If conditions permit, Li Sheng really wants to arrange some liberal arts subjects in Chengxi Academy.
Although there are some now, they are all very hard-core liberal arts subjects such as geography and geology.
Since it is an academy, how can it be done if the subjects are not complete?
But there is no other way. What Datang lacks most now is really science and engineering talents - this is what the empire needs most when it is first established.
Therefore, Li Sheng could only send King Luo Bin to test the leather performance for himself with tears...
If I had the conditions, I wouldn't want to do this.
If the conditions are sufficient, there is no harm in setting up a music school, art school, etc., let alone liberal arts subjects.
But... isn't this unconditional?
Li Sheng himself didn't get enough rest, so naturally he had no choice but to do this first.
Of course, Li Sheng had no choice but to arrange for all teachers and students to steam leather, which made the whole college stink. He did not expect to get results quickly.
but……
This morning, Li Sheng knew that he had underestimated the power of concentrating his efforts to accomplish big things.
Early in the morning, King Luo Bin took several friends who were doing experiments together, and a project team went straight to Li Sheng's small yard.
When Li Sheng opened the door sleepily, the group of people immediately poured in.
"Principal, principal! We are done!"
"Pi, Pi!"
"The principal doesn't brag or make fun of me, my skin is really top notch this time!"
"It's done! Principal, look at it!"
Li Sheng watched in bewilderment as these guys got excited with him for a long time. He didn't react at the first moment and was completely confused.
When King Luo Bin handed over an "experiment report" written in a standard format, Li Sheng suddenly woke up. He had been busy recently, and so were these students...
This report...
Li Sheng picked it up and took a look.
soon……
His face changed.
After all, there is strength in numbers.
Come together throughout the academy and try out various varieties and types of leather.
It turned out that the high-quality seals that Li Sheng thought would take at least half a year to test were finally here.
Of course, the leather I tried this time was a less popular type of cowhide.
Because of their average physical strength and intolerance to rough feeding, they are rarely raised. However, in this experiment, a large number of various leathers were collected and some samples were obtained.
I didn't expect it to be tested...
Compared with the previous deerskin, it is really improved significantly.
The sealing performance of the deerskin tested by Li Sheng before was less than 60% of that of rubber.
This time it reached 80%!
Even though the improvement is only 20%, even this 20% is beyond the reach of the vast amount of leather.
Because the sealing performance of most leathers is actually not as good as that of previous deerskin. Now we have to go one step closer and beat it by 20%. You can imagine the difficulty.
But what I didn't expect was that it actually happened now.
Li Sheng could only say that this was a surprise, that the results were achieved so quickly...
Although the improvement is only 20% after all.
But again, 20% is still 20%.
The 20% sealing and improved energy efficiency are far more than 20%!
The energy efficiency of the original buckskin version of the steam engine could only reach one-third of Li Sheng's design specifications, which was why it could only be used as auxiliary and emergency power for large ships.
But now if this kind of seal is replaced, the situation can be said to be completely different.
Once replaced, the energy efficiency can be improved to at least two-thirds of the design index.
Then... this steam engine will naturally no longer be used as auxiliary power and emergency power, but can be used as the main power!
Of course, in order to save fuel and save lives at sea, Li Sheng estimated that if people wanted to sell ships in industrial areas, they would probably use steam power as a backup after buying them.
But this performance improvement, range improvement, and various improvements are really impressive!
Li Sheng was suddenly happy.
This leather test can basically come to an end now, Academy...
After all, it is also a place for teaching and reading, so there is no need to make the floor smell weird.
And on the other side...
With this thing in place, the next step is to go to the shipyard...
Aren't we building a group of boats now to prepare dumplings?
With new advanced seals, energy efficiency is significantly improved.
Even though the steam engine in the first large ship was completed due to artistic conception, and it was the first trial prototype, it was mainly for testing. The design at that time was based on the principle that it could be used, so there was no window for modification.
Everything that can be sealed has been sealed, and modification is basically impossible.
But the countless large ships to be produced in the next phase...
On these ships, this thing has a lot of potential!
And besides these, there are other uses.
For example, to put it simply, the first thing is the land-based steam engine that I am currently busy designing.
Of course it is not the "steam cattle" that Li Er mentioned, that is, an internal combustion engine, but it is the model used by steam trains, and it is also a crucial model.
This design...
Li Sheng originally thought that the design was not difficult, but because he was not very optimistic about the new leather material test, he couldn't help but feel nervous. This design was naturally very difficult and needed to be changed.
Now that we have this good thing, the design performance indicators no longer need to be so outrageous, and we can directly return to normal.
My workload can also be reduced a lot...
This time, Li Sheng was so happy.
Originally, King Luo Bin and the other scholars were very excited, but now Li Sheng quickly read the report and was even more excited than them.
"Ha ha ha ha ha ha ha!"
"good!"
"You guys did a great job!"
Li Sheng's eyes suddenly lit up, and he suddenly woke up from his confusion in the early morning. He burst out laughing on the spot.
When King Luo Bin and others saw how happy and excited Li Sheng was, they were stunned for a moment, and then looked at Li Sheng nervously...
After all, during this period of time, although everyone was helping Li Sheng conduct experiments, Li Sheng really didn't explain much about the final purpose of the experiments.
Although everyone didn't say it, after a lot of hard work, they couldn't help but secretly mutter to themselves, what's the point of doing this...
When Li Sheng smiled, King Luo Bin suddenly became very nervous.
Maybe it seems...this leather test is really important?
Just when King Luo Bin and others were thinking nervously, Li Sheng suddenly raised his head, looked at King Luo Bin, stretched out his hand and patted King Luo Bin's shoulder hard several times.
"Well done!"
Li Sheng's face was full of smiles, "You have done a very good job this time!"
After thinking for a while, Li Sheng felt that he must give King Luo Bin a full reward.
The reason was nothing else, but Li Sheng remembered something.
In the previous life, I remembered it clearly.
Edison, the so-called king of inventions, seems to be famous in history, but in fact... Only after truly understanding the detailed historical data, I realized that many inventions and research results were actually made by Edison's employees, and he himself was actually an inventor.
