Five days before the new year.
"Teacher, teacher, we succeeded, we moved! We moved!" Ren Baqian was sitting in the room when he heard the voices of students yelling from outside the window.
Ren Baqian closed the book in his hand, he has been paying attention to the progress of these students, he thought it would be earlier.
I just adjusted the connecting rod of the steam engine and installed the wheels. I didn't expect it to be successful for nearly two months.
It is said that there is great power in numbers, and the power of the ancient people is indeed great, but they can be slow in this matter.
However, among so many students, there are quite a few who are lagging behind, such as Tonglan. If they are excluded, it may be half a month earlier.
While Ren Baqian was still in his room, he could hear the cheers of many students from the backyard. He walked over with his hands behind his back, and saw dozens of people surrounding a huge tractor...
Well, it's really a tractor. The overall appearance is very similar to the tractor Ren Baqian saw when he was a child, but it is rougher and simpler.
The cylindrical steam engine is at the front, and there is an exhaust pipe on it. .
At the back is an empty iron plate filled with coal. Standing on it, one person continuously adds coal to the front stove, and then the stove heats the water tank. into the front cylinder.
At the same time, these students also made use of the characteristics of water and steam conversion to make a diversion tube under the cylinder, which can send the cooled water back to the water tank from the lower diversion tube.
As for the bottom, there are two large flywheels plus six gradually shrinking flywheels, which are no longer connected by animal tendons, but replaced by metal connecting rods.
When Ren Baqian arrived, Du Laoliu was adding coal to the stove in the car with a disheveled face and shirtless arms.
"It's moving!" Many students cheered: "It's been a long time, and finally a steam car that can move without manpower!"
Whether it is Shi Gan who is the best student, or the bottom of the cranes with the worst grades, whether it is the second generation of officials or ordinary students, all of them are excited at this time.
Even the blacksmiths and carpenters that Tong Zhenye had transferred to help out at the academy stood with their arms folded and looked at their masterpieces! After all, this steam car also has their hard work in it.
"Get out of the way, get out of the way, the car is going to speed up!" Du Laoliu shouted at the crowd in front, adding coal to the stove without stopping, while laughing wildly with excitement.
"This is the first steam car since the beginning of the world, of course I have to start it! Hahahaha!"
"Fool!" Tong Lan was sitting on a rock outside the crowd, and when she heard Du Lao Liu's laughter, she pouted immediately. "This thing can't bend!"
Ren Baqian who just came over heard Tonglan's muttering, and then looked at Du Laoliu who was standing on the steam car in high spirits, and immediately showed a sympathetic expression.
You were responsible for the first accident with the first steam car since the beginning of time!
As many students got out of the way, the speed of the steam car also began to increase, and as the steam car moved forward, dirt flew around behind it.
The wheels of the steam car directly pressed two ditches in the ground.
Then the speed of the steam car began to accelerate, from the speed of a person walking to the speed of a person trotting, and it slammed into the opposite courtyard wall!
"Hey hey? How does this thing turn? Drive!" Seeing that it hit the wall, Du Laoliu remembered this. He wanted to pull the rein but couldn't find it. He shouted in a hurry, "drive" in a hurry They all shouted out, but the steam car remained unmoved and slammed into the courtyard wall.
There was a sound of bricks and stones collapsing, and the steam car hit the courtyard wall and continued to move outside.
The school is on the east side of the palace, north of Beihong district. There are few people coming and going here, only a few palace guards passing by stopped and looked at the strange thing knocked out of the school in surprise, crossed the road, Bumped towards the courtyard wall of Dazhi old Shi Qing's mansion!
The courtyard walls of Shi Qing Mansion are all made of rocks, which are much stronger than the walls of the academy. The steam car carrying the hard work of many students from the academy crashed into the courtyard wall of the Shi Qing Mansion, making a loud collision sound, and knocked out There was a small gap, but it didn't break open.
The Shifu suddenly seemed to have stabbed a hornet's nest, a dozen big and round men jumped onto the wall and stared at the assailants who dared to attack the Shifu.
The ashen-faced Du Laoliu felt as if he was being stared at by more than a dozen ferocious beasts, with cold sweat pouring out of his head, and he smiled guiltyly at the crowd: "Shi Gan made this."
While talking, he pointed behind him.
A bunch of students are running out of the gap.
"Brothers, it was an accident!" Shi Gan rushed forward to explain.
"It's the steam car we made, but something happened."
You Shi dared to explain, and everyone's eyes finally eased.
"Come back." Shi Qing waved his hand outside the wall at some point.
He looked curiously at the steam car that broke through the wall of his house: "Is this the one you are busy with these days?"
"Father!" Shi Gan greeted honestly first. Then he said a little excitedly: "This is called a steam car. It is propelled by a steam engine. It can walk without human and animal power, and it won't get tired."
"How much iron does this need!" Shi Qing's first concern was how much iron did this steel monster use, how many weapons could it make? How many soldiers are armed
Although the output of Damoshan iron ore has been a hundred times higher than before, the price of Dayao's iron ore will drop in just two years.
However, Shi Qing is not immune to the concept of decades.
"About 2,000 catties." Shi Gan whispered.
After hearing this, Shi Qing was silent for a while, and then said: "You guys are really generous!"
"Master Shi, iron will no longer limit Dayao. And these things are worth 20,000 jins of iron, not to mention 2,000 jins of iron. Just like the solar furnace back then, if you don't know how to use it, it won't be conspicuous at all. But If it is used in the right place, it will not be exchanged for ten times or a hundred times the value." Ren Baqian came from behind and laughed.
"Ren Fuzhang!" Shi Qingchao nodded: "The old man knows it, but it's just an old idea, and I can't change it for a while."
"I still remember what the governor Ren said last time, but is this really what the governor Ren said?"
"This is just a prototype, and it needs to be improved." Ren Baqian said.
"This old man doesn't understand these things, so I'll wait to see the performance of Mansion Chief Ren." Shi Qing smiled at Ren Baqian, and returned to Shi Mansion in a blink of an eye.
Afterwards, everyone carried the steam car back for inspection, only to find that the collision just now had a hole in the cylinder, and Du Lao Liu received a punch for it.
"Teacher, how can this be turned around?" Someone immediately asked Ren Baqian.
"No need to steer, just make the thing run on the rails."
Then Ren Baqian took out a few wooden sticks and showed them to everyone, and Shi Gan immediately understood. "If this is the case, the impact of the road will also be reduced, and the speed can be increased a lot."
Then he was speechless: "But how much steel does this use?"
"You don't need to worry about this. You just need to know how effective this thing is. If you can set off from Lancheng and arrive in Yunguo in three days, it will be worthwhile to consume as much iron as possible."
"Understood!" Everyone left excitedly when they heard Ren Baqian's words.
When they made such a steam car with their own hands, everyone's enthusiasm was raised. I thought that I must make the steam car that the ghost said.
Ren Baqian smiled slightly after seeing them leave.
Except for myself, I am afraid that no one knows how much steel the railway needs to consume.
If they found out, they would be frightened to death, and they would try their best to stop their idea of building a railway.
One meter of rail requires 100 kilograms of steel, and one kilometer requires 100 tons of steel.
Now, the annual output of Damoshan Iron Mine is 2 million jin, which is only 1,000 tons. It can also be used to make weapons. One year's steel can produce 100,000 steel knives, directly doubling the number of Dayao's army.
With 200,000 iron hoofs, it is not impossible to defeat Daxia.
But if you want to build a railway, don't even think about it.
From Lancheng to the border of Yun Country, it takes at least a thousand kilometers. According to the output of Damoshan Iron Mine, ten kilometers can only be laid a year, and it will take more than a hundred years to lay such a railway.
Fortunately, Ren Baqian didn't set his target on the output of the Damoshan Iron Mine at all.
Iron ore, Yunguo has it.
