Like the Royal Academy of Engineering and the Ordnance Institute, the Daming Ship Administration often leads to frequent fires due to the accumulation and use of large amounts of flammable materials. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

Therefore, the building of the Daming Shipbuilding Bureau, like several natural science research institutions in the capital, is no longer a wooden structure, but a building with the latest concrete wall structure.

This kind of building is not expensive in the current era, so it has not been fully popularized, so it has not challenged the traditional Chinese wooden structure building, of course, the artistry and beauty of the traditional wooden structure building, and the concrete building can not be replaced now.

Moreover, at this time, the Daming Shipbuilding Bureau, like the steel smelting base attached to the ordnance, was also criticized by the local military and civilians, because looking at the black smoke billowing in the sky, he knew that this was a heavily polluting enterprise.

The county magistrate here even sued Zhu Youxiao to impeach Mao Yuanyi, the person in charge of the Daming Ship Administration, for polluting the holy veins, poisoning the fertile fields, and aggravating the people's diseases!

Zhu Youxiao did not blame this county order, and even praised this county order in front of the cabinet, and was the first Ming official to recognize the problem of environmental pollution, and his foresight seems to be hundreds of years ahead of the people of the world today.

Moreover, Zhu Youxiao also directly promoted the county order to be the governor of the Northern Zhili Imperial History, and was fully responsible for the relocation of residents near the major heavy industry bases in the capital of the Ming Dynasty.

There is no way, to solve the damage to the natural environment brought about by the development process, even in the 21st century is a difficult problem, not to mention the current Ming Dynasty, under the influence of limited capital costs, technical strength and national consciousness and other comprehensive factors, in order to prevent the local people from paying the price of their lives because of these heavy industry pollution, Zhu Youxiao can only let them move out of their homeland, which is the only effective way now.

Under the black chimneys were rows of factories and docks, and the Haihe River near the docks was already dark, as if someone had poured ink into it.

But it is precisely in this filthy black Haihe River that you can hear the whistle that can only be heard hundreds of years later, and even a steamship that has begun to take shape can be seen heading towards the mouth of the Haihe River.

This is the second steam-powered ship of the Ming Dynasty to be launched into service, and its size, draft and even speed are more powerful than the "Zheng He", of course, it still has not broken through the shackles of truly realizing all ironclad.

Xu Guangqi, a scholar of Wenyuan Pavilion, and Yang Sichang, the left attendant of the military department, were standing on the deck of this steam-powered ship at this time, and it was the first time for them to come into contact with this kind of ship that did not rely on manpower to paddle, and they naturally felt a lot of emotion in their hearts.

Especially Yang Sichang, the left attendant of the Ministry of War, he is different from Xu Guangqi, and he is not as involved in natural science as Xu Guangqi, a pioneer of Western learning, so now he is like Grandma Liu who entered the Grand View Garden and kept touching here to see where it was, and even asked Mao Yuanyi on the side for advice: "Zhisheng (Mao Yuanyi's word Zhisheng), what does this ship rely on, why can he run away by himself, and the speed is still very fast, I see that someone is burning coal in it, is it possible that the flame of burning coal can make this ship not move." ”

Mao Yuanyi couldn't help but sneer, and didn't dare to make too much fun of this military officer who didn't know anything about natural science, so he couldn't hold back his smile and explained: "Yang Shilang, this is not as simple as burning coal, to be precise, he transferred the heat energy generated by the combustion of coal to the water, so that the water was converted into mechanical energy in the form of water vapor, that is, the bearing was driven in the cylinder, and then the propeller below rotated through the bearing, but the loss caused by this process was very large, basically burning hundreds of catties of coal, It was only a short distance for our ship to travel, so the ship was built not only to hold more guns, but also to hold more coal. ”

"Well, in that case, why can't you find a way to convert all the heat energy after the coal is burned into the mechanical energy you are talking about, so that you can make the ship faster", although Yang Sichang doesn't know much about this, but he is not stupid, and he can roughly understand what Mao Yuanyi said, and even consistently draw inferences.

Xu Guangqi and Mao Yuanyi smiled secretly, they both studied a lot of natural science theory knowledge at the Royal Academy of Sciences, and it was already a fact that they had to admit that the theory of energy conservation could not be transmitted 100%, because they still did experiments under Zhu Youxiao's opposition but still failed, so they didn't know what to say when they heard Yang Sichang, a rookie, mention this.

But he couldn't be cold, Xu Guangqi had to say on the side: "Yang Shilang, that's right, but the heat energy generated when coal burns is not only transmitted to the water, but also to you and me, think about it, when you boil water on the stove, when your water boils, do you yourself feel warm, this can, according to Your Majesty's words, it is generated when the electrons move, what electrons, I don't know, this is what Your Majesty and his heavenly books say." ”

Yang Sichang wanted to ask again, but seeing that Xu Guangqi and Mao Yuanyi had already turned their heads, he didn't want to ask again, so he secretly said that he had to go back and go to the Royal Academy of Sciences to study hard, and he didn't know anything about what Mao Yuanyi said about hydrogen, helium, lithium, beryllium, boron and thermodynamics along the way, and he didn't understand it at all.

But this time he came to inspect the North Sea Fleet, not to see the Daming Shipbuilding Bureau, so he didn't ask any more questions, after all, the main person responsible for inspecting the Daming Shipbuilding Bureau was Xu Guangqi, and Xu Guangqi could understand Mao Yuanyi's heavenly things.

Yang Sichang did not have the awareness of attaching importance to marine strategy before, but since participating in the military aircraft by Zhu Youxiao's side, he gradually understood that this is the real lifeline of the Ming Dynasty, it can be said that although there are tigers and wolves in the north, but they are only fierce on the surface, and their strength is only a matter of one or two years, and on the ocean, the rising Francophone and the red ghost are the future disasters of the Ming Dynasty and even the entire Han people.

For this reason, Yang Sichang himself has made up for a few months of marine knowledge, and this time he came to the North Sea Fleet with a posture of learning and familiarity, so his attitude seemed very humble and sincere, and the officers of the North Sea Fleet such as Qin Botong and Heiwa did not have too strong dislike for him.

After Yang Sichang and Xu Guangqi inspected the Daming Ship Administration Bureau and the expanded Beihai Fleet in accordance with Zhu Youxiao's instructions, and returned to the capital with Li Mingrui, a cabinet scholar, Zhu Youxiao began to prepare for the reorganization of the Beihai Fleet.

According to Zhu Youxiao's meaning, the Ming court will no longer care about his Zheng pirates, and directly establish the Ming Imperial Guard, and the fleet will be directly expanded into three fleets, namely the North Sea Fleet, the East China Sea Fleet, and the South China Sea Fleet.

After recovering from his injuries, Gu San Mazi was directly appointed as the chief officer of the South China Sea Fleet, and his first task was to take his fleet directly south, and pass through the control area of the Zheng pirates to reach the Pearl River region, and assist Shang Zhouzuo, the governor of Liangguang, to re-manage Macao.

According to Zhu Youxiao's meaning, Macao cannot be allowed to become a free land of Western countries in such a blur.
