I have heard of Brown (from physics texts). And I do not doubt that he
built some devices that levitated using EM or electrostatic fields. But
that is not the same as anti-gravity. Also if you do the math yes it is
possible, for small masses. But when you get to something substantial
then it becomes hopeless. However, if you can point me to a paper I'm
quite willing to change my mind if the argument and the data support it.

Just read some of the technical bits of the website you suggested, and
it is as I suspected using electrostatics using a very large charge in a
capacitor.

 From many of the reports it does look like there are very sizable EM
fields involved, but is that the propulsion or a side effect? The only
estimate I ever saw was by James E. Macdonald when he analysed a
sighting by a scientist who happened to be wearing some polaroids and
noticed the halo around the object contained polarised light. This
suggested a value for the magnetic field that would be responsible for
polarising the light. Don't remember what the value was, but it was very
high. But magnetism wont work as a propulsion mechanism either.

The current bandied about buzz word is MFD (Magnetic Field Disruption).
 The articles say things about 250,000 atmospheres of pressure in a
disk like hub with electricity circling the hub in bismuth.  Not sure
if this came from Lazar, the supposed S-1 physicist, or not.

Another told of spinning electrons mechanically because it either
increased their weight due to centrifugal forces involved, or it simply
pushed the little electrons past the speed of light.

I am suspicious that the government may have deep black projects in
this area, but nothing public to prove it other than the 50's reports
on antigravity and the 60's material on T. T. Brown.

I almost forgot, another theory involves one of the rarer elements that
creates minute gravitational effects when stimulated by electricity.
The combined gravitational effects of trillions upon trillions of
stimulated electrons compound the effect into one capable of making
vehicles fly.

All in all, Brown's work seem most documented and workable.  The
capacitor electrostatic effect is a proven fact.  And, the current term
for this phenomena is, I believe, electrogravitic.  If it does, indeed,
work then it could be added to jets or rockets to boost their
performance.  I am not a purist.  If it works, use it.
