As the effect of the rise of Han in South America spreads, the international situation is increasingly developing on a trajectory different from its original history.
The situation in South American countries continues to be turbulent. Some white families living in South America and the surplus European population have gradually abandoned South America and chosen the United States, Canada, Australia, New Zealand, South Africa and other countries as their immigration destinations.
Affected by this change, the United States, Canada, Australia, New Zealand, and even colonies in Africa such as South Africa and Rhodesia also received more white immigrants than during the same period in history.
The number of white people in the United States, Canada, Australia and other regions has increased. In the competition between various ethnic groups in the world, Western society has become stronger than at the same time in history. Facing the historical changes caused by the rise of the Han Dynasty, Li Mingyuan felt surprised and also experienced a kind of
An urgent sense of urgency.
The closer the time approaches to the twentieth century, the more mature and complex the development of science and technology becomes, and the role Li Mingyuan can play in it becomes smaller and smaller. Therefore, in order to try to reduce the negative impact of the butterfly effect on Han's interests,
The research and development process of some core technologies and weapons must be accelerated and carried out as soon as possible.
“The use of DC transportation consumes a lot of electricity and costs a lot, so it is not suitable for widespread promotion.
Although the American Edison advocated the use of DC and tried various methods to expand the scope of DC power supply, it only partially improved the power supply situation in small and medium-sized cities. As for the power supply in large cities, the DC power station improved by Edison was still unable to do anything.
The future of electric transportation lies in the AC power generation method.
Although the local area lacks high-quality anthracite coal, there is no shortage of ordinary thermal coal resources. Thermal coal reserves in the three states of Jiangdong are abundant and can be used as raw materials for thermal power generation. Moreover, the central and northern areas of the local area are rich in hydropower resources. You can try to use some water flows to
Build large-scale hydropower stations in river basins with rapid water levels and large water level differences to rationally utilize local water resources."
Electric power is the source of future industrial development, and Li Mingyuan has always paid great attention to local development in the electric power field.
"Thermal power, water power and even wind power can generate valuable electrical energy. In 1882, when the first medium-sized hydropower station was built in the local area, due to imperfect technical reserves, it could only use the direct current power generation mode and other reasons, resulting in the Xing'an River Hydropower Station (General Electric Power Station).
Rimeiro River Hydropower Station) has always had problems such as low power generation efficiency and huge consumption in the transportation process.
In recent years, a large number of emerging companies have appeared in cities such as Chang'an, Songjiang, Huaiyang, and Xinjing, and their demand for electricity has become even stronger. Taking the Xing'an Hydropower Station as an example, the generator sets used in the first-generation power station only generate two to three times a unit.
Ten kilowatts, a power station with a total power generation of about 100 kilowatts can only meet the power needs of three to five medium-sized factories, but it cannot undertake the task of supplying power to the entire city."
Compared with the chemical industry, the technical level and control difficulty in the electric power field are higher.
At the same time, Li Mingyuan, who majored in chemical engineering, can give key guidance in many subdivided fields. However, in the field of electric power, it is only directional guidance and does not have as obvious help to electric power researchers as it does in the field of chemical industry.
If AC power is used for remote power supply, the voltage needs to be increased to reduce the power loss in the transmission line, and then a transformer must be used to reduce the voltage before it can be sent to Gongchenghe Enterprises.
The DC transformer originally used in Han Dynasty had a simple structure and was easy to maintain. Of course, the effect was not that ideal.
The AC transformer is relatively complex. The Royal Academy of Sciences began research on AC transformers after the Xing'an Hydropower Station was put into operation in 1882. However, it was not until 1886 that Stanley, an engineer from the American Westinghouse Company, developed an excellent performance transformer.
After the invention of the AC transformer, Han Dynasty developed a localized AC transformer in 1887 by drawing on Stanley's technical experience.
Han is one step behind the Americans in the field of AC transformers.
However, relying on some of the prophetic advantages provided by Li Mingyuan, the Han Dynasty has achieved further achievements in the field of generating units.
Early generators were driven by steam engines. In September 1883, the Royal Academy of Sciences used a newly invented mechanical turbine to replace the steam engine, which was directly connected to the generator. At the same time, the cloud gear and other devices were removed, which solved the problems of unstable operation and serious wear and tear of the generator set.
In May 1886, the power generation efficiency of the new turbine reached 75 kw, and an experimental hydropower station was built on the bank of the Paraná River and was operating well.
For more than two years after 1886, many researchers at the Royal Academy of Sciences tried to experimentally improve the performance of turbines, and in July 1888, they developed a second-generation turbine with a speed of 9,000 rpm and a power generation of 150 kilowatts.
Although a small turbine with a generating power of 150 kilowatts is insignificant compared to the turbines with a power of one million kilowatts in later generations, in the current era, only the United Kingdom, the United States, France, and Germany are the only countries whose technical level can reach similar standards as that of Han.
.
It was the first to take the lead in AC hydropower power stations. Although it was a step behind the Americans due to technical reserve factors, it took the Han Dynasty five or six years to once again make progress in the core field of electric power and regain cooperation with the United States and Germany.
Standing on the same starting line in the electric power field, this means that the stalled power station construction projects will usher in a new explosive period.
While carrying out the construction project of the second generation power station, we are also overcoming the technical difficulties of the third and fourth generation power stations.
Li Mingyuan sat at the top and gave clear goals to the officials of the Electric Power Department of the Ministry of Industry: "Before 1900, complete the research goal of 1,000 kilowatt turbines, and before 1910, increase the power generation capacity of the turbine to 10,000 kilowatts."
According to the research and development progress of Western countries in the field of emerging science and technology, the research and development goals set by Li Mingyuan for officials and relevant researchers of the Royal Academy of Sciences are not fantastic. After all, in the original history, Western countries also completed the goals within a similar time limit.
Technical problems in power generation.
"Your Majesty, the power generation project involves many fields. I request that more scientific researchers be allocated to assist the Electric Power Department of the Ministry of Industry in carrying out its work."
Shen Xian, the director-general of the Ministry of Industry, accepted the task and immediately put forward the conditions.
"You will have priority in selecting top physics majors who have graduated from major local institutions of higher learning. Electricity-related researchers at the Royal Academy of Sciences will also have priority in cooperating with your work."
Li Mingyuan said magnanimously: "You can use these people first, and in two or three months, when the power researchers hired by the government from Western countries arrive in the country, the difficulty of your tasks will be much easier."
"Thank you, Your Majesty."
The Director-General of the Ministry of Industry bowed slightly and then asked cautiously: "There are twelve German electric power researchers in the Royal Academy of Sciences. Are most of the electric power researchers hired this time also Germans?"
"Germans account for about half, and the rest include Austro-Hungarians, French and an American."
Li Mingyuan recalled the list of high-paying hires and said with a smile: "I remembered one person wrongly. Tesla has not been naturalized in the United States. Now, strictly speaking, he should be a Serbian-Austro-Hungarian."
As a man of science and engineering in my last life, it is impossible that I have not heard of Tesla's name.
During the period from the late nineteenth century to the first half of the twentieth century, Tesla could be said to be one of the most accomplished scientists.
Throughout his life, he built the largest AC hydroelectric power station in the United States, and successively invented radio remote control technology,
He has developed far-reaching scientific and technological technologies and obtained about 1,000 patented inventions. However, these did not make him rich. Instead, he often fell into financial constraints.
As early as 1880, the Han Dynasty sent personnel to contact Tesla. However, due to Western public opinion's malicious smear campaign against the Han government and Tesla's own obsession with the development of scientific research and technology, the persuasion action has not made progress.
In 1880, Tesla was still a little-known figure. It was not difficult to forcibly kidnap him to the South American mainland with the methods of the Han Dynasty. But a Tesla who was forcibly kidnapped and unwilling to cooperate,
It cannot help Han's technological research and development, so according to the instructions of the local government, Tesla's persuasion work has been carried out in a gentle way.
In 1888, the long-term deployment against Tesla achieved final success. Under the secret instigation and influence of the Han Dynasty, the relationship between Tesla and his American counterparts came to the edge of rupture.
In February 1888, Edison bribed certain government officials and put Tesla in jail on suspicion of illegal competition.
In April 1888, the Tesla Electric Company was banned. Although Tesla himself was released, he also lost all his assets in the United States.
In October 1888, after being completely disappointed with the despicable behavior of his American colleagues, especially his original employer Edison, Tesla, who was penniless and marginalized, reluctantly agreed to the invitation of the Han Dynasty and agreed to work in South America.
scientific research.
Although the methods are a bit shady, as long as they can complete the tasks assigned by the local government, not to mention just using small tricks secretly, but also more drastic methods, intelligence personnel stationed in the United States will also try them.
