Chapter 867

"Mr. Brandon, this is the steam locomotive of Chongqing. It's so great. If only we could build such a railway in Holland? "

in the roar of steam locomotives, a Dutch businessman said with envy.

Brandon's eyes are shining with a different light. In the past two years, the trade between Holland and Dayu has been increasing, and both sides have some trust in each other.

Now he came to Dayu with the mission of Parliament.

"There will be some in the future, but before that, we need to maintain a good relationship with Dayu." Brandon said that the foreign trade between the Netherlands and Chongqing has been the envy of European countries.

In addition to them, there are other European countries that want to establish exchanges with Dayu, just because these countries do not have a strong navy, they can only look at the ocean and sigh.

However, it is cheaper for them. Some aristocrats are trying to buy goods from Dayu through Holland.

"It's too late today. Tomorrow morning we'll ask to see the emperor of the state of Dayu. You should prepare some documents and strive for more cooperation this time." Brandon's eyes had been on the steam engine.

Other businessmen nodded. From Dayu to Holland, it's as short as four or five months, and as long as half a year. It's not easy to come here. They can only cherish every opportunity.

While the party was marveling at the steam locomotive of Dayu state, Xiao Ming was meeting members of the research laboratory in the imperial library.

The members of this research room are made up of six people, and the person in charge is Gao Qian.

"You designed the water supply system for the city? "Sitting on the chair, Xiao Ming turned and looked at the nervous six.

With the attention of Qingzhou government to science and technology, research laboratories of large and small are blooming everywhere in Qingzhou University, and the patent office receives all kinds of patents every day.

In the past six or seven years, the talents of Bowen college began to give back their knowledge to Dayu.

Although Lin Wentao is a genius, his successors are constantly emerging. They study things different from Lin Wentao and prove their value.

"Yes, the emperor, the people from Qingzhou City to the royal family are using well water and river water, which is very inconvenient, and it can't meet the supply of restaurants. After designing the water supply system, many businessmen are willing to invest in the construction, but they think that the water can't be given to the businessmen." Gao Qian said.

Xiao Ming nodded. Dayu has made great progress in military industry in recent years, but there are still many shortcomings in terms of clothing, food, housing and transportation. Now, with the improvement of industrial capacity, it is time to improve the schedule of tap water.

"Well, you're right. In that case, I'll give you an imperial edict to set up dayuguo water supply company. The six of you are responsible for setting up the water supply system for Qingzhou." In modern times, used to tap water, he is looking forward to the tap water system.

In history, after the 16th century, the urban water supply in Europe had a great development. London first used pumps to pump water. Cast iron pipes began to be used in the 17th and 18th centuries. In the early 19th century, sedimentation tanks and sand filters were the first water treatment facilities in Britain. From the end of the 19th century to the beginning of the 20th century, disinfection measures for urban water supply appeared one after another in Europe.

In China, the first water supply company was set up in the late Qing Dynasty, but the purpose was to provide fire fighting water for Yuanmingyuan.

For Xiao Ming, now he does not need to develop tap water from scratch, but is ready to skip the previous stage and directly let the tap water enter the sedimentation tank and sand filter.

But in terms of disinfection, he can't afford to use chlorine, because the emergence of electricity makes it possible to produce chlorine on a large scale.

Gao Qian and others were overjoyed. In this way, like Lin Wenyao and Lu Tong, they successfully changed from ordinary students to members of the official company of Dayu state.

"Thank you, Emperor." Gao Qian and others said in unison.

Xiao Ming nodded. He looked at the structural drawing of the reciprocating pump and said, "this pump is shooting well. I'll give it to the machinery factory and let them produce it for you."

The structure of the reciprocating pump is similar to that of the steam engine. It is composed of a cylindrical cylinder, cylinder plug and cast iron water pipe. The power is provided by the steam engine.

Because the reciprocating motion of the steam engine is tangent to the principle of the water pump, it moves back and forth to make the air in the cylinder tend to be vacuum, so that the water is sucked in and then flows out of the water pipe.

So when Xiao Ming saw this design, he was very satisfied, because this reciprocating pump can be used as a large-scale machine to extract river water.

"If so, we will build the water tower first. After all, according to the knowledge of the grassroots, the water supply pipe was reserved when the drainage system was first built in Qingzhou City. Therefore, the emperor is really forward-looking. "Gao Qian does not forget to flatter.

Xiao Ming smiles. The construction of Qingzhou has not only reserved the space for water supply, but also reserved the space for power construction. He has a clear understanding of the development of science and technology. Naturally, he will not do the stupid thing of demolishing, building and demolishing.

"OK, that's it. As for the cost of construction, go to the cabinet for approval." Xiao Ming said.

Gao Qian thanks again, and then he leaves with his members.

Qian Dafu then called out: "next."After a while, three people came to the imperial library. Like Gao Qian, they were all from the research room.

Now, in order to speed up the application of various scientific and technological items in the state of Dayu, Xiao Ming is honored as a guest of honor to all kinds of research laboratories.

However, this is not his initiative, and it is also true in Europe in this era. Both the royal family and the aristocracy are willing to witness all kinds of scientific and technological inventions.

"The emperor, the grass people have brought the plan of biogas street lamp. I hope the emperor has a look." The young man in Qingzhou college uniform presented a drawing to Xiao Ming.

"Today, I have gained a lot. One is tap water, and the other is biogas street lamp. The biogas digester outside Qingzhou City can provide biogas. It seems that you have wasted your mind." Xiao Ming said with emotion.

The young leader said: "originally, we studied the gas street lamp, but getting gas is far less simple than getting methane, so we designed the methane street lamp instead, but the principle is similar. "

" yes, now Qingzhou is becoming more and more prosperous, so we should add some bright colors to the night. " He said to the youth, "I've approved the project. I've approved the money. You are responsible for supervising the construction."

Hearing that, young man was both happy and disappointed. Obviously, his design was not as important as Gao Qian's. However, although he could not enter the royal company like Gao Qian, he could still earn some money for further research.

After finishing his mood, the other two thank Xiao Ming.

Noting the youth's expression, he said, "don't be discouraged. In my opinion, your research direction is right. Both biogas and gas are very important energy sources. Maybe you can further study them. In the future, these things will not be worse than tap water and electricity."
