Quote - but the French found it very difficult to reproduce Faraday's experiments,

I don't know if you are reffering to Faraday's hokopolar generator or to Faraday's experiments.
Faraday was a pioner, but his homopolar generator is not a laboratory experiment, is something real and working device. if you wish you can purchase an industrial version. Usualy are used for soldering and also are used as the energy source of "star war" lasers.
Homopolar geneartors are not a mystery, any high school technician can understand how it work, the only problem is that contradict Relativity, but as it work and are useful Einstein is ignored.
Dogma is only applied by scientists and academics and not by technicians, industry and business.
If something works and is useful, we can ignore God, do it and make money....

Quote - Those damned conspiratory Physicists hid that from the rest of us! Darn them!  The Luminiferous Aesther hypothesis has been adequately dismissed in experimental tests in the past hundred and more years.  There is no measurable medium through which EM waves/particles propagate - they propagate through the space-time continuum itself as best determined.

Is not a question of the aether  the problem is absolute or relative motion. The aether is an abstraction of something mystic that is at absolute rest,
Einstein said that is impossible to know the absolute speed of something, science found long time ago the absolute speed of Earth, value that agree with the measured relative to the background radiation and backaground radiation was only discovered recently.

Quote - And the experiments that I've seen of so-called 'antigravity' involve other well-known factors or fraud.

Many experiments produced very insignificant values that can be attributed to measurement errors and other sources not taken into account, but recently were some some experiment that produced a significative loss of weight that cannot be explained, so it remains as explication antigravity, gravitation shielding or some new and unknown force.

Quote - The value of g (gravitational acceleration on the surface of Earth) varies for many reasons - density, distance from the center (which isn't exactly the same over the planet since it is an oblate sphere - like all planets).  g may vary, but there is no place where it is 2g or 0.5g (ON THE SURFACE OF THE PLANET mind you).

Experiments at the same place! If you measure the gravitaion constant measuring the force between two bodies you achieve one value, if you measure it by geological means you achieve a value slight different, it suggest that the gravitation constant has a different value for short and long range.

Quote - Current observations agree that the speed of gravity propagation is the same as the speed of light.  Next you'll tell me that Newton was correct concerning 'instantaneous action at a distance'.

General Realtivity tell that is the speed of light, but the absence of gravitation force aberration suggest that is infinite or very high. Laplace gave a value 10 millions time the speed of light, other authors gives other values anyway is bery big. The direction of the force of the Sun on the Earth points to the real loaction of the Sun and not to the direction that we see the Sun (delayed by 8 mitus that the light must travel from the Sun to Earth).

Quote - Big, HMMMMM...  Cars 'climb up hill' because of an illusion.  The hill appears to be uphill due to surrounding references.  In reality the hill has a downward slope.  It has been evidenced.

Some cases were proven that are an illusion, but most cases are real The explanation that are an illusion are the same as when someone see an UFO and then comes an astronomers and explain that it was planet VEnus, of course planet Venus flying in formation.
Much better, logical and rationa explanation is that the mountain has a very gig amount of iron or that have magnetic materials, but this is not enough to explain.

Quote - This is why 'cold-fusion' is bunk.

Cold fusion is not dead, still are doing experiments. many have failed and many had success, but nobody is able to explain until now.

Quote - For instance, you mention super-conductors.  Um, electricity (electrons) moves at LESS THAN the 'c' (speed of light - EM propagation) in solids despite their high conductivity.  Super-conductors just increase that speed a bit - but it is still LESS THAN 'c'.  If you are under the allusion that electricity travels at 'c' through circuit traces and wires and whatnot, you need to retake that course in Physics.

I said tlight and not the electron. The speed of light is defined by two constants and this constants are not fixed, but defined by the properties of the medium in which travels the light or electromagnetic wave and also depend on the frecuency of the wave (Maxwell is more complete than Einstein). THere are no rstrictions for the values that these constants can have, so it is always possible, at least in theory, to find a nedium in which an electromagnetic wave of some frecuency travel faster than the speed of light in vacuum.
Einstein stated that the maximun speed is the speed of light in vacuum, but never proved this statement neither gave proves why it must be, it is only a dogma, a question of faith....
Superconductors exclude magnetic field inside, so are perfectly diamagnetic with a permeability zero. By Maxwell light must travel at infinite speed inside a superconductor.
I asked this question because I never heard of such experiment, I am only curious of the results. It doesn't matter the result, in any case or Einstein or the supeconductor theory needs to be explained better.

Stupidity also evolves!
