He was once Edison's subordinate, but in the end he became Edison's lifelong enemy Who is he?

Edison is known for his light bulbs, while promoting light bulbs. Edison also set out to build a look at the company. Specialized in the development of power systems. And the thing Edison had always insisted on was direct current, in 1884. A lad. Walked into Edison's office with a letter of recommendation. And this man will become Edison's biggest competitor.

When the young man first arrived, Edison didn't have a good impression of him, because Edison was an inventor who tried and achieved results repeatedly. And this guy was conceiving everything in his head and liked to solve problems before doing it, but one day, Edison changed his mind about him. On this day, Edison installed an electric light factory on the steamship Olegang. There was a problem with two generators. The repairman told Edison. The motor should be removed and sent to the repair shop for repair. However, at this time, the scheduled departure date of the mooring has passed the time and is obviously not allowed.

Then Edison thought of the boy from Europe. The lad took the tools he needed and boarded the Oregon. It took a whole night to fix two motors. Since then, Edison's impression of him has improved. And gave him more important tasks. Improved his DC generator. He promised to pay him $50,000 after the improvement was successful. Now it's $50,000, which is a big number, and at the time, $50,000 was quite valuable, but when the guy improved the generator, Edison said, Oh, boy, you don't understand our American humor. This is obviously the pie that Edison drew and he wanted to pay for it. But he ignored the boy's stubbornness. The young man left his job angrily,

After leaving Edison. The young man set out to develop an alternating current system that was once rejected by Edison. Mainstream at the time. The view is that dc current is recognized. But one disadvantage of DC is the transmission problem. The power station must be built near the user, otherwise it cannot be used. Alternating current, on the other hand, excels in transmission. Less power is lost. At this time, Westinghouse took a fancy to his ALTERNA system, and Edison sensed the threat of AC to him. Start denigrating alternating current. He found stray cats and dogs. Electrocuted with alternating current. Shoot the bamboo shoots! At that time, there was obviously no animal protection organization in the United States, otherwise Edison would have been sued in court. Well. The promotion of alternating currents was hampered by Edison's denigration. But it was gold that always shone, and the Chicago Fair gave alternating current a chance. The show needed a stable power system to power all the lights. V Spin House seized the opportunity to take the project at a very low price. The AC cannon was successful at this exhibition. Subsequently, alternating current on the Niagara Falls hydroelectric power plant project at an affordable price. Success. Since then, I have received alternating current.

This man is Nikola Tesla. He was praised by posterity as a god-like man. In 1908, there was a big explosion on the banks of the Tunguska River in the Siberian forests of Russia. Two thousand square kilometers of forest were razed to the ground, most of Europe. Man, in the night sky, saw the flash of daylight. It is more than a thousand times more powerful than the Atomic Bomb of Hiroshima in Japan, and legend has it that this big explosion is related to Tesla. Tesla could have become the richest man in the world with a patent for alternating current, but he gave up the privilege of patents and people used cheap electricity. I Edison is well known. But little is known about his deeds. We should be thankful and remembered. This great scientist.
