Everyone followed Zhu Yuan's gesture and turned their eyes together.

Seeing a group of steam engine ships slowly cruising in the lake, they didn't even need Zhu Yuan to explain more, and everyone had already begun to sketch in their minds what the scene would be when these ships were magnified a hundred times and a thousand times.

Zhu Yuan waited patiently for a while this time, allowing everyone to watch or whisper.

After a while, Zhu Yuan opened the next page of the demo board 'ppt', and clapped his hands again to recall everyone's attention: "So, let's talk about the principle first, steam engine ships, like steam trains, also use steam power, and their power cores are steam engines. However, the steam engine is only equivalent to a heart, and in the future, if we want to truly achieve diversified control, we also need to develop the transmission system, braking system and other architectures, because the direction is determined, I still just said, this is only a matter of time. ”

As he spoke, he turned another page: "When it comes to steam engine ships, what I want to emphasize is two points, one load and one speed. Oh, I suddenly remembered the power I just talked about with my ancestors, or, load and speed, can also be called 'power' and 'efficiency', just like the excavator just now, which can dig 500 catties of soil at a time, that is called power, if it can dig 10,000 times a day, this is called efficiency. Power and efficiency go hand in hand. If an excavator can dig 500 pounds of soil at a time, and can only dig once a day, then the machine is meaningless. Similarly, if an excavator can only dig 1 pound of soil at a time, it makes no sense to dig 10,000 times a day. Steam engine ships, too. ”

"Let's talk about the load first, or in 'tons', here I'm promoting, 1 ton is equal to 1,000 catties."

Regarding 'ton', Zhu Yuan has long remembered it.

Today is an impression for everyone.

As for the foreign nature of this unit of weight, it doesn't matter.

Although he is a nationalist in his bones, Zhu Yuan is not narrow-minded, not only that, but Zhu Yuan also very much admires the set in the bones of Westerners: what is yours is mine, and what is mine is still mine.

It's like a museum.

Grab all your things and put them in my museum, that is, diversified, world-class museum. On the contrary, you only have your own things in the museum, and if you lack diversity, you can't compare with ours.

Zhu Yuan felt that this was right.

This time, since there is an opportunity, this is Zhu Yuan's goal.

In the future, wherever the Ming Iron Horse goes, your land, gold, and women will be mine!

What a good reason.

As for what civilization, what barbarism?

You step on someone else, you say whoever is civilized is civilized, you say whoever is barbaric, who is barbaric.

If it's the one who gets stepped on.

Tut.

numbness, ignorance, backwardness...... Otherwise, why are you at my feet?

Look!

What a smooth logic!

So, remember!

On top of these fundamentals, no matter how many high-sounding they are, they are all nonsense.

Let's talk 'ton' again.

Of course, 1 ton was 2,000 catties, but Zhu Yuan didn't plan to introduce the original version so awkwardly, he needed a simpler decimal system.

Therefore, not only is 1 ton equal to 1,000 catties, Zhu Yuan also hopes to carry out a comprehensive decimal specification for 'stone' or 'dan', as well as the current 1 catty equal to 16 taels, and even various other units of measurement.

The kind that Qin Shi Huang made.

Inside the garden of the present.

Re-emphasizing the new weight unit he wanted to promote, Zhu Yuan continued: "The largest ship we have at the moment, a 5,000-material sea vessel, without considering the risk, can hold 50,000 stone of grain at the limit, plus the crew and water, etc., its load, according to the 'ton' I just said, is about 10,000 tons." This is already huge. However, this is far from enough for the vastness of our oceans. In the future steam era, or later, the Ming Dynasty should build a 100,000-ton or even 1 million-ton ship, so that a ship on the sea is equivalent to a sea city, if it is a warship, then it is a movable offensive and defensive city. ”

Pausing again, to give everyone room to fantasize, Zhu Yuan continued: "Maybe some people are wondering, do we need such a big ship? A: Yes, of course. ”

Speaking of some depictions on the demonstration board: "Super-loaded vessels, on the one hand, can be used for fishing, and moreover, not only fishing, a boat, can also load the entire industrial chain on it, from fishing to processing, and even carry out peripheral aquaculture, and the advantage of this is that the ship does not have to dock frequently during the fishing season, and at the same time, it can also be without worrying about the supply ground sailing to the deep sea." Here, I also said that the world map just now, our current sea fishing area is only two or three hundred miles offshore, and the depth of the sea is often thousands of miles, if you want to obtain deep-sea resources, it is necessary to be able to meet the needs of super-large ships that do not have to dock for several months at a time. ”

After saying this, Zhu Yuan followed the point to the next: "Let's talk about shipping, you can imagine a picture again, in the future, a 200,000-ton cargo ship will transport 1 million grains south of Shijiang to the north where there is a long-term shortage of grain in three days, what will be the scene?" Moreover, when the ship arrives in the north, it will not return empty, and we can also transport the timber, minerals and other resources from the north to the south. This goes back to the section on the railway, the "distribution" of "regional resource allocation" in the "science of economics". Traditional sea freight, because the carrying capacity is relatively small, the cost is actually very high. Like the pre-meta data I've studied. In the Yuan Dynasty, a stone worth 1 tael of grain in the south was transported to the north, and the various costs added up, the price was at least tripled, and our current transportation, the comprehensive cost, is actually not low. If it can realize the transportation of super-large capacity sea vessels, relatively speaking, because of the close distance, the transportation cost can be almost diluted to negligible, and the grain of 1 tael of silver and one stone in the south is basically 1 tael of silver and one stone in the north. Oh, this is an advance reminder, if you want to do some food business to subsidize your family in the future, I think it's okay. ”

Everyone laughed cooperatively, and even Lao Zhu grinned.

Zhu Yuan quickly continued: "Let's talk about speed. At present, our sea transport route, Mingzhou to Zhigu, about 3,000 miles away, traditional sailing boats, even if the road is smooth, often take ten years to arrive, if the wind direction is not right, it may take up to one or two months. Now, the steam engine ship will not only break through the load limit, but the most important thing is that it can break through the speed limit, and can make our shipping no longer be controlled by natural factors such as ocean currents and monsoons. One of my more preliminary assumptions is that, like the steam train, the steam engine ship must at least reach a distance of thousands of miles a day. Then, 3,000 miles of sea transportation, when the time comes, it will only take three days. Considering the relevant load, this will completely solve the problem of 'regional resource allocation' between the north and south of the Ming Dynasty. ”

When Zhu Yuan said this, the scene was full of contemplation.

Many people have thought of the three 'tens' when Zhu Yuan talked about the 'steam train' just now.

100,000 troops, 100,000 grains and grass, arrived in 10 days!

This steamer...... It is conceivable that I am afraid that the first two 'tens' will be replaced by the word 'hundred'.

Moreover, Zhu Yuan did not say that steamships can only travel on the sea.

The land canals are obviously navigable.

Thinking of these, even though they had been amazed more than once in their hearts, everyone couldn't help but sigh again.

The future!

After a while, Zhu Yuan opened another page of 'ppt' and said with a smile: "Everyone must have added many uses of steamships in their hearts, and here, I will continue to talk about some of my thoughts." First of all, about sea trade. ”

said the content of the 'ppt' in front of him: "Traditional maritime trade, everyone's impression is all kinds of valuables, spices, ivory, tortoiseshell, etc., why are general materials rarely traded at sea?" There are also many reasons, but I will only say that in relation to today, the cost of transportation. As I just said, if 1 stone of grain is transported from the south to the north, the price is almost unchanged, which is actually equivalent to saving the transportation cost equivalent to several times the value of the grain itself. At the moment, this part of the cost cannot be saved, and it is very expensive, because the sea route is too far and dangerous, and you can transport a shipload of grain from China to the South Seas, which is a fool's doing. However, if the age of steam with very large loads of ships arrives, general commodities, such as grain, timber, minerals, etc., will also join the maritime trade. ”

After another pause, Zhu Yuan said: "You may think, even if certain conditions are realized, is it profitable to do these businesses, or even, is it meaningful?" Of course there is, all of them, and, very importantly. ”

When Zhu Yuan said this, the thinking of the ministers had not kept up, and Lao Zhu had already thought of it.

The way of man is to lose more than enough.

Zhu Yuan also replied: "Because these things are necessary for people's livelihood." What is the 'people's livelihood', and the livelihood of the people. Our Ming Dynasty has laid down the world, and if we want to govern the world in the future, it is just two words, 'raising the people', if the people have nothing to support, repeat the mistakes of the Yuan, but it will be a moment. How to 'raise the people', the topic is still too big, and it is still said to be related to today. When we can make a super-large capacity steam engine ship, then we can use our highly valuable ceramics, silk, tea, etc., to transport overseas, and then exchange for all kinds of people's biological resources overseas, such as grain, timber and minerals, which are of very low value but huge overseas, and so on. ”

After a pause again, Zhu Yuan continued: "This is only the first stage. As you can see, the ships in the lake are not only all kinds of cargo ships and passenger ships, but also warships, which are not used to watch, but to continue to fight the world. What we have to do is not only to completely divide the sea that we can reach into the territory of the Ming Dynasty and completely occupy such a 'fertile field', but also to all the land that our Ming warships can reach in the future. At that time, trade is no longer needed, and the Ming Dynasty only needs to transport all kinds of bulk civilian materials from overseas territories to the country, then, under the sufficient material security, the people of the Ming Dynasty will no longer have to worry about hunger and cold. ”

Speaking of this, Zhu Yuan swept around: "Everyone, do you remember what I promised to my ancestors to 'send five hundred years of national honor'?" ”

Quiet again!

Zhu Yuan didn't wait for everyone to answer, and already said loudly: "As long as I realize what I just described, the five hundred years of national glory, how can it be enough?!" ”
