Biography
Nikola
Tesla symbolizes a unifying force and inspiration for all nations in the
name of peace and science. He was a true visionary far ahead of his
contemporaries in the field of scientific development.
New York State and many other states in the USA proclaimed July
10, Tesla’s birthday- Nikola Tesla Day.
Many
United States Congressmen gave speeches in the House of Representatives
on July 10, 1990 celebrating the 134th anniversary of scientist-inventor
Nikola Tesla. Senator Levine from Michigan spoke in the US Senate on the
same occasion.
The
street sign “Nikola Tesla Corner” was recently placed on the corner
of the 40th Street and 6th Avenue in Manhattan. There is a large photo
of Tesla in the Statue of Liberty Museum. The Liberty Science Center in
Jersey City, New Jersey has a daily science demonstration of the Tesla
Coil creating a million volts of electricity before the spectators eyes.
Many books were written about Tesla : Prodigal
Genius: The Life of Nikola Tesla by John J. O’Neill
and Margaret Cheney’s book Tesla:
Man out of Time has contributed significantly to his fame. A
documentary film Nikola Tesla, The Genius Who Lit the World, produced by the Tesla
Memorial Society and the Nikola Tesla Museum in Belgrade, The Secret of Nikola Tesla (Orson Welles), BBC Film Masters
of the Ionosphere are other tributes to the great genius.
Nikola
Tesla was born on July 10, 1856 in Smiljan, Lika,
which was then part of
the Austo-Hungarian Empire, region of Croatia. His father, Milutin Tesla was a Serbian Orthodox Priest and
his mother Djuka Mandic was an inventor in her own right of household
appliances. Tesla studied at the Realschule, Karlstadt in 1873, the
Polytechnic Institute in Graz, Austria and the University of Prague. At
first, he intended to specialize in physics and mathematics, but soon he
became fascinated with electricity. He began his career as an electrical
engineer with a telephone company in Budapest in 1881. It was there, as
Tesla was walking with a friend through the city park that the elusive
solution to the rotating magnetic field flashed through his mind. With a
stick, he drew a diagram in the sand explaining to his friend the
principle of the induction motor. Before going to America, Tesla joined
Continental Edison Company in Paris where he designed dynamos. While in
Strassbourg in 1883, he privately built a prototype of the induction
motor and ran it successfully. Unable to interest anyone in Europe in
promoting this radical device, Tesla accepted an offer to work for
Thomas Edison in New York. His childhood dream was to come to America to
harness the power of Niagara Falls.
Young
Nikola Tesla came to the United States in 1884 with an introduction
letter from Charles Batchelor to Thomas Edison: “I know two great
men,” wrote Batchelor, “one is you and the other is this young
man.” Tesla spent the next 59 years of his productive life living in
New York. Tesla set about improving Edison’s line of dynamos while
working in Edison’s lab in New Jersey.
It was here that his divergence of opinion with Edison over
direct current versus alternating current began. This disagreement
climaxed in the war of the currents as Edison fought a losing battle to
protect his investment in direct current equipment and facilities.
Tesla
pointed out the inefficiency of Edison’s direct current electrical
powerhouses that have been
build up and down the Atlantic seaboard. The secret, he felt, lay in the
use of alternating current ,because to him all energies were cyclic. Why
not build generators that would send
electrical energy along distribution lines first one way, than another, in multiple waves using the
polyphase principle?
Edison’s
lamps were weak and inefficient when
supplied by direct current. This system had a severe disadvantage in
that it could not be transported more than two miles due to its
inability to step up to high voltage levels necessary for long distance
transmission. Consequently, a direct current power station was required
at two mile intervals.
Direct
current flows continuously in one direction; alternating current changes
direction 50 or 60 times per second and can be stepped up to vary high
voltage levels, minimizing power loss across great distances. The future
belongs to alternating current.
Nikola
Tesla developed polyphase alternating current system of generators,
motors and transformers and held 40 basic U.S. patents on the system,
which George Westinghouse bought, determined to supply America with the
Tesla system. Edison did not want to lose his DC empire, and a bitter
war ensued. This was the war of the currents between AC and DC. Tesla
-Westinghouse ultimately emerged the victor because AC was a superior
technology. It was a war won for the progress
of both America and the world.
Tesla
introduced his motors and electrical systems in a classic paper, “A
New System of Alternating Current Motors and Transformers” which he
delivered before the American Institute of Electrical Engineers in 1888.
One of the most impressed was the industrialist and inventor George
Westinghouse. One day he visited Tesla’s laboratory and was amazed at
what he saw. Tesla had constructed a model polyphase system consisting
of an alternating current dynamo, step-up and step-down transformers and
A.C. motor at the other end. The perfect partnership between Tesla and
Westinghouse for the nationwide use of electricity in America had begun.
In February
1882, Tesla discovered the rotating magnetic field, a fundamental
principle in physics and the basis of nearly all devices that use
alternating current. Tesla
brilliantly adapted the principle of rotating magnetic field for the
construction of alternating current induction motor and the polyphase
system for the generation, transmission, distribution and use of
electrical power.
Tesla’s A.C. induction motor is widely used throughout the
world in industry
and household appliances. It started the industrial revolution at the
turn of the
century. Electricity today is generated transmitted and converted to
mechanical
power by means of his inventions. Tesla’s greatest achievement is his
polyphase
alternating current system, which is today lighting the entire globe.
Tesla
astonished the world by demonstrating. the wonders of alternating
current electricity at the World Columbian Exposition in Chicago in
1893. Alternating current became standard power in the 20th Century.
This accomplishment changed the world. He designed the first
hydroelectric powerplant in Niagara Falls in 1895, which was the final
victory of alternating current. The
achievement was covered widely in the world press, and Tesla was praised
as a hero world wide. King
Nikola of Montenegro conferred upon him the Order of Danilo.
Tesla was a
pioneer in many fields. The
Tesla coil, which he invented in 1891, is widely used today in radio and
television sets and other electronic equipment.
That year also marked the date of Tesla's United States
citizenship. His
alternating current induction motor is considered one of the ten
greatest discoveries of all time. Among
his discoveries are the fluorescent light , laser beam, wireless
communications, wireless transmission of electrical energy, remote
control, robotics, Tesla’s turbines and vertical take off aircraft.
Tesla is the father of the radio and the modern electrical transmissions
systems. He registered over 700 patents worldwide. His vision included
exploration of solar energy and the power of the sea. He foresaw
interplanetary communications and satellites.
The
Century Magazine published
Tesla's principles of telegraphy without wires, popularizing scientific
lectures given before Franklin Institute in February 1893.
The Electrical
Review in 1896 published X-rays of a man, made by Tesla, with X-ray
tubes of his own design. They
appeared at the same time as when Roentgen announced his discovery of
X-rays. Tesla never
attempted to proclaim priority. Roentgen congratulated Tesla on his sophisticated X-ray
pictures, and Tesla even
wrote Roentgen's name on one of his films.
He experimented with shadowgraphs similar to those that later
were to be used by Wilhelm Rontgen when he discovered X-rays in 1895.
Tesla's countless experiments included work on a carbon button
lamp, on the power of electrical resonance, and on various types of
lightning. Tesla invented
the special vacuum tube which emitted light to be used in photography.
The breadth of
his inventions is demonstrated by his patents for a bladeless steam
turbine based on a spiral flow principle.
Tesla also patented a pump design to operate at extremely high
temperature.
