Obviously, Li Wensheng originally planned to use wind turbines to provide power so that his shelter would have enough power to use. However, it is obvious that the harsh environment has greatly shortened the service life of the three wind turbines.
It cannot be said that it is completely damaged now, but the paralyzed wind turbine is obviously not something Li Wensheng can repair by himself.
So he relied on a generator that was originally a backup power source to power his shelter and keep his aquaponics system running.
This obviously exceeded the consumption limit that Li Wensheng could sustain, putting him in a dilemma of energy shortage.
"Then you won't be able to hold on for much longer?" Chen Xin couldn't help but worry about Li Wensheng's current situation, especially since he just got an oxygen concentrator from Chen Xin. Although this thing doesn't consume that much power, it needs to be turned on all the time. of.
"Who says it's not the case? I've used more than half of the diesel I've stored. If I don't replenish it, I won't be able to survive for at least three months." Li Wensheng couldn't help but shook his head, with an expression on his face full of sadness and helplessness: " I have now shut down half of the aquaponics system, and the harvested vegetables and fish have been temporarily processed and stored to reduce consumption. I hope it can last a few more months or that the wind turbine can be repaired.
If I really can't survive, I will have no choice but to move my wife and children to an official shelter. I can't watch them starve to death! "
When Chen Xin heard what Li Wensheng said, he felt a little uncomfortable. He almost said that he could help Li Wensheng repair the wind turbine, but he held back in the end.
There are things you can help with, and there are things it's better not to be so overzealous about.
After thinking about it for a moment, Chen Xin, who resisted helping, still couldn't bear to die without saving anything, so he said to Li Wensheng: "Old farmer, if you have surplus output, try exchanging supplies with the official shelter. I am using planting now." The vegetables produced in the greenhouse are exchanged for supplies from the official shelter, and we can barely survive.”
Hearing what Chen Xin said, Li Wensheng's face suddenly showed a light of hope, and he hurriedly asked Chen Xin: "Then writer, how did you change it? Can you help me change some resources? I don't need anything else, just have diesel!" "
However, Li Wensheng hadn't finished speaking yet. Looking at Chen Xin's eyes staring at him, he knew that he had said the wrong thing.
Chen Xin didn't say much to Li Wensheng, but just reminded him: "There should be a shortage of vegetables and fresh meat in the official shelter. Although they raise rats and grow mushrooms, the city government also has an underground planting area near the power plant. But fresh vegetables and meat are still relatively scarce, and you, old farmer, should be able to get the gasoline you need.”
"Okay, thank you, writer! I'm going back first!" Li Wensheng was somewhat embarrassed by what he just said, so he left Chen Xin's shelter carrying the oxygen concentrator Chen Xin gave him.
Chen Xin also closed the door of the shelter and walked inside the shelter carrying a box of fresh fish.
In fact, it is not impossible for Chen Xin to help Li Wensheng change the diesel, but his relationship with Li Wensheng is not as close as that of Mo Qingyan, Ding Ning and Qin Lan. There is no problem in giving him directions, but Chen Xin has to step forward to help him change it. Gasoline, Chen Xin feels that one should not be too enthusiastic.
There have been too many stories like this in history. Although Chen Xin will not be stingy in helping others, it does not mean that he will help others selflessly.
In the end, Chen Xin exchanged supplies with the SWAT team because the fresh vegetables he had were needed by the SWAT team, but the main reason for reaching an equal deal was his relationship with Ding Ning and Qin Lan, which Uncle Ding could see. Ding Ning and Qin Lan only offered such a relatively generous exchange in terms of face.
If Li Wensheng really couldn't survive, it might be okay for Chen Xin to help him change diesel once or twice in an emergency, but it was impossible for Chen Xin to help him change diesel for a long time to maintain the operation of his shelter.
This kind of thing can only happen once and not again and again. After all, Chen Xin has no reason to waste his favors to help others.
However, the aquaponics system mentioned by Li Wensheng gave Chen Xin great inspiration and enthusiasm. He might also be able to build a similar three-dimensional agricultural system.
Give it a try next time you upgrade your shelter
This thought passed through Chen Xin's mind and he couldn't help but start to think about it seriously.
While putting the fresh fish exchanged in the freezer to freeze, Chen Xin thought about the feasibility of this idea.
The aquaponics system is a cyclic compound farming system that combines fish farming and hydroponic planting technologies. Its main principle is to use bacteria to decompose ammonia nitrogen in fish manure into nitrite, which is then decomposed by nitrifying bacteria. into nitrate, which can be directly absorbed and utilized by plants as nutrients.
The water absorbed by the plants is relatively clean and can be reused for fish, thus enabling fish farming without changing the water and growing vegetables without fertilizing.
In this way, fish, vegetables, and bacteria can form a complete cycle. Before the disaster of sunlight, the entire system can even achieve a closed-circuit cycle by feeding the fish with endless vegetables, which only takes 2- With 3 cubic meters of water and 20-30 square meters of vegetable cultivation area, it can basically meet the vegetable and fish consumption needs of a family of 3-5 people.
In the current apocalyptic environment, if we want to maintain the operation of such a system, we need supplementary lights to replace sunlight, and we must expand the planting area to provide staple food output.
Chen Xin's current planting greenhouse does not have the conditions for this. Although he had considered aquaponics when building the shelter, the energy consumption of this set of equipment was far greater than that of soil cultivation. Considering the energy consumption issue , Chen Xin gave up the idea and just built an ordinary greenhouse.
But now that the system exists, Chen Xin feels that he can still consider upgrading his greenhouse to an aquaponics system.
However, the issue of energy consumption is indeed an issue that must be considered. After all, Chen Xin can only barely maintain the operation of the shelter. The power supply relies on him getting gasoline from the SWAT team every month to maintain the operation of the generator.
Before upgrading the power system, he had no plans to increase the power burden of the shelter.
So in addition to building out the medical room, Chen Xin's first upgrade goal is the power system.
Although it was determined from the beginning that the power system was the top priority for upgrading, as the upgrade progressed step by step, other things were upgraded, but the power system remained unchanged.
Although the current power system is still sufficient, Chen Xin decided that it would be better to upgrade it, at least to install a biogas fuel cell to reduce the load on the generator.
Of course, these things cannot be rushed, right now...
Chen Xin looked at the fresh fish that had been put in the freezer and couldn't help but swallowed. He hadn't eaten fish in a long time. (End of chapter)
