How many workshops are there in Suncheon at dusk?

There are workshops that develop cement, which are now in mass production, but because of the limited transportation, the production speed is slightly slow, and it can only meet the construction outside the customs.

This is not enough.

If it is built outside the gates, won't it be built inside the gates?

Therefore, Dusk is sure that when he returns to Yingtian this time, Zhu Di will force himself to express his position and help him establish the official road from Yingtian to Shuntian, as well as the important towns around these two capitals.

Of course, Dusk will definitely be rewarded from Zhu Di.

He would have been "forced" to agree to let the construction engineering company under Huawei Real Estate contract the rebuilding and expansion of all official roads in the Ming Dynasty, well, excluding Shuzhong.

It's too painful to build a road in Shuzhong.

Anyway, the population of Daming is not large, so it is better to move the population of the remote mountain villas out, gather them together, and then return to colonize them with the progress of science and technology.

The development of cement relied on the advent of a simple ball mill – the Suncheon Ball Mill Workshop has developed the simplest manpower ball mill – and Dusk continues to invest in other power settings for them to consider other power settings, such as hydraulics and electricity.

However, electricity is very complicated and requires electric motors, so we need to find a "technical" meeting with the technicians in the ball mill workshop to determine the general direction and find talents from home and abroad to tackle key problems.

On second thought, it is better to directly set up a motor research and development department.

Hydraulics are simple.

Before the invention of the electric motor, the hydroelectric ball mill was used for a few years, after all, even if a lot of money was invested in research and development, the motor was difficult to get out without five years, ten years or even decades.

The emergence of the manpower ball mill, thanks to the technological progress of the Shuntian steelmaking workshop, has developed a "special steel" with barely qualified performance, because the performance is barely qualified, so the loss of the ball mill is extremely large, the replacement rate is extremely high, so the cost is also huge.

Therefore, after the dusk arrives in Shuntian, we will continue to invest heavily in upgrading superhard special steel, and let steelmakers continue to develop special steels with other properties, in a word, come up with their own ideas, and let economic and industrial demand drive progress.

That's all twilight can do.

On the hydropower side, there is a bottleneck...... The main reason is that the stability of the voltage cannot be controlled, and the technicians have been tackling the problem for two or three years, but they still have not found a solution.

After the dusk patrol, I patted my head and was annoyed.

It's your own fault!

When I set up this hydropower research and development workshop, I was too busy to ignore one thing: the amount of electricity generated by hydropower is huge, which involves the conversion of high and low voltages and the problem of long-distance power transmission.

In fact, it is a transformer problem.

The hydropower station must be several miles away from the city, and for the planning and development of the city, it must be at least dozens of miles away, so it involves the solution of transmission voltage.

The principle of the transformer is simple: the transformer uses the principle of electromagnetic induction to change the AC voltage device, the main components are the primary coil, the secondary coil and the iron core, and the secondary coil is outside the primary coil. When the primary coil is connected with alternating current, the transformer core generates an alternating magnetic field, and the secondary coil generates an induced electromotive force.

This is in middle and high school physics textbooks.

Although simple, electricity is an epoch-making product for Daming, and skilled workers can't think of this problem no matter how whimsical their heads are, so they can't make transformers.

After inspecting the hydropower R&D workshop at dusk, I spent another day discussing with a group of technical backbones for a whole day, explaining the principle of the transformer in detail, and then taking time to help them draw a design schematic.

The next step is to solve the problem of loss in power transmission - the oil industry has not developed, which means that there is no plastic, so what can be used to isolate the wires to ensure the safety of power transmission and reduce losses?

It is definitely not feasible to use porcelain pipes, and between long-distance electric piles, porcelain pipes are too heavy.

With lacquer?

The safety is low, and it doesn't seem to reduce much loss.

After thinking about it, I finally decided to use rubber.

Rubber this thing is a special product of Malaysia, the current Ming Dynasty, basically the Siamese territory of the Manraka Kingdom is abundant, with the development of overseas trade in the Song and Yuan dynasties, although the Ming Dynasty forbids the sea, but there is still rubber to pass on.

After choosing rubber at dusk, he immediately had an idea: Zheng He had returned from his second trip to the West, and he would prepare to go to the West for the third time this year, so that Zheng He could bring back a large amount of rubber.

After thinking about it again, in the future, the route will be laid out across the country, and what Zheng He brought back will definitely not be enough.

We have to solve this problem at the root.

Two plans: First, this time back to Yingtian, no matter what, even if it violates the interests of all officials, it is necessary to let the Ming Dynasty reopen the sea, so that it can be used by foreign China.

Second, the introduction of rubber trees to fundamentally solve the problem.

The introduction of rubber trees can not only provide a variety of materials, but also provide progress for the railroad, and at the same time provide new industries and employment opportunities for the people in the Ming Dynasty.

Well, this thing can be considered to be implemented at the same time on the Cochin side.

Let Cochin be planted in large quantities, so that the people of Cochin can be appeased, as for the people of the Ming Dynasty, honestly enjoy the benefits of industrial change is to be an "American" in advance.

Thinking of this dusk, I had an idea, and explained to the person in charge of the hydraulic R&D workshop to set up a transmission line R&D department, go to the market to buy rubber at any cost, and experiment how to turn rubber into a pipeline design for wrapping lines.

Then, Dusk found Shen Xili again.

Great progress has been made in the establishment of workshops, but the development of industry is far from being driven by a few workshops, and other industries are needed, the most important of which are the oil and coal industries.

This must be on the agenda.

The oil industry for Daming, exploitation is a problem, the current solution is to buy from abroad, this is a long-term problem, the need for oil tankers, and oil tankers need huge power equipment, Daming does not have the current technology, need to wait for the engine and steelmaking industry to continue to progress, but can take precautions, first use the Ming leading merchant ships in the world to buy barrels of oil back to do industrial research and development.

The second is coal, and it is necessary to increase the use of coal.

In the end, Dusk took out a design of a railroad carriage that he had drawn on the grassland, handed it to Shen Xili, and asked him to set up a department, according to this plan, carefully study and improve it, and then put it into production.

This railcar is not difficult.

In fact, it is an upgraded version of the carriage, mainly in terms of bearings, the steel industry needs to profess itself, but fortunately, the steel used in the ball mill is superhard steel, which can be used for bearings.

It is necessary to put this product into production in about half a year at most.

Shen Xili was amazed.

Of course, Shen Xili's shock not only came from the railroad, but more importantly, he followed Dusk these days, watching the vigorous development of these workshops, he saw a new world.

And then there was a feeling.

Crazy.

It's crazy.

What he did at dusk looked like a madman to others, and the industries he did seemed like crazy.
