I prefer to use the nasty term embedded in the title of this
website, as it tends to lead to one being labelled a "kook",
or worse, a "pseudo-scientist".

I feel it's worth mentioning to the PICList as a whole,
because I think many who haven't seen it may be interested,
and those who have seen it may have some input for me
about how it works/if it works.

Fascinating stuff, really.  In short, applying a high enough
voltage (tens to hundreds of kilovolts) to a capacitor whose
plates have different geometries in the correct orientation
yields a net force sufficient to levitate light objects.

Usually a piece of magnet wire in the same plane as a
piece of metal foil.  The force vector follows that plane,
from the foil to the wire.

The most interesting part is that while no one seems to be
able to provide a really adequate explanation for the physics
involved (at least not one that I wouldn't consider 
"pseudoscientific"), a great deal of experimentation in this
field seems to be occuring in basements and garages
while almost none seems to be occuring on an industrial
scale.
