In history, the steam engine was manufactured, and it will go through a process of shrinking. The first application to the steam engine was not the ocean, but the land.

If the Han Empire made a steam engine, it would be the first choice for use in ships.

reason? It is inevitable that the first generation of steam engines will be bulky. If they want to be applied to trains, then the locomotives will be very large.

As wide as the train is, the track must be as wide as it is. It is impossible to build a track that spans hundreds, thousands, or even thousands of miles.

Waiting for the steam engine to be downsized, and what to do to create those wide tracks? The final result will be how wide the track is, the width of the train will remain as wide, and it is impossible to discard those wide tracks because the width of the train becomes smaller.

Even if it is a powerful country, not to mention a track of more than 10,000 miles, even if it is only a few hundred miles in length, the cost of building a track will not be so low, so you can't just give up and give up.

Ships do not have the trouble of discarding them. As long as they can be installed, they can be replaced with steam engines of different horsepower. The moving projects are nothing more than small-scale reconstructions.

"Dahan has a new five-year plan." Tian Shuo was asked by Huan Wen about the production of pig iron. He did not mention the current data, but talked about the future: "The boiler has been updated and it can be expected that in the 19th year of Yuanshuo, the production of pig iron will break through. One million tons, but it will directly reach 2.5 million tons of output. Even steel is confident to reach 200,000 tons."

Tian Shuo spoke lightly, and the people who heard it were also light-hearted. They really didn't know what the output meant.

Only Liu Yan has full pride and pride.

Regardless of the quality of the metal, if the output of pig iron in Yuanshuo in the 19th year can exceed one million tons, it will directly reach the level of the great powers in the 19th century.

Of course, it's just the bottom of the big powers.

To be really clear, not counting pig iron, just considering steel, Yuanshuo's steel output in the 13th year directly approached the output of Japan, the strongest Asian country in the nineteenth century.

If, as Tian Shuo expected, Yuan Shuo's annual steel output reached 200,000 tons in 19 years, which would have exceeded the national steel output of the Soviet Union in 1920.

This is an amazing achievement. Even in China in 1920, the country’s annual pig iron output was only 2.02 million tons.

The Han Empire directly spanned more than 1,500 years and directly reached the production capacity at that time.

Such production capacity is naturally not without cost. The unnecessary loss of iron ore, coupled with the huge loss of personnel, supports the current production capacity.

"So, even if we don't castrate, just mining will quickly consume the slaves." Tian Shuo didn't want to chase Ranmin, but told the truth: "The number of slaves consumed by the big man in the mines has never been low. It’s over 200,000. At its peak, it’s even more than 350,000."

Ran Min's response was to roll his eyes.

If the technical level is not reached, the smelted metal will definitely suffer unnecessary loss, which is a necessity for the ore not to be used to the extreme.

Simply put, if the temperature is not enough, there will definitely be more metal impurities.

In addition to other aspects, such as the inability to extremely crush the ore, there must be no metal released during the refining.

Those wastes are acceptable to the Han Empire.

The Han Empire has now slowed down the mining of local ore. The first choice for the same resources is to mine outside the local area. As a result, the industrial base is also outside the local area.

There are currently four largest smelting bases in the Han Empire, one is located in the grassland, the second is in Jiaozhi, the third is in Luzon, and the fourth is in the Wa Islands.

The smelting base on the grassland is southwest of modern Ulaanbaatar, where iron ore was explored in the eighth year of Yuanshuo.

After exploration, it was discovered that the iron ore there is not only easy to mine, but also the area of ​​the mining area is surprisingly large, reaching about 20,000 mu.

The smelting base of Jiaozhi is in Nichinan (Hajing), which is built next to iron ore, but it is not purely used to smelt pig iron. In fact, the largest output is copper ore.

There are two iron mines and three copper mines in Nichinan County. Copper mines also have associated gold and silver mines.

Jiuzhen County was found to have an iron mine and two copper mines, but there are very precious anthracite coal mines.

There are four iron mines and three copper mines in Cochin County, as well as the largest anthracite coal mine in Asia. The anthracite in this place is still open, so there is no need to dig deep at all, just as a porter.

Luzon can be said to be almost an island piled up with metal. The relevant documents of the Ministry of Industry record that only 13 years before Yuanshuo, the iron ore reserves that have been explored exceeded 10,000 tons, mainly concentrated in Central part of Luzon.

Only one island has explored 10,000 tons of iron ore reserves. Will there be more gains from exploring other islands? The answer is that there are continuous harvests. The iron ore reserves over there are definitely more than 30 million tons, but some are easy to dig, and some are very difficult to dig.

The Luzon Islands not only have iron ore resources, but in the 13th year of Yuanshuo alone, the copper ore reserves that have been explored exceeded 10 million tons.

A servant of the Ministry of Industry made a bold guess. He believed that the copper reserves in the Luzon Islands should reach 50 million tons.

In addition to extremely rich iron and copper deposits, the Luzon Islands have also been discovering gold and silver deposits.

Those mines have one thing in common, that is, there is really no shortage of open-pit mines, especially gold mines with the most open-pit mines.

The smelting base on the Wa Islands is not used to smelt copper and iron, but is mainly used to smelt gold and silver.

In the early days, the Han people returned to China with the original ore for smelting. Later, they couldn't stand the efficiency. The Waley Island became the first place where the Han people built smelting-related facilities outside of the mainland.

With the Wa Islands as the beginning, the construction of the following three places began.

Once the mineral resources are discovered, as long as the reserves are confirmed to be sufficient, the construction of related industrial facilities is far more correct than transporting the rough ore back to the country.

As for whether it is appropriate to build an industrial base outside the local area, it must be said that it is actually very appropriate. It is not only to increase production efficiency, but also to reduce local pollution.

"Heavy industry planning must be prudent and careful." Liu Yan felt the prestige and looked at the water that was constantly being broken open: "If you can get it abroad, don't put it in the local area."

The iron ship is already sailing on the river. After the sails are fully opened, the wind is actually not small, but it really doesn't run fast.

I don’t know how many people crowded to watch on both sides of the strait nearby. They were either to watch the trial of the iron ship, or to admire Tianrong, or they were too far away. Even if they were able to see the emperor, they looked like a very vague figure. This alone made them extremely excited.

"Your Majesty is right, the waste water from heavy industry can be described as dead." Tian Shuoyou personally went to Jiaozhi to inspect it: "The minister went to a place, don't ask, I don't know, I know that it is also a green mountain after asking. Green water. But in less than a year, the water turned into a stinky gutter, and the surrounding plants were enveloped by exhaust gas day and night."

Smelting, there must be exhaust, you can imagine how a chimney spit out fog.

Wastewater from smelting is generally produced in the washing process, and washing is also the process that produces the most pollutants.

"So it's not just heavy industry, like paper mills, shouldn't be located in the local area." Sang Yu was not purely for fun: "The minister returned to his hometown to worship the ancestors, and found that the clear stream had turned into mud on the way. I went to take a look and found that It's not that dryness has turned into a quagmire, it's that the stream water has accumulated very exaggerated paper residue!"

Sang Yu's words reminded Liu Yan of his childhood.

When Liu Yan was young, the stream was so clear that he and his friends would be invited to play and swim every summer.

One day, a carton factory started on the edge of the stream. It took less than a month. The original clear stream became extremely unbearable. Let alone swimming, it can run on the hardened paper scraps when the weather is hot enough. .

Liu Yan grew up in an era when the green mountains and green waters were constantly polluted. He saw all the good things being destroyed one by one. Just a small carton factory destroyed a stream and polluted nearly twenty miles of water.

Whether the carton factory has made a fortune is not the key. The stream is over. At the same time, the surrounding farmland is difficult to farm due to lack of water. The abandoned farmland definitely exceeds 3,000 acres.

The farmland cannot be cultivated, and the report is just the relevant department coming over to conduct the so-called investigation. I don’t know what the investigation method is. The carton factory does not even stop work. Those who come to investigate not only eat, drink, and prostitute when they come, they go back. When the time is also bulging.

The original water village is gone forever, and the carton factory has always existed. Then the stone factories opened one after another. The stream water not only has the color of paper residue, but also the white of the waste water discharged from the stone factory. The two colors are mixed together. Going up makes it seem like flowing **** along the way.

"Environment is the economic concession, haha..." Liu Yan looked at Tian Shuo: "If one day you let me know that there is such a thing..."

Thousands of years of the environment can be completely destroyed in a year, but it may not be able to recover after decades.

Before Liu Yan crossed, the paper mill had closed down, and the stone mill had also closed down one after another. Thirteen years later, the stream was still flowing with shit.

What I personally experienced is just that, but it is a nightmare that will never be erased. Liu Yan has not seen Cancer Village in various news.

Those who have made money, even if the factory closes, have already made the money that should have been made.

Because a small number of people make money, but more people suffer. After suffering, there will be no compensation. That is the so-called environment is economic concessions!

I took the iron boat too. If the guy under my feet was an iron boat, it would actually be no different from taking other boats.

The patrol team left Jiangdu and crossed the river to the south bank, but did not enter Jiankang as many had expected, but turned to Danyang County on the southwest side of Jiankang.

Danyang County is not the end of the patrol team. The end point is at the Jiangnan Shipyard (Hangzhou Bay) in Kuaiji County. During the period, it will patrol around Gu District (Taihu Lake).

"Guo District is the center of handicraft industry." Xie An understands not because he was born south of the Yangtze River, but he, as the household minister, can check the tax summaries of various places: "The tax amount around Gu District accounts for a percentage of the big Han. 3.7."

Regardless of the percentage of 3.7, it depends on how large the territory of the Han Empire is, and it is not just the mainland that needs to pay taxes.

"Jingkou is so close to Guqu, 3.7 is not too much." Huan Wen curled his lips and said, "Why don't you talk about the tax amount outside the customs."

Xie An said helplessly: "It's different. Outside the customs is the center of the textile industry."

"So the grassland is not useless, but the idiots in front have no use." Ran Min said happily: "It is only the wool that provides the textile industry, making it difficult to separate the grassland."

The previous dynasty elites did not say whether they were stupid, but Ran Min was right. In the past, he gave up the grassland easily because the grassland only had expenditure but no gain.

Now that wool is used in the textile industry, who dares to say that we will abandon the grassland, regardless of how the country will react, the group of people who benefited only from the wool spinning will definitely not let go of those who dare to say that. .

Liu Yan asked: "What kind of products are Jingkou's foreign trade mainly based on?"

Yu He immediately replied: "Silk, porcelain and tea."

As Jiankangling, Yu He also followed the tour team because Liu Yan would inevitably ask about Jingkou related matters.

Silk is now the best-selling competitive product ~lightnovelpub.net~ But this silk is more than one type, and Shu brocade is included.

When Wang Meng went to various countries as an envoy, Shu Jin really achieved fame in the world.

Crooked nuts can’t divide the types of silk so finely. They only know that the Romans are crazy for the silk brocade, because the Romans are willing to pay big prices. No matter which country merchants came to the Han Empire, they were the first goods they wanted to buy. It's Shu Brocade.

"Porcelain?" Liu Yan asked curiously: "What do they call porcelain?"

Yu He was a little confused. He thought a lot beforehand, but he didn't expect Liu Yan to ask this.

"Don't you read porcelain?" Yu Yi must help his nephew: "What should I read?"

"As far as I know, the Franks call porcelain ‘Kuna’?" Huan Wen said jokingly, "What kind of name is this? Lu Shangshu should send someone to reprimand!"

Lu Yi usually jokingly said: "Huan Shangshu's words are extremely true. Those savages should speak well."

As the overlord of Europa, Rome used to call the Han Empire Seres. After they truly recognized the power of the Han Empire, they may continue to use the name Seres in private, but they definitely use the name of the Han Empire in public.

Several big guys have fun, nothing more than showing an attitude of caring for the juniors. All of them have their own nephews and nephews. They can make a siege, and there is no risk in the siege. Why not?

"It's really called China." Liu Yan wondered: "The Franks belong to the Germanic family, right?"

It's weird, is China the Germans to call first? Shouldn’t it be pronounced in English?

What Liu Yan didn't know was that Westerners came into contact with Khitan and also came into contact with porcelain. Regardless of which ethnic group they belonged to, they all use the pronunciation of China.
