There were also two hot water boilers in the materials prepared by the Executive Committee, but now they are used to build public bathrooms, and the size is too large, so there is no way to send them to the Cliff Office for installation. However, even if the Ya Office does not take the initiative to make this request, the relevant departments have already begun to develop boilers, and the executive committee instructed to build steam engines as much as possible in order to improve the production efficiency of Tiandu Iron Ore.

The world's first steam engine was used in the pumping operation of mines, and then gradually spread to smelting, textile and machinery manufacturing industries with the continuous improvement of steam engine technology. As for being used as propulsion power, it was a hundred years after the invention of the steam engine. At present, the pumping operation in Tiandu iron ore mining is more dependent on water pumps to complete, and every time several large water pumps are started, the civil electricity of the entire No. 2 base has to be stopped to ensure the production of electricity, which naturally causes a lot of inconvenience. There have long been calls from the people for the Executive Committee to launch the steam engine project to free up the limited electricity for the people.

From the moment the traversal came to this time and space, the invention time of the steam engine was more than sixty years earlier than in history. As for the parts of the steam engine, such as the split condenser, planetary gear, parallel motion linkage mechanism, centrifugal governor, etc., which were invented one after another, they will appear in the world more than 100 years earlier than the original time.

Now that the Tiandu iron ore mine was already being mined, it could provide enough pig iron for the manufacture of steam engines, and the machining department could also complete some simple metal processing tasks, so the executive committee, which did not want to wait any longer, ordered the development of the steam engine to begin. Of course, the Executive Committee was counting on not only a power unit for pumping water, but more importantly a steam engine that could be used as a propulsion power.

There are quite a few people in the executive committee, and even some high-ranking people in the executive committee have made it clear in private that they appreciate the party. In order to achieve the rugged and heroic mechanical beauty, the powerful steam engine is absolutely indispensable. However, to produce steam engines under existing conditions, technical obstacles were inevitably encountered in some key processes.

Welding problem is only one of them, for the solution of welding, the relevant departments have already had a detailed plan before the crossing, and the riveting word is the best way to solve this problem. Roger and Shi Diwen, two returnee senior fitters, once again came in handy and solved the problem of boiler manufacturing with the riveting process. Although the sealing performance of this relatively primitive process is not as good as welding, it is sufficient to deal with the non-high-pressure boiler used in the primary steam engine built today.

At present, most of the machining equipment has not been installed in place, and many parts on the steam engine have to be built by technicians, especially pistons, valves, gears and other parts, which consumes a lot of man-hours. The first steam engine took more than 20 days from the drawing to the assembly. And tonight will be the test run of this steam engine, Schneider brought Luo Shengdong here, also to let him see the great power of steam power.

Luo Shengdong looked at the scene in front of him, and his mind was already a little confused, on the huge platform was placed a complex device made of pig iron, on the right was a huge iron wheel nearly one person high, this iron wheel only had a few thick spokes, and several iron rods connected to the spokes connected it to the iron can at the other end, and next to this iron can lay a larger iron bucket, and there was a prosperous charcoal fire underneath.

Luo Shengdong looked around, and saw that many of the leaders of the Haihan people he knew had already arrived, and knew that this thing in front of him must be something amazing, so he immediately lowered his voice and asked Schneider: "Mr. Shi, can you tell me, what is this?"

"This is the steam engine, the world's greatest invention for hundreds of years. Schneider stared at the steam engine that gradually emitted white smoke from the chimney, and said slowly: "Look at it, this is the power that can change the world!"

Luo Shengdong said in his heart, if you create a giant cannon that can collapse mountains and split cities, or there are mountains of gold and silver, I believe that you have the power to change the world, but with such a black iron bump, you can also change the world? Is it really that Lao Tzu was bluffed since he was a child? Fighting for chicken? It sounds a little familiar, I don't know what it has to do with the kind of "starting chicken" that Ren Liang said?

None of the traversers present cared about Luo Shengdong's careful thoughts, and their attention was all on this steam engine. With steam power, the productivity of the entire crossing group will be greatly improved, and the pumping machines, lifting equipment, forging presses and even steam locomotives driven by steam engines will greatly accelerate the pace of changing the world through the world, and the future steam-powered fleet across the seven seas seems to be no longer out of reach.

"Let's start!" Tao Donglai gave the order, and at the same time said a bloody line that was widely circulated in later generations: "Let the whole world tremble in front of our steam engine!"

Roger, who was in charge of operating the steam engine, opened the steam valve, and a thick puff of steamy white smoke rushed out of the chimney. Driven by steam, the piston in the cylinder slowly but firmly began to move, and then the connecting rod drove the spokes of the huge iron wheel, pushing the iron wheel from slow to fast to start spinning.

"It's a success!" The technicians who had been fighting for many days excitedly clapped and hugged to celebrate this moment of victory, and the members of the executive committee also expressed their joy with warm applause.

"This ......" Luo Shengdong was already dumbfounded, and was so frightened that he couldn't speak. This iron wheel is only afraid that it weighs more than 1,000 catties, and there is no one to push it left and right, how can it turn on its own?

"It's moving, it's moving, it's moving!"

Schneider excitedly grabbed Luo Shengdong's shoulder and shook it again and again, but it made Luo Shengdong recover a little bit of sanity, and hurriedly asked: "Mr. Shi, why can this thing be automatic without wind? Could it be some kind of advanced spell?"

Schneider laughed and said, "Spells, no, it's not spells, it's science!"

"I'm stupid, I've only heard of Confucianism and Taoism, who created this science? Also, what kind of chicken is this angry chicken?" Luo Shengdong couldn't help the curiosity in his heart, and asked Schneider again and again.

Schneider patiently explains: "The steam engine is not a chicken, it is a mechanical device powered by steam, just like the one you see in front of you." As for science, this is a way to pursue knowledge and understand the world, and it is a belief that every Haihan person will abide by!"

Luo Shengdong heard it in a fog, and he probably understood only the word "faith": "I see, this science must be the state religion of the Haihan Kingdom!"

Schneider pointed to the rotating big iron wheel and said, "Isn't it exciting to have a machine that doesn't need to be driven by human and animal power?"

Luo Shengdong scratched his head and said, "But what's the use of creating this thing?"

Schneider looked at Luo Shengdong like a monster: "Mr. Luo, I thought you were a person with a rich imagination and a quick acceptance of new things, so I took you to see the steam engine, I didn't expect your mind to be so imprisoned." With four wheels, it can move around on land on its own, and with the paddles, it can propel the boat instead of the wind, and with rigging, it can pull a thousand pounds...... What's the use of it, you're asking?"

Luo Shengdong suddenly remembered the big iron ships in the harbor of Shengli Harbor, and stammered: "Those iron ships are ...... That's what you use?"

"It's better on board than the one we've built now. Schneider doesn't intend to hide anything, this kind of black technology that spans the times can't be copied even if Luo Shengdong sees it with his own eyes: "Our current manufacturing level is still very limited, and we can't make such good things for the time being." But it's enough to be able to build this kind of thing, Mr. Luo, to see the birth of the world's first steam engine with your own eyes, and when you are old, you will have a cowhide to blow with your grandchildren. ”

It wasn't until now that Luo Shengdong understood what he was seeing. Isn't the "steam engine" Schneider talking about just a stupid big black crude version of the "engine"? The big iron ships in the harbor and the strange cars that carry stones are all high-end scaled-down versions of this thing.

Luo Shengdong has long felt very strange that the Haihan people have such technology as "engines", why don't they manufacture these powerful mechanical devices on a large scale, but instead need to use a large number of manpower in various construction projects to supplement the lack of mechanical devices. Now seeing this rattling iron bump, Luo Shengdong understands that it is not that the Haihan people do not want to use mechanical devices on a large scale, but because they have not been able to build them before!

Now that the Haihan people have finally created this kind of device, Luo Shengdong sadly found that the gap between the Ming Dynasty and these Haihan people seems to be even greater. Thinking that there would be countless strange ships driven by this device across the sea in the future, Luo Shengdong felt more and more that it was really boring for him to be a sailor. One such machine can replace twenty or thirty people to lift and lower the sails, and these saved crews can be used to operate the iron cannons that the Haihan people claim to carry on board. Although he hadn't seen the real thing yet, Luo Shengdong felt that the kind of powerful battleship full of artillery that Tao Donglai had mentioned might really appear in the future Victory Harbor.

"Why can my Daming's charcoal fire only be used to cook and cook, but the Haihan people can use it to build this powerful steam engine!" Luo Shengdong was very upset about this, at this moment, he seemed to feel the deep malice that God did not hide for Daming.
