Nikola Tesla was born and in the Austrian Empire on July 10, 1856. During college, Tesla worked from 3 a.m to 11 p.m (complain about 9-to-5 now), and the world wasn’t ready for his genius at the time. He is probably one of the greatest scientists and American inventors that have ever lived. His greatness originated by his dedication, but much of his work was underappreciated until after he passed away.
After he moved to New York in June 1884, Nicola’s work and inventions earned him the name of ‘mad scientist’. And you know why? Because most of his inventions were far more futuristic for that century. So here are some of Tesla’s greatest achievements for us all to be thankful.
1. Alternating current
It all began in 1893 at the World’s Expo in Chicago where the feud between Edison’s direct current and Tesla’s alternating current culminated. The direct current, which was invented by Thomas Edison, was very dangerous and costly over long distances.
Tesla sought to implement alternating current for the power grid because it was cheaper and safer. To prove the safety of AC, he reportedly used a Tesla coil to send electricity through himself to produce light. Despite Edison’s and General Electric’s efforts to implement direct current, Tesla won the battle of the currents.
2. First hydro-electric power plant
Nikola Tesla along with George Westinghouse constructed the world’s first hydro-electric power plant at the base of Niagara Falls. The power plant remains to this day as a museum, but it was one of the first energy generation locations that started the process of electrifying the world.
At the time of Tesla’s life, ionizing radiation and electromagnetism were heavily studied subjects. His early experiments with x-ray imaging eventually led to its implementation in the medical field. The discovery of x-rays was one that Tesla found through his quest to understand the unseen forces in the world around him. This drive ultimately is what made Tesla such a profoundly amazing inventor.
4. Tesla’s induction motor
Proclaimed as one of the 10 greatest inventions of all time, Tesla’s induction motor revolutionized was what possible in the appliance industry. It was the first instance where electrical energy could be sustainably converted to mechanical energy. This gave way to compact mixing machines to washing machines among many other things. Essentially all modern electronics that utilize electric motors can thank Tesla for their existence.
5. Measurement of flux density
One of the lesser-knowns of Tesla’s achievements is the foundation of a reliable unit in the measurement of magnetic flux density. Tesla discovered rotating magnetic fields in 1882, which served as a core discovery around the alternating current. Rotating magnetic fields are used in a wide array of fields, with an MRI machine, the forefront of the technology. Tesla was honored with the international unit of flux density used to describe the strength of magnetic fields in 1956.
6. Wireless transmission
One of Tesla’s greatest inventions and predictions of the future was that of wireless data and energy transmission. J.P. Morgan company invested $150,000 into Tesla’s idea of wireless transmission with the goal of finding frequencies which data could transmit across. The tower that Tesla built was the world’s first wireless transmission system, and his ideas in this field laid the groundwork for the possibility of modern wireless data.
Tesla’s genius will go down in history. He was the author of numerous books, developed and designed many devices, but still died in poverty, in January 1943, at the age of 86.
