Tangning figured out the key to building a power plant, but to really implement it, there is still a lot of work to do. So he said to Faraday: "Teacher, I want to set up an electric power company and it requires a lot of electrical engineers. I wonder if you are interested in coming and guiding me?"

Faraday was very frank and sighed: "Based on the entire power use plan you just proposed, I probably have nothing to guide you."

Tang Ning: "The teacher is too modest. I can be the chief engineer in the industry, but you are still good at experimenting. My theory is just about theory. If you are in charge of the laboratory work, first realize the ideas I proposed, and then I will find a way to realize factory production. It is the strengths of each person!"

Faraday was a little excited: "You mean, have you not experimented with that AC motor yet? Then I can put down my work and study it specifically. This concept is very creative, and just thinking about it makes me excited."

Tang Ning: "Uh... teacher, wait first, let's go step by step. First, the alternator, then the application of lights, cables, and lighting will make the power company's business bigger and have the financial resources to do the next step, that is, the alternator motor." This order cannot be wrong, otherwise a good business will become a scientific hobby.

From her husband's expression, the old lady who doesn't understand electricity also saw the young man's energy. Nowadays, there are not many people who can make the old man excited and become an old man. She smiled and said, "You have to listen to Xiao Tangning to make a lot of money!"

Tang Ning smiled and accepted this statement, with the expression of a boy who was scattered.

Before leaving, Tangning took out a small gift, a wireless telegraph machine. Now, the entire London is covered with a transmission tower. The centralized centralized distribution plan allows the telegraph machine to be connected to the telegraph network with a small antenna, so that Professor Faraday can contact him at any time. Telegraph machines with typewriters are so easy to use. Teach them for three or five minutes to learn to send telegraphs. Downing also taught Faraday to use telegraph machines to buy the latest telegraph. The cost of a telegraph machine is one hundred pounds a year, which is not a big expense for a quasi-middle class like Faraday, so he has not got it yet. He just applied to the Royal Academy of Sciences and has not yet approved it.

I almost forgot one very important thing - looking for a rubber factory. Faraday happily told Downing the name of a larger rubber factory, and there was also a very important information that the holder of the vulcanized rubber patent in the UK was Thomas Hancock.

Hancock and his business partner McIntosh actually had their own large booth at the World Industrial Expo, displaying their boots, clothes and other rubber products. But at that time, Downing didn't expect to cooperate with them.

The day after Faraday got the printer, he couldn't help but disassemble the machine and study it. Then he saw many magical things like him, which had never been seen in contemporary electrical and magnetism, such as: vacuum tubes.

This kind of electronic component opens the door to the entire electronic age, and it will not appear until long after Changming of the electrical science. In 1883, Edison sealed a metal wire into the bulb in an experiment to improve the light bulb, so he accidentally found that the current flowed from the filament through the gap to the metal wire. Because this phenomenon was not beneficial to Edison's improvement of the light bulb, and he was a person who valued effectiveness, so he only wrote down this effect in his notebook and forgot in the future. However, after the electron was discovered, the Edison effect became very important. It can be used to explain that the current in the void is a beam of flowing electrons. Experiments conducted by British physicist Richardson between 1900 and 1903 proved that electrons would "jump out" from the filament heated in vacuum. This result made him win the Nobel Prize in Physics in 1928.

In 1904, British electrical engineer Fu Leming made full use of the Edison effect and achieved brilliant results. He surrounded the cylindrical metal plate (called the plate electrode) around the bulb filament (called the filament pole). The plate electrode has two functions: when it is at a positive potential, it attracts electrons that jump out of the hot filament, forming a path for current flow; when the plate electrode is at a negative potential, it repels electrons and blocks the current flow. Assuming that the plate electrode is connected to an AC power supply and the current flows in one direction, the plate electrode is positively charged, then the electric power is

The current is unobstructed in the lamp tube; if the current direction changes, the plate pole will be negatively charged, and there will be no current in the lamp tube. Therefore, the function of the plate pole is to only allow current in one direction to pass through. In other words, it can convert alternating current into direct current. Since this tube is very similar to a current valve, the British naturally directly called it "valve", while the Americans call it "tube", which is translated as "vacuum tube" in Chinese. Because it has two electrodes - the wire pole and the plate pole, scientists call it diode.

Vacuum tubes (also known as radio vacuum tubes, because they were originally applied to radios) control the flow of electrons in the vacuum tubes, rather than the current through the wires. Since electrons are easier to control tightly than currents, the vacuum tubes and all the devices derived from them can play a role that cannot be played by circuit devices in the past, opening up a new field for electronic devices. All research and application of vacuum tubes and their descendants is collectively called electronics.

At that time, people used the simplest form of vacuum tube to replace the crystals and serve as a new rectifier because its reliability was higher than that of the crystal. In 1907, American inventor De Forrest further improved and placed the third electrode in the vacuum tube. From then on, the transistor was born. The third electrode (gate) is a metal plate full of small holes, located between the wire pole and the plate. It can attract electrons and accelerate the flow of electrons from the wire pole to the plate (through the small holes on the gate). Therefore, as long as a small amount of positive charge is added to the gate, the electrons flowing from the wire pole to the plate will increase a lot. In this way, even if an extremely weak radio signal is added, the current will also increase a large amount of current, and this current can completely reflect the various changes in the radio waves added to the gate.

This is the big secret of the wireless telegraph. It is impossible for Master Faraday to see through the great secret that has surpassed the times for so many years. Faraday keenly felt the core role of the vacuum tube, but this thing was not mentioned in Tangning's patent application. It can be seen that this young man is extremely terrified. Since he wants to keep it secret, he is embarrassed to ask directly, well, in the end, working with him, and after waiting for a long time, he might accidentally leak the secrets.

When Faraday "disassembled the machine" in the house, before he could reinstall it, Tangning came with another of his epoch-making products - tungsten electric lights.

Faraday was embarrassed, his old face turned red, and said, "I'm very curious..."

Tang Ning smiled slightly and said nothing. It was not that he didn't want to say it, but he had to treat this killer that started the electronic age as a reserved program. This is the most powerful weapon for him to hold the highest power in the "state-owned enterprise" of the British Telegraph Company. No one can understand the secret of the vacuum tube for one day. He is the leader of the British Telegraph Company, and no one can do it.

Teacher Faraday finally decided. Downing was very happy to announce his equity distribution plan. Faraday and the team he led enjoyed a 30% equity pool, of which Faraday owned half: 15%, the president and chief scientist. Other equity was used to reward future outstanding engineers and scientists. He himself invested 80,000 pounds to hold 40% of the shares, and served as chairman and chief engineer. The other 30% were found for other investors. This "other investor" is a matter of particularity, not everyone can do it. Downing's particularity is to ask the financiers with the most connected Lloyds Insurance Company to invest.

Lloyds Insurance Company was originally a cafe near the Thames River in London in 1688. Merchants often talked about transactions here and gradually developed into a trading place for maritime insurance and shipping businesses. Because the founder of the cafe was Edward Lloyd, it was named. In 1769, the cafe was replaced by Thomas Fielding, and was still under the name of Lloyd and gradually developed into an international insurance market.

In the era of using open flame lighting, fire insurance is a major business of insurance companies, perhaps second only to ship insurance. The building of Lloyds Insurance Company itself suffered a major fire in 1838, and a lot of information was destroyed. It was not until 1844 that it was rebuilt. Even if it was a shipwreck, there was a high probability that it was caused by the fire of the ship. The biggest advantage of electric lights is that it will greatly reduce the probability of fire. When people who introduced Lloyds Insurance Company to invest in the power company, they will promote electric light lighting as quickly as possible, because Tangning's idea was that the premiums for ship insurance and fire insurance that did not use electric light lighting would increase! This is the best and most powerful advertisement. What's more, after the radio navigation function is released in the future, it can be used to deal with ships, which is really "highly particular".
