This time, I want to introduce a talented scientist-nikola tesla.
His name is nikola tesla (1856- 1943). 1856, 10 was born in Smilian, Croatia, the former Yugoslavia in July. His father was a pastor of a church and grew up in a Christian family. 1880 After graduating from Prague University, he immigrated to the United States. 1884 became an American citizen and obtained honorary doctorates from Yale University and Columbia University. There are countless inventions in his life, such as: 1882. Shortly after Edison invented direct current (DC), he invented alternating current, made the world's first alternator, and pioneered multiphase power generation technology. 1895, he made generator sets for Nicaragua Power Station in the United States, making the power station still one of the world-famous hydropower stations. 1897, he made Marconi's theory of "wireless communication" come true. 1898 invented radio remote control technology and obtained a patent (U.S. PatentNo. #6 13.809). 1899, he invented the x-ray photography technology. Other inventions include: radio, radar, fax machine, vacuum tube, neon tube, etc. Even the unit of magnetic line density named after him (1 Tesla = 10000 gauss) shows his contribution to magnetism. Why does such an extraordinary scientist never seem to be recorded in history? No one ever said that? The answer is that his other "unknown inventions" have made great contributions to mankind, but at the same time, they have also prompted many "money-making" enterprises to close down instantly. So his name will be erased forever.
The Heresy of the Times: The Invention of Alternating Current
Readers imagine everyone returning to 1888, when many newspapers reported that Thomas Edison, a famous inventor of direct current, claimed that Nicholas? Nikola tesla is a heresy in the scientific field. His invention of alternating current (AC) directly affected the safety of human life, and showed many times how dogs and cats died instantly after passing AC (thus inspiring the "electric chair" death penalty).
When people think that "experts" are equal to authority, "experts" will not hide the facts for their own selfish interests. Even you are destined to be Nicholas? Nikola tesla is indeed a "heresy" in science.
But in fact, today, everyone knows how much the world needs "AC". The invention of "alternating current" has improved people's lives, promoted industrial development and promoted "scientific progress". But why did Edison attack alternating current and its inventor Nicholas again and again? What about nikola tesla? The answer is that the emergence of "alternating current" directly threatened Edison's "direct current" career. Because the use of "direct current" has too many shortcomings and limitations. For example, "direct current" is not conducive to long-distance transmission, and power stations will be added every 1 km, but "alternating current" can be converted into long-distance transmission through transformers. The relative use of "direct current" is also more expensive, and its efficiency and effectiveness are far less than that of "alternating current". Based on the conflict of interest, Edison started the struggle with Tesla.
So, he invented 24 new designs for the great scientist "Edison", and the design of DC generator was patented by Edison and mass-produced. However, the reward of his efforts is only ruthless deception and ridicule. As a result, Tesla felt very angry and left Edison and his company from the beginning. This is also the prelude to the current war in history.
1888, Tesla got George, the entrepreneur of Westing House. Westinghouse supported the development of the invention of alternating current buried in his mind for six years. Half a year later, he applied for a patent for his own "alternator" and was invited by the American Institute of Electrical Engineers to explain and demonstrate the research results of "alternating current" power generation. Because the performance of "alternating current" is better than "direct current", "alternating current" has also been widely used and gradually replaced the traditional "direct current". Under the threat of serious commercial interests, Tesla was attacked by Edison and branded as a "scientific heresy", and a cruel "scientific persecution" was born. Although "alternating current" has become the mainstream of industrial and social power supply today, even "alternating current" has become a necessity in our daily life, bringing incomparable convenience and happiness. But what about Nicholas? Nikola tesla's name has been forgotten, and it has never even been restored. This is a masterpiece of orthodox science.
A century-old Nicaragua hydropower station
If you have been to Niagara Falls in the United States, I believe everyone will sincerely admire this magnificent spectacle.
Tens of thousands of tons of river water gathered from all directions and poured down in the form of landslides. The rumble of the sudden impact of the river is really daunting. In this endless river, there are unexpected rich resources.
1897, the world-famous "Nicaragua" hydropower station, the first 65438+ million horsepower power station, was built here. Two years later, it became the main power supply in Buffalo, new york, 35 kilometers away. Since then, a dozen power stations, large and small, have been built one after another. As a result, the power generated by hydropower stations is enough to supply a quarter of the total demand in New York State and Ontario, Canada, and its power generation is really amazing. This electric power construction, which lasted for more than 100 years, is still running as usual and has never stopped producing a steady stream of natural gas energy, which is a major symbol of human science in the past hundred years.
But have you ever wondered who invented and designed this great power supply facility?
It turns out that the centenary of this science was built by the talented scientist Tesla in his thirties, in which * * * used his nine patented inventions. With the invention of Tesla's alternator and AC transmission technology, it not only provides more power output to improve the needs of human life, but also brings "power science" to another realm.
In fact, at that time, industry and commerce, street lamps and residential buildings all used expensive "direct current". Because of the loss in the circuit, it is necessary to build a generator set every kilometer when using "direct current". Therefore, it is almost impossible to transmit electricity to Buffalo, new york, 35 kilometers away in the form of "direct current" when building the "Nicaraguan" hydropower station. However, when Tesla, a genius scientist, built the "Nicaragua" hydropower station, he adopted the "alternating current" power supply and transmission technology invented by him, and transmitted the power farther and wider by voltage conversion. As a result, his epoch-making invention realized people's dream of long-distance power supply through the "Nicaragua" hydropower station, and electricity consumption brought people a convenient and cheap life.
Later, in order to commemorate Tesla's contribution, a bronze statue of Tesla was erected in the park next to Nicaragua Waterfall to praise his contribution to Nicaragua Hydropower Station.
