After listening to the technician's words, Uncle Ding thought about it and realized that it was the same. Today's external environment is not the peaceful era before the disaster. If you hide in the mountains, there is no dragnet-style investigation to hide for a few months. The extreme cold and lack of oxygen are natural. The environment was enough to kill anyone.
This is like climbing Mount Everest or going to the North and South Pole before a disaster. Without sufficient preparation, professional protective equipment and enough warm clothes, only cold and death are waiting for you.
But while watching the technicians install these bioresponsive facades, Uncle Ding suddenly thought of his daughter Ding Ning, as well as Mo Qingyan and the others.
Although Uncle Ding has not visited the shelter where Ding Ning and Mo Qingyan are staying, Qin Lan knew something about that shelter when he went there before and reported it to him when he came back, so Uncle Ding knew that they did not have a greenhouse there, so he There is no oxygen generating equipment.
Out of concern for his daughter, Uncle Ding asked the technician: "Is it troublesome to use a device like this to anesthetize yourself? If a private shelter wants to build a similar device, can it be made?"
The technician glanced at Uncle Ding in surprise. He seemed to think that the SWAT captain's focus was a bit strange, but he still explained: "It wouldn't be troublesome if we just made a similar simple device. It's just about the oxygen production efficiency of the equipment." And maintenance and cleaning will be very troublesome.
For a private shelter, if you want to generate oxygen, it is recommended to build a greenhouse. As long as there is electricity and water, the greenhouse can provide both food and oxygen. It is much simpler than buying a set of such oxygen generating equipment. "
The technician's words made Uncle Ding's heart sink, and he was suddenly worried about Ding Ning and the others.
He deliberately asked the technicians if they had extra equipment, but when the words came to his lips, Uncle Ding swallowed them back.
The equipment in front of him is for the survival of more than 20,000 people in the entire shelter. Uncle Ding cannot embezzle it for his own personal gain, even if he only needs a small part.
And rather than getting a set of equipment for Ding Ning and Mo Qingyan, it would be easier for them to move to a shelter.
This will not only solve their survival problem, but also provide guarantee for their safety.
After all, in the shelter of the police station, Uncle Ding, as the captain of the special police, was more or less in charge, and Ding Ning's safety was still guaranteed.
After figuring this out, Uncle Ding stopped asking the technicians any more questions and made up his mind that no matter what mood Ding Ning was in this time, he would send someone to pick her up.
At worst, I would have to bow my head and admit my mistake to her.
There is no shame in bowing your head and apologizing to your daughter.
—————————
Official shelters have well-produced oxygen-generating equipment, but Chen Xin can only do it himself.
However, Chen Xin did not build another workbench, but borrowed the workbench that came with the weapon cabinet.
Although this is a workbench used to make and maintain weapons, it has all the necessary tools, and related auxiliary materials such as tape and glue are also quite complete. Even if the tools are not very handy, Chen Xin can modify these existing materials on hand. , it is not particularly difficult to get a simple oxygen tank.
Make a hole on the side of the plastic box, connect the pipe and the micro vacuum pump, and then connect an upright pipe to the screen window placed in the plastic box to ensure that the water flowing out of the pipe can flow to the screen window. , and then add a fill light in front of the screen window, this simple algae oxygen generating tank is completed.
Although this thing is horribly rough, the pipes are all sealed with tape and glue, and the pipes and screens lack support, making it look shaky, but according to the system's judgment, it is still a complete survival device.
"A simple algae biological oxygen production tank"
"Upgrade plan one: increase algae attachment surface, improve algae reproduction efficiency, oxygen production +10%, biomass production +5%, 100 survival points required for upgrade"
"Upgrade plan two: Change the structure of the water tank, improve the algae photosynthesis efficiency, increase the oxygen production by 15%, and upgrade the required survival points to 80"
Seeing that the system provided an upgrade plan, Chen Xin was relieved. Since this crude thing can be recognized by the system as an algae biological oxygen generation tank, the next thing he has to do is to collect materials or directly use survival points to continue upgrading this Oxygen tank.
From the two upgrade methods provided by the system, Chen Xin also judged that the two upgrade routes for this algae oxygen production tank should be upgraded one to a fuel cell route to become a biogenerator, and the other to become a pure biogenerator. oxygen machine.
And the algae corresponding to the two seem to be different. The first type is obviously more suitable for attached growth and can recycle a large amount of biomass for use in fuel cells to convert electrical energy.
The second type is phytoplankton that is obviously more suitable for planktonic life. Its purpose is only to obtain more oxygen, rather than to recycle biomass.
Regarding the two upgrade options, although he can choose both, Chen Xin obviously prefers the first option because he needs to obtain biomass fuel cells to provide power for the shelter.
After all, he still has a greenhouse that can provide oxygen. He does not need to rely on an oxygen tank to produce a large amount of oxygen. This is only an auxiliary equipment in his plan.
It's just that the upgrade of this oxygen tank cannot be carried out for the time being. On the one hand, Chen Xinxin no longer has enough materials on hand, and on the other hand, because the previous upgrades to the weapon cabinet and protective clothing have used up all the survival points in his hand.
Considering that the current oxygen content in the atmosphere is not so high that people can't breathe, and he also has a greenhouse that can provide oxygen, Chen Xin is not very urgent about upgrading the oxygen tank.
And Chen Xin, who checked the information again at this time, also realized that even if the surface and marine ecology completely collapsed and there was no sunlight for photosynthesis, the oxygen in the earth's atmosphere would be enough for humans to breathe for a long time.
Although previous global fires and meteorite impacts have consumed a large amount of oxygen in the atmosphere, the remaining oxygen is still enough for humans to use for a long time, even enough to support the dust in the sky to disperse and the earth's ecology to rebuild.
And according to Chen Xin's speculation and the data he found in the computer's files, the completely dark situation in front of him would be improved within a year at most.
Although the dust in the sky still blocks most of the sunlight, the earth's surface may transform from no light to a low-light environment within one to three years. In the ocean, which accounts for 70% of the earth's surface, algae grow in a low-light environment. Photosynthesis can already occur to produce oxygen.
In other words, humans may face hypoxia problems caused by insufficient oxygen, but they will not be unable to survive due to lack of oxygen.
The existence of oxygen concentrators only improves the living environment of humans in shelters and allows humans to live better. (End of chapter)
