In the following days, Yang Wenli frequently put on a show outside, appearing in a certain place on the street today, and at the home of a citizen tomorrow.

He is very enthusiastic about the people's lives, to see if there are any problems that need to be solved by the government, he is gentle and sincere, always smiling, and has won universal praise from the people.

After the show, life still has to be lived, and Yang Wenli returned to the normal life of a scientific research dog.

"Your Majesty, please see, this is pure copper that we have electrolyzed, do you think it's okay?"

"Hmmm! That's right, that's what it looks like, you see if it's purple, pure copper is very soft, it's the best wire. ”

"Your Majesty, we don't know how much wire we have to draw? Please also be explicit. ”

"This ...... I don't know, the size of the wire is determined by the size of the turbine, and a dam is usually four to six turbines, and only one or two turbines are built in the early stage, and then added in the future when the power is scarce, so that it will not be wasted.

In this way, the turbine is also determined by the scale of electricity consumption in Sapporo City, which requires those who study the theory to calculate, and finally calculate the cross-sectional area of the wire rod as geometric.

Ru Cheng, have the other materials yielded results? ”

"Your Majesty, at present, we have only researched one kind of insulating glue, but we have no test equipment, so we can't determine whether it is insulated or not."

"Generally speaking, all polymer compounds are insulating, and there should be no problem, only the difference in insulation effect.

The test equipment is not available for the time being, and we will definitely develop it in the future. Yang Wenli replied and asked him again: "Is it difficult to make silicon steel sheets?" ”

"It's not very difficult, Your Majesty has clearly stated the composition of the material, the problem is that there are a lot of tests to be done, and it is very time-consuming to smelt a furnace of steel, so we haven't developed a silicon steel sheet yet, please forgive Your Majesty."

"It's normal, it's not our responsibility, but if it goes well, then we have to start building the barrage, and we have to choose the section of the river with strong currents and large water level differences.

I will arrange for the construction department to build it, but you, as Party A, will be responsible for supervision and technical guidance. ”

"Whoa! Your Majesty, don't worry, we'll take the time to see it. ”

Now the most difficult thing left is the high-efficiency permanent magnet, he knows that the best permanent magnet is the NdFeB rare earth permanent magnet, but the key is that he does not know the appearance of the rare earth material neodymium, even if there are rare earths, it is a needle in a haystack, not to mention that he does not have rare earths at present.

In fact, generators are distinguished from excitation generators and permanent magnet generators, each with its own advantages and disadvantages, but in the current period, the advantages of simple structure, easy maintenance and long life of permanent magnet generator are what he needs most.

Of course, there are rare earths in North Korea and the Far East not far from Ezo Island, and they are all large-scale rare earth mines with a scale of hundreds of millions of tons.

Rare earths are a unique type of soil, as if the granite has been extremely weathered, and is generally distributed in layered veins, which is easy to identify.

Although there are no rare earths, the motor can already be designed, and he plans to make preparations with both hands, and design a set of excitation motors and permanent magnet motors, after all, the hope of permanent magnets is too slim.

There are also water turbines, which are also quite difficult, but Yang Wenli is open, and all precision processes can be cast by him, and then finely polished by hand, and the precision is very high.

As soon as he entered the scientific research, Yang Wenli devoted himself to motor design and turbine design, and time flowed away quietly like flowing water.

It wasn't until the mining team sent to the Far East brought back suspected rare earth materials that he got out.

"Good! Good! Good! This should be rare earths, and your task now is to separate all kinds of rare earth materials with all your might.

There are a total of 17 rare metal elements in rare earths, but what we need now is neodymium in the light rare earth lanthanide elements, the specific distinction is very simple, use a balance to weigh the same amount of rare earths, which rare earth is the lightest, which is the lanthanide rare earth, you just need to refine neodymium from the light rare earth. ”

"Your Majesty, but we don't know which element is neodymium? Don't know how to separate? I don't know where to start! Wang Rucheng replied with a bitter face.

"There are only so many elements in total, you try everything, as for how to separate and purify, I don't know, it depends on you to find a way, no matter how easy it is to engage in scientific research, it is difficult, only through continuous experiments can you make achievements, don't complain, go and do it!" That's an order. ”

"Yes" Wang Rucheng was bluffed by Yang Wenli and became honest.

The boron content in the NdFeB strong magnet is very small, only about 2.5%, and borax is sold in major pharmacies.

At present, borax is a special product of Tibet, which has been artificially manufactured since 1563 and exported to the world, which shows that its output is also very large, and there is a sufficient supply of borax.

Since there are rare earths, Yang Wenli gave up the design of the excitation motor and made every effort to design the rare earth permanent magnet generator.

The generator is divided into single-phase, two-phase and three-phase, asynchronous and synchronous, and also divided into AC and DC.

Permanent magnet generator is divided into rotor permanent magnet generator and stator permanent magnet generator, among which the stator permanent magnet generator has the simplest structure, its rotor does not need windings, so it does not need carbon brushes and movable rings, it is very simple, and the heat dissipation is faster, which can reduce the risk of demagnetization and can significantly improve the service life of the generator.

Yang Wenli is standing on the shoulders of giants to make inventions, absorbing the experience of his predecessors, and taking many detours.

It's just that there are a lot of calculations involved, and it's still time-consuming.

During this time, the city of Sapporo entered a benign development trajectory, and today Sapporo has nearly 100,000 citizens, making it a large city in ancient times.

The business here is prosperous, the scenery is beautiful, and the people live and work in peace and contentment, which is a thriving scene.

"Hello! I want to rent a shop in the business district, but I don't know what to do? ”

A man dressed in a kimono politely asked the staff of the government affairs hall.

His dress was very different, except for some old people, few people in the Far Eastern Kingdom wore kimonos now, so the staff asked him suspiciously: "I'm sorry!" Are you a citizen? ”

"I'm from Mutsu and I'm just a businessman, right?"

"I'm sorry! Foreigners are not allowed to rent a shop for business, you can only rent a shop in a bonded area stipulated by the customs. ”

"What? When did I become a foreigner, aren't you also Japanese? It's funny. ”

"Listen, I'm not Japanese, I'm a citizen of the Far Eastern Kingdom, we're just the same people, but we're two separate countries, you know?

Please get out right now, or I'll call the police and arrest you. ”

"You foreigner still want to make money with us, stop dreaming, get out!"

The people who were queuing up in the back heard the conversation between the two and shouted at the Japanese dissatisfied.

"It's really unreasonable, you actually aided the abuse, and you were willing to be a traitor, you will regret it sooner or later." The Japanese blushed and muttered as he walked out.
