Huo Gang's words made Lu Mu and them all stunned slightly, and several people immediately thought about it, but Lu Mu quickly spoke: "This ...... We haven't thought of it yet, but the leader said so, this is indeed feasible, but the terrain is quite restrictive for this kind of vehicle, but for the time being, it shouldn't be too much of a problem for us. However, the requirements for the foundation of the road are relatively high. ”

"Well, I'm not asking you to make it right away, but you can develop it now, because it's going to be made sooner or later, and our first five-year plan is to try to make it happen." Huo Gang said with a smile.

"Yes!" Lu Mu and the others immediately arched their hands.

To be honest, if it weren't for the speed of the improvement of the steam engine, Huo Gang actually didn't want to get the train out so early, but now, if the train is out, of course, the bonus to them is very large, and the appearance of the train means Huo Gang is very clear, which means that a centralized empire has control over a country.

Even if the speed of the steam train is not fast, about 40 kilometers per hour, or even faster than that of a horse, of course, this is also in the case of carrying certain supplies, but its huge carrier, and its continuous operation, means that a train can continue to move forward every day.

24 hours a day meant that it could travel nearly 1,000 kilometers a day, and the steam trains, although not as many goods as later trains, had no problem transporting thousands of people at a time.

The most important thing is that the speed of this thing is too fast, a thousand kilometers a day, in this era, only 800 miles can be expedited, but 800 miles can not be done at such a speed for the entire army, and the man has long died.

Therefore, the emergence of the train means that the territory of the rule can be expanded, if the Han Dynasty and the like have trains, it is estimated that the Turks have long been gone, and the steppe cannot be like today.

It's far away, even Huo Gang and they don't know when the train will be made now.

"Chief, then we'll start casting tests on the steam engine right away, but Chief, I still have a doubt." Lu Mu next to him asked.

"You say."

"We have read all the books you showed us before, and they say that the atmosphere is pressurized, and if the altitude is higher, the lower the pressure, and the thinner the air will be." Rumu repeated the contents of the book.

"Yes." Huo Gang nodded.

"As you showed us before, steam-driven wooden stoppers can even break through brick walls, because there is too much steam heated in the iron pipe, which causes the pressure inside to continue to rise, right?" Lu Mu asked.

"Yes." Huo Gang is still very satisfied with their level of learning, to be honest, their learning almost relies on them to learn by themselves, although Huo Gang has explained some things to them, but Huo Gang really doesn't have that much time, that is, some important ones to explain to them, or to explain to their own maids, and then they go to ask Chunmei and the like.

More time, they rely on the textbooks provided by Huo Gang to learn by themselves, fortunately, Huo Gang has read the textbooks, it is really an introductory, that is, starting from the composition of the whole world and so on.

So as long as they look at it with their hearts, put aside their previous prejudices about the world, etc., they can indeed learn by themselves, of course, this depends on their ability to understand.

If they can't understand it, ask Huo Gang again.

"Chief, we read the textbook before, everything in the world has some small balls...... That is, atoms are made up, and atoms are made up of many smaller particles, this ...... It's a little hard for us to understand, but the books say that the higher the temperature, the faster these particles move and the more energy they can release. ”

"So we thought, if we put pressure on it with this water vapor and don't let it evaporate and release it, just like it was in the iron pipe before, and then release it to impact the piston when it reaches a certain level, can we make the piston move faster, or push a bigger piston, and it can send out more power?" Lu Mu asked.

"I ......" Huo Gang almost said the word "" directly, but Huo Gang looked at Lu Mu and Lu Feng, who were listening to the lecture with peace of mind, Huo Gang had to say, these people ...... It's really perverted.

Even the high-temperature steam and superheated steam are about to come out? If you are allowed to continue, this is the principle of large industrial steam turbines! Steam turbines are powered by high-temperature, high-pressure steam, which has been the case for all large ships in later generations, including nuclear power.

Because nuclear power can't help the fate of boiling water.

The problem is that Lu Mu didn't know the principle at all, they just based on these descriptions, and then added their own guesses, and directly began to derive the results...... This is typical of traditional craftsman thinking.

In fact, some craftsmen in ancient China, when they taught their apprentices their own unique skills, many times, because these craftsmen themselves did not understand the principle of their unique skills, they were more likely to summarize this principle through countless applications, but they did not know the specific principle.

So they began to use this stupid method to teach their apprentices, which is also the reason why many unique skills in ancient times were lost, because this stupid method of teaching apprentices requires apprentices to understand, if they can't comprehend, they really can't comprehend.

Because you don't know the principle, you want to understand it, and sometimes, it's really difficult.

It's like you don't know the principle of the Pythagorean theorem, but you know that the data for this type of triangle of this length must be like this. Then you can only make triangles for this length, but if you know the principle of the theorem, then you can apply it to different right triangles.

Huo Gang is not talking nonsense, he is telling the truth, because these craftsmen in ancient times, there are a lot of illiterate craftsmen, and many illiterate craftsmen have a lot of unique skills in their hands, so you can imagine the difficulty they have to learn these things.

This is also why in ancient times there was a saying that one day is a teacher and a father for life, because the apprentices at this time are really old in the master's parents for many years after they have recognized the master since they were young, and they will always follow the master to learn.

This is also why, the two acts of deceiving teachers and destroying ancestors are almost the same.

"You're right, you're really good, it's not just steam, you all know the Kong Ming lantern, right?" Huo Gang looked at them and said.

"Yes." Everyone nodded immediately.

"So, in fact, air also has the same effect as water vapor, if you can seal the burning air in a certain space and let it burn quickly, the hot air brought by the burning air will also have a similar effect to water vapor. It is possible to push the pistons, but we don't have enough fuel for that at the moment. Huo Gang said seriously.

He doesn't mind telling these people about this knowledge, as for what knowledge should be learned first and what knowledge should be learned later, it! Huo just didn't care so much, the main thing was that Huo Gang didn't know either! In later generations, the textbooks he studied were summarized by countless people, and in this era, Huo Gang could only remember what to teach, how did he know what to learn first?

So what these craftsmen can learn, let them play, in fact, what they learn is extremely limited, what Huo Gang really expects is the current group of children who have started to learn modern science, these craftsmen's children, they are the real future.

But Huo Gang also had to admit that under the stimulation of writing books and biography for them, the learning ability of these craftsmen was beyond Huo Gang's imagination.

Just like many young people in later generations ridiculed, if in reality it is as proficient as a game, and if you can clearly see the results of progress with hard work, it is estimated that everyone will have some unique skills under their hands.

Although this is a joke, it has to be said that it actually has some truth.

"But you don't have to be too ambitious about these things, just like a steam engine, its research and development will never end, you can continue to develop more advanced steam engines, for example, make it smaller in size, but the output power is higher, etc., but you can't set the goal too high at one time."

"Don't forget, your most important task is to use these steam engines in our different industries, to improve them so that they can assist in grinding cement, calcining cement, and so on."

"Only by liberating more people to come out, our production speed will be faster, and our territory will be richer, just like the silk we spin, we can be 10 times faster than Datang in the same time, which means that our labor cost is only one-tenth of theirs, and the final cost of the cloth we make may only be one-third of theirs."

"If this kind of cloth is on the market, will everyone buy us? When everyone buys us, are we richer? ”

"When we have the money, we can buy more things so that you can develop more advanced technology, understand?"

"Follow the instructions of the chief." All the craftsmen in the room bent down in unison and replied.

"Yes, Lu Feng." Huo Gang nodded and didn't continue, but said to Lu Feng, "Do you have a suitable craftsman here who knows how to identify minerals?" ”

"Chief, I know a little bit about identifying minerals, but there aren't many other people in this area." Lu Feng shook his head.

"You can't do it, you still have to improve the steam engine with Lu Mu, the steam engine is more important, so let's find a few people who have a preliminary understanding of prospecting, let him form a team, I have some important things for him to do." Huo Gang thought for a while and said.

"Yes!"
