"Well, let him rest. But this job is also quite a workout. If the generator you designed is like this, I suggest you crank it whenever you have time. That way, at least you can get a strong body."
Lin Hai knew that his words were a bit harsh. After all, all the researchers in the laboratory had dark circles under their eyes, and it looked like they had not had a good rest on weekdays. As the principal, leader, and the originator of the concept of "electricity", Lin Hai could not be too harsh on them.
"But you have worked hard too. Take a few days off after today. Research is not something that can be accomplished overnight." Lin Hai suddenly remembered the "staying up late to exercise can make a strong body" meme he had seen before, and felt that they were actually similar.
Considering the difficulty of training researchers in this world, Lin Hai still feels that it is better to take it slow and steady.
"I know you feel a little aggrieved. After all, you have nothing but the few words I gave you. It's not easy to get to where you are today. Overall, your efforts and achievements are worthy of recognition."
Lin Hai, well-versed in the essence of the "sandwich feedback method," continued, "But you should also be aware that it's unrealistic to put such a machine to practical use, so you need to explain your subsequent plans. Overall, I can give the Power Plant an 80 for its work during this time, provided you understand where the 20 points are deducted."
"Principal." He Chun took a deep breath and quickly calmed himself down.
From this point, Lin Hai could see He Chun's growth. If it were in the past, Lin Hai would just say a few words like this and He Chun would cry for half an hour.
Sure enough, work makes people grow.
Lin Hai feels that we also need to seriously consider those who grow slowly. Is it because their workload is not saturated enough, or is the pressure not great enough?
Hmm, I was thinking wrong.
Lin Hai quickly signaled He Chun to continue.
"You mentioned the concept of 'magnetic electricity' at the time. Our understanding of 'magnetism' is magnets, which now seems to be correct. From the information provided by the iron ore, we can see that the iron ore in Qinghe is accompanied by magnets, so our initial work is to screen magnets.
We have no way to measure and evaluate the magnetic strength of natural magnets. In the end, we just classify them according to the weight of the pig iron blocks they can absorb. This measurement method is quite simple, but it is the first method we can think of at present.
The second is the wire.
We tested iron and copper wires of varying purity and thickness before ultimately settling on copper. However, smelting pure copper presented its own challenges. For such a solution to be practical on a large scale, the copper produced from melting copper coins alone would be insufficient.
Finally, there's the filament. Regarding the tungsten filament you mentioned... Honestly, we and the steel mill tried many methods, ultimately using acid leaching to obtain tungsten with a lot of impurities. However, we still couldn't melt this tungsten. The steel mill technicians thought it was probably a problem of insufficient temperature, but our blast furnace couldn't reach that temperature...
So in the end, we still chose what you called the 'worst option', which is carbonized bamboo filaments, but such bamboo filaments are quite fragile...so we haven't made many so far, and the whole device is not easy to move after it is installed..."
As the lecture continued, He Chun's voice became smaller and smaller, until it was almost to the point where only Lin Hai, who had scored the highest, and she could hear it clearly. She had completely lost the energy and spirit she had at the beginning.
That's right. No matter who has gone through so much hardship and made a device that only worked successfully for more than ten minutes, when facing the dark face of his leader, he would feel a little insecure.
"You basically reproduced what I told you, which is great," said Lin Hai.
"But I want to tell you that I don't know much. Don't ask me why I know, I just know. But what I know is limited. However, the problem you are facing now does not require new technology to solve. The answer actually lies in our past production and research. Now we can discuss it together."
Lin Hai took a white coat from Shi Zhen'er and put it on himself, saying, "Now, I am also a researcher. Let's take a look at what problems we have first."
