nikola tesla: humanitarian genius
|
|||
|
|
|||
|
excerpted from vol 6, no. 4, "power and resonance", the journal of the
|
|||
|
international tesla society. for further information on the topics
|
|||
|
discussed below: the tesla book co., box 1649, greenville, texas 75401
|
|||
|
|
|||
|
ask any school kid: "who invented radio?" if you get an answer at all it
|
|||
|
will doubtless be marconi - an answer with which all the encyclopedias and
|
|||
|
textbooks agree. or ask most anyone: "who invented the stuff that makes
|
|||
|
your toaster, your stereo, the street lights, the factories and offices
|
|||
|
work?" without hesitation, thomas edison, right? wrong both times. the
|
|||
|
correctly answer is nikola tesla, a person you have probably never heard of.
|
|||
|
there's more. he appears to have discovered x-rays a year before w. k.
|
|||
|
roentgen did in germany, he built a vacuum tube amplifier several years
|
|||
|
before lee de forest did, he was using fluorescent lights in his laboratory
|
|||
|
40 years before the industry "invented" them, and he demonstrated the
|
|||
|
principles used in microwave ovens and radar decades before they became an
|
|||
|
integral part of our society. yet we associate his name with none of them.
|
|||
|
|
|||
|
for about 20 years around the turn of the century, he was known and respected
|
|||
|
in academic circles world wide, corresponding with eminent physicists of his
|
|||
|
day, including albert einstein, quoted and conferred with on matters of
|
|||
|
electrical science, adopted by new york's high society, backed by such
|
|||
|
financial and industrial giants as j. p. morgan, john jacob astor, and george
|
|||
|
westinghouse. he counted as friends eminent artists such as mark twain and
|
|||
|
pianist ignace paderewski. his honorary degrees, major prizes (including the
|
|||
|
nobel), and other citations number in the dozens.
|
|||
|
|
|||
|
tesla was born in smijlan., croatia (now part of yugoslavia) in 1856, the son
|
|||
|
of a clergyman and an inventive mother. he had an extraordinary memory, one
|
|||
|
that made learning six languages easy for him. he entered the polytechnic
|
|||
|
school at gratz, where for four years he studied mathematics, physics and
|
|||
|
mechanics, confounding more than one professor by an understanding of
|
|||
|
electricity, an infant science in those days, that was greater than theirs.
|
|||
|
his practical career started in 1881 in budapest, hungary, where he made his
|
|||
|
first electrical invention, a telephone repeater (the ordinary loudspeaker)
|
|||
|
and conceived the idea of a rotating magnetic field, which later made him
|
|||
|
world famous in its form as the modern induction motor. the polyphase
|
|||
|
induction motor is what provides power to virtually every industrial
|
|||
|
application, from conveyer belts to winches to machine tools.
|
|||
|
|
|||
|
tesla's mental abilities require some mention, since, not only did he have a
|
|||
|
photographic memory, he was able to use creative visualization with an
|
|||
|
uncanny and practical intensity. he describes in his autobiography how he
|
|||
|
was able to visualize a particular apparatus and was then able to actually
|
|||
|
test run the apparatus, disassemble it and check for proper action and wear!
|
|||
|
during the manufacturing phase of his inventions, he would work with all
|
|||
|
blueprints and specifications in his head. the invention invariably
|
|||
|
assembled together without redesign and worked perfectly. tesla slept one to
|
|||
|
2 hours a day and worked continuously on his inventions and theories without
|
|||
|
benefit of ordinary relaxation or vacations. he could judge the dimension of
|
|||
|
an object to a hundredth of an inch and perform difficult computations in his
|
|||
|
head without benefit of slide rule or mathematical tables. far from an
|
|||
|
ivory tower intellectual, he was very much aware of the issues in the world
|
|||
|
around him, made it a point to render his ideas accessable to the general
|
|||
|
public by frequent contributions to the popular press, and to his field by
|
|||
|
numerous lectures and scientific papers.
|
|||
|
|
|||
|
he decided to come to this country in 1884. he brought with him the various
|
|||
|
models of the first induction motors, which, after a brief and unhappy period
|
|||
|
at the edison works, were eventually shown to george westinghouse. it was in
|
|||
|
the westinghouse shops that the induction motor was perfected. numerous
|
|||
|
patents were taken out on this prime invention, all under tesla's name.
|
|||
|
|
|||
|
tesla worked briefly for thomas edison when he first came to the united
|
|||
|
states, creating many improvements on edison's dc motors and generators, but
|
|||
|
left under a cloud of controversy after edison refused to live up to bonus
|
|||
|
and royalty commitments. this was the beginning of a rivalry which was to
|
|||
|
have ugly consequences later when edison and his backers did everything in
|
|||
|
their power to stop the development and installation of tesla's far more
|
|||
|
efficient and practical ac current delivery system and urban power grid.
|
|||
|
edison put together a traveling road show which attempted to portray ac
|
|||
|
current as dangerous, even to the point of electrocuting animals both small
|
|||
|
(puppies) and large (in one case an elephant) in front of large audiences.
|
|||
|
as a result of this propaganda crusade, the state of new york adopted ac
|
|||
|
electrocution as its method of executing convicts. tesla won the battle by
|
|||
|
the demonstration of ac current's safety and usefulness when his apparatus
|
|||
|
illuminated and powered the entire new york world's fair of 1899.
|
|||
|
|
|||
|
tesla's most important work at the end of the nineteenth century was his
|
|||
|
original system of transmission of energy by wireless antenna. in 1900 tesla
|
|||
|
obtained his two fundamental patents on the transmission of true wireless
|
|||
|
energy covering both methods and apparatus and involving he use of four tuned
|
|||
|
circuits. in 1943, the supreme court of the united states granted full
|
|||
|
patent rights to nikola tesla for the invention of the radio, superseding and
|
|||
|
nullifying any prior claim by marconi and others in regards to the
|
|||
|
"fundamental radio patent" it is interesting to note that tesla, in 1898,
|
|||
|
described the transmission of not only the human voice, but images as well
|
|||
|
and later designed and patented devices that evolved into the power supplies
|
|||
|
that operate our present day tv picture tubes. the first primitive radar
|
|||
|
installations in 1934 were built following principles, mainly regarding
|
|||
|
frequency and power level, that were stated by tesla in 1917.
|
|||
|
|
|||
|
in 1889 tesla constructed an experimental station in colorado springswhere he
|
|||
|
studied the characteristics of high frequency or radio frequency alternating
|
|||
|
currents. while there he developed a powerful radio transmitter of unique
|
|||
|
design and also a number of receivers "for individualizing and isolating the
|
|||
|
energy transmitted". he conducted experiments designed to establish the laws
|
|||
|
of radio propagation which are currently being "rediscovered" and verified
|
|||
|
amid some controversy in high energy quantum physics.
|
|||
|
|
|||
|
tesla wrote in century magazine in 1900: "...that communication without wires
|
|||
|
to any point of the globe is practicable. my experiments showed that the air
|
|||
|
at the ordinary pressure became distinctly conducting, and this opened up the
|
|||
|
wonderful prospect of transmitting large amounts of electri- cal energy for
|
|||
|
industrial purposes to great distances without wires...its practical
|
|||
|
consummation would mean that energy would be available for the uses of man at
|
|||
|
any point of the globe. i can conceive of no technical advance which would
|
|||
|
tend to unite the various elements of humanity more effectively than this
|
|||
|
one, or of one which would more add to and more economize human energy..."
|
|||
|
this was written in 1900! after finishing preliminary testing, work was
|
|||
|
begun on a full sized broadcasting station at shoreham, long island. had it
|
|||
|
gone into operation, it would have been able to provide usable amounts of
|
|||
|
electrical power at the receiving circuits. after construction of a
|
|||
|
generator building (still standing) and a 180 foot broadcasting tower
|
|||
|
(dynamited in world war i on the dubious pretext of being a potential
|
|||
|
navigation reference for german u-boats), financial support for the project
|
|||
|
was suddenly withdrawn by j. p. morgan when it became apparent that such a
|
|||
|
worldwide power project couldn't be metered and charged for.
|
|||
|
|
|||
|
another one of tesla's inventions that is familiar to anyone who has ever
|
|||
|
owned an automobile, was patented in 1898 under the name "electrical ignitor
|
|||
|
for gas engines". more commonly known as the automobile ignition system, its
|
|||
|
major component, the ignition coil, remains practically unchanged since its
|
|||
|
introduction into use at the turn of the century.
|
|||
|
|
|||
|
nikola tesla also designed and built prototypes of a unique fuel burning
|
|||
|
rotary engine based upon his earlier design for a rotary pump. recent tests
|
|||
|
that have been carried out on the tesla bladeless disk turbine indicate that,
|
|||
|
if constructed using newly developed high temperature ceramic materials, it
|
|||
|
will rank as the world's most efficient gas engine, out-performing our
|
|||
|
present day piston type internal combustion engines in fuel efficiency,
|
|||
|
longevity, adaptability to different fuels, cost and power to weight ratio.
|
|||
|
|
|||
|
tesla's generosity eventually left him without adequate funds to pursue and
|
|||
|
realize his inventions. his idealism and humanism left him with little
|
|||
|
stomach for the world of industrial and financial intrigue. his new york
|
|||
|
laboratory was destroyed by a mysterious fire. references to his work and
|
|||
|
accomplishments were systematically purged from the scientific literature and
|
|||
|
textbooks. driven into a hermetic exile in a new york hotel during the
|
|||
|
period between the two wars, 20 years of his potentially rich and productive
|
|||
|
contribution were taken from us. the only occasions of public appearance
|
|||
|
were the yearly press interview on his birthday when he would describe
|
|||
|
amazing and far reaching inventions and technological possibilities. these
|
|||
|
were distorted and sensationalized in the popular press, particularly when he
|
|||
|
described advanced weapons systems on the eve of world war ii. he died in
|
|||
|
obscurity in 1943. only the fbi took note: they searched his papers (in
|
|||
|
vain) for the design of the "death-ray machine". it is interesting to note
|
|||
|
that the motivation for our "star wars" defense system was based upon fears
|
|||
|
that the soviets had begun deployment of weapons based upon tesla high energy
|
|||
|
principles. public reports of mysterious "blindings" of u.s. surveillance
|
|||
|
satellites, anomalous high altitude flashes and fireballs, elf wave radio
|
|||
|
interference, and other cases lend credence to this interpretation.
|
|||
|
|
|||
|
credit must be given where credit is due for the labor saving and humani-
|
|||
|
tarian inventions such as universal ac current that have been incorporated
|
|||
|
into the very fabric of our daily lives and also the devices who's design
|
|||
|
have been made available, but have not been utilized by society at large.
