Nikola Tesla
continued....
Deciding to better insulate the arrangement in
order that all possible line leakages could be eradicated, he again
attempted the experiment. The knife switch rapidly closed and opened, he
again felt the unpleasant shock just as painfully as before. Right through
the glass shield! Now he was perplexed. Desiring total distance from the
apparatus, he modified the system once more by making it "automatic".
He could freely walk around the room during the
test. He could hold the shield or simply walk without it. A small rotary
spark switch was arranged in place of the hand-held knife switch. The rotary
switch was arranged to interrupt the dynamo current in slow, successive
intervals. The system was actuated, the motor switch cranked it contacts
slowly. Snap ... snap ... snap ... each contact produced the very same
room-filling irritation.
This time it was most intense. Tesla could not
get away from the shocks, regardless of his distance from the apparatus
across his considerably large gallery hall. He scarcely could get near
enough to deactivate the rotating switch. From what he was able to painfully
observe, thin sparks of a bright blue-white color stood straight out of the
line with each electrical contact.
The shock effects were felt far beyond the
visible spark terminations. This seemed to indicate that their potential was
far greater than the voltage applied to the line. A paradox! The dynamo
charge was supplied at a tension of fifteen thousand volts, yet the stinging
sparks were characteristics of electrostatic discharges exceeding some two
hundred fifty thousand volts. Somehow this input current was being
transformed into a much higher voltage by an unknown process. No natural
explanation could be found. No scientific explanation sufficed. There was
simply not enough data on the phenomenon for an answer. And Tesla knew that
this was no ordinary phenomenon. Somewhere in the heart of this activity was
a deep natural secret. Secrets of this kind always opened humanity into new
revolutions.
Tesla considered
this strange voltage multiplying effect from several viewpoints. The problem
centered around the fact that there was no magnetic induction taking place.
Transformers raise or lower voltage when current is changing. Here were
impulses. Change was happening during the impulse. But there was no
transformer in the circuit. No wires were close enough for magnetic
inductions to take place. Without magnetic induction, there could
theoretically be no transformation effect. No conversion from low to high
voltage at all. Yet, each switch snap brought both the radiating blue-white
sparks and their painful sting.
IMPULSES
Tesla noted that the strange sparks were more
like electrostatic discharges. If the sparks had been direct current arcs
reaching from the test line, he would surely have been killed with the very
first close of the switch. The physical pressure and stinging pain of these
sparks across such distances could not be explained. This phenomenon had
never been reported by those who should have seen and felt its activities.
Tesla gradually came to the conclusion that the
shock effect was something new, something never before observed. He further
concluded that the effect was never seen before because no one had ever
constructed such a powerful impulse generator. No one had ever reported the
phenomenon be cause no one had ever generated the phenomenon. Tesla once
envisioned a vortex of pure energy while looking into a sunset. The result
of this great Providential vision was Polyphase current. A true revelation.
But this, this was an original discovery found through an accident. It was
an empirical discovery of enormous significance. Here was a new electrical
force, an utterly new species of electrical force, which should have been
incorporated into the electrical equations of James Clerk Maxwell.
Surprisingly, it was not.
Tesla now questioned his own knowledge. He
questioned the foundations on which he had placed so much confidence in the
last several years. Maxwell was the "rule and measure" by which all of
Tesla's Polyphase generators had been constructed. Tesla penetrated the
validity of Maxwell's mathematical method. It was well known that Maxwell
had derived his mathematical descriptions of electromagnetic induction from
a great collection of available electrical phenomena. Perhaps he had not
studied enough of the phenomena while doing so.
