The big man has a living father

Chapter 110 Light Railcar! ( words updated)
Guangshen not only built a ship as big as an aircraft carrier to go to Yangzhou, but also built a super-large vehicle that could carry a hundred guards to patrol the north.

A hundred people can stand on the bus, so it's not a crowded bus.

These one hundred people are all here to serve Yang Guang, not to squeeze into the bus, so you can imagine how big this bus is.

Historical records show that the Turks were stunned when they saw the car, thinking it was a miracle and the gods were traveling.

The Turks are not unworldly people. Only God knows how big the car that makes them marvel at it is.

A human-powered aircraft carrier on land?

At first, everyone thought that these outrageous things in history were made up by the Tang Dynasty to vilify Yang Guang. Unexpectedly, with the continuous archaeological excavations and discoveries, those outrageous things were all true. Although the cart manufacturing base has not been unearthed yet, but... I'm afraid it is true.

According to the process of transporting golden nanmu to Chang'an, we can estimate the size of this cart.

Just the steel rollers, to carry such a large vehicle, would require a complete set of wheels to be replaced every two kilometers.

The amount of steel consumed by this car in traveling 100 kilometers is enough to arm 10,000 troops.

Only Guangshen, this outrageous prodigal son, could do this.

Coming back to his senses, Huo Hai said: "Your Majesty, I am conceiving a large vehicle with a very powerful transport capacity, but it needs to be on tracks. Perhaps in the future, your Majesty's special seat will be beyond imagination."

Huo Hai didn't want Liu Che to become like Guangshen after he became rich.

Even if money is spent, it must be positive and stimulate economic development.

Rather than being negative and stimulating the people to rebel.

Liu Che thought: "Oh? New stuff, track?"

Huo Hai: "I have discussed this in detail with Yang Liancheng from the research institute. During the Qin Dynasty, Qin Mo made a kind of track vehicle. It was not the sunken track used in the past for muddy fields, but a protruding wooden track, and the carriage ran on the track."

Liu Che frowned.

Liu Che had only one request for things from the Qin Shihuang era: I, Liu Che, wanted ten times as much as Qin Shihuang had.

"How many meters of track did the Emperor Qin build?"

Huo Hai: "It doesn't matter. Qin Chao's level is so low that he can only use wooden tracks."

Liu Che was a little afraid to think about it. If the track was not made of wood, could it be made of cement? How much would that cost?
"Stone tracks? Cement?"

Huo Hai: “Railroad tracks.”

Liu Che's heart twitched.

rail?

"Putting iron on the ground? What's the difference between that and spreading money on the ground???"

Huo Hai looked at Liu Che and said, "Your Majesty, the floor of your Weiyang Palace is covered with money."

Isn't floor heating the same thing as copper coins? The floor heating is covered with wooden boards, but you can't see them.

Liu Che: "That is the Weiyang Palace. No one dares to run away with it. You laid the iron on the ground. What if someone takes it away?"

Huo Hai: "Take them away? They need to be able to carry them."

Liu Che...

"What? It's so heavy that even people can't carry it? How much steel would that take?"

Huo Hai smiled: "It's already being experimented with."

What's the use of feeling heartbroken? Huo Hai also knew that the annual tax revenue of the Han Dynasty could not actually build many kilometers of railways.

However! With the prosperity of commerce, it won’t take long for the tax revenue of the Han Dynasty to surpass that of the Song Dynasty.

And as industrialization continues, the amount of wealth will far exceed the rate at which copper is mined.

Moreover, the technology of steel mills has been constantly innovating. Although each advancement is small, every small technological change has a huge impact on the increase in production.

By the time large-scale railway construction really began, steel production had already increased.

When Liu Che heard that the test had been carried out, he was stunned for a full minute.

Then he realized: "That's my money!"

"My money!"

Put my money on the ground! Is there still a king's law? Is there still law?

Huo Hai knew that it was too abstract to ask Liu Che to accept spreading the money on the ground, and he could not convince him: "Your Majesty will know why when you go and see it later."

Along the way, Liu Che was worried about the money.

He could imagine that the railroad tracks that Huo Hai mentioned must be thicker than he had imagined.

If this iron was made into knives, wouldn't the Xiongnu chop them into pieces?!
However, no matter how Liu Che thought about it, he never imagined that the rails would be so thick!
We soon entered the first stop of the mining area, where there was a railway track.

There was no need for Huo Hai to introduce it. Liu Che was not blind and he saw the shiny rails at once: "This?!"

However, the next moment, Liu Che saw a strange car driving out where the railroad tracks turned on the hill.

There are only four people in this car, all four of them are sitting in the car, but the car is moving automatically on the rails.

Although the rear section is a slope, the front section is flat. Where does the car get the power?

马呢？

No horse?

Looking closely, Liu Che saw four workers pressing a lever up and down.

The two men pressed the lever down, and the two workers opposite pressed the lever up.

Liu Che has seen this thing!
There is a seesaw in the open space of the Prince's Palace! Huo Haixiu gave it to the prince to play with!
Four people playing on the seesaw in the car! ?

But after a closer look, Liu Che gasped.

Behind the four people, there was a pile of coal that required at least ten people to pull with a cart!

So much coal, actually pulled by a cart!

Liu Che was stunned.

Liu Ju was even more dumbfounded.

Liu Ju originally liked this kind of thing. When he saw the rollers under the car running at a high speed on the rails, Liu Ju wanted to get closer to take a look!
Huo Hai began to introduce: "Your Majesty, when I was making the carriage before, I introduced the special features of your carriage to you. Do you remember?" Liu Che: "You said that the bearings on my carriage are difficult to make and are very smooth, so there is less friction and it runs fast. But the problem is, didn't you say that the tires need to grip the ground to run?"

Huo Hai: "As long as the rails don't derail, there's no need to rely on grip to stabilize the direction. The friction between the iron wheels and the rails is very small, and it's not easy to wear out. The traction required for a horse-drawn carriage to pull 100 kilograms can be used to pull this, and it can pull 500 kilograms."

"But it's not very convenient to always use horses, so we made a lot of these small rails to experiment with different power sources."

At this time, a solemn voice came from the side: "For example, the type they use is what I call a light rail vehicle."

"Every time they push down the lever, the gear chain and other equipment transmits kinetic energy to the wheel."

"The only difficulty is the reciprocating of the lever. The downward pressure on both sides should be opposite in principle. We spent a lot of effort to make this device into a seesaw so that the downward pressure on both ends can generate forward momentum."

The person who spoke was Yang Liancheng.

Liu Che looked at Yang Liancheng, who knelt down hastily: "Your Majesty, I am Yang Liancheng, a great scholar of the Mohist school!"

"In the past, Qin and Mo supported the tyrannical Qin, which caused chaos throughout the world. The Mohists are to blame, and I am here to take responsibility for this."

Liu Che waved his hand: "What crime have you committed? You were not born a hundred years ago."

"You are the executive vice president selected by Huo Hai for the Royal Research Institute, right? I agree."

"I am the dean of the institute, and you are the vice dean. How could I punish you for something that happened to someone else a hundred years ago?"

Yang Liancheng: "Common people..."

Huo Hai kicked Yang Liancheng on the buttocks, and Yang Liancheng finally understood: "Minister, thank you!"

Liu Che helped Yang Liancheng up and said, "Lord Yang, continue talking about this light rail vehicle."

Yang Liancheng cupped his hands and said, "Your Majesty, this railway is extremely expensive, but it represents the most advanced technology of this era!"

"In the past, it would have taken ten workers to push a cart to transport so much coal, or six horses to pull a cart."

Horses can pull very heavy loads, but they cannot carry very heavy loads for a long time. Mules have just been experimented with and have not yet become popular, so workers are actually more reliable than horses.

"Besides, this vehicle only takes one-tenth of the time it takes workers and horses to make a trip!"

Liu Che got the answer in seconds: "Twenty-five times the capacity."

Yang Liancheng: "Your Majesty, the workers have to go up with empty trucks after delivering the coal to the mine."

Liu Che: "Hiss~Fifty times the capacity!"

As early as when Huo Hai was building roads and manufacturing new horse-drawn carriages, Liu Che understood a concept: great transportation capacity means wealth!
If you want to get rich, you must first build roads, because roads can provide transportation.

And this road can actually increase the carrying capacity by fifty times?
Yang Liancheng: "Your Majesty, the driver's carrying capacity is limited. Even if he is well-fed, strong, and uses a good trailer, he can only increase the carrying capacity by half. We have only been researching this for a month, and the improvement has been quadrupled."

"This is the fourth model, and its transport efficiency is four times that of the previous model. Who knows how much it can transport in a year? In ten years, or a hundred years, it may be sixty, eighty, or even a hundred times."

Huo Hai: "Is it possible that it is a thousand times, ten thousand times, or a hundred thousand times?"

Yang Liancheng didn't believe it and stared at Huo Hai blankly.

Liu Che didn't believe it even more. Isn't this just bragging?

Huo Hai: "Remember the waterwheel in the paper mill? After the drive shaft transmits the power of the water flow, it only takes one minute to chop a big tree into wood."

"If we find a similar power source and install this device on a car, how much stuff can this car transport?"

Liu Che: “Hiss~”

Yang Liancheng widened his eyes: "This~"

Sir, your idea of ​​getting a budget is too bold, isn't it? Are you sure this is not just empty talk?
Huo Hai: "I remember that when you made this light rail vehicle, the first generation was built using the method of rowing, using a push stick and a pestle to push forward on the ground."

"The second generation is a round wheel. Turn the round wheel and use gears to drive the car forward."

"The third generation is a one-way pressure rod, why is the fourth generation a two-way one?"

Liu Che also looked at Yang Liancheng.

Yang Liancheng: "Because we didn't know how to use this new mode of transportation at first, we learned existing methods, including pulling carts and rowing boats."

"But we soon discovered that this vehicle could be driven so fast that nothing else could pull it unless the horse was running wildly."

"And horses can't keep running, so we used human power."

"The second generation used wheels. The worker on the vehicle turned the wheel once, and the wheel under the vehicle turned once. But after using this method for a long time, we found that the first step of turning was very difficult, and most of the time it was just spinning, wasting the workers' energy."

“But if the cargo capacity is increased to prevent idling, the workers will not be able to start the wheels during the first round.”

"We call this force that keeps moving after it starts habitual, or inertia for short, and the first cycle is called non-inertia, or inertia."

"Then we found that it was difficult to turn the wheel, but the workers could easily overcome the inertia by using their own body weight to press down. To turn the wheel, they used their arm strength, and to press down, they used their weight the first time, and only started to use their arm strength from the second time onwards."

Liu Che understood: "Finally, you found that the force of lifting the pole by pressing down once was wasted, so you made a two-way pressure pole. Four workers sat opposite each other. When two workers on this side pressed down, the pole on the opposite side would be lifted up. When the two workers on the opposite side pressed down, this side would be lifted up. You tried every possible way to make the two downward forces work in the same direction?"

Yang Liancheng nodded vigorously: "Yes, Your Majesty, that's it."

"We currently think the fourth-generation solution is more convenient and reliable, so we are optimizing the mechanical structure."

Liu Che exclaimed: "What a great discovery and great progress! If this is the case, the mechanical structure of this car may continue to improve."

"And just like Huo Hai said, you used thrust and traction at the beginning, but later you discovered a way to transmit force using mechanical structures. The source of that force may not be impossible to improve."

"If a windmill is placed on this car, it may be too strenuous. But if we can find a force to replace the windmill, this car may really be able to pull hundreds or even hundreds of times the weight."

Yang Liancheng said sincerely, "Yes, Your Majesty, so, can you give the research institute more budget?"

Liu Che: “Budget?”

Yang Liancheng: “It’s research and development funds, money.”

When it comes to money, Liu Che is not so open-minded and easy to talk to: "First calculate how much the current railway track is losing."

Yang Liancheng took out a notebook and said, "In theory, this railway can make money. As long as it operates continuously for 430 days, the remaining wages for workers and food expenses will exceed the price of the rails."

When Liu Che heard this, he said, "What if it breaks down after 430 days of use?"

Yang Liancheng: "This is the problem our institute wants to study!"

Liu Che thought for a moment and said, "The money issue will be discussed last at the meeting. We will hold a board of directors meeting first, and then a general board meeting."
