Found it. 1994 paper from a Tesla symposium. Was on my old laptop from
2018. It's 1.434 megs .pdf author by "anonymous Ph.Ds," titled THE
"PHILADELPHIA EXPERIMENT" with a 1967 quote from Vannevar Bush. Google
doesn't find that. I think it had been on tucks.nl archive, NOT in the
Corum section. Maybe it's still there? I'd search for Philadelphia, not
Corum, and not Columbi Egg or Stealth. The Corum paper on rotary fields
ends at page ?30? (But this below is the same as the Corums' Columbi Egg
paper, except with all the many pages of figures and appendices included,
pp30-96.)

Idea: once I made a crude test of a "microwave phosphor" that should be
able to see RF shadows. Can it see Philadelphia Experiment?
Rotating drum covered with stripes of LEDs, so the drum surface glows red
when spinning fast. Now let short dipole rectennas on the drum each
connect to many DC buffers which each drive one LED (perhaps forward bias
the rectenna diodes with 0.6V thru choke coils, to eliminate any turn-on
threshold.) The drum needs only two sliprings to provide power.

Shine CW microwaves on the rotating drum (perhaps 20mm waves, or even
shorter.) The "phosphor" is now being lit up by microwaves. Now hold up
your hand, inspect the shape of the shadow. Probably shows fraunhoffer
diffraction rings. Hold up a short wire, and in one orientation it's
invisible, in another it appears as a black disk ~one wavelength in
diameter. Heh, add a poly plastic lens, and now you have a
microwave-imaging camera. Perhaps also provide orthogonal antennas each
with a green LED, so it "sees" both H and V polarized RF as two different
colors. Sell it to Frank Oppenheimer's Exploratorium museum.
To such eyes which can see in the RF bands, how would a partially-working
Philadelphia Experiment appear? Perhaps a big silver ball that reflects
radio, or perhaps a black sphere that absorbs? Supposedly it starts
reflecting visible light if the rotary fields are cranked up fast enough.
(Perhaps employ relatively slow rotation as supposedly used in the ship
experiment, then wobble the fields with a UHF high-watts emitter, perhaps
circularly polarized, to "ride upon" the existing huge b-field coming from
the two quadrature loop antennas? If nonlinear, the two signals don't sum,
but instead the slow one "lifts up" the fast one's amplitude, as a
square-law effect.)

OT: Heh, I also found the Corum BL paper from a Tesla symposium. Many
have created Ball Lightning, finding that they're not plasma and not
electrical. They are welding-spatter, like a weighty metal aerogel or
percolation-structure. They are "fire-balls" as Tesla stated, but a weird
form of fire akin to a dense hot aerogel; a low-density blob of
fuel-oxidizer, like a nearly solid chunk of acetylene. Disturb it too
much, and it goes from slow burning glow to extremely violent explosion.
When you have your own pet lightning-ball, don't poke at it, or it gets
angry and bites. (But there are more than one form of BL, and perhaps
some are combinations of this aerogel welding-spatter stuff, plus added
plasma, or at least some high-volt capacitive double-layer effects.)

Hi William, the "missing" Corum rotary-fields paper from 1994 proceedings of
the Tesla Symposium - the url no longer works. Thanks for the Corum
pointers, though, really good stuff. What I'm wondering is, might you have
the missing corum rotary fields paper yourself?
