Space Station Shield

gravity. She has created a machines which resembles a turntable that is
said to be capable of keeping a bowling ball suspended above it. She
claims that computer testing for the final device won't be finished for
about 2 years. It is claimed that this device would be able to create a
shield around a space station and protect in from collisions. "...the
device is neither a gravity machine or gravitational shield" said
Johnathan Campbell a NASA scientist. He went on to say it produces a
gravity like field that can either attract or repulse.

Would this be Li of the Huntsville team researching the Podkletnov
claims?
Funny that we heard it first hear and not from Nasa.

Hi,
First let me be the first to admit I don't know much about this field of
science!
Eugene Podkletnov claimed he used a rotating high Tc superconducting
disk, exposed to high frequency magnetic fields. I am not sure of all of
the mechanics of her machine. I do know supposedly the machine is
capable of generating a one foot column from it through the atmosphere
in which gravity would be modified. I believe Li was one of 2 psysicists
who wrote papers BEFORE Podkletnov but this wasn't in the Popular
Mechanics article.
You asked if she was Li of the Huntsville team researching the
Podkletnov claims, I really don't know.
As for Popular Mechanics carrying this story, I notice that lately they
seem to be getting more science oriented, I also notice the amount of
pages in Popular Mechanics is now a lot more than the amount of pages in
Popular Science. Of course Scientific American goes much more into
depth.
Here are the papers in which I believe Li was involved unless there is
another Li working in the same field, there may be more I don't know
about:
"Gravitational effects on the magnetic attenuation of superconductors."
N. Li and D. G. Torr, Physical Review B v. 46 n. 9 (1 Sept 1992)
5489-5495.
Abstract: It is found that when gravitational effects are taken into
account, the two historical independent traditional hallmarks of ideal
superconductors --perfect conductivity (sigma) and perfect diamagnetism
characterized by zero permeability (mu) -- are actually related to each
other in terms of a theoretical sigma-mu model developed in this paper.
Our result suggests a possible importance of gravitational effects in
understanding superconductivity.
"The Gyromagnetically Produced Gravitomagnetic Field in
Superconductors."
N. Li and D. G. Torr, Bull. Am. Phys. Sco., v. 37, n. 2, p 948, 1992
(presentation G8 9 at an APS meeting).
Abstract: We report the possible importance of gravitational effects
in understanding the Meissner effect and the London moment. We propose
that the observed London moment or residual magnetic field B inside a
superconductor must be balanced by a magnetically produced
gravitomagnetic field Bg such that Bg = -(e/me)B. This gravitomagnetic
field arises from the interaction energy - M . Bw of the Bohr magneton M
of the vortical motion of the lattice ions with the magnetic field Bw
produced by the gradient of the superconducting condensate coherent
wavefunction. We also show that the magnetic attenuation coefficient
Beta for a superconductor is given by m2 mugo mt/q2 mu me and is mu0 mt
/ mu me times larger than the free space value of Beta = m2 mugo /q2 mu0
~ 10-43. Of particular importance, the near-zero permeability mu for an
ideal superconductor results in a significant gyromagnetically produced
gravitomagnetic field Bg ~ -(Beta e / me)B0. In the case of a free
moving superconductor, the Bg field will manifest as induced angular
motion with the
rotational (precessional) angular velocity equal to Omegag = - (Beta e /
2 me)B0, where B0 is the applied magnetic field.
"The Gravitoelectrodynamics of Superconductors: A Theoretical Basis
for a Principle of Electrically Induced
Gravitation."
D.G. Torr and Ning Li, Bull. Am. Phys. Sco., v. 37, n. 2, p 948,
1992 (presentation G8 10 at the same meeting).
Abstract: We solve a time dependent coupled system of Maxwell's
equations and their gravitational counterparts which represent the field
equations of general relativity in the low-velocity, weak-field limit
and an associated generalized set of coupled Ginsburg-Landau equations
to determine the electric and
gravitational fields induced in a half-infinite superconductor in the
presence of time dependent London guage magnetic and gravitomagnetic
vector potentials. The results indicate that a small rate of change of
the London guage vector potential could generate an internal
gravitational field by induction. Experimental confirmation of the
results would further validate general relativity and establish the
existence of the gravitational analogs of the electric and magnetic
fields, and provide a basis for the electrical generation of
gravitational fields in the laboratory.
"Gravitoelectric - Electric Coupling Via Superconductivity."
D.G. Torr and Ning Li, Foundations of Physics Letters v. 6, n. 4,
(1993) 371.
Abstract: Recently we demonstrated theoretically that the carriers
of quantized angular momentum in superconductors are not the Couper
pairs but the lattice ions, which must execute coherent localized motion
consistent with the phenomenon of superconductivity. We demonstrate
here that in the presence of an external magnetic field, the free
superelectron and bound ion currents largely cancel providing a
self-consistent microscopic and macroscopic interpretation of near-zero
magnetic permeability inside superconductors. The neutral mass
currents, however, do not cancel, because of the monopolar gravitational
charge. It is shown that the coherent alignment of lattice ion spins
will generate a detectable gravitomagnetic field, and in the presence of
a time-dependent applied magnetic vector potential field, a detectable
gravitoelectric field.

This rumor has shown up on a number of newsgroups recently; apparently there
was a recent hyped-up article in ``Popular Mechanics'' (of all places!) on
Ning Li's attempts to replicate the alleged ``Podkletnov effect,'' which is
rapidly becoming even more exaggerated via the usual ``telephone game effect.''
One should certainly take all such claims with about a metric tonne of
NaCl, given that at least one alleged co-author of Podkletnov's paper
repudiated it, saying that he had never even *worked* with Podkletnov,
that no one has been able to replicxate his alleged result, and that
Podkletnov himself withdrew his paper before its scheduled publication...
I think it's generally accepted at this point that the ``Podkletnov effect''
was either the result of a serious experimental error on Podkletnov's part,
an example of ``pathological science'' a la ``cold fusion,'' or a hoax...
