"What do you bring? Bring forth...... Civilization?! In the mansion, the noise of the steam engine made everyone shout as hard as they could, and Xiong Jing listened to Zhao Huang's proclamation, and said without looking back: "Bird Ming." Missing. ”

After throwing out these words, he once again discussed with Gong Yindao, Ou Chou and others about the watt steam engine in front of him that was emitting white steam. The steam engine was on and off, and every time the piston stopped, the white high-pressure steam in the boiler came out, turning the entire shed into a fairyland.

Although there are already huge steels with various carbon contents, although there are high-strength cutting tools, although there are high-precision boring machines, although there are ......, Kezaofu still can't make a stable performance of the watt steam engine.

In fact, Zaofu only used a boring machine to boring out the high-precision cylinder of the Watt steam engine, thus solving the cylinder leakage problem of the Newcastlemen steam engine. The Watt steam engine is balanced, because the cylinder accuracy is sufficient, and the piston is wrapped with hemp rope enough to seal the cylinder, and the Newcammen steam engine can only be placed vertically, because there is a thin layer of water at the upper end of the piston, which is the key to sealing the cylinder.

No one thought of a method of sealing with water, and according to Xiong Jing's guidance, he made great efforts to build a boring machine, and boring out a cylinder that could be directly closed with hemp rope, but what to do next Xiong Jing is not very clear. The Watt steam engine can do work back and forth from side to side, and its structure includes air valves, crankshafts, connecting bars, and flywheels, compared with the Newcastlemen steam engine, which is too simple to be simple, the Watt steam engine is too complex, and the speed of the two is also very different.

The piston speed of the steam engine was increased from four round-trips per minute to 10 times per minute, and then to 16 cycles. By the end of the eighteenth century, Watt had made the piston of the steam engine fifty round-trips per minute after twenty years of improvement. The faster the speed, the higher the mechanical strength requirements, the lower the design fault tolerance, and the more accidents.

The mechanical design and machining of the house can't keep up at all. There are a variety of machine tools, but they are only a little better than hand tools. All of these machine tools do not have variable speed gear speed regulation, so there is only one fixed speed; There are not many fixtures, and the machining accuracy is difficult to guarantee. Stress calculations, strength calculations, there is no such thing as a stress calculation. How thick the connecting rod of the steam engine needs to be can only be estimated according to experience, and it can be replaced with a thicker one if it is broken, and then replaced with a thicker one.

Xiong Jing was also helpless about this. He has seen the limits of the craftsman who built the house, and he also knows his limits. That's all he knows, and if the craftsmen who build the mansion want to completely change the watt steam engine, it is estimated that they will have to wait for the next generation of craftsmen with complete education to grow up, and only they can completely improve the steam engine and improve the boiler.

As they spoke, the craftsman opened the cylinder intake valve again, and steam poured into the cylinder. At this time, the piston began to do lateral reciprocating motion, and the speed was getting faster and faster, but there was some slight flutter in the rotation of the flywheel rotating at high speed at the other end of the connecting rod, and the amplitude of this flutter was getting bigger and bigger. Stop!! ”

He shouted to stop, but the cylinder connecting rod had already cracked from the flywheel with a 'dang', and a small piece of steel shredded happened to pass over Xiong Jing's head, Xiong Jing's face did not change at that time, and only then did it turn pale.

"The villain is a capital offense!" The face of the craftsman who opened the air intake valve was whiter than Xiong Jing's, and he fell to the ground in a hurry, and his head was stunned.

"Death penalty!" Gong Yindao, Ou Chou and others also hurriedly fell to the ground, and they were glad that Xiong Jing was safe.

"The steam engine that can kill is not yet built, so why panic." Although Xiong Jing, who was almost killed just now, was afraid in his heart, he still reluctantly laughed and said, "You are innocent, get up." ”

"King Xie." Gong Yindao looked up and saw Xiong Jing with a smile on his face, so he got up from the ground.

"I don't believe you'll be able to build it one day." Xiong Jing looked at the craftsmen who were still in a hurry, but no one dared to answer.

This is not a big-winged warship or a sail boat, but a large-wing warboat and a sail boat are just building the palace on the water, and there is no change in the nature of the wood, the structure of the columns and beams, and the principle of construction. The steam engine is different, the nature of the iron is not yet fully grasped by the craftsman, the mechanical structure and the results of the columns and beams are also very different, and the most important thing is the movement.

No matter how fast the speed of the large-wing warship is, it is only the bottom of the boat gliding on the water, the inside of the boat is completely stationary, and although the steam engine is fixed on the ground, every part of it is moving. Not only is it moving, but it is also terrifyingly fast, faster than the high-speed galloping cars on the battlefield. None of the moving parts can go wrong, and these parts must be in motion for at least eight hours a day, or at least three hundred days a year. If this strength is a truck, it will not be scrapped in a month.

"What, can't you make it?" Xiong Jing saw that the craftsman did not agree, and he couldn't help but be a little disappointed.

"The villain doesn't dare to deceive the king." One of the craftsmen lowered his head slightly, and quickly lowered it again.

"Gong Yin Dao," Xiong Jing turned to Gong Yin Dao.

"The minister is here." Gong Yin Dao didn't know what Xiong Jing was going to do, and he was very uneasy.

"From today onwards, some students who are smart and good at making tools will be selected from the school to practice in the house." Xiong Jing can only hope for the society.

"Respectfully obeyed." Gong Yin Dao said, he breathed a sigh of relief.

"The mansions still use the previous steam engine, and this type is recovered." Xiong Jing said again.

Imitation Watt steam engine accidents continued, so the Newcastlemen steam engine had to be used back. The difference between the two lies in the work done and the coal consumption. A Watt-like steam engine does twice as much work as Newcastlemen, but consumes two-thirds of the coal. This is a difficulty that can be overcome, but it is just one more steam engine and an extra half a ton of coal per day.

Now most of the motivation for building the house has been changed to steam engines, especially the cement factory. The cement output is 100,000 tons per year, and the cement raw clinker must be grinded, and the 400,000 tons of raw clinker need 150 steel mills driven by steam engines to grind day and night, and there are more than 100 crushers. Switching to a Newcastle steam engine would increase coal consumption by more than 50,000 tons a year.

But there is no way to do it, if you don't replace the original steam engine with stable performance, equipment failures continue to delay production, cement supply is insufficient, and the defense lines of various countries cannot be completed within the planned time, which is a big problem. Huainan Coal Mine is on the side, using a steam engine to pump water, a steam engine to fill air, and a steam engine to lift coal from the ground, and the coal mine efficiency is twice as high as before.

Of course, Gong Yin Dao knew the importance of this, and he also wanted to suggest it when he took Xiong Jing to see the steam engine. After the four kingdoms consulted, the three kingdoms of Wei, Qi and Zhao all urgently needed hundreds of thousands of tons of cement to build additional city wall fortifications. According to their plan, the cement needed was millions of tons, which was obviously impossible, and the government was very careful to increase the production scale by 150,000 tons, and achieved it within three years.

"Sulphur geometry?" Xiong Jing, who left the workshop with regret, asked about the sulfur, and everyone valued the sweat and blood brought by the Sogdians, but he only valued the sulfur brought by the Sogdians.

"The Hu people have shipped a lot this time, more than ten times more than before." Gong Yin Daodao.

"How many tons?" Xiong Jing's heart jumped, and he asked directly about the quantity. If there are three or four tons......

"According to Hu Shang's report, there are four or five tons." The caravan has entered the city, and the goods have been counted and are now in storage. Gong Yin Dao recalled his subordinates' report and said the approximate number.

"Good." There was more sulfur than expected, and Xiong Jing couldn't help but be a little happy. Only then did he remember what Zhao Huang had just reported, that the envoy of Bactria was going to see him now, saying that he had brought some civilization.

This attitude disgusted him. People are not changed by monkeys everywhere, people run out of Africa, and the reason why they reproduce and develop differently is because of their different geographical locations. The difference in geography creates a difference between East and West. Only after entering the industrial revolution did the West truly lead the world. The reason for this is only geography.

The North Sea, surrounded by the islands of Great Britain, the Shetland Islands, Scandinavia, Jutland and the Western European continent, is the middle school of great navigation. In these seas, the Vikings invented isodimensional sailing and created ships that were more resistant to wind and waves, and these experiences were combined with Mediterranean seafaring technology and tradition to produce everything needed for great voyages.

There is no nautical school formed by geography in Asia, and not only is there not, but there is a 'big gully' to prevent boats that have not mastered the technology of tuning from going east. The distance between the Americas and Europe and Asia, as well as the topography of the Americas themselves, also determined that Europe was easy to discover and immigrate to the Americas. From Europe, it only takes 27 days to cross the Atlantic Ocean with a tailwind, and most of the landings are rich areas, and you can easily reach the Great Lakes region; It's a different story in Asia, where it takes at least four months to cross the Pacific Ocean downwind and see the Rocky Mountains when you come ashore.

The grand question of civilization is not something that Xiong Jing can understand, and judging from the great voyages he is familiar with, it is the geographical differences between the East and the West that have caused the result of being controlled by others in later generations.

As for the difference between Alexander's army and the Persian army, it was not so much a difference in military technology as a difference in organization. It is well known that in the Battle of Gaugamela, the Persian Emperor Darius fled and caused the collapse of his army, and Alexander destroyed the Persian Empire in World War I. In fact, in the Battle of Issus, two years before the Battle of Gaugamela, Darius also fled; In the previous battle of Granicas, the Persian infantry suddenly fled, leaving 20,000 Greek mercenaries still holding their positions.

Weapons and tactics are indeed important, but it is people who use weapons and complete tactics. If there is no trust between soldiers and soldiers, and there is no deep affection for robes, when you calculate me and I beware of you in battle, you want to run in front by yourself and others stay behind, no matter how good the weapons and equipment are, you will lose in every battle.

On the way back to the palace, Xiong Jing remembered the Greeks and the battles that Wu Ji described. He didn't take the words of the Bactrian envoy to heart, he just understood them again.
