The big man has a living father

Chapter 246 Tram
The changes in Chang'an City have become very difficult to understand and see clearly.

However, inside the institute, the situation is quite different.

To be honest, if Huo Hai didn't want the record left in history to be "Huo Hai invented the generator", "Huo Hai invented the electric light", "Huo Hai invented the motor", he would have made these things long ago.

Even for something like a motor, as long as Huo Hai can pull out the copper wire, he can rub the motor by hand.

Isn’t this a basic ability for four-wheel drive enthusiasts?
Although Huo Hai couldn't make a record-breaking motor himself, he did try to wrap electric motors to keep up with the trend.

Although an electric motor is not equal to a motor, a motor is equal to a motor, and it is a motor of a relatively high level.

But even if Huo Hai did not take action, the most basic generators, motors, and electric lights had already been invented.

Huo Hai calculated the time and found that six years had passed since the theory of electricity was born.

Six years have passed, and it is still unclear who invented the motor and generator.

To be precise, the original steam turbine was made by Erkuan and his team.

But that steam turbine was very different from the steam turbine that Huo Hai knew.

It uses the same principle as a steam engine, using boiled water to create steam that drives the turbine to generate electricity, which is then transmitted to distant locations using wires.

To put it simply, we made a coil structure for generating electricity, connected it to the steam engine with a rotating shaft, and replaced the piston structure of the steam engine with a steam turbine.

That was the first generation of steam turbines.

It should be said that Erkuan, Fadi and Huang Jiao each invented part of this primitive steam turbine.

Combined together.

After these few years, the structure of this original steam turbine has been improved.

From the cylinder structure, to the trachea structure, to the steam turbine structure, adding a second steam turbine, reverse steam turbine, steam turbine opening direction, shaft sealing technology, and shaft fine structure.

Improve step by step.

It has been improved to the present day, and it is really hard to say who invented this thing.

The improvement of the motor is one thing.

This is especially true of electric lights.

The production of this electric light is a matter of luck. Only with enough experimental materials can we test out the one that is truly reliable and usable.

This is purely based on luck.

Maybe you can find the answer after ten tests, but if you try again, it may take one hundred thousand tests before you can find the answer.

The most terrifying thing is that now, all of this is concentrated in the research institute.

In previous lives, during the first and second industrial revolutions, chemistry, physics, materials science, and various cutting-edge technologies were scattered across more than a dozen countries, and the time span was also very long. Perhaps the materials used in a new technology had actually appeared decades ago, but were forgotten because of the long time.

Sometimes a technology is invented but there is no material for it. Even in the 21st century, the technology has become outdated and suitable materials have not yet been found.

For example, the Tesla turbine structure.

But in today's Han Dynasty, this is not the case at all.

Ninety-nine percent of the world's scientific research is concentrated in Chang'an.

Ninety-nine percent of Chang'an City's top scientific and technological research is concentrated in the Royal Academy, and at least 60% to 70% of various theoretical technologies and cutting-edge technologies are also in the Royal Academy.

In this case, it is really difficult to experiment with electric light materials.

Because it’s very easy to go astray.

Sometimes, when you experiment with a certain material, you find that it can light up for a very long time.

Thought I found the answer.

But in fact, it is possible that this material is the one that can light the light the longest among this family of materials, and it can suddenly change the direction of the entire research and cause the whole thing to go astray.

And this kind of material is in abundance in the institute.

Since wood tar was distilled into several materials and the chemical industry era began, Huo Hai has no idea how many chemical products are currently made from petroleum and coal. Among them, there are more than 200 chemical products with clear efficacy that are already in normal use on the market.

Including those for disinfecting scalpels, they have been innovated for two or three generations.

Therefore, having too many materials is actually a torture for inventions that require exhaustive experiments.

However, power facilities are still deployed throughout the institute.

All experimenters are both experimenters and experimenters.

Since everyone has his own experiments to do, he also has to become an experimenter for the entire power system.

Huo Hai hasn't been to the institute for some time.

The population of the current research institute has expanded significantly, with the third generation becoming the main driving force.

Most of the second generation brought up by Huo Hai were workers themselves. They changed their careers to learn new things and transfer technology. Their research was both good and bad. The good thing was that they were experienced and had not received formal training, so their research was imaginative and sometimes there were many outrageous studies, but some of them really worked.

The third generation is different. They have received a long period of new academic training, a long period of engineering training, and have accepted the experience instilled by the second generation.

So when they conducted experiments, they were not fanciful, but took a steady and cautious approach.

The entire institute is thriving.

As soon as Huo Hai entered the research institute area, his carriage was stopped.

Huo Hai peeked out the window and saw a familiar researcher: "What do you want to do?"

Huo Hai thought he had some questions to ask.

So the boy talked to Jiang Buyi about something.

Jiang Buyi turned around and said to Huo Hai, "Grand Minister of Agriculture, they want you to get off the train and either take the steam train or the tram."

Huo Hai raised his eyebrows: "Hmm?"

Jiang Buyi whispered: "The various research results in the institute need to be tested, but there are regulations that electrical equipment is not allowed to be used outside, so the institute simply tests the various research results internally."

"Because there are so few people in the research institute, everyone has to participate in various tests."

Huo Hai nodded: "I understand, you are treating me as a guinea pig, okay, let's change it."

In fact, Huo Hai knew about this, but he just forgot about it.

This matter was proposed by Chen An.

As the vice president of the Technical College, Chen An's presence is much lower than that of Yang Liancheng, the vice president of the research institute.

The main reason is that Chen An’s personality is not as obvious as Yang Liancheng’s, not that he really has no presence.

After all, all these top students in the institute have been trained in his technical college and have become the best there before they can come to the institute.

So in fact, Chen An’s status within the institute is still very high.

Although the suggestions he made were not mandatory, almost everyone was willing to listen to them.

The reason why Chen An raised this point was because of his identity as a master craftsman and the successor of Lu Ban.

Chen An has always believed in Lu Ban's "Missing One Door".

But now, Chen An gradually understood the reason for missing a certain thing.

Safe production and skilled production are big issues.

First of all, it is dangerous if you are unskilled. Secondly, it is even more dangerous after you become skilled. Only by following the safety system can you truly ensure safety.

Otherwise, randomly taking away hands and feet is no joke, even randomly taking away family members is normal.

Didn’t Ge Nan die because he caused the explosion of his stockpile of nitrocellulose while doing other gunpowder experiments?
Therefore, Chen An proposed the idea of ​​conducting electrical equipment experiments in the research institute.

The reason is very simple.

The researchers needed to use the things themselves, and they were well aware of the horror of electricity. They could easily kill a cow, let alone a human.

Putting these two points together, they have to be the experimenters to ensure the safety of the experimental subjects.

After getting off the car, Huo Hai looked at the new generation steam car and then at the tram next to it.

This tram is rather rough, with various devices hung directly on the car body and various wires exposed. Although covered with rubber, it looks messy.

In sharp contrast, the telephone poles and wires on the roadside are orderly and neat.

Huo Hai looked at the tram and it didn't look like a semi-finished product of the research institute, but rather a preliminary product that was forcibly brought in for experiments.

"This was designed by the prince, right?"

The researchers nearby nodded.

Huo Hai chose the tram side.

Before getting on the bus, Jiang Buyi walked to the front of the bus and squatted on the ground to look at it. Huo Hai stopped and the other researchers also looked at Jiang Buyi.

After reading the structure, Jiang Buzhi was shocked.

"Oops."

Huo Hai: “What?”

Did you see the gunpowder bag? What's that expression?
Jiang Buyi said angrily: "This...the mechanical structure of the car is very similar to the structure my teacher studied!"

"I didn't expect that the research directions in the institute were the same. This research was in vain. I can only iterate when I go back."

Huo Hai leaned back tactically and got into the car.

In fact, the tram technology is not very difficult. To be precise, the original version of the tram is not difficult.

With the level of young people in the 21st century who watch short videos about power accident investigation every day, they can easily understand the power layout here.

This thing can't run fast, at most the motor will stall.

If there was a problem, it was an electrical short that caused the rubber to burn through and the wood of the car body to carbonize and catch fire over time.

However, at first glance, Huo Hai couldn't see any structural problems, so he got in the car.

Jiang Buyi was still sighing that good design requires telepathy, but the researchers next to him were making eye contact.

Jiang Buyi, doesn’t he know that his teacher is the prince?

No wonder the prince ran away immediately when he saw the Grand Minister of Agriculture coming.

It turns out that the person he was hiding from was not his brother-in-law, the Minister of Agriculture, but his apprentice.

After Huo Hai got on the tram, he found that there were electric lights in the tram.

I don't know what generation of light bulb this is, probably a test product.

Installing test items inside test items can be considered as giving them access to their use.

When the tram started, Huo Hai's face changed.

What a powerful motor.

How come there is no gear change and it starts at full power?
The car wasn't even started, but it was running at full power. The smoke it emitted was more than the exhaust of an internal combustion engine!

After looking again, I found that the car was not moving. After turning my head, I found that the rear wheels were turning on their own, but the front wheels did not move.

Huo Hai pinched his chin.

This is obviously caused by insufficient grip.

But trams don't have much grip, so is it sandblasted?

Huo Hai thought about it carefully and felt that this might be a problem with the drive shaft.

In other words, there is a problem with the motor not being installed in the front.

There is a motor at the back but not at the front. The front wheels are not moving, and even if the rear wheels turn, they cannot drive the car in a short time.

Why is there no motor installed on the front wheel? Or is there no drive shaft installed between the front and rear wheels?

You have to know that when Huo Hai was five years old, he played with a four-wheel drive car and knew that a car with a drive shaft runs faster and more steadily than a single rear-wheel drive car, and can cope with more situations.

After careful observation, Huo Hai discovered the problem.

In this tram, the driver sits in the middle.

If you look at the structure, the steering wheel gear should be directly connected to the front wheel axle.

Installed in the middle.

This steering mechanism takes the place of the transmission shaft.

There is not enough space for the front motor.

If the driving seat is moved to the left, leaving the middle empty and providing the drive shaft, the same power can prevent such crazy slipping.

At this time, the driver was observing the amount of motor smoke.

He is trying to decide whether the car can start or not.

If the car starts turning, then go ahead and there will be no smoke next time.

If the car doesn't move, you can't continue. If you step on the accelerator again, it will catch fire.

Luckily this time the car started moving.

After the car started and drove for a while, the driver felt relieved and asked, "Grand Minister, is there anything that can be improved in the design of this car?"

Huo Hai: "It is definitely not possible for the rear wheels to rotate without the front wheels rotating. If necessary, a transmission shaft should be added between the front and rear wheels."

"Your wheel cannot be made the same as a train wheel."

"The tracks of a train are raised and the wheels are sunken, but for a tram, it would be best if the tracks were sunken and the wheels were sunken."

Trains are the exact opposite of horse-drawn carriages.

And now, the tram tracks happen to be the same as those of horse-drawn carriages.

The reason is weight.

The concave structure of the train means that the wheels have two track walls, forming an [n]-shaped opening. If the wheels are convex and the tracks are concave, the wheels are [I]-shaped.

Same thickness, half the weight.

What a concept! This is a pure metal wheel!
If each of the four wheels is missing half, that would amount to several hundred kilograms of weight.

Wouldn't it be better to put these hundreds of pounds on a larger motor? Wouldn't it be better to put them on the front windshield?

After hearing the two suggestions, the driver's eyes lit up: "Grand Minister, any more?"

Huo Hai: "Also... are you going to build the car or should I?"

"How about this, I draw a blueprint and start producing the tram, and you guys stop researching?"

The driver laughed awkwardly when he heard this: "Come on, Mr. Si Nong, you eat the meat, and we can have some soup, right?"

Huo Hai: "I am not interested in trams. Even if I really invest, I will invest in the development of new trains."

In fact, it is not a hypothesis. Huo Hai is investing madly in the research and development of new trains, but they only burn heavy oil.

The construction of railways in the north is related to energy, so Huo Hai and Liu Che did not bring it up for discussion.

In everyone's eyes, transportation is the lifeline of the Han Dynasty, and the development of the transportation industry means the development of the Han Dynasty.

Therefore, everyone who encounters an opportunity like Qian'an Railway will definitely invest in it and want to get a piece of the pie.

But in reality, energy is the basis of transportation.

By holding the energy and setting prices at will, one can continuously extract commissions from transportation.

And once it becomes a pattern, others have no way of opposing or resisting it.

The northern line passes through various energy bases and connects more than one million people on the road. In addition, a large number of people from Weiman Korea will be migrated there. Under the current policies, these people will develop into energy workers and maintain this position for a long time. Since there is no shortage of workers and mines, the northern energy line can be maintained for a long time and can almost survive the first three industrial revolutions.

However, Huo Hai no longer cares about these investments.

That’s right, this 1,700-kilometer-long railway is of no use to Huo Hai and Liu Che.

Now that urbanization has begun, they need to continuously buy land from Huo Hai and Liu Che, build houses, and sell them to workers.

Maybe they think that it is a good profit since the land price only accounts for 30% to 50% of the development cost.

But when all this money was pooled together, it allowed Liu Che and Huo Hai to spend money like crazy to build the main transportation arteries during this period.

Eight years ago, when building a 50-kilometer railway, the sight of the iron being laid on the ground was enough to kill Liu Che.

A few years ago, Huo Hai and Liu Che made a desperate effort to build a 300-kilometer railway.

Nowadays, railways of a thousand kilometers are just like this.

Huo Hai was more interested in trams.

Unfortunately, Huo Hai knew very well that the era of trams was in the future, not now.

When did the internal combustion engine appear?
The emergence of the steam engine did not require Huo Hai to point it out or deliberately manufacture it, so what about the internal combustion engine?

Is it really because the quality of steel is too good that the oil and gas expansion phenomenon of the internal combustion steam engine could not be discovered by mechanics, and the technology required for the internal combustion engine could not be summarized?
After Huo Hai got in the car and left, the prince came out from the darkness and looked at the car in the distance.

Shi De: "Prince, have you made your decision?"

Liu Ju put his hands behind his back and remained silent.
