China Entertainment King of Science Fiction

Chapter 397 Growing potatoes is so exciting

"The useless knowledge has increased again..."

This is the feeling in the hearts of many viewers.

Even for a self-proclaimed hardcore science fiction fan like Ding Wei, it is too hardcore.

The theater where Wu Heng and Ding Wei were in was a movie fan hall. This was Wu Heng's request for premiere tickets at the time. He always felt that the atmosphere was not warm enough for film critics, reporters and even industry professionals to gather together to watch a movie.

Younger film critics are okay, but those who are older and come from the fifth generation of directors do not appreciate science fiction movies so much.

For them, realism is serious and is the superstructure of film art. Non-realism is entertainment and a live-action version of fairy tales, so it is naturally inferior to others.

Needless to say, in the industry, even if you are really attracted by a movie, you will be stingy about expressing it publicly, so the screams, exclamations, and laughter are usually caused by fans at the premiere.

The general audience attending the premiere of "The Martian" this time were mainly fans of Chen Jingxing's movies, or space fans, or science fiction fans.

DreamWorks and the Space Administration News and Publicity Center jointly organized China Aerospace’s “Chasing Space Dreams, Building Space Dreams” science popularization activities, including online knowledge contests and science fiction submissions. The selected space fans, space fans, and

The lucky audience members who were drawn were given tickets to the premiere of "The Martian".

Therefore, there are many hard-core science fiction fans and aerospace fans like Ding Wei in the theater. Many of them are aerospace enthusiasts and keyboard warriors in Tieba forums.

Use the habitat's atmosphere regulator.

That means... there is a lot of unburned hydrogen in the air, everywhere, mixed with oxygen, and then... just an electric spark can blow up the habitat cabin.

Lei Jiayin was a bit embarrassed to show off his chatter in front of the camera. Perhaps being on a planet where he is the only one, constantly recording video and audio logs will prevent him from being overwhelmed by fear and keep him alive.

of optimism.

Chemistry is a slippery subject, and some ammonia is destined to remain in an intermediate state without reacting with hydrazine.

There's just one challenge: breaking the hydrogen out of the hydrazine.

On the big screen, after calculating the farmland and expected harvest, Lei Jiayin immediately had to solve the next problem.

Lei Jiayin, wearing a space suit lining, gloves and short boots, an oxygen mask and laboratory goggles from a chemical tool box, cheered in the "farmland".

Therefore, the only reason for the "positive" increase in oxygen is that it consumes less than I thought. However, the hydrazine is actually used up in the expected amount.

For these confident space fans and science fiction fans, "The Martian" becomes completely beyond their imagination as the protagonist begins to survive.

The audience gradually becomes involved in the plot, breathing and sharing the fate of the protagonist. On the one hand, more importantly, there is nothing for them to learn or even criticize.

I can perform the above operations repeatedly and burn out all the hydrogen in the habitat cabin through controlled injection.

Get some hydrogen, add some oxygen, and burn.

This way I can do whatever I want in my spacesuit without having to worry about exploding.

Ugh...the smell of ammonia is unpleasant!"

As long as I can let the habitat module power the fuel station, it can provide me with carbon dioxide at a rate of half a liter per hour, continuously. After 10 Martian days, I will have 184 liters of carbon dioxide, and then use the oxygenator,

Can produce 184 liters of oxygen.

Yay! Oxygenator!

There is only one problem: the Martian atmosphere is extremely thin, with only 1% of Earth’s atmospheric pressure, making collection work difficult.”

For some men in science and engineering, showing off knowledge is a completely uncontrollable instinct like a peacock spreading its tail.

It must be that a lot of hydrogen produced did not participate in combustion and floated into the air.

This is enough to make nearly 600 liters of water! Far more than needed!

"I could use tape to block eight vents, leaving only one working, and then use the suit's oxygen tank to fill that bag with pure oxygen, connect the vents, and trick the regulator into letting it move the habitat The oxygen in it is extracted.

Then use an oxygen tank to inject a small amount of oxygen into the hydrogen, and then use some batteries and wires to create micro-sparks, which can ignite the hydrogen immediately, and the amount of combustion is limited by the amount of oxygen injected.

Lei Jiayin, who had been hiding on the rover for a day and a night, once again came up with a solution.

The only reason this soil is called active soil is because there are bacteria growing in it. Once I remove all the oxygen, the bacteria will die..."

Each cubic meter of soil requires 40 liters of water to meet planting requirements. Lei Jiayin's entire plan requires 15.5 cubic meters of soil, which works out to a total of 618 liters of water for irrigation.

Lei Jiayin planned to keep 50 liters as spare and use the rest for watering, but it was still not enough, with 368 liters of water still missing.

"Then we can only focus on the atmosphere of Mars. The atmosphere of Mars contains 95% carbon dioxide. As for me, I happen to have a piece of equipment that specifically decomposes oxygen from carbon dioxide.

Apparently Lei Jiayin also realized the danger immediately. He immediately waved a ziplock bag in the air a few times, then sealed it, dressed neatly, exited the cabin and entered the rover. The atmospheric analyzer analyzed it and found that the nitrogen content was 22%. , oxygen 19%, hydrogen 54%.

"My teammates left on the Mars launch vehicle rocket, but its lower body remained in place.

But the happiness didn't last long.

Lei Jiayin finally figured out a way to overcome the danger of the habitat capsule exploding and use up all the hydrogen.

And this involves the Mars landing vehicle. The landing vehicle rocket has saved reserve fuel, 292 liters of unused hydrazine.

The habitat becomes a dangerous "hydrogen tank."

Hydrogen is deadly because it explodes.

The regulator has four independent safety interlocks to ensure it does not allow the oxygen levels in the habitat to drop too low, but the regulator is designed to avoid technical failure rather than vandalism.

Obviously, the bravery, perseverance, wisdom and optimism of the hero played by Lei Jiayin have successfully infected all the audience. This is the favorite character of the science fiction fans and space fans in the theater, and it is also their favorite plot.

If you want to make water, you have to start from scratch.

Some people in the audience in front of the screen whistled and even shouted.

In a series of dizzying operations, he successfully produced water.

There is a lot of oxygen reserve, but it is far from enough to produce 368 liters of water. There are two high-pressure oxygen storage tanks in the corners of the habitat cabin, and these reserve oxygen can only produce up to 100 liters of water.

Therefore, the auditorium presents a gender ratio in which yang is strong and yin is weak.

But if they are really used up, Lei Jiayin will have no oxygen for extravehicular activities, and there will be no emergency oxygen preparation. This is a dead end.

Lei Jiayin, who once again solved the problem, took the same soil that had gone through many hardships and made it into a slide. With trembling hands, he put the slide into the microscope and called up the image on the screen.

In this way, I will have enough oxygen to produce 368 liters of water, and the oxygen will be released."

The plot of "Mars" is that problems constantly arise, making the audience's heartstrings tighten, and then the protagonist constantly comes up with jaw-dropping solutions, making everyone feel uncomfortable.

It’s true that I am a botanist, but I also have perfect scores in chemistry.

Under the unclear eyes of the audience, accompanied by brisk music, Lei Jiayin began a series of dazzling operations.

There is little water on Mars, there is some ice at the poles, there is ice on Olympus, and there may be water in the porous rock underground, but it obviously does not help.

And this kind of whispered exchanges becomes less and less as the plot of the movie develops.

After solving the problem of oxygen, the next step is hydrogen.

Every line, every choice, and every action contains full of science and rationality.

Anyone who often goes to the cinema must have encountered someone who talked endlessly about popular science knowledge with his girlfriend or fellow moviegoers during the movie screening.

The only reasonable explanation: I didn’t burn all the released hydrogen!”

Lei Jiayin found that the water produced was not as much as he imagined.

Wu Heng's heart that he had just let go of soon became tense again. Although there are no action scenes, the narrative rhythm of this movie is so dense that it is difficult to distract.

water.

Lei Jiayin seemed to be recording a diary, but also thinking with the audience behind the camera, thinking calmly: "My oxygen is increasing, and the amount of gas introduced from outside the cabin is continuous.

The main function of the regulator is to reduce the oxygen concentration.

The habitat cabin has the best water circulation device, which is the best equipment that can be built on earth. Human beings need 3 liters of water every day to live healthily, so the space agency has only prepared 50 liters of water for each person, which means

, there are 300 liters of water in the habitat cabin.

The final result is that five molecules of hydrazine can produce five molecules of nitrogen that is harmless to humans and animals, and ten molecules of hydrogen. During this process, there will be an intermediate process of converting it into ammonia.

There's just one flaw: it will ruin my fields.

Although there are no visual spectacles, the rich amount of hard-core information across multiple disciplines creates a kind of brainstorming. Questions and surprises one after another make the audience breathless, and in disguise realizes a narrative without peeing spots.

Even half of what was booked.

The plot, which was already on the right track and showed hope, once again took a turn for the worse and reached the edge of the cliff.

Each hydrazine molecule contains four hydrogen atoms, which means that each liter of hydrogen in hydrazine can make two liters of water.

So the auditorium for the premiere of "The Martian" must be the place with the highest density of people.

Ding Wei followed the actor's train of thought: "Damn it! It's dangerous!"

Once the habitat capsule explodes, the male protagonist will no longer have any chance of survival.

Just like Ding Wei's science popularization of "Mount Olympus" at the beginning, many science fiction fans and space fans continued to exchange their own opinions with people around them or popularize the knowledge they discovered from the movie after the movie started.

However, the male protagonist of "The Martian" is indeed the "most powerful" protagonist he has ever seen.

"What I have to do is react it with a catalyst that I can extract from the engine of the landing vehicle rocket, and that creates nitrogen and hydrogen.

Remember how liftoff rockets used the Martian atmosphere to create fuel? The first step was to collect the carbon dioxide and store it in a high-pressure vessel.

But the prerequisite for it to explode is that there is oxygen in the air. Without oxygen and hydrogen, it is basically harmless.

Let’s start with oxygen.

They're still there! The healthy, active bacteria are just as busy as ever!

Can grow potatoes!

As excited as Lei Jiayin were the audience who were immersed in the plot.

Wu Heng let out a deep breath, "Good guy, he never thought that just planting potatoes in a movie could be so exciting."
