Tesla's birthday was 160 years old. Do you still remember his ten inventions?
Editor's note: Nikola Tesla came to this world 160 years ago today. As an inventor, physicist, mechanical engineer, electrical engineer and futurist, he is considered an important promoter of the commercialization of electricity. Its many inventions and patents make it one of the greatest electronics engineers in the United States and even in the world. He was weighed down by Edison and he was fortunate. After experiencing the peak of life, he became more and more eccentric. However, his ultimate dream is simply to provide humankind with inexhaustible free energy. On this occasion, let us relive Tesla's legendary life. On July 10, 1856, Tesla was born in the small Austrian imperial village Smirian (now Croatia). The interest in electronic invention comes from the influence of the mother. Mother Djuka Mandic invents some small home appliances in her spare time. Tesla's father, Milutin Tesla, was a pastor and writer and asked Tesla to follow this path. Obviously, Tesla's interest lies in science. Tesla went to school in Karlovac, Croatia, studied electrical engineering at the Graz University of Technology in Austria in 1875, and then studied at Prague University. In 1881, Tesla came to Budapest and worked in the local telephone exchange. It was in Budapest that Tesla had the idea of ​​an induction motor. After several years of invention attempts, Tesla left Europe at the age of 28 to go to the United States. Tesla in 1880 In 1884, Tesla came to the United States alone. In addition to the letter of recommendation written by former employer Charles Bachler, he had almost nothing. And this letter was written to the business tycoon Thomas Edison. The letter mentioned: "I know two great people, you are one of them, and the other is this young man." Edison was based on direct current electricity. Engineering is quickly becoming the industry standard. He hired Tesla and the two quickly began to work together tirelessly. Edison's inventions also received various improvements. However, just a few months later, the relationship between the two people came to an end. Historians think this is because of their discordant personalities and their disagreement: Edison is very strong, focusing on market and financial success; Tesla is less skilled in business. After parting ways with Edison, Tesla took investment in 1885, and subsequently founded Tesla Electric and Electric Manufacturing Company to start developing improved versions of arc lighting. However, after the success, the investors did not agree with Tesla's plan for the exchange of electric generators, and eventually removed his position, so that Tesla had to earn his living by manual labor during those days. Tesla and Edison's "Current War" However, when it came time to work, Tesla's AC system received attention in 1887, and he also found a partner willing to support Tesla Electric. At the end of the year, Tesla had successfully obtained a number of AC patents. In the end, his AC system attracted the attention of George Westinghouse, an engineer and businessman of Westinghouse Electric Company. He was looking for a way to solve long-distance power supply. After carefully studying the invention of Tesla, George bought the AC patent in 1888 for 60,000 U.S. dollars (cash and stocks) and promised to pay 2.5 US dollars for each horsepower thus produced. With the development of the AC system, Tesla joined Westinghouse in fierce competition with Edison, which aims to sell DC power to the country. Edison had launched negative reports in an attempt to weaken the support that AC received. Tesla did not stop his work and continued to apply for patents, including the famous "Tesla coil." This established an important foundation for later radio technologies. However, it always came. At the Chicago World Expo in 1893, the General Assembly established the electronic product exhibition area for the first time. Westinghouse was responsible for the lighting of the venue. Tesla showed his AC system at the conference. People also saw his fluorescent lamps and single-node light bulbs. In 1895, Tesla designed the first batch of AC hydroelectric generators in Niagara Falls. A year later, Buffalo, New York used AC power and became a global news for a time. With continuous success and praise, AC quickly became an excellent power supply method widely used in the 20th century, and it is still a universal standard in the world. Tesla, obsessed with the wireless transmission of energy, began his most ambitious project in 1900: building a global wireless transmission system - sharing information with the world through huge electric towers and providing electricity for free. In 1901, Tesla took the investor’s 150,000 U.S. dollars into his work. He designed and built a laboratory in Long Island, USA, and was equipped with a generator and a huge transmission tower, which we later known as Wardenk. River Tower. You know, the project investors at that time even included the financial giant JPMorgan Chase Group. The giant tower is also known by the media as "Tesla's Million Building." However, investors gradually became suspicious of the viability of the Tesla project; at the same time, as a competitor, Guillermo Marconi, radio technology has made great progress with the aid of Edison and the steel king Carnegie. . In the end, Tesla had no choice but to give up the project. The staff at Wadden Krefta was disbanded in 1906 and the laboratory was also auctioned off in 1915. Two years later, Tesla declared bankruptcy, the tower was razed, and scrapped to deal with the debt. Warden Creek Tower After experiencing great spiritual suffering, Tesla finally returned to work, mainly engaged in consulting work. But as the times changed, his ideas became more and more weird and unrealistic. He himself has gradually become eccentric and has spent a great deal of time on taking care of the wild pigeons in the New York Park. When he talked about how he wanted to build a powerful "death beam," he even caused the FBI to be on the alert. This did make the Soviet Union in World War II have some interest. On January 7, 1943, Tesla, a poor and destitute, left the world at the New York Hotel alone, at the age of 86. Due to the nature of Tesla’s later inventions and patents, all his research was top secret, and all personal belongings were also sealed at the time. The death ray proposed by Tesla is considered a particle beam weapon. The U.S. government did not find a safe prototype device. According to a document, "There are 80 suitcases reported to be located in different places. There are his research manuscripts and trial plans..." Despite the fact that he was still carrying a large amount of debt when he passed away, after several years, it became clear to everyone that the legacy that Tesla had left was still in use today. In 2008, the non-profit Tesla Science Center was established to restore Tesla's experimental base in Long Island. In May 2013, after many efforts, the organization finally raised enough funds to buy the original site of Warden Crift Tower. At present, the reconstruction work is still in progress. 1, alternating current Needless to say, AC is definitely the beginning of Tesla's business. In spite of Edison's obstruction, Tesla succeeded in bringing us AC. AC power is cheaper and safer than DC power. Tesla proved this with his own body. 2, neon lights Fluorescent lights and neon lights were not invented by Tesla, but he managed to steer and improve the light bulb. As early as 40 years before entering industrial production, Tesla had designed fluorescent lamps in the laboratory. At the 1893 Chicago World's Fair, Tesla's personal exhibition used a neon sign. 3, remote control In 1898, Tesla demonstrated a remotely controllable boat model that used radio waves to operate the propellers and lights. At that time, the ship model was equipped with several large batteries and a radio signal controller. The concept of remote control (or remote automation) has also been widely used by people. 4ã€Induction motor Induction motors use alternating current and consist essentially of a stator and a rotor. The stator remains stationary (no doubt) while using an electromagnet to rotate the middle rotor. Induction motors are considered to be durable and easy to maintain while enjoying low operating costs. In 1888, the Italian inventor Ferrari Bitsil launched his engine two months in advance. However, Tesla's evidence of patent application is more weighty. 5. Adams Power Plant Substation The Niagara Falls Commission has been looking for a company to build hydroelectric power stations in order to use the enormous energy of the waterfall for many years. After witnessing the results of Tesla and Westinghouse Electric, they signed the contract. In 1896, the Adams Power Plant substation began operation and supplied power to Buffalo, New York. Ten more generators were later built to supply electricity to New York City. The power plant is considered to be revolutionary and sets standards for modern hydropower plants. 6, radio The inventor of the radio was a controversial issue. In 1895, Tesla was ready to launch a radio signal at a distance of 50 miles, but his laboratory was burned before this, so the experiment was delayed. Italian Guglielmo Marconi is also doing similar research. After all, the radio invention patent was ultimately owned by Marconi. 7, shadow photography In 1895, the German scientist William Conrad Roentgen discovered a mysterious energy called x-ray. The results of the research published by Roentgen inspired Tesla, who used vacuum tubes to produce X-rays and formed images he called shadowgraphs. Tesla is considered to be the first person in the United States to take an X-ray picture. He took a picture of his foot wearing shoes and sent it to Roentgen to congratulate him on his discovery. 8, Tesla turbine Tesla tested the engine in 1909 and found that it could achieve a combustion efficiency of 60%. What is profound is that at present, we have only obtained a fuel-to-energy conversion rate of 42%. However, because of the nature of the business, fuel sales allow people to gain more benefits, so the piston engine is still the normal state of use today. 9, amplified transmitter In 1899, Tesla created the largest and most powerful Tesla coil and called it an amplifying transmitter. The zoom transmitter has three coils and is 52 feet in diameter. It can generate millions of volts and create "artificial lightning." Lightning can reach as high as 130 feet. It was the largest artificial lightning at the time. 10, Tesla coil In 1891, Tesla invented the Tesla coil. He uses two coils, a primary coil and a secondary coil, each with its own capacitor. And this revolutionary device is Tesla's obsessive power to use radio to power the city. The importance of the Tesla coil is that it makes engineers aware of the nature of electricity and how to use electricity.
