On the fourth day of the second month of the ninth year of Tianwu, on the day of the "Holy Day", Zhu Cihong accepted the congratulations of the ministers in the Fengtian Temple and held a banquet in the palace.

Today is the birthday of Emperor Zhu Cihong of the Ming Dynasty, and as ministers, everyone naturally wants to express it.

Some people gave calligraphy and paintings, some people gave treasures, and some people sent all kinds of strange things, with a note saying a copy.

All in all, it all makes sense!

One of the most surprising was that the Royal Academy of Sciences actually sent a train!

After hearing this, Zhu Cihong didn't even eat, and took the Minister of Civil and Military Affairs to the location of the experimental field of the Royal Academy of Sciences outside the eastern city.

The steam engine is his most important research project, which is related to the future social development of the Ming Dynasty, whether it is for the social and economic development, or for the improvement of military strength, it is a qualitative leap!

In the near future, if the steam engine can be used in social production as soon as possible, it will greatly improve the current production efficiency.

In the recital, Sun Heding, president of the Huangming Academy of Sciences, referred to the train as a steam locomotive, and some officials did not understand, thinking that this thing steamed steamed buns or steamed rice? Need the emperor to be in person?

The Machinery Department of the Huangming Academy of Sciences, which is a very extensive workshop, which houses a large number of tools and semi-finished mechanical appliances, including siphons, crane drinks, light pots, substitute farming, rotation mills, bicycles, etc.

These are mainly used for agricultural production, and they are basically the masterpieces of the old academician Wang Zheng.

Walking inside, everyone heard a commotion.

Zhu Cihong looked for the sound and saw several steam engines running in the distance, each of which was headed by two people to shovel carbon and make a fire, and hot water was placed on the side.

Steam constantly comes out with the up and down movement of the piston, driving the runner to rotate and making a "squeak" sound from time to time.

On two small steam engines, each with two spinning wheels, the spinning wheels are connected to the runners, and they are "gurgling" and turning.

The large steam engine is connected to a deep well, which is also constantly pumping water.

There are also steam engines attached to huge stone mills.

The project of the steam engine, which has been developed by the Royal Academy of Sciences since its establishment, has been under the order of nearly ten years.

The first steam engine had actually been developed in Tianwu for three years, and Zhu Cihong also came to watch and guide in person.

However, the size of the first generation of steam engines was very small, the large ones were more than one person tall, and the small ones were only chest-high, and the power was very low, so they had no practical value at all.

At that time, looking at the emperor's disappointed eyes, many academicians of the Imperial Academy of Sciences began to increase their horsepower and devote themselves to the research and development project of the steam engine.

Now six years have passed, the hard work pays off, with the support of strong manpower, material resources and funds, the Huangming Academy of Sciences has continuously improved the steam engine, and finally made significant progress!

The power of the first-generation steam engine is about one or two horsepower, and it can drive more than a dozen catties of weight, so that they can pull the train, it is better to smash it directly!

Now the steam engine played by the Royal Academy of Sciences can carry people, and when used as a car, you can imagine how much improvement it has.

Not long after, everyone walked out of the factory and came to an empty test site, and Zhu Cihong finally saw the world's first train!

Its shape is similar to that of the most primitive trains, and it can be described in one word: petite!

Seeing that this thing made a thunderous sound and was still emitting thick billowing white smoke, Xu Sheng hurriedly walked to the vicinity of the steam engine, watched carefully, and regardless of the heat, he reached up and touched it to see if this guy was in danger.

The officials were also curious, not knowing what kind of magic this thing did.

On the other side, Zhu Cihong was listening to Sun Heding introduce the development and improvement process of the steam engine.

The world's first steam engine was developed by Wang Zheng, an academician of the Mechanical Department of the Ming Royal Academy of Sciences, in the third year of Tianwu.

Wang Zheng, together with Xu Guangqi, was known as the "King of Southern Xu and North", and he had profound attainments in science.

However, the old academician is obsessed with the research of agricultural machinery, with the purpose of "benefiting people's livelihood and daily use", and is good at using agricultural machinery to help ordinary villagers save time and effort, and is not very interested in the research and development of steam engines.

Whenever spring and summer ploughing, the villagers drive these machines developed by Wang Zheng to work in farming, and they are all happy and happy.

The villagers called Wang Zheng "Kong Ming Reborn", and some women called him "the friend of women and the pillar of the family".

Moreover, Wang Zheng was nearly eighty years old at that time, and his physical condition was not good, and the improvement of the steam engine was completed by others.

In the fifth year of Tianwu, Wang Zheng took a half-year leave due to his physical condition, and the research and development of the steam engine was taken over by Bo Jue, an academician of the Ministry of Machinery. (The one who invented the Phoenix bicycle and the gun mirror)

When the first generation of steam engines was developed, Bo Jue was involved, he was very familiar with the principles of the construction of steam engines, and discovered two major shortcomings of steam engines.

The piston action is not only slow, but also discontinuous, and if this happens during intercourse, it can be called a tone and frustration, which can help flirtation.

But this is mechanical, so the problem is big!

This disadvantage makes the steam engine low utilization rate and very wasteful of raw materials.

When the cost of raw materials is greater than the cost of goods, this kind of production auxiliary steam engine will inevitably lose its value and will not be popularized.

After that, Bo Jue began to think of ways to improve, until he suddenly thought during a walk, since the low thermal efficiency of Wang Zheng's steam engine was caused by the condensation of steam inside the cylinder, why couldn't the steam be condensed outside the cylinder?

Since then, Bo Jue has the original idea of using a separator condenser.......

In the sixth year of Tianwu, Bo Jue designed a steam engine with a separating condenser, and theoretically calculated that the thermal efficiency of the new steam engine would be three times that of the first generation of steam engines!

However, theory is theory, and there is still a long way to go to turn the steam engine on the drawing board into a working steam engine.

In the next two years, Bo Jue worked hard to build several steam engines, but the effect was not as good as the first steam engine, because the separator was easy to leak everywhere and could not be started.

If it is an individual research, the huge cost of capital consumed during the period will definitely make Bo Jue go into debt, and even give up research.

However, the Ming Royal Academy of Sciences not only has the strong financial support of the royal family, but also has various configurations such as materials and processes, as well as a large number of personnel to be mobilized, and there are many scientific elites to discuss knowledge.

Bo Jue was not one in the battle, and soon, the first steam engine with a condenser was successfully tested!

Compared with the first generation of Wang Zheng steam engine, the second generation of Bo Jue steam engine has significantly improved thermal efficiency and can meet a large number of mechanical kinetic energy, and is known as the first steam engine with practical value.

In recognition of this great inventor, the Royal Academy of Sciences set the unit of power as "Bo Jue", referred to as "thin", symbol B......
