In history, when steam engines were built, they also experienced a process of slow reduction. The first application of steam engines was not the sea, but the land.
If the Han empire made steam engines, they would be the first choice for ships.
reason? The huge volume of the first generation steam engine is inevitable. If you want to apply it to the train, the locomotive will be very large.
How wide the train is, how wide the track must be. It is impossible to build hundreds, thousands, or even thousands of miles of tracks.
What about waiting for the steam engine to be reduced and creating those wide tracks? The final result will be how wide the track is and how wide the train is. It is impossible to abandon those wide tracks because the train width becomes smaller.
Even for a powerful country, needless to say, if the track is more than ten thousand miles, even if it is only hundreds of miles long, the cost of building the track will not be too low, so we can't give up.
The ship has no trouble of abandonment. As long as it can be installed, there is the replacement of steam engines with different horsepower. The moving project is nothing more than small-scale reconstruction.
"Big man has a new five-year plan." Tian Shuo was asked by Huan Wen about the output of pig iron. He didn't say the current data, but talked about the future: "the boiler has been updating and upgrading. It can be predicted that in the 19th year of Yuanshuo, the output of pig iron will exceed one million tons, but it will directly reach 2.5 million tons. Even steel is confident to reach 200000 tons."
Tian Shuo said it with ease, and the people who heard it were also relaxed. They really didn't know what that output meant.
Only Liu Yan has full pride and pride.
First of all, regardless of the quality of the metal, if the pig iron output could exceed the scale of one million tons by the year of Yuan Shuo, it would directly reach the level of the great powers in the 19th century.
Of course, it's just the bottom among the great powers.
To be clear, not counting pig iron, just steel, the steel output in the 13th year of Yuanshuo was directly close to that of Japan, the most powerful country in Asia in the 19th century.
If, as Tian Shuo predicted, Yuanshuo reached an annual steel output of 200000 tons in 19, it would be equivalent to exceeding the national steel output of the Soviet Union in 1920.
This is an amazing achievement. You should know that even in China in 1920, the national annual pig iron output will be 2.0204 million tons.
The Han Empire directly spanned more than 1500 years and directly reached the production capacity at that time.
Such capacity is naturally not without cost. The unnecessary loss of iron ore, coupled with huge personnel losses, has supported the current capacity.
"So even without castration, just mining will soon consume the slaves." Tian Shuo did not want to antagonize ran min, but to tell the truth: "the number of slaves consumed by the big man in the mine every year has never been less than 200000. At most, it even exceeded 350000."
Ran min's response was to roll his eyes.
If the technical level is not reached, there will be unnecessary loss in smelting metal, which is a necessity that the ore can not be used to the extreme.
Simply put, if the temperature is not enough, there will be more impurities in the metal.
In addition to other aspects, such as the inability to extremely crush the ore, there must be no released metal when refining.
Those wastes were acceptable to the Han Empire.
The Han Empire has now slowed down the mining of local ores. Similarly, the priority of resources is to mine outside the mainland, with the result that the industrial base is also outside the mainland.
At present, there are four largest smelting bases in the Han Empire, one in the grassland, the second in Jiaozhi, the third in Luzon and the fourth in the Japanese islands.
The smelting base on the grassland is in the southwest of modern Ulaanbaatar, where iron ore was explored in the eighth year of Yuanshuo.
After exploration, it was found that the iron ore there was not only easy to mine, but also the mining area was surprisingly large, reaching about 20000 mu.
Jiaozhi's smelting base is in rinan county (Hejing), which is built next to the iron mine, but it is not simply used to smelt pig iron. In fact, the largest output is copper mine.
There are two iron mines and three copper mines in rinan County, and the copper mines are accompanied by gold and silver mines.
Jiuzhen county was found to have an iron mine and two copper mines, but there is a very precious anthracite mineral.
Jiaozhi county has four iron mines and three copper mines, as well as Asia's largest anthracite mine. The anthracite in this place is still open-air. There is no need to dig deeply at all. You only need to be a porter.
It can be said that Luzon is almost an island piled up with metal. According to the relevant documents of the Ministry of industry, only 13 years before Yuanshuo, the explored iron ore reserves exceeded 10000 tons, mainly concentrated in the middle of Luzon Island.
Ten thousand tons of iron ore reserves have been explored in only one island. Will there be more gains in exploring other islands? The answer is continuous harvest. The iron ore reserves there are definitely more than 30000 tons. Some are easy to dig, and some are very difficult to dig.
Luzon islands not only has iron ore resources, but also has more than 10 million tons of copper ore reserves in the 13th year of Yuanshuo alone.
A waiter from the Ministry of industry made a bold guess. He thought that the copper reserves in Luzon islands should reach 50 million tons.
In addition to extremely rich iron and copper mines, gold and silver mines have been found in the Luzon islands.
Those minerals have one thing in common, that is, there is no shortage of open-pit minerals, especially the most open-pit gold mines.
The smelting base of the Japanese islands is not used to smelt copper and iron, but mainly to smelt gold and silver.
In the early days, the Han people returned home with raw ore for smelting. Later, they really couldn't stand that efficiency. The Japanese islands became the first place for the Han people to build smelting related facilities outside their own land.
With the Japanese Archipelago as the beginning, the following three places began to be built.
If mineral resources are discovered, as long as the reserves are confirmed to be sufficient, it is far more correct to start the construction of relevant industrial facilities than to transport the raw ore all the way... Or all the way back to China.
As for whether it is appropriate to build industrial bases outside the mainland, it must be said that it is actually very appropriate, not only to increase production efficiency, but also to reduce local pollution.
"We must be cautious in the planning of heavy industry." Liu Yan felt the prestige and looked at the constantly broken water surface: "if you can get abroad, don't put it at home."
The iron ship has sailed on the river. After the sails are fully opened, the wind is not small, but it really can't run fast.
I don't know how many people crowded around the nearby banks. They came either to watch the trial voyage of the iron ship or to pay tribute to Tianrong, or they were too far away. Even if they could see the son of heaven, they looked like a very vague figure. Only this made them very excited.
"What your majesty said is that the waste water from heavy industry is discharged, and there is no grass at all." Tian Shuo personally inspected Jiaozhi: "I went to a place. I didn't know until I asked. It turned out that there were green mountains and green water. But in less than a year, the water became a smelly ditch, and the surrounding plants were shrouded by waste gas day and night."
Smelting, there must be exhaust. You can imagine how a chimney spits fog.
The wastewater from smelting is generally produced by the washing process, and washing is also a process that produces the most pollutants.
"Therefore, not only heavy industry, such as paper mills, should not be placed in China." Sang Yu was not just trying to make fun: "when I went back to my hometown to worship my ancestors, I found that the clear stream turned into mud. I went to have a look and found that it was not dry and turned into mud, but that the stream 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. In less than a month, the originally clear stream became extremely unbearable, let alone swimming. When the weather is hot enough, you can run on the hardened paper residue.
Liu Yan grew up in an age when green mountains and green waters were constantly polluted. He saw all the beauties destroyed one by one. Only a small carton factory abandoned a stream and polluted nearly 20 miles of water.
Whether the carton factory has made a lot of money is not the key. It is the end of the stream. At the same time, the surrounding farmland is difficult to carry out farming because of lack of water source, and the abandoned farmland is definitely more than 3000 mu.
The farmland can't be cultivated. The report is just that the relevant departments came to carry out the so-called investigation, and I don't know what the investigation method is. The carton factory didn't even shut down. Those who came to investigate not only came to eat, drink, play and whore, but also had a lot of money when they went back.
The original water town is gone forever. The carton factory has always existed, and then the stone factories are opened one after another. There are not only the color of paper residue in the stream, but also the white of the waste water discharged by the stone factory. When the two colors are mixed together, it seems that the way is like flowing excrement.
"The environment makes concessions for the economy, ha ha..." Liu Yan looked at Tian Shuo: "if one day let me know about it..."
The environment of thousands of years can be completely destroyed in a year, but it may not be able to recover in decades.
Before Liu Yan crossed, the paper mill had closed down, and the stone factory had closed down successively. Thirteen years later, the stream was still flowing with shit.
What he experienced personally is only one, but it is a nightmare that can never be erased. Liu Yan has not seen cancer village on various news.
Those who have made money, even if the factory closes down, have already made the money they should have made.
Because a few people make money, but more people suffer. After suffering, there will be no compensation, that is, the so-called environment makes concessions for the economy!
I also took the iron boat. If the guy at my feet was not an iron boat, it would be no different from taking other boats.
The patrol team left Jiangdu and crossed the river to the south bank, but it did not enter Jiankang as expected. It turned to Danyang County in the southwest of Jiankang.
Danyang county is not the destination of the patrol team. The destination is Jiangnan Shipyard (Hangzhou Bay) in Kuaiji county. During this period, we will also patrol around the area (Taihu Lake).
"The area is the concentration of handicraft industry." Xie an didn't know so much because he was born in the south of the Yangtze River. As the Minister of household, he was able to check the tax collection of various places: "the tax amount around the area accounts for 3.7% of the Han."
Although the percentage is only 3.7, it depends on how big the territory of the Han Empire is, and it is not just the local people who need to pay taxes.
"Jingkou is so close to Youqu that 3.7 is not much." Huan Wen curled his lips and said, "why don't you say the tax outside the pass."
Xie an said helplessly, "it's different. Outside the pass is the concentration of textile industry."
"So it's not that the grassland is useless, but the fools in front didn't find it useful." Ran Min said happily, "only wool provides the textile industry, which makes it difficult for the grassland to separate."
Before the dynasty elite is not a fool to say, but ran min is right. In the past, he easily gave up the grassland because there was only expenditure but no harvest.
Now that wool is used in the textile industry, who dares to give up the grassland, regardless of the reaction of the country, the group of people who benefit only from wool textile can't let go of those who dare to say that.
Liu Yan asked, "what are the main commodities in Jingkou's foreign trade?"
Yu Yu immediately replied, "silk, porcelain and tea."
As Jiankang Ling, Yu Fu also followed the patrol team because Liu Yan was bound to ask about Jingkou.
Silk is now the best-selling fist product, but this silk is more than one kind, and Shu Brocade is included.
During Wang Meng's mission to various countries, Shu Brocade was truly famous in the world.
Waiguoren couldn't distinguish the types of silk so carefully. They only knew that the Romans were crazy about Shu Brocade because the Romans were willing to pay a high price. No matter which country businessmen came to the Han Empire, the first thing they wanted to buy was Shu brocade.
"Porcelain?" Liu Yan asked curiously, "what do they call porcelain?"
Yu Heng was a little confused. He thought a lot in advance, but he didn't expect Liu Yan to ask this.
"Don't you read porcelain?" Yu Yi must extricate himself from the siege for his nephew: "what should I read?"
"As far as I know, Frank called calling porcelain 'kick that'?" Huan Wen joked, "what's the ghost name? LV Shangshu should send someone to scold!"
Lu Yi usually said, "what Huan Shangshu said is very true. Those savages should speak human words well."
As the overlord of Europe, Rome used to call the Han Empire cyris. After they really recognized the strength of the Chu Han Empire, they may continue to use the name cyris in private, but in public, they definitely use the name of the Han Empire.
A few big guys make fun, nothing more than showing an attitude of caring for the younger generation. Each of them has his own nephew. If he can get rid of the encirclement, there is no risk. Why not?
"There are really people called China." Liu Yan wondered, "do Franks belong to the Germanic family?"
It's strange. Is China the Germanic who shouted first? Shouldn't it be English pronunciation?
What Liu Yan doesn't know is that Westerners come into contact with Qidan and porcelain. No matter which nationality they are, they all use the pronunciation of China.
