After Dr. Roman left, Yu Yifeng immediately sent the report on the table to the two research institutes of "Wild Wolf" and "Tesla".

What do scientists do? That's when it comes in handy! Otherwise, what is the point of the research institute, it is impossible to let Yu Yifeng figure it out by himself.

After receiving the news, Ding Yidong and Felix, the two general leaders, immediately realized the seriousness of the problem and held their respective discussion meetings.

This time the subject can be said to be the first confrontation between the Wolf Design Bureau and the Tesla Research Institute. Although the big scientists can't deny what PK and the like, they think that scientific research is a lot of accidents, how can it be PK?

But some young scientists are young and vigorous, and they still have a great sense of competitiveness, and of course they have some ideas in their hearts.

Of course, the people are also very excited, and in this era of poor entertainment, it is good to guess randomly, and it can be regarded as a kind of gossip news.

"Tesla or Wolf, which one do you support?"

"I'll go whichever is great!"

"Come on, you're going? Can people take a fancy to you? ”

"I'm also a master's degree from a famous brand...... "The man said halfway, and he realized the problem, graduated from a famous brand? There's as much garbage as the Noah.

This may be a daily conversation, and some people have petitioned the government to open universities and libraries to facilitate their studies.

This is of course a good thing, and Yu Yifeng has already begun to deal with these issues. Public facilities such as schools and libraries must be built, but it is only a matter of time.

As for the problem of "the temperature inside the spaceship", whether it can be solved or not, no one cares, and the new human civilization can still be stumped by such a small problem?

First of all, let's talk about Tesla Research Institute, when the meeting order was issued, it only took ten minutes for everyone to gather. In fact, there are not many people, only twenty or thirty, but they are all the elite of the elite, the genius of the genius.

The institute has just been established, and the people's discipline and motivation are still very strong. Most of them are young lads, and a small number of them, like Felix, are big scientists, with both qualifications and skills.

Felix nodded, he was still very satisfied with the overall level of the institute, the only deficiency was that the laboratory equipment was not complete.

"Good morning, everyone, I just received an urgent research assignment."

"If you look at this report, it points out that with the development of industry, a lot of heat is generated inside the spacecraft, and this heat energy accumulates in the spacecraft, causing the temperature inside to rise.

Everyone understands it, the temperature is a bit up these days, and here's the problem. Now, the government has asked us to find a way to dissipate the excess heat into space. ”

Felix spoke eloquently, and he played the report in the form of a PPT to the scientists present, which was convenient and direct.

Some people frowned slightly, heat dissipation is not a particularly big problem...... The difficulty is to dissipate heat on a large scale in a vacuum.

Thermal energy, compared with mechanical energy, chemical energy, electrical energy, etc., is a kind of energy that is not easy to use, because according to the principle of lowest energy, under normal circumstances, it is an energy with relatively high entropy, which is not easy to convert.

Heating an area is simple, as long as there is energy, but cooling an area is relatively much more complicated. The heat in the air is too difficult to use and convert into other energy, so it can only be transferred (unless the heat is high).

What the? Air conditioning? It is impossible to dissipate heat with air conditioning inside the spaceship, which only extracts the heat from the room and dissipates it outside, but does not reduce the heat. What's the point of pumping heat from the room into the hallway? Because of the work done by the air conditioner, the heat has increased.

If you really want to use air conditioning to cool down, you have to vent hot air into the universe. As a result, people will lose valuable air. If someone really proposes this kind of plan, it is guaranteed that they will be scolded to death by Yu Yifeng. Air is a precious commodity, and people don't have enough of it themselves, and they want to emit it?

The scientists here understood the problem, and they began to discuss, discuss, and come up with a lot of theories and data.

These scientists were rigorous and unpretentious, and they began to devise various schemes. Although they are generally young, most of them are geniuses, and they have done a lot of projects.

Experiments and theories show that the radiative heat transfer of a single object is proportional to the fourth power of its surface thermodynamic temperature in the environment. To put it simply, the higher the temperature of the surface of the object, the stronger the heat exchange, that is, the hotter the thing, the faster it cools.

Another point is that the smoother and whiter the surface of the substance, the better the reflective ability, then the ability of this substance to radiate is weaker; On the contrary, the rougher and darker the surface of the substance, the stronger the ability of the substance to radiate and absorb external radiation.

One of the scientists said: "The universe can be seen as an absolute black body, that is, the radiation emitted by the spacecraft to the universe is never reflected back. Because the temperature inside the spacecraft is much higher than the outside, thermal equilibrium can be achieved by connecting the heat pipes inside and outside the spacecraft to transfer the heat from the high temperature side to the low temperature side and radiate outward. This is the existing scheme of our spacecraft.

I think the best way to do this is to increase our ability to radiate to the outside world. ”

At this time, someone stood up again: "I thought of a new graphene material with a dark color, a rough surface, and a strong ability to radiate heat. ”

"I think it is also possible to update the heat dissipation ducts inside the spacecraft, and also to increase the number of external radiant rods......"

"A liquid nitrogen heat dissipation rod was used in Tibet, which is worth learning from......"

The scientists were talking about it and trying to come up with a quick and convenient solution. Felix nodded secretly, the quality of this group of young people is still very high.

Although they didn't say it, in their hearts, they didn't want to be compared to the Wolf Design Bureau......

This is the situation of the Tesla Research Institute, and let's talk about the "Wolf Design Bureau" that people are very concerned about.

Unlike the serious discussion at Tesla Research, the Wolf Design Bureau is completely in a mess.

The researchers discussed loudly, their faces were red, and they were not convinced by each other, and the whole research institute was filled with a kind of enthusiasm and passion, and even a little fanaticism.

If Tesla is taking the road of ingenuity and meticulousness, then the Wolf Design Bureau is taking the road of ruggedness and heroism. In the eyes of the wolf, as long as it is concise and easy to use, it doesn't matter what it looks like.

This is also the original intention of Professor Ding Yidong to name "Wild Wolf".

The enthusiasm of these Russians, Ukrainians, and Chinese has been fully aroused, and they are all young people, full of pride and ambition, and they advocate steel and warships. They joined the Wild Wolf Design Bureau and were eager to engage in big projects and construction.

Looking at the drawings in his hand, Professor Ding Yidong's face sank, and he didn't know what to say. In all fairness, the content in it is logical and feasible, even very level, but ...... It's all exaggerated.

What kind of thermal difference can refrigeration scheme, large radiant sail scheme, really, any scheme has to use thousands of tons of material reserves...... Some people even suggested that it was enough to overhaul the entire spaceship.

"Everyone! Be quiet! Ding Yidong didn't scold them, these young men have heart and blood, which is a good thing, but they can't be impetuous. One is impetuous, one is exaggerated, isn't it the same as the Great Leap Forward?

"First of all, please take a look at this plan." Ding Yidong clicked the mouse and broadcast a picture on the screen.

People raised their heads in unison, and this plan was the one with the highest demand and the most positive response.

In Ding Yidong's view, although the theoretical effect is very good, the technical content is relatively high. But the disadvantage is that the amount of work is very large and time-consuming.

In the eyes of the wolves, such a big scheme has a strong metallic beauty, but ......

"I think this plan is not bad." Ding Yidong paused, "However, I want to tell you that this plan will consume more than 80% of our research institute's resource indicators and industrial indicators!"

If everyone agrees, then follow this plan! However, in the second half of the year, we probably won't be able to do anything else. ”

As soon as these words came out, they grabbed everyone's pain points, and people reacted, their resources and energy can't all be wasted on this cooling system, otherwise they will all be used up, what should we do in the second half of the year?

At this time, many people began to oppose this plan.

Even the designers of the scheme regretted that the stalls were too big and exaggerated.

Many people have woken up to the fact that the plan is not just exaggerated, but also energy-saving and effective.

So, what is the best solution to be energy efficient and effective?

While most people were thinking about issues like thermal radiation, suddenly, a young man shouted.

"Why don't we use ice?!"

"Don't we have 100 million tons of ice?"
