Chapter 77: Homemade oxygen generator

After listening to the technicians, Uncle Ding thought about it and thought it

was true. Today’s external environment is not the peaceful age before the

disaster. He went to the mountains to hide. Without a dragnet-style

investigation, he could hide for a month. The extreme cold and lack of oxygen

are natural. The environment 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, only cold and death are waiting for you.

But while watching the technicians install these biological reaction facades,

Uncle Ding suddenly thought of his daughter Ding Ning, and Mo Qingyan and

others.

Although Ding Ning and Mo Qingyan have not visited the refuge where they are

located, Qin Lan knew everything about that refuge when she went there before

and reported to him when she came back, so Uncle Ding knew that they did not

plant greenhouses there. There is no oxygen generator.

Out of worries about his daughter, Ding Shu asked the technician, “Isn’t it

troublesome to numb the equipment like this? If the private shelter wants to

build a similar device, can it be done?”

The technician glanced at Uncle Ding in surprise. It seemed that the focus of

the special police captain’s attention was a bit strange, but he explained:

“If you just make a similar simple device, it’s not troublesome. It’s just the

oxygen production efficiency of the equipment. And maintenance and cleaning

will be very troublesome.

If you want to produce oxygen in a private refuge, it is recommended to build

a planting greenhouse. When electricity and water are still available, the

greenhouse can provide both food and oxygen, which is much simpler than

getting a set of oxygen production equipment. "

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

for Ding Ning and the others.

He deliberately asked the technicians if they had extra equipment, but when

this word came to his lips, he was swallowed by Uncle Ding.

The equipment in front of him is used by more than 20,000 people in the entire

refuge. Uncle Ding cannot embezzle from it for his own benefit, even if he

only needs a small part of it.

And instead of getting a set of equipment for Ding Ning and Mo Qingyan, it is

easier for them to move to a shelter.

This can not only solve their survival problems, but also provide guarantees

for their safety.

After all, in the refuge of the police station, Uncle Ding is still in charge

as the captain of the special police, and Ding Ning's safety is still

guaranteed.

After figuring out this truth, Uncle Ding did not ask the technicians any

more, and made up his mind that no matter what emotions Ding Ning made this

time, he would send someone to take her over.

The big deal, he lowered his head to admit her mistake.

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

——————————————————

The official refuge of all the oxygen production equipment produced, Chen Xin

could 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

tools, and the related auxiliary materials such as tape and glue are also

quite complete. Even if the tools are not too handy, modify Chen Xin’s

existing materials. , It is not particularly difficult to get a simple oxygen

generator box out.

Make a hole on the side of the plastic box, connect the pipe and the micro

vacuum pump, and then connect a vertical tube, and put it on the screen window

placed in the plastic box to ensure that the water flowing out of the tube can

flow to the screen window , And add a fill light in front of the screen

window, and this simple algae oxygen generator is complete.

Although this thing is terribly rough, the pipes are all sealed with adhesive

tape, and the pipes and screens are lack of support, and they are crumbling at

the sight, but in the judgment of the system, it is still a complete survival

equipment.

"A simple algae biological oxygen generator"

"Upgrading plan 1: Increase the algae attachment surface, improve the algae

reproduction efficiency, oxygen production +10%, biomass production +5%,

upgrade required survival points 100"

"Upgrade plan 2: Change the structure of the water tank, improve the

efficiency of algae photosynthesis, oxygen production +15%, upgrade required

survival points 80"

Seeing that the system provided an upgrade plan, Chen Xin was relieved. Since

this simple thing can be recognized by the system as an algae biological

oxygen generator, what he has to do next is to collect materials or directly

use survival points to continue to upgrade this Oxygen box.

From the two upgrade methods provided by the system, Chen Xin also judged that

the two upgrade routes of the algae oxygen generator should finally be

upgraded to a fuel cell route to become a biological generator, and the other

to become a pure system. Oxygen machine.

And the algae corresponding to the two seem to be different. The first type is

obviously more suitable for attachment and growth of multicellular algae,

which can recover a large amount of biomass for fuel cell conversion of

electricity.

The second type is obviously more suitable for planktonic algae. The purpose

is to obtain more oxygen, not to recycle biomass.

For the two upgrade options, although you can choose both, Chen Xin obviously

prefers the first option ~www.mtlnovel.com~ because he needs to obtain biomass

fuel cells to provide electricity to 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 box can't be carried out for a

while. On the one hand, Chen Xin doesn't have enough materials on his hands.

On the other hand, he has already used up his survival points by upgrading the

weapon cabinet and protective clothing.

Considering that the current atmospheric oxygen content is not too low for

people to breathe, he also has a planting greenhouse to provide oxygen. Chen

Xin is not very urgent to upgrade the oxygen box.

And Chen Xin, who rechecked the information at this time, also reacted. Even

if the earth's surface and marine ecology are completely collapsed, and there

is no sunlight for photosynthesis, the oxygen in the earth's atmosphere will

be enough for humans to breathe for a long time.

Although previous global fires and meteorite impacts have consumed a lot 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 and the

ecological reconstruction of the earth.

And according to Chen Xin's speculation, and the data he found in the computer

data, this completely dim and non-light situation will be improved for at most

one year.

Although the dust in the sky still blocks most of the sunlight, the surface of

the earth may change from no light to a low-light environment within one to

three years. In the ocean, which occupies 70% of the earth's surface, algae

are in the low-light environment. You can already perform photosynthesis to

produce oxygen.

In other words, humans may face hypoxia caused by insufficient oxygen, but

they will not be unable to survive due to hypoxia.

The existence of oxygen concentrator is only to improve the living environment

of human beings in the refuge and make humans live better.
