"This first point, the water tank is too troublesome to build, and it is difficult to build too big, if there is a way to bond the steel plates, and can withstand relatively high temperatures." There is no electricity, so naturally let alone electric welding, Zhang You himself didn't know how to solve this problem, but he still said it.

Brainstorm in case you find a good solution.

The three of them nodded again and again, and Guo Zaoqing said: "You are right, this is the biggest shortcoming of this thing, if you can really find a perfect and simple bonding method as you said, the cost will be reduced all of a sudden, and it will naturally be easy to popularize." ”

Zhao Shizhen asked: "What about the second point?" ”

Xu Guangqi is a lot more cheerful than before, but he still doesn't like to talk much, but his demeanor is very focused, he knows Zhang You too well, he is extremely smart, and his whimsical ideas are endless, if there is still a person in this world who makes him admire, it is definitely Zhang You.

For Zhang You's suggestion, he didn't dare to be careless, and paid full attention, for fear of missing a word.

"Second," Zhang You stretched out two fingers and shook it: "It's too troublesome to open the plug and put it on, it's best to let the piston complete this set of actions by yourself when it moves, such as ......" He stopped, searching his stomach and stomach, wanting to recall the knowledge of this in later generations.

Seeing that he suddenly fell into deep thought, everyone didn't dare to disturb, looking at him quietly, Xu Guangqi even sweated nervously.

Maybe it was luck, or maybe it was everyone's pious trust that moved the heavens, Zhang You's mind suddenly popped up with a word single-action cylinder, and then slapped his head, and said excitedly: "Why didn't you think of it earlier, you can use a spring!" ”

"Spring?" Guo Zaoqing repeated, but Zhao Zhenyu behind everyone was like an initiation, and shouted in surprise: "I understand, I understand, it's so simple, why can't I think of it?" "There are springs on the wheelchairs, so everyone knows what they are.

Everyone was so focused that they didn't even hear when he came in, they were startled by his voice, and they turned around one after another, Zhang You couldn't help but be surprised, and asked, "Do you really figure it out?" If you figure it out, I'll tell you about it carefully, and I've heard that what you say is as different as I thought. ”

"It's very simple," Zhao Zhenyu at this moment has long since lost the shyness when he was joking with Zhang You just now, like a confident king, walked to the side of the piston and pointed to the piston and said: "According to your reminder, my lord, I suddenly thought that I only need to install a strong spring inside one end of this iron pipe, and then make an opening here, when the hot gas pushes the internal plug to move to this end, when it reaches this opening, the gas is discharged, and the spring that is just compressed has an effect to push the plug back into place, The process is repeated by recharging the plug after a portion of the hot air has been drained, pushing the plug to this end again, so that not only does it not need to open and close the cork on the tank as often, but also adjusts the size of the vent to reduce the risk of the tank exploding due to too much pressure. ”

He pointed and explained at the same time, and said it clearly and clearly, even the traveler next to him understood what he meant, and after he stopped, he looked at Zhang You with Guo Zaoqing and others, wanting to hear what he had to say.

Zhao Zhenyu also woke up from a certain frenzy at this moment, regained his shyness, looked at Zhang You with some embarrassment, and said: "My lord, I don't know if it's good to say it......

"Well, how bad, it's just great!" Zhang You couldn't help but pat Zhao Zhenyu on the shoulder, and said approvingly: "No wonder my husband is so protective of you, you are really a rare talent, it is very good, even more comprehensive than I thought, I think you will not be in the firearms department next, and you will be responsible for the study of this heater...... What do you think, sir? ”

The latter sentence was asked to Guo Zaoqing, and Guo Zaoqing smiled: "Of course you can, but he can't completely leave it on the side of the Firearms Division, and he has to go over to help when he needs it." ”

"Of course, I'll talk to Your Majesty about it when I go back, set up a department to specialize in research and development of heaters, and Zhao Zhenyu will be the head of this department, how about Xiao Zhao?"

Zhang You asked Zhao Zhenyu with a smile.

"Thank you for your cultivation, and you will definitely redouble your efforts to repay the kindness of your acquaintance." Zhao Zhenyu was grateful, knelt on the ground, and kowtowed respectfully three times.

"Get up, it's all a family, you don't need to be so polite in the future." Zhang You smiled and helped him up.

"My lord, you only said two points, and the third?" Zhao Shizhen interjected, two points are enough to make a leap forward in the development of the heat engine, and I don't know what the third point will be?

"Third?" Zhang You was stunned, just said it casually, this question really stopped him, and touched his nose: "Patronizing the excitement, forget, when I think about it, I'll tell you later, don't talk about this, let's talk about firearms, I have been away for a while, are there any new inventions?" ”

New inventions are not autumn leaves, you can grab a handful at will, the development of firearms has been very rapid, and in just a month, it is normal that there is no development.

Seeing that Zhao Shizhen and Xu Guangqi were a little embarrassed when they reported that they were not, Zhang You hurriedly encouraged them a few words, and talked to Guo Zaoqing about the planting of sweet potatoes and corn, and asked him to find a way to find some experts in planting crops.

A lot of rumbling, it was almost evening when he finished speaking, Zhang You rarely came back, invited everyone to eat at home, everyone agreed, only Zhao Zhenyu was a little embarrassed to refuse, remembering that he was also a newlywed Yan'er, Zhang You was not reluctant, and forced him to give him a silver ticket, which was regarded as making up for him.

Zhao Zhenyu is a relatively boring person, he is only interested in invention and creation in his life, and he doesn't have much feeling about powerful materials and the like, but no one is still a little happy when he sees that the face value of the silver ticket is one hundred taels, which is enough to top him for several months.

People are in good spirits on happy occasions, carrying a pair of beautiful gold earrings, he walked back to his home in the depths of the alley, and couldn't wait to knock on the door, and waited for a long time before an impatient voice came: "Knock knock, what is there to knock?" I'm not deaf, and I don't see you working so hard when I go to bed. ”

Then the door opened, revealing a slender figure, the woman was greased and powdered, and her appearance was as beautiful as a flower, it was the pretty lady that Hatch was looking for. If you leave halfway through, press CTRL+D to save the current page to your favorites so you can watch it later!
