In space life, water is the most precious resource. It is estimated that transporting 1 gallon of water to suborbital space will cost at least $83,000.
Therefore, in order to save costs and time, the "water circulation system" was invented.
To put it simply, everyone collects the wastewater generated in daily life and even the urine and sweat of astronauts.
The toilet in the habitat cabin is a ruthless "juicing machine" that can squeeze out all the water molecules that can be squeezed out. After the feces is dehydrated, it becomes as dry as sand. The urine will also be directly dried into urea and uric acid crystals. All these will After vacuum packaging, put it into a special box marked "Hazardous Substances". If there are no accidents, these "Hazardous Substances" will be brought back to the earth.
anyway.
After the wastewater is collected, it is recycled and treated by specialized equipment. The treated wastewater is subjected to a series of operations such as distillation, separation, and filtration. Finally, it can be turned into drinking water that everyone can drink.
There is a joke among astronauts that today’s coffee is yesterday’s coffee.
But even so, the water cycle is not infinite.
A normal person consumes about 3.7 kilograms of water every day, but the water circulation system can only regenerate 3.5 kilograms of water, and 0.2 kilograms, or 200 grams, of water is lost.
200 grams of water is lost a day.
If Mark Watney wants to avoid dying of thirst on Mars, he must ensure that there is 300 kilograms of water reserve in the habitat.
Fortunately, NASA in the United States prepared sixty-eight days of supplies for six people just to be on the safe side.
They only stayed for 18 days before evacuating in disgrace, leaving only Mark Watney with the supplies for six people.
Water resources are sufficient, with 600 kilograms of water reserve.
Without considering other conditions, Mark Watney would have no problem surviving on Mars for 8 years.
Needless to say, Wu Siyuan, [Shennongjiao Space] has a lot of water containing spiritual energy.
In the movie, Mark Watney dared not take a shower for a year and a half, but if Wu Siyuan was willing, there would be no problem taking a shower every day.
Even if there is no water source in [Shennongjiao Space], Wu Siyuan's [Water Control Technique] can condense water source from the air.
Although Mars is dry, there is still water!
But humans are fragile creatures.
Dependent on water, food, and oxygen.
There is an [Oxygenator] inside the habitat cabin.
[Oxygenator] is a tool that uses carbon dioxide enriched by the fuel generator of the Mars Ascent Vehicle (MAV) to produce oxygen. Bayi Chinese website
On Mars, the most indispensable thing is carbon dioxide, which accounts for up to 95% of the air!
This is one way oxygen is obtained.
On the International Space Station, astronauts use another oxygen generation system.
It reprocesses the air in the space station and provides astronauts with uninterrupted breathable air efficiently and sustainably.
This device separates hydrogen and oxygen atoms in water molecules through an electrolysis process. Among them, oxygen is released into the air, while hydrogen is discarded into the universe.
……………………………………………………………………………………………………………………………… ………
Because there is neither carbon dioxide nor energy on Mars - there are solar photovoltaic generators that can continuously convert light energy into electrical energy, which is enough to support the operation of the entire habitat.
If that doesn't work, you can also electrolyze water to produce oxygen.
Oxygen never bothered Mark Watney in the movie either!
What bothers Mark Watney is food.
Even if NASA brings sufficient supplies, and even if the other five companions leave first and leave all the supplies to him, this small amount of food can barely sustain him for 400 days, but it will not allow him to stay on Mars for another 400 days. Survive for three years.
Because the next Mars landing will be in four years!
In the movie, Mark Watney built a space farm on Mars, used his rich knowledge of botany and agronomy, and made the most of the resources on Mars, and then successfully grew potatoes on Mars.
Including using microorganisms and bacteria in people's excrement to create soil suitable for potatoes to grow.
This process is just disgusting, nothing more.
But it was in the process of obtaining the water needed for potato growth that Mark Watney really risked his life and almost lost his life. There would be no [Mars Rescue]!
The method used by Mark Watney is to decompose hydrazine into nitrogen and hydrogen using a catalyst, and then introduce the hydrogen into a small space and burn it with oxygen to produce a chemical reaction and produce moisture.
The only problem is that hydrogen easily explodes!
As a joke goes: If a person farts in space, he is likely to be blown up by his own fart.
In a way, this is no joke.
Because there is a lot of hydrogen in human farts, and hydrogen, as a flammable gas, may explode at any time when its concentration reaches a certain level.
In the movie, Mark Watney failed to calculate the amount of oxygen he exhaled, resulting in a hydrogen explosion.
That is to say, Mark Watney, the protagonist, had a strong aura, so he was not killed by the explosion, but only suffered some superficial injuries.
The second time, Mark Watney put on a spacesuit and successfully ignited hydrogen, reacted with oxygen, and produced moisture.
Mark Watney goes to great lengths to create moisture just to grow potatoes.
The purpose of planting potatoes was just to keep him eating mashed potatoes for four years.
This is a necessary behavior for an ordinary person.
But for Wu Siyuan, there are delicacies in [Shennongjiao Space]. He can eat them in different ways every day, and it will be fine for a thousand years - if he can live for that long!
There is no need for him to be like Mark Watney and spend all his energy [farming] on Mars just to survive!
So what is he going to do?
Wu Siyuan fell into deep thought in the habitat cabin.
According to his past time travel experience, when a movie ends, it is when Wu Siyuan leaves this world.
Unless it is a comprehensive fantasy world, but there are very few such worlds, so I won’t go into details.
[The Martian] In this movie, Mark Watney did not actually have to survive on Mars for four years, but was successfully rescued by the returning Hermes in less than two years. Rescued.
In other words, Wu Siyuan can only stay in this world for less than two years.
So what will Wu Siyuan do in the past two years?
Rule the world?
boring!
It’s not that it can’t be done, it’s just that it’s not necessary!
So what does he want in this world? In other words, what do you want to get?
"Brother Shen!"
"Um!"
When Shen Changqing walks on the road, whenever he meets someone he knows, he will say hello or nod to each other.
But no matter who it is.
There was no unnecessary expression on everyone's face, as if they were indifferent to everything.
To this.
Shen Changqing has become accustomed to it.
Because this is the Demon Suppression Division, an organization that maintains the stability of the Qin Dynasty. Its main responsibility is to kill monsters and monsters. Of course, there are also some other side jobs.
It can be said.
Everyone in the Demon Suppression Division has a lot of blood on their hands.
When a person is used to seeing life and death, he will become indifferent to many things.
When he first came to this world, Shen Changqing was a little uncomfortable, but he got used to it over time.
The Demon-Suppressing Division is huge.
Those who can stay in the Demon Suppressing Division are all powerful masters, or those who have the potential to become masters.
Shen Changqing belongs to the latter.
Among them, the Demon Suppressor Division is divided into two professions, one is the Guardian Envoy and the other is the Demon Slayer.
Anyone who enters the Demon Suppression Department starts from the lowest level as a demon slayer.
Then he will be promoted step by step, and he is expected to eventually become a guardian envoy.
Shen Changqing's predecessor was a trainee demon slayer in the Demon Suppression Division, and he was also the lowest level among the demon slayers.
Possessing the memory of a previous life.
He is also very familiar with the environment of the Demon Suppression Division.
It didn't take long for Shen Changqing to stop in front of a loft.
Unlike other places in the Demon Suppressing Division that were full of chills, the attic here seemed to stand out from the crowd, showing a different kind of tranquility in the bloody Demon Suppressing Division.
At this time, the attic door was open, and occasionally people came in and out.
Shen Changqing only hesitated for a moment before stepping in.
Enter the attic.
The environment changes in vain.
The fragrance of ink mixed with the faint smell of blood hit his face, making him frown instinctively, but then relaxed it quickly.
There is almost no way to cleanse away the smell of blood on everyone in the Demon-Suppressing Division.
