GROUNDWAVE RADIO

The late part of the Nineteenth Century was a rich and productive
time
for the empirical researchers, those who explored the deep mysteries
of ground conduction radio. Such investigation produced a new world
of
possibilities in the Wireless Arts. Experimenters found distinctive
differences when varieties of geometric shapes were simply buried, a
series of discoveries having no satisfactory conventional
explanation.
A great many highly specialized ground "antennas" were developed and
patented during this time period, a technology which provoked both
disbelief and criticism on numerous counts.(Each metal emits it's own
sounds frequency) The very first vocal radio broadcast was engaged by
Nathan B. Stubblefield (1872). Mr. Stubblefield employed special
"earth cells" and long iron rods to transmit strong vocal signals
"with great clarity". These signals traversed a mile or more of
ground, a coordinated conduction wireless system providing telephone
service for a hardworking farm community.

The Stubblefield Radio Method represents an essential technological
mystery. His "earth cells" never wore out, never produced heat in
their telephonic components, and provided "signal ready" power at any
given instant of the day. Being neither activated or assisted by
additional battery power, the system was fully operational around the
clock. Later critics attempted the reduction of the Stubblefield
Radio
System to mere "subsoil conduction" mode of transmission, but remain
completely unable to reproduce the performance to this day.

Mr. Stubblefield repeatedly stated confidence in the fact that his
Radio System was performing an act of modulation, not a transmission
of signal power. The preexisting "electrical waves in the earth", he
firmly stated, were the real energy carriers for his Wireless
Telephone Exchange. The special "earth cells" were connective
terminals, not power antennas; a means by which direct connection
with
the geomantic energy stratum was obtained. In an entirely different
regime of exploration, a regime having nothing whatsoever to do with
waveradio energies, Dr. Nikola Tesla directed the construction of a
massive radiating structure on the northshore of Long Island. His
previous years of experience taught him the secrets concerning
radiant
energy and its effective propagation through the air and space (1892
to 1900). Understanding the means by which radiant energy may be more
effectively beamed down through the ground, Dr. Tesla established the
magnificent Wardenclyffe Station (1901).

Tesla intended Wardenclyffe to be the first of a series, stations for
the subterranean beam transmission of radiant energy. Propagation of
very large diameter radiant energy beams had been found more
effective
for given power purposes, when conducted through solid rock. Tesla
found that the earth was transparent to these penetrating
straightline
beams, and planned the use of deeply imbedded ground terminals in
order to direct and launch his special radiant energy. Dr. Tesla took
special pains to establish the extensive underground conducting
system
in order "to get a grip of the earth". This most complex construction
operation, necessarily executed long before the great tower was
erected, took place below the Power Broadcast Station. Tesla stated
that this was the most difficult part of his construction operation
at
Wardenclyffe, the drilling of long iron pipes having first been
driven
down to more than 300 feet into the foundation rock. At a depth of
120
feet, Tesla excavated several radiating shafts, long hallways whose
internal walls were covered with pitch and surrounded with iron
pipeworks. These shafts extended outward at this horizontal depth for
several hundred feet in all directions, a formidable ground
projector.
Beneath the central chambers of this Magnifying Transmitter, the
deeply embedded terminals actually formed the primary beaming
structure; a bizarre conception which was literally rediscovered in
legal documents.
