The people waiting for the train to return at the starting point immediately boiled, but because Zhu Zhanji was there, they could still keep their composure.

When Zhu Zhanji rode a horse and galloped towards the scene of the accident, they couldn't contain their curiosity and ran to follow.

Xiamaqiao Farm is now the most famous neighborhood in the outer city of Yingtianfu in addition to Chang'an Fang and Taiping Fang.

The earliest underground roads in the Ming Dynasty, the earliest cement roads in the Ming Dynasty, the earliest green scenic spots, and the residential areas and research institute areas with strict and unified design have formed a large garden community.

Because of the existence of the research institute, the Xiamaqiao Farm is not open to the public, and outsiders are not allowed to enter even if they can see this beautiful land from the north road of the farm.

To the south of the farm, there is a tributary of the Qinhuai River, which just separates the farm from the Temple of Heaven and Earth in the south.

When the farm was first built, Zhu Zhanji strictly required that the construction of houses within 100 meters of the river was strictly prohibited, leaving a park within 200 meters of the north and south of the river.

The innermost part of the park is dominated by weeping willows, in the middle is a large field of various flowers, inlaid with various bonsai-like landscape trees, and on the outermost side is the evergreen pines and cypresses transplanted from the mountains.

Although this park is not wide, it is very long, from the Zhengyang Gate of the imperial city, to the east, continuous about three kilometers, forming the largest scenic spot in the southeast of Yingtianfu.

After the completion of this place, it has become the favorite place for the people of Yingtianfu. Including which green buildings, painting boats, when the river is not forbidden, also like to come here to do business.

It's just that, because of the blockade of Yu Linwei, they can't set foot on the north shore, otherwise, they will be imprisoned for at least a month, and then they will be punished if they find out that they are not spies. If he were a spy, the crowd would never hear from him again.

The new railway line loops around the residential area, on the southern line between the park and the residential area. As an experimental railway, although it is only three kilometers, it is sufficient.

The scene of the crash is not far from the place of departure, on the east side of the northern line, where the turn to the south is located.

Now, in addition to the front of the car has not been overturned, the four cars behind have been turned over to two, and two more have also been derailed.

But fortunately, because the car has no roof, when it rolls over, although some people are not lightly fallen, and even a few unlucky people are seriously injured, most of them are not much troubled.

When Zhu Zhanji arrived, they had already begun to save themselves, and moved the injured people aside to wait for treatment.

Many of the people who watched the excitement were the doctors of the hospital, who immediately treated the scene on the spot, and then asked people to pull the carriage to pull the seriously injured for treatment.

After the injured people were transported away, Zhu Zhanji and a group of engineers began to investigate the scene, wanting to know why the car overturned.

Car accidents, even in the Ming Dynasty, were not uncommon.

Since livestock was used as a power source and became the main means of transportation, various car accidents have occurred one after another since ancient times.

Car accidents caused by livestock madness, car accidents caused by wrong cars, there are dozens, even hundreds, of car accidents in Yingtianfu every year.

But there has not been a car accident as serious as this one.

The cause of the accident was quickly clarified, when the train was turning, because the tracks were wooden and could not withstand such a large gravity, it could not hold the vehicle in place, and the wheels fell off.

"Your Highness, the wooden track cannot be effectively fixed when the center of gravity of the vehicle is offset due to the insufficient correction rate. But...... If all the rails were replaced with iron, the cost would be too high. ”

Zhu Zhanji looked at the torn stubble on the rails, shook his head and said, "No, just use the wooden rails." ”

He was well aware of the history of railways, which were made of wood in the beginning.

Now that Daming has directly transitioned to the final stage of the wooden rails, the wood is dried, and then asphalt is added for anti-corrosion and insect treatment, and on this piece, there should not be much of a problem.

Now the overturn, on the one hand, the load-bearing structure of the vehicle lacks spring shock absorption, and on the other hand, the design of the wheels is unreasonable.

Today's wheels are only about 20 centimeters in diameter, which is pitifully small compared to the train wheels of later generations.

After Zhu Zhanji saw it at the beginning, he didn't care, because the wheels of the minecarts in later generations were also very small.

But he ignored that the kind of wheels are small, because the track is made of iron, so the two sides are more stable.

Now the track is wooden, but with small wheels, it is naturally not fixed now.

He looked at the exposed wheels under the toppled carriage and said, "Enlarge the wheels, in addition to the fixed support on the inside, and also curve on the outside to wrap the rails." ”

Ma Zhicai said with some embarrassment: "Your Highness, in this case, the wheels will be too big, too heavy, and difficult to quench. ”

The material technology of the Ming Dynasty is not up to par, and now although it can obtain stainless steel, it basically takes out guns and cannons.

Civilian commodities for train seats need to be subject to cost control. Completely stainless steel to make wheels is too expensive.

Therefore, the wheels are now made of iron, and then after the wheels are processed, they are quenched to increase the strength.

Iron wheels with a diameter of more than 50 are nearly 10 centimeters thick at the widest, and the weight of this wheel is several hundred catties.

At this time, the quenching process is carried out, and the corresponding technology needs to be improved.

Zhu Zhanji asked again: "Is the transmission part problem easy to solve?" ”

Ma Zhicai looked at a deputy in his forties, and he immediately bowed down and said, "Your Highness, it's not difficult to solve. Nowadays, the wheels are pushed by connecting rods, which has been tried many times. Originally, we had tested the car many times and there were no problems, but this time it was also because there were too many people in the car, and it was too heavy, which led to a rollover. ”

Zhu Zhanji shook his head and said, "In my opinion, there are still many problems. First, the load-bearing structure of the load-bearing wheels and the carriage still needs to be improved. I believe that adding shock absorption to the articulation will not only increase the comfort of the occupants, but also prevent rollover.

Second, there is a lack of connection between the two wheels, so we should design a connecting rod to connect the two wheels so that the wheels on both sides are always in the same direction, which can also increase power and stability. ”

Although Ma Zhicai didn't know if this was useful, he immediately bowed down and said: "Your Highness is wise, Weichen immediately organized manpower to solve these problems." ”

Zhu Zhanji shook his head and said: "My thoughts are not necessarily correct, as a researcher, you must always face any problem with a skeptical attitude." It's only when the new technology is proven that it's not too late to tout it. ”

At this time, a carriage drove over slowly, and Zhu Zhanji knew that it was Lan Yan's car as soon as he looked at the appearance.

Baiguan immediately gave way to a lane, and after the car stopped, the two palace maids immediately stood at the door of the car and opened the door.

Zhu Zhanji took a few steps forward, came to the side of the carriage, stretched out his hand in person, and the blue smoke wearing a fence on his head helped Zhu Zhanji's hand get off the car. "Why are you here?"

Zhu Zhanji's actions are somewhat deviant in this era.

Because in this era, the status of women is very low. But in order to pick up the blue smoke, Zhu Zhanji didn't mind being more gentlemanly at this time.

Lan Yan was arranged by Zhu Zhanji in Xiamaqiao, which actually caused a lot of turmoil, and several times in the early dynasties, there was a royal history of the Metropolitan Procuratorate who persuaded Zhu Zhanji that women should not be allowed to show their heads.

It's just that Zhu Zhanji didn't take care of it, but Xiamaqiao was his private property, and he let one of his wives take care of it, and he didn't exceed the rules and brought these people back.

Lan Yan took over the Institute of Chemistry and the Institute of Medicine, and the personnel of the Institute of Chemistry didn't dare to say anything when they saw Lan Yan's ability.

They can't wait to learn all about how to make explosives from Blue Smoke right now.

As for the Medical Research Institute, Lan Yan didn't care about it for the time being, and only when he made achievements would everyone be convinced.

In fact, Zhu Zhanji has decided to let Lan Yan take care of the entire Xiamaqiao, but he has now learned to keep a low profile.

Many things, it doesn't have to be known to everyone at the beginning, you just need to let Lan Yan do things first, and when everyone is used to her existence and can't do without her, it's not too late to announce it.

Seeing the scene in front of him, Lan Yan whispered, "The concubine heard that there was a car accident here, so come over to see if there is anything you can do to help." ”

Zhu Zhanji nodded and said, "You came just in time, more than 40 people were injured today, and all of these people were treated as work-related injuries." Even if he is hospitalized, he will still be treated free of charge. You'll take care of it for me. ”

When the others heard this, they immediately raised Lan Yan's status a lot. Many people are wondering if this development continues, will His Royal Highness hand over all the Xiamaqiao Farm in the future to Lan Liangdi?

However, they did not resist much, because there were almost 3,000 Xiyi people living here in Xiamaqiao. They all heard that there were not only female ministers in Xiyi, but also women who became kings.

As the first to accept these Western ideas, they did not have much resistance to a future concubine taking care of this private property belonging to His Royal Highness.

Lan Yan nodded and said, "Your Highness, please rest assured, the concubine will definitely handle this matter properly." ”

Zhu Zhanji said to Ma Zhicai again: "There is no need to blame anyone for today's events. The emergence of any new thing is not smooth sailing. Only with the spirit of fearless dedication can the development of Daming get better and better. The same is true for all kinds of experiments in the future, every researcher, if there is a casualty due to the experiment, Lone will definitely take care of his whole family, and will never let anyone shed blood and tears. ”

At this moment, everyone became excited, and they knelt down and said, "Your Highness is wise." ”

Zhu Zhanji said to Lan Yan: "You are responsible for drafting such rules and regulations, can you do it well?" ”

This is to earn a reputation for Lan Yan, of course she knows this, squatted slightly and saluted: "The concubine body must not disappoint His Highness, and will not disappoint anyone in the Xiamaqiao Farm." ”

Zhu Zhanji waved his hand with satisfaction. "Get up....... Drive back to the palace. ”

Hundreds of ministers did not get up, but bowed their heads again. "Greetings to Your Highness."

Although today's train test run failed, Zhu Zhanji was not disappointed.

Discovering and solving problems is a process of scientific research.

Now that the idea of the train has been accepted by everyone and a prototype has been built, is it still far from the official operation of the train?

Zhu Zhanji was about to get into the car, but saw a few excited figures running on the road. The first one of them was mantle, looking like a madman, but Yu Linwei's people didn't care about him.

"Your Highness, Your Highness......"

Hearing the voice, Zhu Zhanji recognized that the person in front of him turned out to be Ma Di.

At this time, Ma Di looked a little like a mad scientist, and seeing his excited appearance, Zhu Zhanji's heart moved and he stood in place.

Madi quickly ran to him and said breathlessly, "Your Highness, the electric motor ...... I made the electric motor that His Highness wanted......"

Zhu Zhanji couldn't help but take a step forward and grabbed his arm. "Really?"

Madi immediately screamed. "It's broken, it's broken."

Only then did Zhu Zhanji come to his senses, and immediately let go of his arm and asked, "Is it really done?" ”

Ma Di rubbed his arm and shouted, "Wechen drilled a hole in the iron sheet with an electric motor, Your Highness, please look at ......"

Everyone else didn't understand Zhu Zhanji's excitement, even Lan Yan didn't understand, in her opinion, instead of spending time researching electric motors, it was better to make light bulbs.

But only Zhu Zhanji knows that only with electric motors can human civilization truly enter the era of electricity and civilization.

The application of electric motors, which may seem inconspicuous, is a big step forward in human civilization, which is even more important than steam engines and penicillin.

In almost all aspects of later generations, from automobiles, ships, rockets, to razors, refrigerators, and almost all electrical appliances, the existence of electric motors is inseparable.

However, Zhu Zhanji did not understand the working principle of the motor. When he was in elementary school, he also used a small motor and a battery to make a small fan and a small drill.

But why the motor has power when it is connected to electricity, he does not understand at all.

This allows him to only know the direction but not the process when directing power research.

It's not like a steam engine, he can still tell one, two, three, and know how it works.

Therefore, Da Ming was already able to make generators four years ago, but he could only be used by Zhu Di as a tool to pretend to be a ghost.

After returning from going to sea, the people of the Electric Power Research Institute have been able to wind the coil of the electrocuted man, but there is still no direction for the application of electricity.

The electric light that everyone in later generations knew had no concept in their hearts.

Zhu Zhanji knows that the production of electric lamps seems simple, but the process is quite complicated.

Moreover, tungsten filament, which is most suitable for filament, has the highest melting point in metal, requiring a high temperature of 3,000 degrees.

Daming now uses oxygen blowing and pre-embedded heating to increase the furnace temperature, which can produce the temperature of melting steel, but it is less than 2,000 degrees.

So he didn't think about electric light for the time being, first of all, it was difficult, and secondly, it was not indispensable.

The electric motor is different, which is indispensable.

Today's generators in Daming are fixed coils, rotating magnets, and generating electricity.

Zhu Zhanji asked them to do the opposite, using a generator to generate electricity, and then driving another set of coils to generate electricity to drive the shaft to rotate.

Not looking into how it works, just reasoning backwards. In the past few months, the people of the Electric Power Research Institute finally made the motor.

Zhu Zhanji was very happy, and immediately said, "Take me to see." ”

This time, there were many fewer people following Zhu Zhanji. The motor is still a confidential project, and most people are not qualified to know.

The people of the Mechanical Research Institute are still a little unconvinced, and the Electric Power Research Institute was originally just a branch of them. They even made a steam car, and His Highness was not so happy, but now he was so happy because of a small electric motor.

But most people are curious, what exactly is this electric motor?

Seeing the simple equipment in front of him, Zhu Zhanji squatted down without disgust and observed carefully.

This is a set of reverse guided power device, which can drive the magnet to rotate by pedaling the transmission equipment by manpower, and then generate electricity through the coil.

The electricity generated is connected to the coil of the motor, and then the magnet on the axis of the motor is driven by electricity, which drives the axis to rotate.

It is this rotation that is the working principle of the electric motor.

You can use this kind of rotating circle, which is directly installed with a fan, which can also drive drilling machines, lathes, including car starting, etc.

It seems like a simple working principle, but it is the foundation of the entire Second Industrial Revolution.

Madi installed a set of clamps at the top of the shaft, and then a drill bit that, driven by electricity, easily drilled a hole in a piece of wood.

Whether it is a generator or an electric motor, the coils and magnets are all exposed, without any beauty, but Zhu Zhanji is fascinated by it.

Ma Di said softly: "Your Highness, the minister has tested a variety of materials, and it is still copper that has the best conductivity, and this coil has the best effect of winding it with copper wire. ”

Zhu Zhanji nodded and said: "You have three research directions next, the first is to study how to draw the copper wire thinner and thinner to make a smaller or larger motor. ”

Ma Di nodded and asked, "According to His Highness's teachings, the minister has designed a variety of uses for electric motors, and in his opinion, this electric motor can not only replace hydraulic machinery, but even replace the role of steam engines." ”

"Yes, that's the second direction. Different motors can be used in different places. And then there's the third, and most important, study, which is how to use hydropower and wind power to generate electricity. ”

The principles of power generation, including circuit transmission and voltage balancing, are actually very basic disciplines.

Today's research is only about piercing a layer of window paper.

As long as you have a basic sample and then understand the basic principles, you can apply many techniques.

For example, hydroelectric power generation is nothing more than driving the blades to rotate through hydraulic stamping, and then driving the rotor to generate electricity, and the same is true for wind power generation.

As for how high the voltage, how to transmit electricity, and the classification of electricity, the most suitable method can be slowly found in future practice.

Zhu Zhanji is already considering building a few wind power towers on Zhongshan, even if the power supply is limited, it can also ensure the power research here of the institute.

As for hydroelectric power generation, it is more difficult for Daming, because there is no suitable place to build a hydroelectric power station around Yingtianfu.

For example, the construction of a hydropower station in the Three Gorges is simply not something that can be done by the current technical means of the Ming Dynasty.

However, it is still possible to build some experimental small hydropower stations, because both power generation equipment and transmission equipment have been slowly studied and improved.

But by this time, Zhu Zhanji's expectations for electric lights were also higher.

He was fed up with the darkness everywhere at night, and if he didn't care about the cost in the palace, he would have had more candles and lanterns to light at night.

Before he could say it, Lan Yan couldn't help but say, "Your Highness, we can install electric lights in the palace......"

Madi, who was thinking about a hydroelectric power station, raised his head and asked, "What is an electric light?" ”

Zhu Zhanji looked at Lan Yan and said, "I don't know how to make light bulbs?" ”

Lan Yan smiled: "What's complicated about this, isn't it tungsten filament...... No, Daming can't melt pure tungsten now. Then use bamboo charcoal wire. This carbonized bamboo silk is just a small experiment, and I should be able to make it after a few attempts. ”

Zhu Zhanji was overjoyed, looked at the sky and said, "Ma Di, you freshen up, we will go to your glass workshop now." ”

The carriage slowly drove all the way from Xiamaqiao Farm to Fangshan, and the attendants and Yu Linwei sent out the vanguard to prepare for Zhu Zhanji's arrival.

In the carriage, Lan Yan was popularizing chemical knowledge with Zhu Zhanji. "Glass is actually silica, and since the Ma family has mastered the production of glass, it is not difficult to make light bulbs. In addition to incandescent lamps, I can also study high-pressure mercury lamps in the future, but fluorescent lamps are not easy to do because they require ballasts, which I don't understand. ”

Well, Zhu Zhanji doesn't understand either. He only knew that fluorescent lamps had the highest luminous rate, but when the electricity was turned on, a ballast would jump a few times before the lights would come on.

As for how it worked, he didn't know anything.

However, he was satisfied with having a blue smoke to help him solve the light bulb problem.

"The carbonization of bamboo silk is actually very simple, the bamboo wire itself is not conductive, but the carbonized bamboo silk is a conductor of electricity like a carbon rod, but it is much thinner than the general carbon rod. I don't remember if it was the original carbonized bamboo wire, or if the bamboo wire was carbonized and reshaped, but this is only a small problem, and it bothers me. ”

Zhu Zhanji found that the blue smoke at this time was radiant, and when it came to her professional eyebrows, she was really happy at such a time.

When the convoy arrived at Fangshan, it was already sunset, and Ma Zhide's family had already been notified and waited at the gate of the workshop.

This is the most secret place of glass manufacturing in the Ming Dynasty, and the prisms in the telescope, including the convex lens and concave lens of the microscope, are all produced here.

Although there are some glaze workshops in other places, there is no glass that can be made with better purity than here.

And this place is also protected by Yu Linwei, ordinary glass workers are not allowed to enter the production site of prisms and precision lenses, and those high-ranking workers, including their families, are protected.

Ma Zhide already knew that it was Lan Yan who came with him this time, and he met with Lan Yan a few days ago, and made a microscope with a higher magnification according to Lan Yan's requirements.

He was not surprised to see Lan Yan, but just bowed slightly, hugged his fists and said, "I have seen Your Highness, Liangdi." ”

Zhu Zhanji waved his hand and said directly: "No need to be polite, I came in a hurry today, and I will bring Xin'er back next time." ”
