Into Unscientific Chapter 636

 In the office.

Looking at Li Jue with an expectant look on his face, Xu Yun's expression did not change (after all, he was disfigured), and he quickly calculated in his mind.

 Speak the truth.

Although he didn't understand Li Jue's intention of coming to him today until now, Xu Yun didn't feel much obvious surprise in his heart.

after all

As early as the moment when he set his abacus on the tandem electrostatic accelerator, he had already anticipated that this day would come.

 When mentioning particle accelerators/supercomputers, energy consumption must be involved.

This kind of understanding can even be said to be a bit bad in later generations, even many liberal arts students who have little understanding of particles have this concept.

 Hence, Xu Yun has been preparing for these things from a long time ago.

Although Li Jue spoke more than a month earlier than he expected, the overall impact was not that big.

　About half a minute passed.

Feeling that the time was almost up, Xu Yun touched his chin and said to Li Jue:

“Director, to be honest, I have considered the issue of electricity before.”

“The power situation of our base is very clear now. It is a standard situation where the power supply structure is simple but the power consumption structure is complex.”

“So if you want to balance the power consumption of the base, it may not be possible to simply use a peak-shaving solution.”

 Hear this.

Li Jue nodded in agreement.

The power supply structure Xu Yun mentioned is the three major sources of power at the base, that is, the self-operated thermal power plant of the base, as well as the power transmission from Shanzhou Hydropower Plant and Qiaotou Gucheng Thermal Power Plant.

The electricity structure refers to the many projects that require electricity in the base. The total number of large and small projects can probably be listed as thirty or forty, or even more.

 Hence, if you want to solve the power problem, simply reducing expenditures will not work, you must [open source].

 Then Li Jue glanced at Xu Yun and said:

“Xiao Han, you are right, simple peak load adjustment may be able to cope with it for a day or two, but if you want to make the base fully operational, you must think of other methods.”

“But the problem is that it's easier said than done.”

After speaking, Li Jue took a long breath, put his hands behind his back, and introduced some data in detail:

“Xiao Han, the current power generation capacity of our base's self-operated crematorium is 1,500 kilowatts, the total installed capacity of Gucheng Power Plant is 1,278 kilowatts, and the turbine generator set at the hydropower station is 675 kilowatts.”

“Among them, the power supply ratio of the Gucheng Power Plant is 38%, which is more than 480 kilowatts, and the hydropower station is 28%, which is close to 200.”

“The combined power generation specifications of the three parties are about 2,200 kilowatts. With power supply for more than ten hours a day, the total power supply can reach about 26,000 kilowatt hours.”

“According to our preliminary calculations, once several projects start operating, the base's daily power consumption will increase at least ten times, which means the daily consumption will be more than 260,000 kilowatt hours.”

Xu Yun blinked and pretended to be puzzled:

“Director, in this case, can you consider transferring some units from other places, such as the capital?”

“Or ask the organization to issue instructions to increase the proportion of power supply from Qiaotou power plant and hydropower plant?”

  “It's difficult.”

Li Jue immediately shook his head after hearing this and said:

“There are currently many friendly units in Xihai Province that need electricity, and the 38% distribution ratio has already caused many comrades from other units to have objections—after all, we are only in the Xihai Mining Area on the surface.”

“If we forcibly increase the power supply ratio, it will be easy to expose the secret. Secondly, even if all the power in the ancient city is allocated to the base, the power will still not be enough for our requirements.”

“As for the crew in the capital, Xiao Han, I'm afraid you don't understand the situation. How can there be any spare crews in the country now?”

Li Jue's reaction was partly acting, but most of it was the truth.

These days, Xihai Province is considered a standard industrial province. In ancient terms, it is a place for farming and mining. There are really a lot of industrial units in the province.

 On the surface, Base 221 is just the No. 1 Machinery Factory of Xihai Province and the Xihai Mining Area. The power distribution organization must also consider the emotions of other units. If there is no brain power supply, any fool will know that there is a problem with the base.

  And deploy the units.

 At present, domestic generator sets are mainly manufactured by Harbin Steam Turbine Factory and Modu Electric Machinery Factory, and the queue is now three years away.

Even if the organization allows the 221 Base to jump in first, according to the current production efficiency, it will take at least half a year including debugging.

Not to mention that the Modu Motor Factory is currently working hard to produce a set of foreign trade orders for export to Persia. This is one of the few industrial export orders for the Rabbits today, and it is impossible to interrupt it from any angle.

 So the possibility of finding "foreign aid" is actually infinitely close to zero.

Xu Yun naturally knows this truth. The purpose of asking this question is just to facilitate the following rhythm:

“In this case, director, we can only think of a solution based on the type of power generation.”

Li Jue was startled and said subconsciously:

 “Type of power generation? What does this mean?”

Xu Yun nodded slightly towards him, raised three fingers and explained:

“Director, at present, our common types of power generation are mainly hydroelectric power generation and thermal power generation, and there is also a less common type of wind power generation.”

"wind power?"

Li Jue took Xu Yun's words and touched his chin with his thumb, thinking he had guessed what Xu Yun was thinking:

“Oh, it's the kind of windmill that huffs and puffs, right? - What, Xiao Han, do you want to build wind power?”

 Xu Yun, a clinker, waved his hand and said two words in a concise and concise manner:

 “Don't do it.”

 What a joke.

 It is true.

 Wind power is indeed one of the cleanest energy sources at present, but its price/performance ratio is not very high.

 The construction cost of a wind turbine is generally close to tens of millions in later generations, and the power generation per hour is only about 2,000KW.

If you take into account the cost of building a wind farm in the early stage and the later operation and maintenance costs,

 Even in plateau areas like the West Sea, for today's rabbits, it is an expense that requires selling blood.

 In the future, domestic wind power generation will basically rely on feed-in tariff subsidies. It is considered good to recover the cost within ten years.

This thing is more suitable for places that are short of coal. For example, it is used in Europe. If you really want to engage in wind power generation in this era, you might as well use the cost to expand the production line of generating units.

Xu Yun then remained silent for a few seconds and said:

“Director, what I mean is that in addition to these three methods of power generation, we can also use a brand new method.”

“For example, have you heard of photovoltaic power generation?”

“Guangfu Power Generation?”

Li Jue's eyes immediately showed a ray of clarity that had not been polluted by knowledge:

“Guangfu Power Generation, what is this?”

“Could it be that the Cantonese people chase after the Fujianese people and chew them to death, and then the Fujianese people run in circles like hamsters and use the running belt to generate electricity?”

Xu Yun looked at Li Jue with a look of astonishment for a few seconds:

 Brother, it's a pity that you don't write novels with your imagination.

 Then he took a deep breath, temporarily put aside the desire to complain, and said:

“Director, I'm talking about photovoltaic power generation, the light of light, the volts of voltage.”

“In short, this is a way to convert light energy into electrical energy for transmission and use, which is the solar energy above our heads.”

 In 2023, when Xu Yun traveled through time.

If the electric power field is regarded as a family, then thermal power and hydropower are undoubtedly the well-deserved big brother and big sister.

 Nuclear power is the second elder brother, and wind power is the youngest.

 There is a younger brother between the second brother and the younger sister, and that is Optoelectronics.

 From a desert solar array, to a children's toy, as simple as a residential roof, to as high-end as a spacecraft, this little guy can play with it.

 The principle of photovoltaic power generation is attributed to the atomic energy band structure, involving the concepts of valence band and conduction band.

 The so-called valence band refers to the region relatively close to the nucleus.

 The electrons here are tightly sucked and cannot escape easily.

 The conduction band is a region far away from the nucleus, where electrons are unregulated and relatively free.

If there is an external electric field that causes these electrons to run, the material will conduct electricity.

 In addition to these two areas, there is another area above the valence band and below the conduction band.

 This region does not allow electrons to exist, which is the forbidden band.

 So in the self-heating world, there are generally two completely different materials:

 A forbidden band is very narrow, or there is no forbidden band at all.

 At room temperature, its outer electrons in the valence band can easily jump to the conduction band.

 This is a conductor.

On the contrary, if the bandgap of the material is very wide, generally greater than three electron volts, and the electrons stay in the valence band at room temperature, then it cannot conduct electricity.

 This is an insulator.

 Materials with an energy gap less than 3 eV between the valence band and the conduction band are semiconductors.

These electrons will form something called a PN junction, with the two ends showing different electrical properties, thereby forming an electric field pointing from N to P. This electric field is formed spontaneously, so it is also called the self-constructed electric field of the conductor.

 As for the role of the photovoltaic effect, it is to "tempt" those already paired valence band electrons again.

 That is, the electrons in the valence band absorb the energy of light, become higher in energy, and jump to the conduction band.

The hole that has detached the electron will be thrown to both sides under the influence of the self-built electric field, forming an electric field pointing from P to N.

 This is the photo-generated electric field, the direction is opposite to the self-constructed electric field.

 At this time, as long as an external circuit is connected, current will be generated in the circuit due to the existence of potential difference.

 Very simple and easy to understand.

Of course.

Photovoltaic power generation and solar power generation are strictly two concepts, and the relationship between them is somewhat similar to subsets and sets:

Solar photovoltaic power generation includes many types such as photovoltaic power generation, photochemical power generation, light induction power generation and photobiological power generation. To be honest, even the names have to be distinguished.

 But that is the situation in 2023.

At this time, due to the relatively backward productivity, Xu Yun will definitely not be able to come up with standard photovoltaic technology, and some magical modifications will inevitably be made.

 Just like many people think that 3080 is more expensive than 4070ti, it is a performance optimization.

Hence, whether it is photovoltaic power generation or solar power generation, there is no need to be too serious in the dungeon.

 “Use solar energy to generate electricity”

Li Jue raised his head and glanced at the window of the office. At this time, a ray of sunlight happened to shine directly on a potted plant near the window edge.

 Light has energy.

To be honest, Li Jue naturally understands this truth—and he didn't understand it after entering the base. He already knew it when he was studying.

But the idea of ​​converting this energy into electricity had never occurred to him or heard of.

He actually remembered what Lao Guo once said about hydropower and nuclear power plants. The energy of that thing was also very high, but it was obviously not the same thing as solar energy.

 In fact, what Li Jue didn't know was.

 It was actually very late for modern society to formally apply the photovoltaic phenomenon to real technology. It was only last year that the most primitive photovoltaic cells were connected to the grid for the first time.

 It will take another two years for Neon to achieve a breakthrough of 242W photovoltaic cells.

 As for this technology, it was not until the late 1980s that this technology truly began to be regarded as “living energy”.

Then Li Jue thought of something again, took his eyes away from the window sill, and looked at Xu Yun again:

“Xiao Han, is the photovoltaic technology you mentioned complicated to implement?”

Xu Yun shook his head and explained:

“Director, if you are referring to the complete version of photovoltaic power generation, it will definitely take time and effort to produce.”

“But if you just make a beggar's version of the power supply module that can support the base, it's not that difficult.”

“I remember that the magic city in China already has a relatively mature colloidal lead-acid battery technology, and then it is enough to burn the cuprous oxide and then use a diffusion furnace to dope it.”

There are many key links in solar power generation, but the core one is undoubtedly the production of solar panels.

As a DIYer, Xu Yun is very familiar with this.

 First of all, you need to prepare a piece of copper, use sandpaper to remove all sulfide or surface corrosion, and then place it on the electric stove for burning.

As the copper sheet is heated, oxide layers of many colors will appear on the copper sheet, which will eventually be replaced by a layer of black copper oxide.

Then the copper sheet is cooled. Due to the shrinkage rate, the copper oxide will automatically fall off, and the remainder is cuprous oxide.

Then find the silicon wafer substrate (DIY circles generally use glass), make a pn junction on the silicon wafer, find a PECVD set to 1/4 wavelength to coat the reflective film, and then use a screen brushing machine to brush the slurry. That's it.

 Later generations usually use DuPont or Samsung paste for painting paste, but for Li Jue or the base, they only need to make their own aluminum paste.

 According to Xu Yun's calculation.

 A 100,000-kilowatt solar panel requires about 10 tons of aluminum paste, which is not a particularly big burden for rabbits.

If everything goes well.

The base can produce these finished solar panels in about one and a half months, and the inverter is not something he needs to consider.

  After all, these days, the Rabbits have a lot of big-name academic committee members. If they can't come up with a matching inverter, they can just write a resignation report.

At the same time, the colloidal lead-acid batteries produced in Shanghai can be used to store electricity. Xu Yun doesn't know much about the quality of colloidal lead-acid batteries these days, but if he remembers correctly, this thing should be an early item. Already established technology.

  A set of colloidal lead-acid batteries in later generations can probably withstand deep charging and deep discharging about 500 times. Now, even if calculated at 50% of the times, it can last more than 200 days.

Of course.

 The specific plan still needs Xu Yun to go back and summarize it in written form. At the moment, he and Li Jue mainly have a preliminary conversation about their intentions - after all, Li Jue is a complete novice in technology.

However, although Li Jue does not understand the in-depth theory, he understands donkeys.

So after Xu Yun introduced the related concepts of photovoltaic power generation, Li Jue's eyes were filled with little stars:

“Xiao Han, let's go back and work hard to compile this photovoltaic power generation technology into a document as soon as possible.”

“No, give it within three days. Submit the documents within three days. Is there any problem?”

Xu Yun has no objection to this:

“No problem, I'll start preparing when I get back.”

Li Jue nodded with satisfaction.

Xu Yun then raised his eyes to look at Li Jue and asked tentatively:

“Director, if there's nothing else, I'll leave first?”

"etc!"

As a result, just when Xu Yun was about to leave, Li Jue suddenly stopped him:

 “Xiao Han, there is one more thing.”

 Xu Yun was suddenly startled:

 “Is there anything else?”

Looking at Xu Yun, who was a little confused, Li Jue's expression suddenly became a little subtle:

“Xiao Han, actually this is the main purpose of coming to you today. There is a writer from the capital who wants to meet you.”

 “A writer from the capital?”

The expression on Xu Yun's face became more and more confused:

 “Who?”

 Writer?

 These days, domestic writers say more or less. If you add the condition of being eligible to come to the 221 Base, the options become even narrower.

 Could it be Jian Bozan?

Or Lao She?

 Or is it Chi Zijian?

However, Li Jue opposite him had no idea of ​​revealing the secret. Instead, he pointed to the next door:

“That writer is next door. You'll know when you go and see him.”

Xu Yun thought about it, and he was just a writer, so there was nothing to care about.

I guess the people in the capital wanted to leave some mission biographies for me, so they sent a reporter-like writer over to chat with me and conduct an interview?

 Subsequently, under Li Jue's personal guidance, Xu Yun's wheelchair arrived in front of a room next to the office.

 Then Li Jue stopped:

“Okay, Xiao Han, I won't go in. You can go see that comrade by yourself.”

Xu Yun nodded:

"OK."

 After Li Jue leaves.

Xu Yun stepped forward and knocked on the door, and found that the door was ajar.

So he pushed the door open and pushed the left and right wheels of the wheelchair with both hands to enter the house.

This room is the reception room where Li Jue usually receives guests. In addition to the wooden table, there is also a set of simple sofas and a small recliner.

 At this moment, I saw a person half-lying on the recliner, looking like he was resting.

After hearing the movement at the door, this person also opened his eyes, sat up from the recliner, and showed a warm smile to Xu Yun:

“Comrade Han Li, we finally meet.”

The moment he saw the other person's face, Xu Yun's breathing, no, it should be said that every cell in his body stagnated for an instant!

 Three hours later.

Xu Yun left the room in a daze, looking as if he had been spoiled.

 But in Xu Yun's eyes, it was clearly visible.

 A blazing flame is burning.
