The old lady's ejaculation made the old man blush and he was very embarrassed.

Tang Ning laughed and said, "How can people understand everything? Professor Faraday's specialty is electricity and magnetism. This radio communication is actually another field. There are traps in my patents, which are specifically confusing to see. But if someone really understands it, there will be real patented technology in it! This is the difference between businessmen and scientists' thinking methods. I guess no one will fully understand it for many years. Of course, the patent cannot be passed. It doesn't matter, it will be passed one day!"

Faraday said dissatisfied: "Didn't your actions hinder the development of science?"

Tangning has his own theory: "Yes, on the surface, this limits the development of science, but it depends on who uses this trick. Good people use it, it is a good thing, and bad people use it, it is a bad thing. Why is it a good thing? For example, only if I adopt this method can I earn the 3 million pounds from Congress and invest 1.5 million pounds into what I think is the most important thing to improve human life - to control sewage. Without my promotion, Congress would not know when it would be willing to spend a lot of effort to build sewers!

Another point is that after the Prime Minister’s reminder, I also found that wireless telegraphs have greatly improved military intelligence and command systems. In this crisis-ridden era of global hegemony, if this thing is not controlled and flows into the hands of evil countries, it will be even more difficult for humans. Professor, do you think my idea makes sense?"

Faraday moved: "I have an idea!"

The old lady: "Good idea, the world is not peaceful, military technology must be controlled well, and it is best to control it in the hands of our country. I support you, young man!"

Tangning: "Well, I have considered that even if Britain is not our motherland, it is also the most suitable country for mastering this technology in the present. Even if the Royal Army does not have this technology, it is the most powerful in the world. But if this technology comes... For example, Russia, the country's desire for territory is endless, and its method of ruling colonies is very barbaric and cannot be compared with Britain. We must prevent countries like Russia from obtaining military high-tech. As for developing human science... other technologies can be done, hey, the popularity of electricity is a good direction. I am already planning to do two things by building sewers - the underground cable channel and the unified London heating system. These two are technologies that can be promoted all over the world."

Faraday: "Oh? Will the cost of building cables in the underground? "

Tangning: "Yes, but because we build with the sewer, it will save a lot of costs. Once built, it will be more durable than on the ground, and those costs will be earned back! Moreover, London is more beautiful and there will be no wires everywhere. Another thing - unified heating is actually related to making London more beautiful. London's climate is humid, and when it's okay, it's full of fog, which is even more amazing in winter. Every household burns fireplaces and black coal, and dust floats in the air. These are harmful to the health of citizens. After unified heating, the coal burned by heating factories must be controlled using special procedures to control coal dust, and can also utilize waste heat discharged from large factories such as iron plants and cement plants, which can save a lot of coal, carbon and firewood, and kill two birds with one stone."

He is indeed the biggest philanthropist in history, and even considered the air problem!

Faraday praised: "What a great idea... is there enough money?"

Tangning said painfully: "So I have to make money desperately! I will put it on the ground first. In short, I must cure the London environment and give the whole world a demonstration. This is also a serious warning. The development of industry does not necessarily bring all benefits. Therefore, we must control the rhythm, develop what should be developed, and control what should be controlled. The benefits that the environment will bring to the country after the environment is comprehensive. For example, if workers live longer, then the economic benefits they bring will be longer. What's more, a clean and beautiful living environment cannot be bought by money. So if you want to make money, don't be healthy, that's a very low-level wrong idea!"

Mr. Faraday also completely fell in love with this young man, and he became more and more pleasing to him. Why is he so enlightened at such a young age?

After having a relationship, the old man cared about the young man’s career: “Are there any solutions to the key issues of power transmission? For example, what should I use to insulate?”

Tangning: "Vulcanized rubber."

Rubber has been just a "toy" used by natives in South America to worship rubber people, and at most it was used by the British as an eraser. Until 1839, Charles Goodeyer invented the method of rubber vulcanization to greatly improve the properties of rubber. Before that, the consumption of rubber was always very low. For example, in 1830, the world's rubber consumption was only 156 tons and all came from Brazil. This is because these natural rubbers will become sticky when the weather is hot and become brittle in winter, so it is not convenient for commercial application. Rubber will withstand heat after vulcanization.

It is cold-resistant, more elastic, and has a qualitative rise in quality, so in the 1950s, the rubber imported from Brazil reached a scale of more than 1,000 tons. The familiar Chinese name "Goodyear" is "Goodyear". Goodyear is a famous Fortune 500 tire company, but it is not Goodyear's own company. This unlucky inventor, like many chemical pioneers, is healthy and is attacked by poisons such as nitric acid and lead oxide, and his business is not going well. In the most important British market, his patent was stolen.

After thinking about it, Faraday praised: "Good idea, rubber is ideal for insulators!" Rubber is something Faraday has studied. He can imagine that the wires are wrapped tightly. The famous Edison's solution is jute, which is a kind of rope, which is far worse than rubber.

Faraday: "The most critical question - do citizens have any demand for electricity?"

Don't joke about the problem of Master Faraday, because by far the largest electricity unit is the Telegraph Company, and they are enough to rely on batteries because - without electric lights, the horsepower of electric motors is too weak. The world's first public power plant was built by Edison. It was because of his invention of white lights that the demand for power plants was found. Lighthouses also have electricity demand, but they are not big and cannot become a big industry.

Tang Ning smiled and said, "No, there must be any in the future. Because - I have invented the electric light, and the teacher will come to me when I have time... Oh, I will send it to you tomorrow. Just take a look and you will understand how great the chance of using electricity will be in the future."

Faraday was shocked and he also had contact with the research on electric lamps, because his teacher, British chemist David, powered the platinum wire in 1801. He also invented the electric candle in 1810, using arc lighting between two carbon rods. The biggest problem with these inventions is that it will not last long and will be broken in a very short time (less than a few hours). So Faraday asked quickly: "How long can your electric lamp last?"

Tangning: "I've used it for a few months."

Faraday didn't believe it: "Didn't burn it?"

Tangning: "Of course! The material I use is tungsten wire. This metal is very heat-resistant and can still be maintained when heated to an incandescent state."

Faraday lowered his head and pondered: "Tungsten wire...tungsten wire...so wonderful! It's amazing! I really want to see..."

As a chemistry master, when Tangning talked about "tungsten", Faraday understood the key point, because tungsten is the metal with the highest melting point.

Tang Ning: "Also, the power of electric motors is not high now, which is also the reason why electricity consumption is not popular. I know there is a way to generate electricity more effectively."

The world's first generator is Faraday's "disk" generator. Anyone who knows a little about electromagnetics knows that cutting magnetic lines in wires will produce current. A brush is connected to the center and edge of the disc. When rotating, it is equivalent to multiple wires cutting magnetic lines one after another, which continuously generates DC power.

Speaking of his proud work and becoming a work, Faraday immediately raised his ears: "What?"

Tang Ning: "The teacher's disc engine has a disadvantage in increasing power - you are using a brush to connect to the flying disc. In this way, the speed is too fast and it cannot be connected, or it may be worn very much. My idea is - no brushes are used. The effect of cutting the magnetic field and turning the magnetic field by itself is the same. We use the method of turning the magnetic field instead of turning the disk! In this way, the speed can be very fast."

Faraday: "Well, I have thought about this, you should know that the current generated in this way is unstable, alternating directions, and alternating current cannot be used..."

Tangning: "Electric lights can use alternating current. Moreover, the magnetic field can be generated by electricity, right? If we use the same AC power to turn on the motor and change the magnetic poles synchronously, then theoretically, the motor can be rotated, right?"

The AC frequency is synchronized with the magnetic pole transformation of the motor! Wow! So great, Faraday was shocked by this idea, the most gorgeous idea he heard tonight.

It made him feel that the other party was not only a genius scientist, but also a genius industrialist's words were still at a later date - Tang Ning said: "The biggest advantage of using alternating current is also the long-distance transmission. It is also based on the transformer principle you discovered by the teacher. A simple single-phase transformer consists of two conductors. When one of the conductive bodies has some irregular current, alternating current or pulsed DC power will pass through, a changing magnetic field will generate an electric potential difference. According to the principle of electromagnetic mutual induction, this changing magnetic field will cause the second conductor to produce an electric potential difference. If the second conductor is part of a closed circuit, the closed circuit will generate current. The power can be transmitted. This continuous electromagnetic oscillation transmission can make the alternating current transport farther than the DC power. If the voltage is raised and then transmitted, it will be better, which will make the electricity lost less during the transmission process."
