Nikola Tesla
continued....
Crookes wrote many times to the Royal Society
and to Tesla concerning this fact. Sure that Tesla was a modern Faraday,
Crookes continued espousing the belief that Tesla had discovered the next
historically important electrical advancement. He was encouraged to
continue research despite his protagonists. Few academes trusted Tesla's
methods now. Fewer yet listened any longer to his statements.
Losing credibility
as quickly as he had found it, financiers were slow to trust investing in
his new systems. His inventions continued their steady march into electrical
history. Each new device chronicles a new step in the technology, which
should have changed the world. He plunged himself headlong into work. Only
work would vindicate him. Opinion would fade when others gradually saw the
astounding developments, which he would produce. In these actions, Tesla
revealed his noble and naive nature. The world had changed, but changed
toward a more brutish rule.
BROADCAST POWER
He
set to work developing more powerful embodiments of his initial
Transformers. In order to make a Broadcast Electrical System possible it
would be necessary to devise more efficient transformers. He set to work on
this very task, examining and dissecting every fundamental part of his
existing Transformers.
Tesla discovered that excessive sparking,
though impressive to observers, were actually "lossy instabilities". The
distant radiant effects he desired were interrupted and distorted whenever
sparking occurred. Both sparking and brush discharges actually ruined the
distant broadcast effects of radiant electricity, a situation that had to
be remedied. Tesla sought elimination of the discharges now. Tesla had
already found that metals could focus radiant electrical effects.
Additional stability in his Transformers could be achieved with the addition
of large copper spheres to the active terminals. Tesla considered copper
spheres to be "Aether gas reservoirs", providing his transmitters with an
additional Aether gas supply.
Copper spheres attached to Transformer
terminals reduced the required electrical levels for an efficient electric
radiance. Copper spheres significantly reduced the injurious instabilities
of visually spectacular brush discharges, but did not eliminate them
entirely. What Tesla required was a new means for transmitting the radiant
electricity without loss.
Tests with elevated copper spheres facilitated
efficient transfer of radiant power between the Transformer and surrounding
space. Now, Tesla Transformers became true Tesla Transmitters. Tesla found
it possible to broadcast harmless radiant electricity with great power to
very great distances. Numerous subsequent patents recorded his progressive
conquest of the broadcast power principle.
He succeeded in making radiant electricity safe
for human use. It would simply travel around conductors if made to impulse
quickly enough. Only specially entuned receivers could properly intercept
the radiant power for utility. Not three years before he had accidentally
discovered the radiant electrical effect. He dreamt of safely sending
electrical power without wires in 1892. Now, in 1895, he had realized his
dream. Would the system work across the vast distances, which he envisioned?
He took his more portable Transmitters
outdoors, away from the confines of his South Fifth Street laboratory. Both
in northern Manhattan and Long Island, Tesla tested his radiant broadcast
systems without restriction. He measured the distant radiant electric
effects of these designs in electrostatic volts. Broadcast power could be
converted back into current electricity if so desired, the harmless high
voltage becoming current in appropriate low resistance transformer coils.
He found to his very great surprise that very
distantly positioned vacuum tubes could be lit to great white brilliance
when the primary system was operating. The requirement for this action was
twofold. First both the system and the receivers had to be grounded. Second,
specific volumes of copper had to be connected to the receivers. When these
two requirements were satisfied, lamps maximized their brilliance, and
motors operated with power. Copper in the receiver had to "match" the copper
mass of the transmitter in a very special equivalence, otherwise radiant
transfer would not be efficient. The requirements differed very much from
those of ordinary radio antennas. He also found that elevated copper spheres
more powerfully enhanced the broadcast radiant power from his transmitters.
This was Tesla's means by which his transmitters and receivers could be
better "connected" despite their distance.
