The fully solid state design brings back memories of Art's Parts, Art
Bell's material reported to be from a crashed flying saucer. Dejas
vous all over again! Gad I dislike getting senile. Here is an old
vortex post of mine:

Since Art's parts have been raised as an issue related to my
suggestion of using a large cavity shielded from the ZPF in a
oscillating manner to achieve inertial thrust, it seems appropriate
to discuss the parts some.
According to <http://anw.com/aliens/ArtsParts.htm> the layered
material taken from the Roswell crash site consisted of magnesium
layers of 20 microns separated by extremely pure bismuth layers of
3-4 microns. This makes for a vry interesting material for excluding
the ZPF from a cavity, in that Bi is superconducting and Mg is not.
The Mg may simply provide a lightweight structure to support the thin
layers of bismuth.
Of further interest is the notation on the above URL of the ability
of bismuth to expand up to 400 percent. Also possibly related is the
fact that Bi has a compartively high superconducing Tk of 6.17 - 2.6
K in thin layer, 3.9 K or more under pressure. In bulk form Bi is
not superconducting unless under pressure of at least 28 kbar.
It is thus possible that the Bismuth can provide exactly the kind of
variable shielding required for generting inertial thrust, i.e. can
act as a fast ZPF window, as noted earlier in this thread. It can
possibly do this in two ways. First, by applying negative pressure,
i.e. sufficiently expanding the bismuth layer, its superconducting
property might be reduced or eliminated. This does not seem to be a
such a good thing in that regaining superconductivity would take both
time and energy. However, if the bismuth can be stretched somewhat
without losing supercondutivity, then a variable frequency ZPF
exclusion band is created. This would only be of use if the
materials (i.e. the electrons in the materials) to be used in the
inertial drive were sensitive to ZPF frequency.
What is surprsing to me, assuming that the purpose of the material is
to shield selected freqencies of the ZPF from a large cavity device,
is the seemingly comparatively long wavelength of the excluded
energy. Assuming 3.5 micron layer of Bi, this would exclude a
roughly 7 micron wavelength, i.e 7x10^-8 meters. This corresponds to
an energy E = h*c/lambda ~= 18 eV.

This provides a clue to an entirely different method. Instead of
changing the Cavity depth, the superconducting property of the
Casimir cavity surface is eliminated entirely, and very quickly, thus
eliminating the cavity completely. The problem in this case then is
the energy required to recycle.
