Doomsday Bunker Upgrade Chapter 77: Homemade oxygen generator

After listening to the technician's words, Uncle Ding thought for a second and thought that the same is true. Today's external environment is not the peaceful era before the disaster. If you hide in the mountains, you can hide for a month without a net-type investigation. The extreme cold adds to the shortage. The natural environment of oxygen is enough to kill anyone.

This is like climbing Mount Everest or going to the North and South Poles before the disaster. Without adequate preparation, professional protective equipment and enough warm clothing, all that awaits you is cold and death.

But while watching the technicians install these biological response facades, Uncle Ding suddenly remembered his daughter Ding Ning, Mo Qingyan and the others.

Although Ding Ning and Mo Qingyan were in the shelter Uncle Ding had never visited, Qin Lan knew about the shelter when he went there and reported to him when he came back, so Uncle Ding knew that they did not have any plants there. The greenhouse does not have any oxygen production equipment.

Out of concern for his daughter, Uncle Ding asked the technician, "Isn't it troublesome to make a device like this? If a private shelter wants to build a similar device, can it be done?"

The technician glanced at Uncle Ding with some surprise, and seemed to think that the focus of the special police captain was a little strange, but he still explained: "It would not be troublesome if we just made a similar simple device, it's just the equipment. Oxygen generation efficiency and maintenance and cleaning will be very troublesome.

In the case of a private shelter, if you want to generate oxygen, it is recommended to build a greenhouse. In the case of electricity and water, the greenhouse can provide both food and oxygen. It is easier than getting a set of such oxygen-generating equipment. Lots of land. "

　　 The words of the technician made Ding's heart sink, and he was full of worry for Ding Ning and the others.

He had the heart to ask the technicians if they had extra equipment, but Uncle Ding swallowed the words when they came to his lips.

The equipment in front of me is for the survival of more than 20,000 people in the entire shelter. Uncle Ding cannot use it for his own sake, even if he only needs a small part of it.

　　 And it’s easier to get Ding Ning and Mo Qingyan to move them to a shelter than getting a set of equipment for them.

　　 This can not only solve their survival problems, but also provide protection for their safety.

After all, no matter what, in the shelter of the police station, Uncle Ding, as the SWAT captain, is still in charge of talking, so Ding Ning's safety is still guaranteed.

Having figured out this truth, Uncle Ding didn't ask the technical staff any more, and made up his mind that no matter what Ding Ning's mood was this time, he would send someone to take her over.

　　 The big deal, I lowered my head to admit her mistake.

　　 bowed his head to apologize to his daughter, not ashamed.

—————————————————————

　　The official refuge of all the oxygen production equipment produced, 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 for making and maintaining weapons, it has all the necessary tools and related auxiliary materials such as tape and glue. These materials are not particularly difficult to get out of a simple oxygen generator.

Open a hole on the side of the plastic box, connect the pipe and the micro vacuum pump, and then connect a vertical pipe, which is placed on the screen window placed in the plastic box to ensure that the water flowing out of the pipe can flow Go to the screen window and install a fill light in front of the screen window, and this simple algae oxygen generator is complete.

Although this thing is terrifyingly rough, the pipes are all sealed with tape and glue, and the pipes and screen windows lack support, and it looks crumbling, but in the system's judgment, it is still a complete survival device.

　　"simple algae biological oxygen generator"

"Upgrade plan 1: Increase algae attachment surface, improve algae reproduction efficiency, oxygen production +10%, biomass production +5%, and 100 survival points required for upgrade"

"Upgrade plan 2: Change the structure of the water tank, improve the photosynthesis efficiency of algae, increase the oxygen production by 15%, and upgrade the required survival points by 80"

Seeing that the system provided an upgrade plan, Chen Xin felt relieved. Since this simple thing can be recognized by the system as an algal biological oxygen generator, the next thing he needs to do is to collect materials or directly use survival points to Continue to upgrade this oxygen generator.

From the two upgrade methods provided by the system, Chen Xin also judged that the two upgrade routes of this algae oxygen generator should finally be upgraded: one is to take the fuel cell route to become a bio-generator, and the other is to become a bio-generator. Pure oxygen generator.

And the algae corresponding to the two also seem to be different. The first type of multicellular algae is obviously more suitable for attached growth and can recover a large amount of biomass for fuel cells to convert electricity.

　　 The second type is obviously more suitable for planktonic algae. The purpose is to obtain more oxygen, not to recycle biomass.

As for the two upgrade options, although you can choose both, Chen Xin obviously prefers the first option~IndoMTL.com~ because he needs to obtain biomass fuel cells to provide electricity for the shelter.

　　 After all, he still has a planting greenhouse that can provide oxygen, and he does not need to rely on an oxygen box to produce a large amount of oxygen. This is only auxiliary equipment in his plan.

It's just that the upgrade of this oxygen generator box cannot be carried out for a while. On the one hand, Chen novice does not have enough materials, on the other hand, because the previous upgrade of the weapon cabinet and protective clothing has already used his survival points. It's over.

Considering that the current oxygen content in the atmosphere is not so high that people can't breathe, he still has a planting greenhouse to provide oxygen, and Chen Xin is not very urgent to upgrade the oxygen generator.

And Chen Xin, who re-checked the data at this time, also realized that even if the surface and marine ecology 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 the 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, and 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 data on the computer, the situation in front of him in complete darkness will last for at most a year and it will improve.

Although the dust in the sky still blocks most of the sunlight, the earth's surface may change from no light to a low-light environment within one to three years, and in the ocean, which occupies 70% of the earth's surface, algae are Photosynthesis can already produce oxygen in low light environment.

　　 In other words, humans may face hypoxia caused by insufficient oxygen, but they will not be unable to survive due to lack of oxygen.

The existence of 　　 oxygen concentrator is only to improve the living environment of human beings in the refuge and make humans live better.
