NIKOLA TESLA

NIKOLA TESLA

• WAR BY ELECTRICAL MEANS

Vaclav Netolicky
2

• He was a prophet of the wireless-controlled
  engines of war.
• - Edwin H. Armstrong

War begins

• World War I was sparked by the assasination of an
  Austrian Archduke on Teslas homeland in Sarajevo

4
December 20th 1914

• Tesla published an article in the New York Sun
  titled Nikola Tesla looks to Science Fiction to
  end war
• He felt that war was a physical process whose
  duration could be determined by a mathematical
  equation.

5

• war is essentially a manifestation of energy
  involving the acceleration and retardation of a
  mass by force
• Tesla calculated that the war would last 5 years
• He also felt that the duration of the war could
  be brought to zero with a weapon of sufficient
  magnitude

6
December 8, 1915

• The New York Time published the following
• Nikola Teslahas filed patent applications on
  the essential parts of a machine, the
  possibilities of which test a laymans
  imagination and promise a parallel of Thors
  shooting thunderbolts from the sky to punish
  those who had angered the gods

7

• he is not yet ready to give the details of the
  engine which he says will render fruitless any
  military expedition against a country who
  possesses it.
• All of this meant little to soldiers dying on the
  battlefields

8

• Contrary to popular thinking, new technology was
  only adding to the savagery
• Flame throwers, machine guns, poison guns,
  airplanes, and the tank were introduced
• Tesla was well aware of the war
• He was receiving letters from his family about
  the war

9
Electricity

• Radio was one of the most important innovations
• Troops could now communicate over large distances

10
Radio and the Navy

• Early onboard sets were based on Marconis design
• These had a range of about 60 miles
• Tesla developed a radio for the US Navy
• A five-kilowatt set was capable of sending
  messages 1,500 miles

11
U.S. Naval Radio Service

• A firm used Teslas patents to build a radio
  station for the Navy in New Jersey
• It could operate on several adjacent-frequency
  channels and could transmit in multiplex code
• Signals were received 9,000 miles away
• For 2 years Tesla received 1000/month for these
  patents

12
April 2, 1917

• President Wilson persuades Congress to declare
  war on Germany

13
August 1917

• In an interview with the Electrical Experimenter
  Tesla provided the first technical description of
  what would later be known as radar

14

• the method of locating such hidden metal masses
  as submarines by an electrical rayThat is the
  things that seems to hold great promise. If we
  can shoot out a concentrated ray comprising a
  stream of minute electric charges vibrating
  electrically at tremendous frequency, say
  millions of cycles per second, then intercept
  this ray, after it has been reflected by a
  submarine hull for example, and cause this
  intercepted ray to illuminate a fluorescent
  screen on the same or another ship, then our
  problem of locating the hidden submarine will
  have been solved.

15

• It took twenty more years for Teslas concept of
  radar to be perfected
• The prototype was officially credited to Robert
  A. Watson-Watt of England in 1935
• He was the first to effectively visualize radio
  signals with a cathode ray tube

16
July 4, 1917

• Teslas dream - Wardenclyffe Tower - was blasted
  down with dynamite
• Rumors were spread that spies were hiding there
  to radio information to German U-boats
• Tesla maintains the following

17

• On this occasion I would contradict the widely
  circulated report that the structure was
  demolished by the government, which owing to war
  conditions, might have created prejudices in the
  minds of those who may not know that the papers,
  which thirty years ago conferred upon me the
  honor of American citizenship, are always kept in
  a safeOn the contrary, it was in the interest of
  the Government to preserve it, particularly, as
  it would have made possible - to mention just
  valuable result - the locations of a submarine in
  any part of the world

18
Scientific Outsider

• Tesla now depended on the popular press to
  continue to advance his concepts
• In The Electrical Experimenter Tesla introduced
  the guided ballistic missile

19

• I am now planning aerial machines devoid of
  sustaining planes, ailerons, propellers and other
  external attachments, which will be capable of
  immense speeds and are very likely to furnish
  powerful arguments for peace in the near
  futureBy installing proper plants it will be
  practicable to project a missile of this kind
  into the air and drop it almost on the very spot
  designated, which may thousands of miles away

20
While at Wardenclyffe

• He demonstrated his robot boat to a delegation of
  Japanese
• From a high cliff he directed a tiny vessel into
  Long Island Sound, closed a switch, and caused
  the boat to explode before the eyes of his amazed
  spectators - when the Japanese offered to buy the
  device, Tesla refused to sell it to them

21

• Some people who worked with Tesla were worried
  about the instruments of war he was inventing
• Tesla had just launched several model wireless
  torpedoes in the Sound and caused them to circle
  a ship and return to shore
• Tesla said sometimes I feel that I have not the
  right to do these things.

22
Science Fiction

• But with so many of his ideas that were directed
  by radio waves, people thought they were more the
  stuff of science fiction than of reality.
