=Nikola Tesla=

Life Story
Nikola Tesla was born at midnight on July 9, 1856 in Smiljin Lika, Croatia. His mother had never gone to school and his dad was a priest. This happened right when a lightning storm struck. Nikola invented the first ever wheel without paddles at four years old. He loved to work in the dark. He would always have his blinds down, except for during lightning storms. During which he would open the blinds, sit on the couch and talk to himself. He would explain a whole invention to himself while picturing it in his mind. Some say this helped his electrical inventions. Nikola had very keen senses. He claimed he could tell someone was wacthing him from 12 feet away by geting a tingling feeling in the back of his neck. Also he says a fly landing on the table makes a thud noise, and a carriage 1 mile away shakes his whole body. This man could always envsion things that were not real. He had imagained entire planets for him to travel to. He had talked to people who, to him were as real as real life. As he grew older he started to invent things and would test them in his mind. His visions were so accurate that he could tell if his machine was out of balance, because of this, Nikola never built a prototype. He claimed after 20 years of visualization he never had a failed product. His plans always worked like they had in his visions. In 1884 Nikola came to the United States to work for Tomas Edison's compony and redesign Edison's blueprints. Before he got on the ship to go to America, he was robbed of his money, belongings and his ticket. The captan let him board the shp even without a ticket. When he arrived he had 4 cents, a bunch of his poems, a article about science and his sketch for a flying machine. Nikola Tesla worked for Thomas Edison from 10:30 am to 5:00 am the next day. That is 18:30 hours straight!! Even though Tesla did not like Edison's idea current motors, he would get $50,000 for redesigning Edisons blueprints. When he finally did, Edison refused to give him any money. Tesla wanted the 50 grand so he could start hs own lab. After that a group of inventors came up to him and offer him a brand new company called Tesla Electric Light Company. Tesla then made a much better light then what was beng used. He then got the lights patented and installed them around his town. All was well until Tesla's investors took the company from him. Now he had no job or money. Tesla was not able to get a engineering job, so he worked for street gangs. He would go and build streets and dig ditches. During this time, Nikola was able to work on his inventions and get more patents. Most of his things did not come to fame very quickly. He discovered how to turn heat energy into energy for machines and electricity but, he was never given credit for ths because it was "rediscovered" in the 1970's.He considered this the most depressing time of his life.

Conspiracy theories Tesla claimed he could build a Earthquake machine. According to him this device (a pocket sized machine) was able to create man-made earthquakes. he said: "I was experimenting with vibrations. I had one of my machines going and I wanted to see if I could get it in tune with the building. I put it up notch after notch . There was a peculiar cracking sound. I asked my assistants where the sound came from. They did not know.I put the machine up a few more notches. There was a louder cracking sound. I knew I was approaching the vibration of the steel building. I pushed the machine a little harder. Suddenly all the heavy machinery started flying around. I grabbed a hammer and broke the machine. The building would have been falling aound our ears in a few minutes. Outside in the streets there was pandemonium. The police and ambulance had arrived. I told my assistants to say nothing. We told the police it must have been a earthquake. That's all they ever knew." This small device was a big terror and some people asked him if he may use it to destroy the Empire State Building. He replied: "Vibrations can do anything. It would be necessary to step up the vibrations of the machine to fit the natural vibration of the building and the building will come crashing own. That's why soldiers break step crossing a bridge."

Tesla's Death Ray Tesla could also ( in theory) build a Death Ray. It was the theory that the boarders of any country could be surrounded by many large towers. Each tower would have a generator to power the Death Ray. Anyone who tried to approach the line will be picked up on the towers radar. The machine will send a beam of energy through the air. The beam would destroy 10,000 airplanes from 250 miles away! This would definitely defend the country. Tesla claimed that this device would make war impossible to happen. It could defend every country like a giant invisible wall. Any country lined with these would be able to be defended from air strikes and big land armies. Tesla tried to sell Great Britain the machine for $3,000,000 and would have it up and running in three months. They refused and chose to stick to the radar and spitfire tactic. After he failed to sell them the machine he succesfully sold it to the Soviet Union for $25,000, but never gave it to them.



Other Inventions

AC or Alternating Currents

Alternating current is another way to say motor. Any older type of motor run on magnets. One never moves the other does. Some motors have electromagnets, they do not get weaker like the other magnets do. They have to work off currents to be magnetic pull at all. The electromagnets are normally put, this way the north-south sides will alternate in each of the rings. Some types of motor have a spinning center or inner array, while others spin on the outside and have a nonmoving center. To get a motor to work and not be a big lump of metel, it must keep swiching the electromagnets north-south polarity. This makes the rotor(the thing that makes a motor work) have no time to stop. If the rotor was to stop than the motor would be useless. The two poles are pulled closer and closer together, when they almost touch the poles switch and the sides are put back apart.

The Tesla Coil Tesla tried to investigate electricity like high-frequency electricity and high-voltage electricity. In doing this, he invented the Tesla Coil witch streched the limits of the understanding electricity. The device was US patent No. 454,622 (1891) and was to be used in new lighting systems. To work it needed something to give power, a fairly big capacitor, the coil itself and spark-gap electrodes that are adjustable. Now you may be wondering, what do things very specific things do? The Capacitors and the coil do the exact posite things, kind of like conductors and insulators. Capacitors store up energy in itself, while wth the coil the voltage is released. To get these to work Tesla made little sparks jump across a adjustable distance with a electrode on both ends.

Tesla's Radio

The earler radios had to have a transmitter that can produce, amplify and radiate power to make a rado frequency. While doing this putting some kind of information in to the signal. There also has to be a reciever that can get the information. After physics had improved to a point were it could even begin to understand electromagnetic waves, htey still had to topple the big fact of having to acheive very high frequencies and high voltage to even begn to make radio transmissions. Tesla got both of these with his Tesla Coils. Even though he did this it was not untill 1906 that Lee De Forest invented the Electric Vacuum Tube that the radio was neatened up.
