The Rise of the European Emperor

For people of this age, the rickshaw is undoubtedly a sophisticated machine. And in this era, those who are best at tinkering with precision machines are those watchmakers.

Da Vinci learned a few hands from these watchmakers at the beginning, and in the original history, he created a mechanical lion, driven by clockwork. And the technical content of the human tricycle will definitely not be higher than that of the robot lion.

However, Da Vinci now has a heavier task, leading two groups of students to develop diesel engines and steam engines, and teaching a group of chemical engineering students.

Therefore, although Da Vinci was the most suitable, Marin still did not ask him to develop a human-powered tricycle. After all, people are too busy to touch the ground. If you go to him to work on the rickshaw again, you will definitely be exhausted...

Moreover, Marin was familiar with human-powered tricycles and bicycles in his previous life. After all, it's all in the house. Before the rise of electric vehicles, the Marin family basically used bicycles for travel. When going out to transport some things, in addition to using walking tractors for large quantities, a small amount of goods are basically used by manpower tricycles.

Because I have been using bicycles and tricycles for a long time, there have been many problems in the middle, and I have repaired them many times. Therefore, Marin can think of the structure of bicycles and human tricycles with his eyes closed.

Therefore, he doesn't need Da Vinci's big boss, as long as an ordinary watchmaker with good craftsmanship can make a rickshaw under his guidance. As for the bicycle that he is more familiar with, because it is of great significance without a human-powered tricycle, Marin plans to let it go first.

Moreover, when the human-powered tricycle is produced, the bicycle is just a simple modification without any difficulty.

The only problem is probably the supply of oil required by the chain and the supply of rubber tires. After all, when manpower tricycles become a popular means of transportation, the oil and rubber tires required for the chain will definitely consume a lot.

Although it hasn't been done yet, Marin has never worried about whether the rubber tire can be done. He is only worried about the consumption of rubber tires. After all, in later generations, it is common for bicycles to change tires, and the consumption of rubber tires is very large.

However, today's natural rubber production is limited. Although the new natural rubber has been planted, it will take six or seven years to tap the rubber... Therefore, Marin suddenly felt that the planting of natural rubber needed to be expanded! Otherwise, once the human-powered tricycle is produced, the consumption will be astonishing...

In addition, the output of chain oil should also be raised. Therefore, the pace of oil development should also be accelerated. After all, motor oil is also extracted from the high-boiling residue left after gasoline, diesel, and kerosene are extracted from petroleum.

also,

The research and development of wear-resistant tire technology also needs to be put on the agenda. Marin remembers that later generations of car tires are all added with carbon black, which can increase the wear resistance of tires by ten times. Originally, white rubber tires without carbon black had a lifespan of only 8,000 kilometers. With the incorporation of carbon black, the lifetime is increased tenfold.

Therefore, Marin also needs to order his subordinates to study how to mix carbon black powder into white tire casings. Moreover, the amount added needs to be controlled. This requires many attempts. But after knowing the principle, at least you can avoid a lot of detours.

In addition, Marin will take one step and directly adopt the radial tires that are popular in later generations. In this way, too many detours are avoided. As long as the research on radial tires with carbon black added is successful, and the production of natural rubber is greatly increased, the wheels of vehicles in Beihai will be dominated by rubber tires in the future.

But first, the source of the rubber needs to be plentiful...

Although Marin knew about synthetic rubber, he didn't understand chemistry or how to synthesize rubber. Therefore, he can only choose to plant more natural rubber.

In later generations, the largest natural rubber producing areas are in Malaysia and Indonesia in Southeast Asia. But Marin knows that the reason why natural rubber is produced in Southeast Asia instead of America is because in the nineteenth century when the use of natural rubber was discovered, most countries in the Americas became independent, and only Southeast Asia and other places were still European colonies. Therefore, Europeans can only vigorously develop rubber plantations in Southeast Asia, such as Malaysia and Indonesia. In the Americas, there is less promotion.

Therefore, it is not that rubber cannot be planted in the Caribbean, but that when rubber was promoted, many countries in the Caribbean had already become independent. Or, because of the small size of the island and the lack of labor force, rubber plantation has not been promoted.

After all, planting natural rubber and tapping rubber are labor-intensive industries that require a lot of labor. At that time, in Southeast Asia, there were many Malays, and there were also hardworking Chinese immigrants available, so a large-scale rubber plantation industry was developed.

Today, although Marin has no hardworking Chinese workers available. However, it is still possible to plunder tens of thousands of laborers from the island of Haiti with a population of one million to grow natural rubber. It seems that Haiti in later generations also produced natural rubber.

But Marin is very afraid of syphilis on Haiti, so he doesn't plan to plant rubber on Haiti, but plans to take all Taino people who are not infected with syphilis away from Haiti. Then, leave the remaining syphilitic patients on the island to fend for themselves. When all these syphilis patients are dead, Marin will have to wait a few years before bringing people back to develop Haiti.

For this reason, Marin has issued an isolation order to isolate all people infected with syphilis, whether they are Europeans or indigenous people. Islands with a large number of syphilis patients will also become temporarily isolated areas.

In fact, apart from the prevalence of Taino syphilis in Haiti, there are also many Taino tribes in the eastern part of Cuba with syphilis patients.

Therefore, while Marin ordered the development of the Guantanamo area, he also planned to send troops to clean up the Taino people in the east of Cuba Island in the future. Once a syphilis carrier is found, they will be isolated and left to fend for themselves. The ultimate goal is to eliminate all sources of syphilis.

Syphilis is too contagious. Although Marin knows that penicillin can treat syphilis, he believes that it is better to eliminate the source of syphilis, which is more worry-free and trouble-free.

The source of syphilis is also in Haiti and several nearby islands. Marin intends to take advantage of the opportunity of conquering the island of Haiti and send four or five thousand soldiers and horses, plus two thousand father-in-laws, to conduct inspections on the Caribbean islands in turn to isolate all syphilis patients. And use lime powder, etc., to thoroughly kill the virus, in order to eliminate the source of this vicious disease.

At the same time, when the syphilis patients were checked, those Indians who were not infected with syphilis would also be taken away to help Marin grow natural rubber.

In this way, it can be regarded as killing two birds with one stone. It not only eliminates the source of syphilis, but also brings a lot of labor to help Marin grow natural rubber. When rubber tires become popular in the future, there will be no problem of supply difficulties.

Of course, in order to prevent the aborigines from dying of such a disease as smallpox, Marin will first let them all be vaccinated, so that they will not be afraid of smallpox in the future.

In addition, Marin intends to implement a strict quarantine system and conduct strict health checks on Europeans going to America to prevent Europeans suffering from serious diseases from bringing infectious diseases to America and triggering the extinction of local people. In this way, he will not be short of labor.

In order to prevent the aborigines from having a sense of ownership in their hometown and confronting the colonial authorities, Marin will find a way to take the aborigines away from their hometown and let them come to other places. In this way, it is not easy for them to do things if they are not familiar with the place. For example, the Taino people in Haiti, after being brought to Cuba, will become very honest for a long time. And after they are familiar with the local area, if they want to be dishonest, they have no chance. Because Marin won't give them a chance... Plus, the North Sea country doesn't treat the aborigines badly, as long as they can make do with it, no one wants to go to death...
