My Doomsday Shelter Unlimited Upgrades

Although they all turned into meat in their stomachs in the end, this process is too dangerous and far less comfortable than farming.

In terms of food, Jiang Yanbing's way of life is not much different from his.

As the young lady of the Qianjin family, Jiang Yanbing claims to be good at cooking, and because of this, she can clearly identify what can and cannot be eaten.

After all, some rich or powerful people pay special attention to this. They must eat food without additives and pollution, and even refuse all delicacies from mountains and seas to protect animals, for fear of accidentally getting sick or being reported by others and ruining their lives.

It's just...

Jiang Yanbing didn't have a system as a backup like him. For the sake of safety, he avoided fighting dangerous creatures as much as possible, so he didn't eat any fresh meat.

As for hunting with bullets, this is too wasteful, and Chen Yang can understand it.

Because Jiang Yanbing has been lucky all the time, she has found a lot of canned meat. If she finds a box, she can eat it for a week, and if she finds a box, she can eat it for more than a month, so she has never tried roasting a mouse or something.

In the last days, food is also one of the most difficult things to obtain. Perhaps among people with limited survivability, rat meat is already a delicacy in the world. After all, not everyone has a system, and not everyone is like Jiang Yanbing With luck, you still have the ability to move after the end of the world.

But Jiang Yanbing never gave up on catching mice.

It's okay to catch a mouse, deal with it and store it. When canned food and food can't be found, the mouse meat becomes the last dry food. The same is true for the parasitic snake in the backpack before.

If there is always clean food to eat, the stored mouse meat can be used as bait when it is about to go bad, and the rancid mouse meat can be used to lure another mouse, thus achieving a circular effect.

Even Chen Yang had to admit that Jiang Yanbing was lucky to be able to survive until now, but his survivability was also really high. Many people would not remember this trick of recycling.

Chapter 89 Exaggerated Oxygen Production Methods (for further reading)

After dinner, Chen Yang went back to the bedroom and prepared some basic pens and paper for Jiang Yanbing.

Jiang Yanbing's job at night was to draw pictures, and he finished drawing early and got off work early, and Chen Yang didn't bother to divide the rest of the time.

While Jiang Yanbing was busy conceiving the design, Chen Yang was lying on his big Simmons bed and briefly thinking about how to make an indoor oxygen circulation system.

If you want high-quality oxygen, you can use electrolysis of water to produce oxygen, which is the knowledge taught in junior high school chemistry class.

"If calculated according to the formula for electrolyzing water, one liter of water can be electrolyzed to obtain one-ninth of a kilogram of hydrogen and eight-ninth of a kilogram of oxygen."

"I remember reading a data report before. 22.4L of oxygen is 32 grams, so one liter of oxygen is 1.43 grams."

"1000 divided by 1.43 is 700 liters, which means that a kilogram of oxygen can contain about [-] liters."

"700 multiplied by eight-ninths is almost 620..."

"One liter of water can be electrolyzed to get 620 liters of oxygen?!"

After some simple calculations, Chen Yang was taken aback.

He had never calculated these ratios in detail before. He only knew that the oxygen obtained by electrolyzing water was highly efficient, but he did not expect that so much oxygen could be obtained after electrolyzing just one liter of water.

An adult's daily breathing volume only needs to absorb about 500-700 liters of oxygen, an average of about 21 liters per hour.

That is to say, one liter of water is electrolyzed every day, and there is no need to worry about breathing for a day.

Even with the breathing capacity of Jiang Yanbing and the police chief, at most two liters of water can meet the daily support needs.

Chen Yang's breathing began to become short. This idea, which was difficult to realize before the end of the world, can be used in the end of the world.

Electrolyzed water was only commonly used in heaven before the end of the world.

That's right, in space.

In a space station or a spacecraft, no country would foolishly bring dozens of oxygen tanks into space. After all, every kilogram of things that are brought into space requires a lot of cost. Yes, so the supply of added oxygen is realized by the method of production and use, which can save a lot of weight and space.

The electrolysis of water is the most common method.

Simple and practical, no noise and no pollution, the obtained oxygen content is high and extremely pure.

But apart from spaceships, electrolysis of water to produce oxygen is not very common on land, mainly because the cost of electrolysis of water is too high.

Theoretically, it takes almost 5 kilowatt-hours of electricity to completely electrolyze one liter of water.

This is only an ideal algorithm. If you take into account the power loss and electrolysis efficiency, it will take about seven or eight degrees of electricity to electrolyze one liter of water.

You should know that the power consumption of fast-heating water heaters is only seven or eight kWh per hour.

And who's instant water heater needs to be turned on for an hour?Generally, it takes ten minutes to heat up, but even so, the electricity consumption of water heaters is a well-known thing. Even if it is only turned on for ten minutes, it will cost close to one or two kilowatt-hours of electricity.

In order to get some oxygen and spend so much electricity, the cost price is not as good as going directly to the market to buy some ready-made oxygen.

But it's different here in Chen Yang.

His sanctuary, no electricity bills!

You can use it however you want, and you can power it however you want.

The hydrogen obtained after electrolysis of water can be directly discharged into the atmosphere, which is one of the main advantages of electrolysis of water.

After the water is electrolyzed, hydrogen and oxygen will not mix together, but go their separate ways, which maximizes the purity of hydrogen and oxygen.

Many people actually have the idea that hydrogen and oxygen are obtained through electrolysis of water, the oxygen is used for breathing or sold, and the hydrogen is collected again for combustion.

Hydrogen combustion also needs oxygen, but it does not need pure oxygen, and the oxygen in the air can be used directly.

According to the law of conservation of energy, the hydrogen produced by electrolysis of water can be converted into water of the same quality after combustion.

That is to say, 1L of water is electrolyzed into one-ninth of a kilogram of hydrogen, and one-ninth of a kilogram of hydrogen is burned in the air to become 1L of water.

Repeatedly in this way, there is no shortage of water, but 100% pure oxygen has been harvested!So that the middleman earns the difference!

It's just that this middleman is not selling oxygen, but selling electricity.

The cost of electrolyzed water is much higher than the production cost of oxygen. Even if all the heat energy released during hydrogen combustion is converted into electrical energy, the oxygen obtained is not enough to be lost.

Fortunately, Chen Yang doesn't need to think about wastage for the time being.

A small loss is not called a loss!

But even so, Chen Yang didn't intend to burn the hydrogen back into water, and he didn't even have the idea of ​​collecting it, so he just set up a special channel to drain it away quickly.

How dangerous is it to ignite hydrogen gas?

No one knows better than him what it means to play with fire and set yourself on fire!

It's not a joke to accidentally blow it up beyond recognition, and Chen Yang is not short of the one or two liters of water now.

Chen Yang has not had time to solve the problem of water resources today. Now it is almost eight o'clock, and twilight is approaching. He will solve the water problem tomorrow.

Today, I installed the electricity and the second floor, planted the land, and practiced marksmanship. The work tasks have been fully arranged. If I do some more difficult tasks, I will be exhausted physically and mentally, and the quality of the work will not be guaranteed. .
