Thanks Eric, I took a quick look. Looks useful I will get back to it.
You are getting closer to my qualitative position already in my two
books from 2002. Thank GOD(D) no mention of PV anymore! ;-)

I am still skeptical whether we need branes or not. Maybe.

I think all we need are ANYONS IN 2D films with a kind of Josephson
Effect to control the local inflation vacuum coherence field - it's
still with us of course because curved spacetime emerges from it in my
theory. The reality of the alleged alien machines, that you and I agree
about at least as a working hypothesis, means that the "Skinwalkers" or
whoever have some "soft" "Aikido" way of manipulating the local
geometrodynamic fields in the ship's fuselage perhaps directly with
their minds the way Uri Geller bends metal? This, after all is what Ron,
Kit, Hal et-al are interested in ultimately of course for reasons of
Homeland Security.

The basic gravity field consists of the four tetrad 1-form fields

e^a = 1^a + Lp[(dTheta^a)(Phi^a) - (Theta^a)(dPhi)^a]

a = 0,1,2,3

The second term on RHS is the curved tetrad compensating gauge potential
from locally gauging the translation group and also hiding the globally
flat translational symmetries in the vacuum. This is basically a SPIN 1
theory with a SPIN 2 COMPOSITE from pairing in

ds^2 = e^a(Minkowski)abe^b = guvdx^udx^v = Einstein's differential local
invariant

e^a = e^audx^u

See http://arxiv.org/pdf/gr-qc/0602022

d is Cartan exterior derivative, i.e. gradient on the EIGHT 0-form
Goldstone phases Theta^a & Phi^a from hidden locally gauged symmetries
in the vacuum giving rise to emergent geometrodynamic structures, e.g.
curved space-time itself and perhaps Calabi-Yau -- "More is different"
(P.W. Anderson). e^a is dimensionless hence the Lp factor.

When all Goldstone phases vanish all we have is the unstable
pre-inflation false globally flat vacuum out of which the Level 1
Tegmark "bubbles" "nucleate" in eternal inflation populating all the
nooks and crannies of Lenny Susskind's "Cosmic Landscape" that in FRW
limit has "height /\" with about 10^500 valleys from the extra 6
dimensions of the Calabi-Yau fiber space that seems to fit Gennady
Shipov's 10D torsion manifold rather naturally. However, I seem to get a
mass gap Meissner effect for the torsion quanta. Our universe in Lenny's
megaverse is inside an expanding Hubble horizon on one of an infinity of
bubbles in the false vacuum's hyperspace. "My Father's House has many
mansions." BTW see the Hindu Vedas about ancient "Wars in Space" in
addition to new alleged info from the Dead Sea Scrolls.

When we also locally gauge the Lorentz group as well as the translation
group we get 6 extra independent torsion field 1-form compensating gauge
potentials

&W^a^b = - &W^b^a ~ Lp[(dTheta^a)(Phi^b) - (Theta^a)(dPhi^b) -
(dTheta^b)(Phi^a) + (Theta^b)(dPhi^a)]

Note &W^a^a = 0

This &W^a^b is an additional piece to the SIX ZERO TORSION SPIN
CONNECTION 1-forms W^a^b

W'^a^b = W^a^b(1915 GR) + &W^a^b

i.e.

D = d + W^ab/\

D' = D + &W^av/\

De^a = 0

D'e^a =/= 0 = Shipov type of torsion 2-form (Kiehn has others I think)

R^a^b = DW^a^b = curvature 2-form without torsion

R'^a^b = D'W'^a^b = curvature 2-form with Shipov-type torsion.

FAST FORWARD
Control of dark energy for warp drive is via PHASE LOCK of ANYON
CONDENSATE to VACUUM CONDENSATE in thin high Tc films nano-engineered
into the the fuselages of the "alien craft" from universes next door in
the megaverse.

I am not disputing that. I have not seen what you are doing in detail
since the USAF teleportation report that I liked except for your
promoting PV as a viable alternative to a frontal assault on metric
engineering with GR (extended to torsion I think). I think Hal should
keep PV buried - it is simply too incomplete and it violates the LOCAL
equivalence principle and tensor covariance. We can debate that later.
The deepest way into the equivalence is the local gauging of all
universal continuous space-time symmetries of ALL physical dynamical
actions. We also have additional choice of "hiding the symmetry" (Sidney
Coleman) in the physical vacuum. Note that R. Kiehn has a paper
http://arxiv.org/pdf/gr-qc/0602118 on using Cartan forms for vacuum
structure similar in spirit from my approach though his math is much
deeper than mine. He has been doing this kind of math for many decades.
I am still learning it.


Although, the attached third STAIF paper (and attached PP slides in PDF
format) that I published and presented addresses being able to do warp
drive from a D-brane perspective where positive energy and negative
pressure are required to establish an FTL velocity boost. The lead
author of the paper is a NASA-JSC robotics engineer working on his Ph.D.
in GR physics at Rice Univ. under the supervision of one of Rindler's
former grad students. He previously published an earlier version of
this paper as a single author in GRG.

Thanks will look at it. :-)

CORRECTED DRAFT 3! (got Casimir-Gravity ratio wrong UPSIDE DOWN -
mechanical algebraic error)

....

Eric keeps talking about "negative energy" that is too incomplete.

The dominant 00 GR source term is (in isotropic case for now, ignore
plate effects, ignore rotation)

(energy density)(1 + 3w)

w = pressure/(energy density)

When w -1/3, then you do need negative energy density to get repulsive
anti-gravity, which is Eric's point I suppose.

However, when w -1/3, you need positive energy density to get
repulsive anti-gravity.

Now for zero point energy of all types from Lorentz covariance and
equivalence principle minimal coupling, i.e. the generators of T4 are
locally gauged inducing the curvature field.

w = -1 for isotropic distribution

For Casimir plates oriented in 1-2 plane, De Witt's result cited by
Puthoff for only the EM ZPF is

t00 ~ -1, t11 ~ +1, t22 ~ + 1, t33 ~ -3

The energy density between the plates is negative from excluded modes
perpendicular to the plates.
The longitudinal pressure is also negative and is 3x the energy density.

OK, but what Eric Davis and Hal Puthoff & Co do not seem to understand,
or at least, I have not seen them make this key point is:

The electro-mechanical effect of the negative pressure term t33 is
attractive, i.e. a quantum electro-mechanical SUCTION between the
plates. However, the direct ZPF induced gravity effect of negative
pressure is REPULSIVE in that direction, though usually it is much
smaller than the electromechanical attraction.

Just the opposite of course for t11 = t22 positive pressure, i.e.
squeeze - stretch.

The Casimir quantum electro-mechanical term is

Casimir Force ~ x(hc/L^4)A

x ~ pi^2/720 (from memory)

A = area of plates, L is separation of plates along 3-axis

Casimir inward acceleration of the plates IF not constrained

a_c33 ~ - x(hc/L^4)A/M = xc^2(h/Mc)(A/L^4)

M is mass of a plate

The gravity ZPF term is from

V(ZPF)33 = -c^2/\33L^2

a_g33 = -dV33/dL = +2c^2/\33L

/\ positive is repulsion, /\ negative is attraction

In this anisotropic case the effective longitudinal w is +3

V is negative making the effective /\33 positive

/\33 = -(t00 + t33)(8piG/c^4) = x(8piG/c^4)(hc/L^4) = 8pix(Lp^2/L^4)

a_g33 = 16pic^2xLp^2/L^3

a_g33/a_c33 ~ [16pic^2xLp^2/L^3]/[xc^2(h/Mc)(A/L^4)] =
[16piLp^2/L^3]/[(h/Mc)(A/L^4)]

= [16piLp^2]/[(h/Mc)(A/L)] = [16piLp^2L]/[A(h/Mc)] = 16pi (Lp^2/A)(L/(h/Mc)

= [(# Bekenstein-Hawking BITS)(Plate Separation/Compton Wavelength of
Plate)]^-1 1

i see no ailens anywhere
