1. 1. The high-pressure fault of the air conditioner caused the protection shutdown. The reason may be that the weather is too hot, the radiator of the outdoor unit is dirty and blocked, and the heat can not be dissipated. It is for this reason that the machine can only be started after the power is removed for a few minutes. After the shutdown, the pressure is restored to balance, and the machine cools down, so it can be started. It is recommended to clean the radiator of outdoor unit and spray water with clean water or air conditioner cleaning agent. 2. Fan problem. If the air conditioning compressor and Freon are basically normal when the machine is just started, check whether the speed of the external fan is normal. If the external fan doesn't run or the speed becomes slow, the normal operation of the air conditioner will be affected. The current will increase and the load of the air conditioner will be too heavy.
2. I don't know about bitcoin, but the principle of bitcoin in China is: collect the upload bandwidth you don't normally use, and give you the equivalent ore in return according to the upload situation Usually, only download bandwidth is used to surf the Internet, but upload bandwidth is wasted)
the major app stores have also launched traffic mining apps, which can monitor traffic reporting.
the major app stores have also launched traffic mining apps, which can monitor traffic reporting.
3. The price of bitcoin has gone up abruptly, and the old miners who left the mine have begun to return. Many new people have also poured into the mining instry. However, the price has gone up, and the difficulty of mining bitcoin is also rising. How can we make money from mining now
- - talking about the mining cost of bitcoin -
the first thing to consider is the cost if you want to make money. If the profit is greater than the cost, it is worth doing. We all know how much bitcoin costs, so let's calculate the cost
1. Mining machine cost: the "number" of bitcoin is a problem-solving process, which can't be calculated by human brain alone. Therefore, mining people need to buy mining machines and keep calculating. The more mining machines, the stronger the computing power
2. Electricity charges: mining machines are big consumers of high power. How much electricity does it consume? Let's put it this way. At present, the electricity consumption of bitcoin and Ethereum mining has surpassed Jordan, Iceland, Libya and other small countries, ranking 71st among all countries and regions in the world. You want to cry when electricity is expensive
3. The rent of the place where the mining machine is placed: because the mining machine consumes a lot of electricity, the power supply load of ordinary residential buildings can not be guaranteed at all, so the mining must rent a commercial site separately, and the rent is much more expensive than that of ordinary residential buildings
4. Operation cost: in order to ensure the computing power, the high-power mining machine needs to work 24 hours, which requires someone to maintain it at any time. When the mining machine is in trouble, the cost of hiring someone is required; At the same time, the mining machine is very delicate. If it is too hot or too cold, the vegetables will be stopped. Therefore, the measures of cold air and cold water insulation are needed to help the mining machine run. This is another expense
5. Mining machine update cost: because bitcoin is becoming more and more difficult to dig, the machine that was able to dig a month ago may not be able to dig anything today, and the market will also launch mining machines with greater computing power. The original mining machine is not worth money immediately. If you want to maintain computing power, you need to buy mining machines again
the above bitcoin mining costs all have a marginal effect, that is, the larger the volume is, the lower the corresponding cost will be. Therefore, some super large mines have been built
bitcoin g in the mine will enter the mine pool and be distributed by all participants. Large mines will be built in places where labor and electricity are cheap, such as Venezuela, the legendary miner's paradise, or Iceland, where the climate is favorable and electricity is cheap
as for the cost, everyone will be different. Let's take a look at an average: in 2017, according to the data of elite fixtures, a research institution, Venezuela is the cheapest of 115 mining countries, which is 513 US dollars, while South Korea is the most expensive, which is 26170 us dollars
China's mining cost is US $3172, which is relatively low among 115 countries. However, the cost is an average value. Large mines with low electricity prices must be much lower. If you are a lone ranger, the cost will rise sharply
in a word, if you really want to make money by mining, first of all, unless you are rich enough to build a mine with thousands of machines, you'd better join a mine to dig together. Although you have to share the money, it's still appropriate in the long run because it can greatly rece costs and improve computing power
secondly, whether you dig by yourself or join the mine, you must choose the place with low electricity cost, and the city with abundant hydropower resources is preferred, because hydropower is the cheapest source of power generation in China at present.

Thomas Alva Edison (February 11, 1847 - October 18, 1931) was born in Milan, Ohio and died in West Orange, New Jersey. Inventors, entrepreneurs
Edison was the first person in the history of mankind to use mass proction principle and electrical engineering research laboratory to engage in invention patent, which had a profound impact on the world. His invention of gramophone, film camera and electric lamp had a great influence on the world. He has more than 2000 inventions and more than 1000 patents in his life. Edison was named the ninth of the 100 influential figures in the United States by Atlantic Monthly, an authoritative American Journal At the end of 1868, Edison came to Boston as a telegraph operator. In the same year, he obtained the first patent right for his invention, which is a device that automatically records the number of votes, or "vote counter". Edison believed that this device would speed up the work of Congress and be popular, But a congressman told him that sometimes voting slowly was also out of political need, so Edison decided never to create inventions that people didn't need The main achievements of Edison are as follows:1, phonograph
in 1877, Edison found that the diaphragm in the telephone microphone would vibrate with the sound of speech, so he took a short needle for experiment, and got a lot of inspiration from it. The speed of speaking can make the short needle vibrate differently. Then, on the contrary, this kind of vibration must be able to make the original voice, so he began to study the problem of voice reproction
Electric light is contrary to people's common understanding, the original inventor of electric light is not Edison, Edison improved electric light. As early as 1801, a British chemist named Humphrey David used platinum wire to electrify light in his laboratory In 1889, Edison invented a kind of motion picture camera. This kind of camera uses a sharp gear to drive a 19 mm wide tape without holes. Under the control of ratchet, it drives the tape to move intermittently and punch holes at the same time In 1910, Edison invented a film camera composed of a phonograph and a camera. Under the power of the motor, the shading crankshaft of the camera is connected with the phonograph, and the phonograph can record sound when the camera is running. During the projection, the phonograph runs synchronously with the picture, making the sound and image appear at the same timesource: Internet - Edison
6. Edison only went to primary school for three months in his life. His knowledge came from his mother's teaching and self-study. His success should be attributed to his mother's understanding and patient teaching since childhood, which made Edison, who was originally regarded as an incompetent child, become a world-famous "king of invention" when he grew up. Edison was curious about many things since he was a child, and liked to experiment with them himself until he understood the truth. When he grew up, he devoted himself to research and invention according to his own interests. He set up a laboratory in New Jersey and invented more than 2000 kinds of things in his life, such as electric lamp, telegraph, phonograph, video camera, magnetic separator, crusher and so on. Edison's strong research spirit made him make great contribution to the improvement of human life style
"waste, the biggest waste is to waste time." Edison often said to his assistant“ Life is too short. Think more and do more with less time. "
one day, Edison was working in the laboratory. He handed his assistant an empty glass bulb without a light port and said, "you measure the capacity of the bulb." He bowed his head to work again
after a long time, he asked, "what's the capacity?" He didn't hear the answer. He turned his head and saw his assistant measuring the perimeter and inclination of the bulb with a tape measure. He took the measured number and put it on the table to calculate. He said, "time, time, how do you spend so much time?" Edison came over, picked up the empty light bulb, filled it with water, handed it to his assistant, and said, "pour the water in the measuring glass, and tell me its capacity right away."
the assistant immediately read out the number
Edison said, "what an easy way to measure. It's accurate and time-saving. Why can't you think of it? Is it not a waste of time? "
the assistant blushed
Edison murmured: "life is too short, too short. Save time and do more things!"< Before he became famous, Edison was a poor worker. Once, his old friend met him in the street and said with concern, "look, this overcoat on you is not in good condition. You should replace it with a new one."
"do you need it? No one knows me in New York Edison answered with indifference. A few years later, Eddie became a great inventor< One day, Edison met his friend on the street of New York“ "Oh," exclaimed the friend, "Why are you still wearing this old coat? This time, you need a new one anyway“ Do you need it? Everyone here already knows me. " Edison still answered with indifference<
the story of Edison's invention of electric light
before the advent of electric light, the commonly used lighting tools were kerosene lamp or gas lamp. This kind of lamp burns kerosene or gas, so it has strong black smoke and pungent odor, and it is very inconvenient to add fuel and clean the lampshade frequently. What's more, this kind of lamp is easy to cause fire and disaster. For many years, many scientists have tried their best to invent a safe and convenient electric lamp< In the early 19th century, a British chemist made the world's first arc lamp with 2000 batteries and two carbon rods. But this light is too strong, can only be installed in the street or square, ordinary families can not use. Countless scientists have racked their brains to make a kind of cheap and rable household electric lamp
this day has finally arrived. On October 21, 1879, an American inventor finally lit the world's first electric lamp with practical value through long-term repeated experiments. Since then, the inventor's name, like the electric lamp he invented, has entered thousands of households. He is Edison, who was praised as the "king of invention" by later generations< On February 11, 1847, Edison was born in Milan, Ohio, USA. In his life, he only studied in school for three months, but he was diligent in learning and thinking. His invention created more than 1000 kinds of achievements, such as electric lamp, phonograph, film camera, etc., and made great contributions to mankind< When Edison was 12 years old, he was addicted to scientific experiments. After tireless self-study and experiments, at the age of 16, he invented the automatic telegraph that sends one signal per hour. Later, he successively invented the automatic counting machine, the first practical typewriter, double and quadruple telegraph, automatic telephone and phonograph. Edison was not satisfied with these inventions. In September 1878, Edison decided to attack the fort of electric lighting. He read a lot of books about electric lighting, determined to proce cheap, rable, safe and convenient electric lights
he started with the white heat lamp. Put a small piece of heat-resistant material in a glass bubble, and when the current burns it to white heat, it will glow from heat. He first thought of carbon, so he put a small piece of carbon wire into the glass bubble. As soon as he was electrified, it broke
"what's the reason?" Edison picked up the broken carbon wire and looked at the glass bubble. After a long time, he suddenly thought, "Oh, maybe because there is air in it, and the oxygen in the air helps the carbon wire burn, so it breaks immediately!" So he used his hand-made ventilator to pump the air out of the glass bubble as much as possible. As soon as the power was on, it didn't turn off immediately. But eight minutes later, the light went out< In any case, Edison finally found that white heat lamp is very important in vacuum, and the key is carbon wire, which is the crux of the problem
what kind of heat-resistant material should we choose<
Edison thought, the highest melting point, strong heat resistance, to be platinum! So Edison and his assistants tried platinum several times, but although this kind of platinum with high melting point prolonged the light-emitting time a lot, it was still not ideal to automatically turn off and then light up from time to time< Not discouraged, Edison continued his experimental work. He has tried barium, titanium, Gu and other rare metals, the effect is not very ideal
after a period of time, Edison made a summary of the previous experimental work and wrote down all kinds of heat-resistant materials he could think of, with a total of 1600 kinds
next, he and his assistants began to test these 1600 kinds of heat-resistant materials in different categories. We can try them again and again. Platinum is the best choice. Due to the improvement of the air extraction method, the vacuum degree in the glass bulb is higher, and the service life of the lamp has been extended to 2 hours. But the price of this kind of lamp made of platinum is too expensive. Who is willing to spend so much money to buy an electric lamp that only takes two hours<
the experimental work fell into a low ebb. Edison was very distressed. One cold winter, Edison was sitting around the fire, looking at the blazing charcoal fire. He couldn't help saying to himself, "charcoal..."
the charcoal strips made of charcoal have been tried. What should we do? Edison felt hot and dry, so he pulled off the scarf on his neck. Seeing the scarf made of cotton yarn, Edison suddenly had an idea in his mind:
Yes! The fiber of cotton yarn is better than that of wood. Can we use this material
he quickly pulled a cotton yarn from his scarf and baked it on the fire for a long time. The cotton yarn turned into charred charcoal. He carefully put the carbon wire into the glass bubble, a test, the effect is really good<
Edison was very happy, and then he made a lot of carbon fibers made of cotton yarn, and carried out many tests continuously. The life of the lamp was extended by 13 hours at a time, and then by 45 hours
as soon as the news spread, it caused a sensation all over the world. The stock price of London gas fell sharply, and the gas instry was in chaos. People have a premonition that lighting gas lamps will become history, and the future will be the era of electricity and light
everyone congratulated Edison one after another, but lovely Edison didn't look happy. He shook his head and said, "no, we have to find other materials!"
"why can't it be on for 45 hours?" The assistant asked in surprise“ no way! I hope it lights for 1000 hours, preferably 16000 hours! " Edison replied
as you all know, it's good to light up for more than 1000 hours. What materials are suitable for you<
Edison had the number in his mind by this time. According to the nature of cotton yarn, he decided to look for new materials from the aspect of plant fiber< So the marathon experiment began again. Edison experimented with all kinds of plant materials as long as they could be found. He even experimented with horse manes, human hair and beards as filaments. Finally, Edison chose bamboo. Before the experiment, he took out a piece of bamboo, looked at it with a microscope, and jumped up with joy. As a result, the carbonized bamboo filament is put into the glass bubble, and after being electrified, this kind of bamboo filament light bulb lights continuously for 1200 hours< At last, Edison was relieved, and his assistants congratulated him one after another, but he said seriously, "there are many bamboos in different parts of the world, and their structures are different. We should choose them carefully!"<
the assistants were deeply moved by Edison's scientific attitude of striving for perfection, and they volunteered to go to various places for investigation. After comparison, a kind of bamboo proced in Japan is the most suitable, so it is imported from Japan in large quantities. At the same time, Edison opened a power plant and set up wires. After a while, the American people began to use this cheap and rable bamboo light bulb< The bamboo filament lamp has been used for many years. It was not until 1906 that Edison switched to tungsten wire, which improved the quality of the light bulb and has been used to this day
when people light up the electric light, they often think of this great inventor, who brings endless light to the darkness. In 1979, the United States spent millions of dollars on a year long commemoration to commemorate Edison's invention of the electric light

7. In the morning, the cold engine temperature is low, the consistency of engine lubricating oil and diesel oil is very high, the diesel atomization is not good, of course, it is not good to ignite. If there is a preheating system, it is better to turn on the preheating engine first, and then ignite when the water temperature rises to more than 20 ℃.
8. Edison's success is mainly e to his own diligence, but it is also permeated with his wife's hard work
Edison married twice in his life. The first wife was Mary steelwell, and the second was Mina
in order to make Edison's life regular and not affect his health, Mary is very considerate to him. She often cooked delicious meals and sent them to Edison's laboratory as soon as the meal was ready; Stay up late at night, and send him a midnight snack; When Mary came home in the middle of the night, she made coffee and prepared bread for him; It's going to be cold. Mary has already made a woolen coat for Edison; It's too hot in summer. Mary cleans and irons all the clothes Edison often changes... Edison has been happy in spirit and devoted himself to the cause of science since he had the help of Mary, and his inventions are more abundant and varied
one summer, Mary took her children to the countryside for a holiday, and Edison stayed in New York alone to do research and development. Before the holiday was over, Mary fell ill. In order not to affect her husband's work, she did not let anyone tell Edison. Later, as the disease got worse, the doctor wrote a letter to Edison without telling her
Mina is no less concerned about Edison than Mary. She knew that Edison often forgot to eat and sleep, so she paid special attention to it. He had to be stopped every morning to finish his milk. Sometimes Edison couldn't go home because he was busy, so she took the meal to the laboratory and watched him finish before he left. I don't know how many times, Mina is angry with Edison for letting the food cool
Mina is outgoing and very concerned about her husband's career. She accompanied her husband to attend the World Expo held in France. With her literary talent and words, this modest inventor was deeply understood and respected by the people of the world
once, she came back from London. Because of the long and bumpy journey, she felt very tired and went to bed early. But when she learned that her husband's activity film had been successfully developed, she felt sleepy and quickly got out of bed to express her warmest congratulations to her husband
Mina's influence on Edison is multifaceted. In order to make Edison rest in the busy and tense work, she often accompanied her husband to the theatre, which was really the only recreation for Edison. Mina is also literate in art and deeply understands her husband's aesthetic views. Not only in her husband's dress and color, she made her solemn and generous, simple and beautiful, but more importantly, this simple beauty formed the purpose of Edison's invention and design. Therefore, Edison's design is always a perfect combination of science and art
when Edison was sick in bed, Mina picked flowers from the courtyard every day and put them beside Edison's bed. At the same time, she will decorate the first floor of the lounge souvenirs, often placed in Edison can see the place, let him enjoy, in order to eliminate loneliness. The sick Edison felt warm when he saw the souvenirs he had won. Mina takes care of Edison's life very carefully. She especially shows Edison the commemorative medallion in the living room. Whenever Edison held the commemorative medallion presented by various countries in his hand, he would think of the research days of his youth and his colorful life in the past
Edison is a great scientist respected by all mankind. Of course, his success is mainly e to his diligence and creative ability. However, his wife also played a very important role
Edison created a lot of material wealth for mankind. In 1922, according to the statistics of the US Congress, Edison increased the tax revenue of the US government by US $1.5 billion within 50 years. According to the 1928 survey, The amount of capital in the world spent on the business related to his invention is as follows:
tramcar 6.5 billion yuan
electric light 5 billion yuan
Movie 1.25 billion yuan
telephone 1 billion yuan
power transmission 857 million yuan
telegraph 350 million yuan
tiejingong 271 million yuan
vehicle workshop 190 million yuan
sound storage 150 million yuan
electric power 100 million yuan
electric installation 3700 million yuan The total amount is 15.725 billion yuan. His relationship with modern material civilization is clear, and his position in the 20th century is clear
Edison's invention has a great influence not only in the United States, but also in the world. America is proud of Edison. The United States Congress awarded him a medal of honor. "The United States is the most prosperous country in the world because there is an Edison in the United States," said Ford, the automobile king of the United States In general, the technological development in the United States can be outlined by Edison. Before Edison, American technology was basically copied from Europe; After Edison, the United States had its own technology. Therefore, Edison is a symbol of the turning point of American technological development
the world will never forget such a great man as Edison who benefits mankind. Edison's invention is on display in the American Museum of fame. At present, historians in New Jersey are still studying Edison's invention and its influence. Edison's invention and creation is the common wealth of mankind, and his great contribution to mankind will go down in history forever
Edison's inventions have enriched people's lives, but these inventions are not the whole content of his great achievements. If he did not invent the phonograph, film, electric light, telephone, etc., which he invented or made practical, sooner or later others would have created them. These things can already be imagined by people at the level of science at that time. The problem is how to turn the imagination into concrete devices. Edison went beyond simple invention. He realized the instrial proction of new invention. Before him, people thought that invention was just the proct of fate
Edison made inventions according to actual needs. He proved to people that invention was not the proct of luck or sudden insanity. To invent something, we must work hard and think hard
Edison's greatest contribution to science is that "he brought the idea that science should always progress." He showed people that "dedicated researchers, through collective or indivial efforts, will certainly be able to make human vision more open."<
Edison only went to primary school for three months in his life. His knowledge came from his mother's teaching and self-study. His success should be attributed to his mother's understanding and patient teaching since childhood, which made Edison, who was originally regarded as an incompetent child, become a world-famous "king of invention" when he grew up
Edison was curious about many things since he was a child, and he liked to experiment with them himself until he understood the truth. When he grew up, he devoted himself to research and invention according to his own interests. He set up a laboratory in New Jersey and invented more than 2000 kinds of things in his life, such as electric lamp, telegraph, phonograph, video camera, magnetic separator, crusher and so on. Edison's strong research spirit made him make great contribution to the improvement of human life style
"waste, the biggest waste is to waste time." Edison often said to his assistant“ Life is too short. Think more and do more with less time. "
one day, Edison was working in the laboratory. He handed his assistant an empty glass bulb without a light port and said, "you measure the capacity of the bulb." He bowed his head to work again
after a long time, he asked, "what's the capacity?" He didn't hear the answer. He turned his head and saw his assistant measuring the perimeter and inclination of the bulb with a tape measure. He took the measured number and put it on the table to calculate. He said, "time, time, how do you spend so much time?" Edison came over, picked up the empty light bulb, filled it with water, handed it to his assistant, and said, "pour the water in the measuring glass, and tell me its capacity right away."
the assistant immediately read out the number<
Edison said, "what an easy way to measure. It's accurate and time-saving. Why can't you think of it? Is it not a waste of time? "
the assistant blushed<
Edison murmured: "life is too short, too short. Save time and do more things!"< Before he became famous, Edison was a poor worker. Once, his old friend met him in the street and said with concern, "look, this overcoat on you is not in good condition. You should replace it with a new one."
"do you need it? No one knows me in New York Edison answered with indifference
a few years later, Eddie has become a great inventor< One day, Edison met his friend on the street of New York“ "Oh," exclaimed the friend, "Why are you still wearing this old coat? This time, you need a new one anyway
"do you need it? Everyone here already knows me. " Edison still answered with indifference<
Edison's story: making the sun
one snowy night, Edison's mother suddenly fell ill, and his father rushed to the doctor. The doctor said, "your mother has acute appendicitis and needs an operation.". At that time, there was only oil lamp, but no electric lamp. The light of the oil lamp was very dark, and it would be wrong if you were not careful. Edison suddenly thought of a good way, he took out all the oil lamps at home, and then put a mirror behind the oil lamp to let the doctor finish the operation smoothly. The doctor said, "son, you saved your mother with your wisdom and cleverness." Edison took his mother's hand and said, "Mom, I want to make a night's sun."<
the story of Edison when he was a child:
when Edison was young, once he saw a hen hatch and give birth to a chick. He felt wonderful, but he was not satisfied. Afterwards, he also quietly saved some eggs and put them in the warehouse. He leaned on them and tried to give birth to chickens himself, which made the whole family unable to find him for a long time
after he went to school at the age of seven, his strong thirst for knowledge and habit of studying problems became more obvious. He is always endlessly asking questions about the things he comes into contact with and asking the teacher to answer them clearly. In this regard, the teacher felt headache. Once in an arithmetic class, the teacher taught the students that two plus two equals four. Edison must let the teacher understand why two plus two equals four. Although the teacher gave him a general explanation, it didn't meet his requirements. So the teacher said he was "stupid". Edison was not satisfied with the knowledge he had learned, but always explored the secrets of nature with his naive mind. However, his teacher failed to understand him. But decades later, Edison became a famous inventor<
the story of Edison: never satisfied
we know that Edison had more than 1000 inventions in his life, and some of them have been surprisingly successful. He is also famous himself. However, he never inlged in his own invention, he was always there
Edison married twice in his life. The first wife was Mary steelwell, and the second was Mina
in order to make Edison's life regular and not affect his health, Mary is very considerate to him. She often cooked delicious meals and sent them to Edison's laboratory as soon as the meal was ready; Stay up late at night, and send him a midnight snack; When Mary came home in the middle of the night, she made coffee and prepared bread for him; It's going to be cold. Mary has already made a woolen coat for Edison; It's too hot in summer. Mary cleans and irons all the clothes Edison often changes... Edison has been happy in spirit and devoted himself to the cause of science since he had the help of Mary, and his inventions are more abundant and varied
one summer, Mary took her children to the countryside for a holiday, and Edison stayed in New York alone to do research and development. Before the holiday was over, Mary fell ill. In order not to affect her husband's work, she did not let anyone tell Edison. Later, as the disease got worse, the doctor wrote a letter to Edison without telling her
Mina is no less concerned about Edison than Mary. She knew that Edison often forgot to eat and sleep, so she paid special attention to it. He had to be stopped every morning to finish his milk. Sometimes Edison couldn't go home because he was busy, so she took the meal to the laboratory and watched him finish before he left. I don't know how many times, Mina is angry with Edison for letting the food cool
Mina is outgoing and very concerned about her husband's career. She accompanied her husband to attend the World Expo held in France. With her literary talent and words, this modest inventor was deeply understood and respected by the people of the world
once, she came back from London. Because of the long and bumpy journey, she felt very tired and went to bed early. But when she learned that her husband's activity film had been successfully developed, she felt sleepy and quickly got out of bed to express her warmest congratulations to her husband
Mina's influence on Edison is multifaceted. In order to make Edison rest in the busy and tense work, she often accompanied her husband to the theatre, which was really the only recreation for Edison. Mina is also literate in art and deeply understands her husband's aesthetic views. Not only in her husband's dress and color, she made her solemn and generous, simple and beautiful, but more importantly, this simple beauty formed the purpose of Edison's invention and design. Therefore, Edison's design is always a perfect combination of science and art
when Edison was sick in bed, Mina picked flowers from the courtyard every day and put them beside Edison's bed. At the same time, she will decorate the first floor of the lounge souvenirs, often placed in Edison can see the place, let him enjoy, in order to eliminate loneliness. The sick Edison felt warm when he saw the souvenirs he had won. Mina takes care of Edison's life very carefully. She especially shows Edison the commemorative medallion in the living room. Whenever Edison held the commemorative medallion presented by various countries in his hand, he would think of the research days of his youth and his colorful life in the past
Edison is a great scientist respected by all mankind. Of course, his success is mainly e to his diligence and creative ability. However, his wife also played a very important role
Edison created a lot of material wealth for mankind. In 1922, according to the statistics of the US Congress, Edison increased the tax revenue of the US government by US $1.5 billion within 50 years. According to the 1928 survey, The amount of capital in the world spent on the business related to his invention is as follows:
tramcar 6.5 billion yuan
electric light 5 billion yuan
Movie 1.25 billion yuan
telephone 1 billion yuan
power transmission 857 million yuan
telegraph 350 million yuan
tiejingong 271 million yuan
vehicle workshop 190 million yuan
sound storage 150 million yuan
electric power 100 million yuan
electric installation 3700 million yuan The total amount is 15.725 billion yuan. His relationship with modern material civilization is clear, and his position in the 20th century is clear
