Just Developed in Mars, Rabbit Encountered Trisolaran Civilization

065 The Carbon Dioxide We Exhale Is Food.

After the start of the electromagnetic gun project.

Lu Yan was not idle either.

He was now focused on the Mars mission.

After all.

Right now, the time for rocket launch is getting closer and closer.

Since the Mags power system is an antimatter engine.

So there is no need for a large reactor, which can reduce the weight of the spacecraft.

Such words.

It is completely possible to carry resources over and build a small Mars base.

So in this regard, he has to hurry.

After coming to Zhou Whisper's Biosphere Three.

Lu Yan saw that she was crouching on the ground, as if observing something.

Lu Yan also squatted.

Zhou Wanyu felt that there was someone next to him.

Turning his head, he saw Lu Yan.

Her face instantly turned red.

"It scares me to death, you're like a ghost."

Lu Yan smiled and said, "I'm not afraid of destroying your experimental base. ”

"What are you doing?"

Lu Yan asked curiously.

Zhou Qingyu pointed to the land below, and said with some pride: "Have you seen a movie called The Martian, the male protagonist of that movie, after being trapped on Mars, survived only after planting potatoes himself." ”

"So this land is a potato cultivation system that I carried out 1:1 to replicate the Martian environment."

"So it is."

Lu Yan nodded slowly.

But he quickly thought of something again and asked: "I remember that movie, the protagonist seems to use his urine to fertilize potatoes, then aren't you..."

"Nasty!"

Zhou snorted coldly, then stood up and walked towards another place.

Lu Yan smiled helplessly.

It's nothing.

It's all dedicated to science.

He pulled out his phone and glanced at the panel.

I saw that the analysis progress has reached 99%.

It seems that today's artificial ecosystem can be analyzed.

1 hour later.

A crisp sound appeared in Lu Yan's mind.

[Parsing complete.] 】

[Congratulations to the host for acquiring technology: artificial ecosystems.] 】

Soon.

A large amount of information began to enter Lu Yan's mind.

This closed artificial ecosystem was finally mastered by him.

He came to the lounge.

At this time, Zhou Wanyu was still angry with Lu Yan, pinned his face over, and refused to pay attention to him.

Lu Yan ignored this, but said: "In a closed ecosystem, there must be at least one autotrophic organism to produce organic matter, and the waste generated by the metabolism of each organism must be available to at least one organism. ”

Heard this.

Zhou Whisper's ears suddenly pricked up.

She knew that Lu Yan was talking about the core technology of artificial ecosystems.

After a while, she came to Lu Yan and said, "Say, why don't you say it?" ”

Lu Yan smiled and said, "Don't be angry with me anymore? ”

"Less nonsense, speak quickly."

Zhou Qingyu's expression was also much more serious.

Seeing this, Lu Yan knew that her qi had dissipated, and she was now mainly experimenting.

Therefore, Lu Yan continued: "If the purpose of the system is to keep people alive in it for at least a certain period of time, the carbon dioxide released by human breathing, the daily excretion of feces and urine, etc. must be converted into oxygen, food and water by other organisms and machines. ”

Heard this.

Zhou thought softly and said: "It seems impossible to completely transform, because there is a loss of substances in the transformation process, oxygen and water conversion rate is high, and food is very difficult." ”

Listening to Zhou Whisper's analysis.

Lu Yan also agrees.

The most important problem in the construction of all alien bases is to solve the problem of food.

You know, human urine can actually be converted into clean water resources after special treatment by machines.

"Would you believe me if I said that the carbon dioxide we exhale is food?"

Lu Yan asked.

"Carbon dioxide, food?"

Zhou Wanyu asked incredulously.

Lu Yan said lightly: "Biological enzymes take carbon dioxide from the atmosphere, use the synthesized NADPH in the Carl cycle, and then release three-carbon sugars, which will combine and form sucrose and starch." ”

"So we can use carbon dioxide as a raw material, convert it into energy with solar cells, and synthesize hydrocarbons to produce starch."

Heard Lu Yan's thoughts.

Zhou Wanyu was shocked.

She also studied biology.

She understood that Lu Yan wasn't joking.

Theoretically.

Carbon dioxide does become starch.

Here.

The most important part of the artificial ecosystem is solved.

....

A week later.

Preparations for the Mars program are nearing completion.
