Chapter 194 Engine (Leader Update 810)
An Ruosu continued: "But those few people are not very capable. The food produced every day is limited and must be distributed well. Black water is the worst food, sterilized Secondly, the best is of course cooked food.
"However, only members of the top three tiers can eat only cooked food every day; those in the middle tiers can eat one day a week and replace it with sterilized food at other times; and those on the lower tiers can eat only cooked food every day. On several floors, I almost had to rely on black water to satisfy my hunger, and occasionally ate some sterilized food. "
Everyone seemed to be listening to a story, listening to An Ruosu talking about Qingbei.
Relying on black water that is like traditional Chinese medicine to satisfy hunger every day is even more uncomfortable than having Yu Yuan provide nutrients.
The little fat guy can't stay with everyone yet. , otherwise this guy will probably be proud for a while with his hands on his hips.
Chen Mu thought carefully for a while and roughly grasped some information.
In an environment like the end of the world, it is actually not easy for Qingbei to achieve this step. Their biggest advantage is that they have a large number of people, so they can divide various divisions of labor very finely.
For example,
there are three methods of cooked rice.
On Qiming's side, the combination of awakening abilities is pretty good, which is why we have this situation now. ,
actually think about it, no matter Dong Junwei or Chen Mu, or Tang Jing and Wei Dalei, without any one of them, it would be impossible for everyone to live like this. I have to say that luck plays a big factor. After dinner.
Dong
Junwei
put An Ruosu and the others took them to the side of the room, pointed to a nameplate on the wall, and said, "
Of course we welcome you to join us, but although Qiming is not as big or as strict as Qingbei, some rules still have to be followed. As you said, this is our charter. As for other staffing and positions, I believe Zhao Xiaoyan has just told you about it. "
"Uh-huh. "The two nodded heavily.
"In that case.
Dong Junwei said: "As the chief decision-making officer of Qiming, I officially approve you to join the organization. I hope that you will love each other, work together in the same boat, and do your best for Qiming and the rejuvenation of all mankind. " "
An Ruosu and Yang Li nodded excitedly, as if they had found some long-awaited feeling again.
...
He Ying walked to Chen Mu and said, "Is it really okay to let them join so soon? ? "
They are different from the four of them, Lu Shanshan. They have come all the way to join us. If they are too coy, it will hurt people's enthusiasm." "Chen Mu paused and said; "Besides, Tang Jing said that she can guarantee that there will be no problems. From the look of her, it seems that she is eager to use these two people.
"What bad idea does she have? " He Ying asked with a smile.
"It's not a bad idea, right?" "Chen Mu chuckled.
"In order to stimulate Cao Zishan's potential, who put him in a room full of Xue Xu's farts and forced him to demolish the house with his bare hands? He Ying rolled her eyes at him.
Chen Mu touched his forehead and smiled dryly: "But it does have an effect, doesn't it?" "
Tang Jing does often do unexpected things, and sometimes the methods are very radical and embarrassing.
But the problem is that the final results of all those methods are excellent.
For example, Cao Zishan, even though he was almost smoked that time He was dead, but it was that time that he was finally able to break through his limit to less than 2 meters.
This also allowed the high-altitude fort to exert its maximum power.
He Ying sighed: "I hope these two people are sincere in seeking refuge. , otherwise, they probably wouldn't survive for a few days under Tang Jing. "
...
Chen Mu's guess was confirmed the next day.
Tang Jing seemed to have made arrangements for An Ruosu as soon as she knew her abilities.
"Next, please allow me to show you a The latest type of power machinery will also be the equipment that Qiming relies on most in the short to medium term. "
At the meeting the next day, Tang Jing showed what she had drawn all night in front of everyone.
It looked like a machine.
Roulette, tubes, linkages, pistons...
Although Chen Mu knew some of the parts , but it was a bit unfamiliar when put together.
After studying it for a while, he said with some uncertainty: "Could this be... an engine? "
Half right. " Tang Jing smiled and said, "To be precise, it's called a Stirling engine." "
The word "engine" shocked everyone present so much that their jaws dropped.
Not long ago, everyone was amazed by the clockwork device.
Many things, the principles are very simple, but they really need to be put into practice. , but that’s not the case at all.
For example, using a clockwork to drive an elevator, the principle is very simple, even Wei Dalei can explain it clearly.
However, when actually building the actual object, there are still a lot of problems, and often one part is extremely small The difference in size can paralyze the entire equipment.
Chen Mu knew it very well.
Although all the parts of the lift were made by himself, without Tang Jing, it would have been impossible for him to get the machine running for another year. Apart from anything else, he still hasn't fully understood that the cable is a speedometer.
And now.
Engine?
Is this a step too far?
Dong Junwei, Chen Mu and others at least know about Stirling engines. , the commercial textbooks are less theoretical and focus more on practicality and divergent thinking. In the chapter of physics and thermodynamics, the similarities and differences of several engines are also compared, including the advantages and disadvantages of internal combustion engines and external combustion engines.
But no one would believe that after studying a little bit of textbooks, one can build an engine by oneself. The
Stirling engine is a typical external combustion engine, and in terms of structure, it is still relatively simple.
But obviously, Neither Chen Mu nor Dong Junwei can imagine how to build a Stirling engine by themselves.
"Are our current capabilities enough? "
Although he knew that Tang Jing must be confident when he said something like this, Chen Mu couldn't help but want to confirm it.
"With our previous capabilities, it is not difficult to build an engine, but because of the material problem , there are two aspects that cannot be satisfied for the time being.
"Which two aspects? " "
The first one is the working fluid. The Stirling engine uses the expansion and contraction of gas to complete the conversion of kinetic energy. The ideal working fluid gases should be hydrogen and helium. Obviously we cannot satisfy them, but at today's scale Next, directly replacing it with air can barely meet the practical requirements;
"But the second one is not possible, because the working medium is gas, and there are high sealing requirements between the piston and the cylinder, but at the same time, the operation of the piston requires lubrication , this is a contradiction."
"Do we have lubricating oil?" Chen Mu asked.
"That's one of the reasons Stirling engines didn't become popular in the early days - we couldn't use lubricants."
