2. Tesla Biography
Smiljan, Austro-Hungarian Empire, 1856 (nowadays Croatia)-New York, 1943
Father: Serbian Orthodox Priest
Mother: invented household appliances
Graz (Austria) and Prague Universities
Moved to the US in 1884 and started working for Edison
Because of discussions abandoned the company
Won the current distribution because alternating current is easier to distribute than direct current.
Founded his own laboratory in NY.
1899, new lab in Colorado Springs
Around 300 patents worldwide
Died at the Hotel New Yorker due to thrombosis
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.”

3. Edison Biography
Milan, Ohio (1847)-West Orange, New Jersey (1931)Moved to Port Huron, Michigan, at age 7.
Sold candy and newspapers
Got expelled from school sucmacocl
Self-taught
Set an invention factory
Established the first electric power plant in NYC
Invented the incandescent light bulb, electric railroad, DC motors...
Died in 1931 at his house in New Jersey

4. War of Currents (1880s)
Alternating Current (AC) versus Direct Current (DC)
Tesla supported AC
Edison was in favour of DC
Direct current has a constant voltage
Alternating current alternates the voltage throughout time.

5. Problems of Direct Current
Direct current loses voltage over distance
Many generators needed, or a very large amount of voltage needed
Surplus of generators led to pollution and didn’t look good in urban areas
Excess of voltage can be dangerous, people risk electrocution

6. Wardenclyffe tower (also known as Tesla Tower)
It was a wireless transmission station
Was intended to transmit messages and telephony across the Atlantic to England.
Based on his theories of using the Earth as a conductor of the signal.

9. Tesla versus Edison (II)
Notable inventions
Tesla coil, radio, Alternating Current motors, fluorescent light, remote control...
Incandescent light bulb, phonograph, cement making technology...
Method
He got inspired and saw the invention in his mind in detail before constructing it
Trial and error (“Genius is one percent inspiration, ninety-nine percent perspiration”-T. A. Edison)
Death
1943, in debt, alone and in Hotel New Yorker
1931, with friends and family in New Jersey
Nobel Prizes won
Elephants electrocuted 1

10. Tesla versus Edison (III)
Edison electrocuted a 3 ton elephant, Topsy, to demonstrate that AC was dangerous.
In 1915, both Tesla and Edison were going to receive the Nobel Prize for their studies in physics, but none of them won it because they refused to share the award.
