When cooled to extremely low temperatures, electromagnets demonstrate an unusual behavior: For the first few nanoseconds after electricity is applied to them, they vibrate. David Goodwin, a program manager at the U.S. Department of Energy's Office of High Energy and Nuclear Physics, proposes that if this vibration can be contained in one direction, it could provide enough of a jolt to send spacecraft farther and faster into space than any other propulsion method in development.
Is a time varying gravitomagnetic field generated in the Tampere disk due to the horizontal time varying magnetic field used to rotate the disk, and does this result in a time varying gravitoelectric field in the disk, and possibly also in the space surrounding the disk, and could this result in exclusion of the earth's primary background gravitoelectric field as claimed by Henry Wallace? In addition, questions remain as to whether the gravitomagnetic field (from the Maxwell-like gravity equations) is of a large enough magnitude to produce the effects reported by Podkletnov and Wallace.

discusses some interesting "facts". If there are people who are more familiar with Maxwell's equations than me (not a hard feat, actually), perhaps they can chime in with input on the following:
In the battery, the Poynting vector is outward, indicating
the direction of energy flow. ~Note the sensitivity of this
result to the sense of the current through the battery.! In the
vicinity of the conducting wires and next to the positive terminal
of the battery, S is parallel to the wire. Perhaps surprisingly,
S is directed from the battery on both sides of the
battery. Along the resistor R, the change of direction of E
outside the resistor causes S to change as well, gradually
turning from parallel to perpendicular to the resistor axis
~and entering it!, at its middle point ~zero surface charge!.

This
account obviously does not explain much about the circuit.
Indeed, in the Feynman lectures we read:4
‘‘We ask what happens in a piece of resistance
wire when it is carrying a current. Since the wire
has resistance, there is an electric field along it,
driving the current. Because there is a potential
drop along the wire, there is also an electric field
just outside the wire, parallel to the surface ~Fig.
27-5!. There is, in addition, a magnetic field
which goes around the wire because of the current.
The E and B are at right angles; therefore
there is a Poynting vector directed radially inward,
as shown in the figure. There is a flow of
energy into the wire all around. It is of course,
equal to the energy being lost in the wire in the
form of heat. So our ‘‘crazy’’ theory says that the
electrons are getting their energy to generate heat
because of the energy flowing into the wire from
the field outside. Intuition would seem to tell us
that the electrons get their energy from being
pushed along the wire, so the energy should be
flowing down ~or up! along the wire. But the
theory says that the electrons are really being
pushed by an electric field, which has come from
some charges very far away, and that the electrons
get their energy for generating heat from
these fields. The energy somehow flows from the
distant charges into a wide area of space and then
inward to the wire.’’ ~emphasis added!.
However, the result of such an application
and the resulting energy transfer in the circuit apparently did
not satisfy Feynman. He wrote: ‘‘this theory is obviously
nuts, somehow energy flows from the battery to infinity and
then back into the load, is really strange.’’4 Feynman, however,
did not persist and left the problem for others to find a
reasonable explanation. Can we say more about energy transfer
in this simple circuit?

I am unsure. This page has some of its "facts" wrong in other areas...but without being able to deduce the math, the logic of the above statement seems plausible.
As i find more, i will certainly post it. Thank you for bringing this back up again. With how my regular job has been, finding time and initiative for research is difficult.
Electric currents in solid matter are typically very slow flows. For example, in a copper wire of cross-section 0.5 mm², carrying a current of 5 A, the drift velocity of the electrons is of the order of a millimetre per second. To take a different example, in the near-vacuum inside a cathode ray tube, the electrons travel in near-straight lines ("ballistically") at about a tenth of the speed of light.
However, we know that electrical signals are electromagnetic waves which propagate at very high speed outside the surface of the conductor (moving at the speed of light, as can be deduced from Maxwell's Equations). For example, in AC power lines, the waves of electromagnetic energy propagate rapidly through the space between the wires, moving from a source to a distant load, even though the electrons in the wires only move back and forth over a tiny distance. Although the velocity of the flowing charges is quite low, the associated electromagnetic energy travels at the speed of light.
The nature of these three velocities can be clarified by analogy with the three similar velocities associated with gases. The low drift velocity of charge carriers is analogous to air motions; to wind. The large signal velocity is roughly analogous to the rapid propagation of sound waves, while the large random motion of charges is analogous to heat; to the high thermal velocity of randomly vibrating gas particles.

The generator moves an electric current, but does not create electric charge, which is already present in the conductive wire of its windings. It is somewhat analogous to a water pump, which creates a flow of water but does not create the water inside. Other types of electrical generators exist, based on other electrical phenomena such as piezoelectricity, and magnetohydrodynamics. The construction of a dynamo is similar to that of an electric motor, and all common types of dynamos could work as motors.

Most modern generators with field coils feature a capability known as self-excitation where some of the power output from the rotor is diverted to power the field coils. Additionally the rotor or stator contains a small amount of magnetizable metal, which retains a very weak residual magnetism when the generator is turned off. The generator is turned on with no load connected, and the initial weak field creates a weak flow in the field coils, which in turn begins to slightly affect the rotor to begin to produce current that then further strengthens the field. This feedback loop continues to increase field voltage and output power until the generator reaches its full operating output level.
This initial self-excitation feedback process does not work if the generator is started connected to a load, as the load will quickly dissipate the slight power production of the initial field buildup process.

So to summarize, Morgan's experiment seems to be the first independent confirmation on record of the existence of Wallace's kinemassic field!!! He used a half-integral spin nuclei material (Lead) that is apparently better for demonstrating the kinemassic field due to its higher nucleon number than what Wallace used (mostly Copper) and so he was able to use airgaps about 160 times wider and did not have to confine the field to a closed circuit. He used high angular velocity (95% of Wallace's) which caused a strong spin polarization of the powered flywheel. Morgan's experiment seems to be genuine proof of the existence of Wallace's kinemassic field, and is a much simpler way to test for its existence than Wallace's method. Since it demonstrates that Lead is a superior material for demonstrating kinemassic fields, it seems clear that this is what should be used as well in gravitational experiments related to the kinemassic field (such as [5]), as it is durable and not prohibitively expensive.
Morgan basically seems to have observed a gravitomagnetic version of something called the Einstein-deHaas effect, in which a freely suspended body begins to rotate on being magnetized [6]. The Einstein-deHaas effect is the inverse of Barnett's effect, in which uniform rotation of a body causes a magnetization which is proportional to its angular velocity [6]. In the gravitational Einstein-deHaas effect, a freely suspended body would begin to rotate on being spin polarized by a gravitomagnetic field.

By th way, BFFT, I would like to give you credit for posting an interesting piece of material. I may be very skeptical about the circumstances in which the sensational claims were made and absence of publications, but all in all it's a lot closer to real physics (even if wrong) than the theories of hollow Neptune, breathable atmosphere on the Moon etc. I don't believe in "AC gravity" claims but would gladly read any article, if it ever comes out, that tries to replicate the experiment. I've had enough of the Element 115 bull, your stuff is more interesting

So am I the only one concerned that the Chinese are actually working on Anti Gravity?

Damn it .........sorry about link- thanks Zorgon. As for Chinese being into antigrav- yes I am concerned.
Professor Ulf Leonhardt and Dr Thomas Philbin, from the University of St Andrews in Scotland, have worked out a way of reversing this pheneomenon, known as the Casimir force, so that it repels instead of attracts.
