/\(Casimir) = (Superstring Tension)/
/\(Casimir) = (8piG/c^4)(pi^2/720)(hcbar/a^4)
Where [/\] = 1/Area
If you can't do the math, then be silent. This all has to do with the math. Your understanding based on "words" is not enough for these technical details.
"No other Physicist is trying to accomplish such a feat I'm told. No wonder I don't have a clue as to what you're saying but yet Hal's et al papers are clear, everything is explained.......Robert C"
That's not why you have not a clue I am afraid. ;-)

Of course it is not there in Hal's paper.
1. He does not understand it yet as I just explained.
2. It's tiny and unimportant in those experiments so OK to neglect it there.

"Hal just sent me his paper on condensed charges see attached. There is no anti-gravity between the plates or with condensed charges. It's simply a "mode" or "vacuum pressure" effect...Rmc"
Hal's model is completely wrong. It's based on his wrong idea that UNIFORM ZERO POINT ENERGY DENSITY is WEIGHTLESS i.e. no direct gravity influence.
Hal has a uniform positive pressure ZPF /\ ~ (mc/h)^2 filling all of space OUTSIDE the shells of charge with /\ = 0 inside.
This is IMPOSSIBLE if you read Lenny Susskind's Cosmic Landscape and actually understand what you are reading.
The pressure in that case is enormous, it is
(c^4/8piG)/\ = 10^19Gev/(10^-33 cm)(10^22)cm^-2
with /\ < 0.
We could not exist in such a universe! It is a DEAD REGION of the COSMIC LANDSCAPE.

Shoulders has yes.

"Well, by the definition you cited then it would be negative pressure that holds the condensed charges together or the force of the vacuum pressure not gravity."
No, you are confused, but it is easy to get confused on this issue. Indeed I first made this mistake, which I am correcting in the revised version of Super Cosmos I am still reworking.
Example 1: Ordinary Casimir Plate effect
The virtual photon pressure is negative in the longitudinal direction perpendicular to the plates. There this negative pressure electrically SUCKS the plates together causing the observed attractive force. You can picture it as excluded modes in between the plates. At the SAME TIME that same negative virtual photon pressure causes a DARK ENERGY anti-gravity repulsion between those plates BUT IT IS VERY SMALL and not noticeable. In principle it might be measurable as a small correction to the QED Casimir force.
Example 2: Thin spherical shell cavity of charge Q at radius r of total mass M, angular momentum J. ZPF pressure outside the shell is assumed to be negligible relative to the ZPF pressure inside the shell.
If the ZPF pressure inside the shell were negative it would add to the Coulomb repulsion and the shell explodes like a huge bomb. If the ZPF pressure inside the shell were positive it will gravitationally attract and hold the shell of charge together. Of course the electrical effect of this same positive pressure repels like the charge itself (that is the hc/r term), but the whole idea is that the gravity attraction induced by the interior ZPF compensates for that to find a stable configuration on the energy "landscape".
