(Note: As is well known, velocity represents the rotation of an
object out of the normal 3-dimensional space toward a 4th
dimensional direction. The speed of light, c, represents a full
orthogonal turn. A normal electromagnetic wave, being transverse
oscillatory, is a priori limited to a single orthogonal turn,
for that is all it possesses. It thus moves at the speed c. A
longitudinal scalar wave, on the other hand, need not be so
limited at all.)

Brian Brady's experiments obtaining fast, short electrical
lights or sparks from crushing quartz-bearing granite cylinders.
(Comment: Brady's experiments are certainly repeatable, so it is
true that "earthstress lights" can be produced at a distance,
although the piezoelectric effect alone in no way explains the
production of the phenomena outside the piezoelectric crystal.
The fact that UFO's occurring near a fault zone are not
necessarily repeatable simply means that at least one other
major factor must be involved in the production of UFOs than is
involved in the production of earthstress lights. UFOs may
sometimes involve scalar interferometry from a fault zone, but
other causative factors must also be involved. Earthstress
lights, on the other hand, need have no additional causative
factors than what lies in the earth itself.)

signals from separate transmitters that (theoretically at least)
can create a long-lived electrostatic wave that travels in the
ionosphere -- a sort of natural memory device. The coded signals
could then be read out much later when the proper natural
conditions developed. Delays of up to 40 seconds might be
possible with this "ionospheric memory."
