Speaking at the conference this weekend was (amongst others) one Ralph Sansbury,associated with the Classical Physics Institute of NY.
Sansbury is the main author of the theory of gravity which I subscribe to, which involves sub-electron (subtron) particles and electrostatic dipoles. The subject of electrostatic dipoles associated with electrons has come up recently in news media and even the FreeRepublic forum:

The thing which is interesting about Sansbury's subtron theory is that it arose from mundane studies of reversable electrostatic fields being generated by currents and could not plausibly be seen as a search for any sort of a back-of-the-book solution to anything involving a preconceived assumption based on "thought experiments". The claim is that electrons are orbital systems like atoms themselves and that electrical tension will stretch those orbits into ellipses rather than circles, which would in fact create a dipole, and that the alignment of those dipoles in their gigantic numbers produces a field.
The study of such dipoles also produces a rational explanation for gravity and I believe also for light, albeit I subscribe to Wal Thornhill's version of that theory more than to Sansbury's. The computed necessary speed of a sub-electron particle would get you to one of the near galaxies in a few seconds. Wal Thornhill believes it is these kinds of particles moving through Dayton Miller's ether which create light waves.
