Armor Frenzy

The work continued, and the three people had a clear division of labor. After more than an hour, seven carts of ice mines, about ten cubic meters of water ice, had been sent to the base. fastest update

Ye Han stopped working when there was still half an hour of air left, and returned to the base with the lunar rover. At this time, four hours before breakfast, it was already lunch time.

The three returned to the living cabin to take off their space suits, cleaned them briefly, and prepared to eat.

As soon as Ye Han entered the restaurant, he saw half of the group of people, and couldn't help asking curiously, "Why only half of them came back?"

Fang Xu reluctantly twitched the corners of his mouth: "People are resting and the equipment is not resting. Lao Gao and the others are still on the construction site. We will go to replace them after we finish eating."

Ye Han sat next to Fang Xu and asked with concern, "Do they have enough air?"

"We brought gas tanks. When we get to know the situation, we have to subdivide it. Four groups of people circulate throughout the day and work 24 hours a day."

Ye Han sighed: "This is really..." There is really no need to say anything, everyone understands the importance of the lunar base, and if it can be put into use one day earlier, it can save a huge amount of money and resources.

Everyone sent by the country to the moon has undergone the strictest political scrutiny. What is the difficulty of continuous construction? Not to mention that there are four shifts a day, even 24-hour shifts are fine.

Maybe the four-hour shift may not seem difficult on the ground, and even think such an arrangement is easy, but on the moon, the four-hour shift is not so simple.

The air carried by the spacesuit is used for a maximum of five hours, and a four-hour shift is a very practical arrangement.

In addition, the problem of excretion is a big problem. Although this topic is not elegant, it is an important issue that actually exists and no one can ignore it.

The spacesuit can absorb urine, but cannot handle the large size, so it is stipulated that everyone must empty the inventory before leaving the living module, to avoid the need for the large size during out-of-vehicle activities, and those with diarrhea will be excluded from the task... always can't work. Halfway through, hurry back to the living cabin to go to the toilet, right?

If there is a four-hour shift, the trumpet can try to wait until after the shift to return to the living cabin to solve it.

In addition, it is not easy to wear a spacesuit for construction. Although the gravity on the moon is low, the total weight of an astronaut wearing a spacesuit is about the same as the weight on the ground, but this equipment requires a lot of extra physical strength, even if Just manipulating mechanical equipment is not as easy as imagined.

Fang Xu also followed with a sigh: "How are you over there?"

"It's okay." Ye Han said, "The ice in this place is also quite complicated."

Yuan Yu walked into the restaurant with a plate, and everyone immediately greeted him and brought lunch to the table.

The meal at noon is very simple, rice, fish-flavored eggplant, and twice-cooked pork are still fixed.

Everyone finished their lunch in silence. After Fang Xu and the others finished eating, they immediately returned to the construction site to replace their companions. Ye Han hesitated for a while, and also called the two Xu and the two above to leave the living cabin.

The water treatment cabin is located between the living cabin and the vegetable garden. The ice cubes sent back in the morning are stacked outside the treatment cabin.

He opened the shell of the water treatment equipment to reveal a space of about half a cube inside. Ye Han glanced with his teeth and found that most of the ice cubes sent back in the first batch were too large and could not be put in at all. Put ice cubes with few impurities into the container, and then close the lid tightly.

After getting ready, Ye Han started the melting function.

This thing is essentially a large microwave oven, a device specially used to melt ice. That humble lid is actually an airtight door that keeps the pressure inside the container.

With the heating of the microwave, the ice cubes in the container gradually melt. Since there is no air pressure in the container at all, the water that has just been melted immediately enters a boiling state, and the water vapor rapidly increases the air pressure in the container, so that the newly melted water no longer boils.

After a while, all the ice was melted. At the same time as the ice-melting process ended automatically, the filter device was activated, and the water in the container quickly flowed away, leaving only a layer of sediment at the bottom.

After the water enters the equipment, it must go through several filtration procedures, and the water quality must be strictly tested, not only to detect the components to prevent harmful substances such as residual radioactive substances, but also to detect the volume and quality to ensure that the collected water does not contain heavy water.

No doubt, it is to detect the heavy water content.

The difference between heavy water and light water is very small, except that there is one more neutron in the hydrogen atom of heavy water. The chemical properties of the two are exactly the same, and the physical properties are slightly different. It is said that heavy water will not cause any abnormality when it enters the human body. Deliberate detection.

But the situation in this world is so strange that heavy water, which is completely non-toxic, actually accumulates in the body after entering the human body!

The extra neutrons in heavy water are inconspicuous, but this thing doubles the weight of hydrogen atoms, strengthens various chemical bonds, and slows down chemical reactions.

That is to say, light water will be excreted normally after entering the human body, while heavy water will stay in the body. If a large amount of heavy water accumulates in the body, heavy water will interfere with the metabolism of the human body and reduce the speed of metabolism. At that time, cells and tissues that divide rapidly will be required. There should be no exception.

Even the overbearing cancer cells will delay the spread due to the accumulation of heavy water, but the slowing down is limited and cannot be used to treat cancer.

The content of heavy water in the earth's water is about 0.02%, which will not affect the life of the earth, but the source of the water ice on the moon is a mystery. Only ghosts know how much heavy water is in the ice, and it may even be completely composed of heavy water, so it must be strictly tested. , to rule out any possible hidden dangers.

It may be unfounded on Earth, but it may directly threaten the health of astronauts on the moon.

The test results were stunned by Ye Han and others~www.readwn.com~ The heavy water content in ice mines is more than 30 times that of Earth's water!

Although 0.6% should have no effect on human beings, and heavy water can be separated out through water treatment equipment, the impact on other aspects is greater.

The moderator and coolant of this nuclear reactor are also important raw materials for the production of nuclear weapons!

After the asteroid impact event, the nuclear weapons of various countries in the world have been consumed by seven to eighty-eight, and there are few nuclear raw materials left. The demand for nuclear raw materials is unbelievable. A business that couldn't be more cost-effective.

However, the cost of launching a spacecraft from the earth is too high. As long as the moon must have a certain manufacturing capacity, a spacecraft with a very simple structure can be used to deliver raw materials to the earth.

Think deeper, the moon has no atmosphere, and the lunar base can make a deep enough hole in the ground and lay a long enough electromagnetic orbit to launch the spacecraft.

Sai Weng loses his horse and knows that it is not a blessing. The way is thought up by people. (To be continued..)r
