Doomsday Bunker Upgrade Chapter 71: If there is a problem, call the police first

Although Chen Xin's question was confusing, Mo Qingyan answered his question: "Plants? Photosynthesis? I have a green plant box in my bedroom. Why do you suddenly have the ingredients? Ask this?"

"The sky is obscured by dust clouds and sunlight is lost. What do plants rely on for photosynthesis? Without photosynthesis, where does the oxygen in the atmosphere come from?" Chen Xin's voice was flat, just telling a fact, but Mo Qingyan felt a panic: "Although 70% of the oxygen in the atmosphere comes from the marine ecosystem, even algae need sunlight to produce oxygen, and there is no sunlight now."

　　 "Do you mean that there is no oxygen in the atmosphere?" Mo Qingyan asked Chen Xin with a little panic.

　　 Although Mo Qingyan couldn’t see it, Chen Xin nodded: “If the conversion of carbon dioxide by photosynthesis in the ecosystem is lost, the concentration of carbon dioxide in the atmosphere will soon rise, while the oxygen content will continue. Reduce. In addition, when the unused oxygen disappears, and the oxygen content in the atmosphere is below 10%, humans should be suffocated to death."

　　 "Ah! What should we do then?" Mo Qingyan hurriedly asked Chen Xin for help, her tone inevitably full of panic.

　　In the face of such planetary disasters or environmental catastrophes, there is no possibility that personal power can change anything. After all, this book is just a slightly sloppy science fiction novel, not a strange power, even the basics A fantasy novel that doesn't teach the laws of physics.

　　 "Planting grass is a solution to the problem." Chen Xin said half a joke, half serious, and then explained: "Since you have a green planting box, this problem is actually not difficult to solve. An adult The oxygen required for normal respiration requires about 10,000 leaves of average size for photosynthesis. If a tomato with 250 leaves is calculated, you need about 40 tomatoes, covering an area of ​​about 50 square meters.”

　　Speaking of this, Chen Xin smiled. It was the first time he saw Mo Qingyan panicked. After smiling, he continued: "So as long as you build a large enough planting greenhouse in your basement , It is enough to ensure the oxygen you need in daily life, and it can also provide you with enough vegetables and food."

　　 "Ah! That's the way it turns out! So it's no wonder that when Aning and I went to your place last time, you didn't feel boring at all! It turned out not to be well ventilated, but there are plants in your place that produce oxygen!" Mo Qingyan Hearing what Chen Xin said, he finally reacted.

　　 At the same time, Mo Qingyan also realized that she felt that the air in the bedroom was good during this period not because of the good ventilation in the bedroom, but because of the green plant box in the bedroom where she had been turning on the fill light.

　　 It’s just this situation that gave Mo Qingyan a new worry. She asked Chen Xin: “Axin, what about the shelter? There are tens of thousands of people living in the government shelter. If they lack oxygen, how can they? Don’t you want to die?"

　　 "You can think of this problem, do you think the country can't think of it? The government should have a plan to deal with it." Chen Xin is not worried about this, he does not think the country will ignore this problem like himself.

If there are so many experts and scholars in the country who can't come up with a disaster response plan that can at least deal with most problems when the disaster is warned three months in advance, then this group of people is definitely a vegetarian meal.

　　 Hearing Chen Xin say this, Mo Qingyan also found that she was unreasonably worried. If there is no way for this catastrophic country that involves everyone, she can't do much alone.

However, Mo Qingyan still asked Chen Xin: "The government's refuge is all over the country, so what about our private refuge? Ah Xin, it's not a big problem for you to have a greenhouse there. What should I do? Do you really want to take Aning and Qingxin to your place?"

"This matter is not difficult to solve. If I had realized this problem in advance, a few fill lights and a few water tanks could solve the problem before the disaster, but now..." Chen Xin hesitated for a while, But still said to Mo Qingyan: "You can try to build a large water tank to grow algae. Algae has a fast metabolism. Under the condition of ensuring light, it can release oxygen quickly, which is more efficient than plants.

　　 It just consumes a lot of water and electricity to provide sunlight. However, the city government is still supplying water and electricity, so there is no problem in ensuring the survival of the three of you. "

　　 "Raising algae? How do you do this?" Mo Qingyan heard Chen Xin say this, and she let go of her worry, and asked how to raise algae instead.

　　 "Use a grille board to raise the surface, keep the surface moist, and then continue to irradiate it with a fill light." Chen Xin was talking to Mo Qingyan, while turning on the computer to search for the information inside.

Chen Xin remembered that when he was writing a book before, he found a document about the German Ecological Experiment Building, which introduced that the Germans used algae to make the biological facade of the building, and cultivated biomass through photosynthesis, which was used for biogas production. Reaction, and then generate carbon dioxide through biogas power generation to supply the biological facade for recycling ~IndoMTL.com~ The main factor for this cycle to be established is that sunlight promotes algae to photosynthesize and reproduce in large numbers. The lights come to make up for it.

　　 But in this way, the biomass produced by the water algae for biogas power generation is definitely not enough to fill the light consumption, and it needs to supplement the energy consumption.

Fortunately, Mo Qingyan didn't cut off the water and electricity. As long as the water and electricity supply is guaranteed, if she comes up with such a set of equipment, she can still ensure the survival needs of her, Mo Qingxin and Ding Ning.

Chen Xin explained to Mo Qingyan the principle of the whole system and how to make it roughly, and Mo Qingyan also recorded everything Chen Xin said, and planned to go back and do it in her own shelter. Set up such equipment to biologically produce oxygen.

"Thank you Ah Xin! If it wasn't for your reminder, I'd have to suffocate to death to realize this problem." Mo Qingyan thanked Chen Xin and said, "You don't miss me. Wine? I’ll give you another box of gold rum later, even if I exchange these information with you."

　　When Mo Qingyan said this, Chen Xin couldn't help but feel a little surprised: "Does it need to be so clear with me?"

　　 "People say that brothers still settle accounts, even if we are brothers, it is better to be clear." Although Mo Qingyan said this with a smile, she was extra serious: "Although Axin You don’t mind if I take advantage of you, but now in this end of the world, everyone should be clear so that there will be no conflicts."

　　 Hearing Mo Qingyan say this, Chen Xin did not raise any objections. He only talked with her about whether to tell the people in the survival group before saying to her: "By the way, Dragon Mother, you help me with Alan said, that I found a survivor in a supermarket in the direction of the high-speed rail station..."
