"The liquid pipelines in the three areas have accurate nearly 1,000 water points, and these water points have independent water outlet systems to ensure the overall stability of the three major water source areas, which are the sources of drinking water."

"The other part of the domestic water has a complete wet control equipment, sewage and wastewater recycling and treatment equipment, ......"

"There are more than 7,500 humidity control devices on board the Tissot that detect the humidity in the current area and collect excess moisture in the air for conversion ......"

"In terms of wastewater, there are 24 sets of sewage and wastewater treatment equipment that integrates dewatering and filtration, which can highly strip clean water and leave behind the dehydrated organic matter, which can be used as soil fertilizer in the plant area, which will be a very good recycling ......"

"These wastewater treatment equipment are currently the world's top-notch, filtered water, up to a very high standard of hygienic drinking, and at the same time, after dehydration, the organic matter is like dust, almost no strange taste......

Edward spoke eloquently.

Chen Mengchuan listened to his detailed introduction with a smile, and then went with him to the life support system project team, which was the first large group to be established, and Edward was also one of the team leaders.

Chen Mengchuan communicated with everyone and discussed many ideas in the universe, not only fantasies, but also many realities. A lot of it was read directly from NASA in the United States through a more powerful spider web system, and after being screened and filtered by Kawachiko, all of them were very essence knowledge systems.

For the survival of human beings in space, the project has been simulated many times, and there have been several activities to build and test the cabin. During the test, many, many testers were placed in a confined space with nearly 100 species of plants and a large number of complete life support systems, providing all water and oxygen needs through recirculation, and successfully completed the tests on cabin hygiene, sleep, nutrition and work issues.

And the researchers of the project team have studied in great detail the psychological effects of people living in a completely monitored and isolated environment and the changes in human rhythms, which is a very important and necessary test.

In addition, the nearly 100 species of plants grown in a completely confined space have also attracted much attention.

In the test environment, a large proportion of the most important sources of essential substances such as food, water and oxygen are plants. A total of 96 species of plants are planted in the 10 biological cabins in the test chamber, and this large area of green is very vibrant in the fully enclosed test environment, and the 10 biological cabins in the entire area are completely equipped with high-tech vegetable planting base technology.

Among them, lettuce and rape are the largest and most important green leafy vegetables, and a large number of green leaves were produced in a short test period. In the 21 days of the test, according to statistical data, 10 biological cabins received a total of more than 900 kilograms of fresh fruits and vegetables, which passed the test perfectly.

In the animal area, fully enclosed fish farming and poultry farming also passed the test in a test environment.

For the scientists participating in the test, there is no need to worry about the food, and the oxygen is completely sufficient.

These test data and test results are very encouraging. Judging from the data, Chen Mengchuan believes that when the Tissot is really in the sky, the current biological recycling and transformation technology will be enough to make the Tissot self-sufficient, and at the same time, all people can eat enough fresh food.

For the whole morning, Chen Mengchuan and Zhao Wanyu stayed in the biological circulation transformation department, and ate the food provided by the test area with the scientific researchers before leaving.

Zhao Wanyu sent Chen Mengchuan outside the gate of the space travel department, and then turned around and left directly, in one morning, she would accumulate a lot of work, and she needed to deal with these jobs as soon as possible.

Chen Mengchuan, who was in a much better mood, was seen by Toni with a happy look after returning to the space travel department.

"It looks pretty good." Toni asked him with a smile.

Chen Mengchuan nodded: "In the morning, I went to the biological recycling transformation project department with Wanyu. ”

"How's it going?" Toni asked succinctly.

"Don't you know by looking at my expression?" Chen Mengchuan replied with a smile.

Toni nodded: "The last time I met Edward from England, if I remember correctly, he is a senior applications consultant at NASA in the United States, and almost all of NASA's capsule piping designs are from Edward's team. ”

Chen Mengchuan smiled: "Wanyu dug down their entire team. ”

"Is money really everything?" Toni smiled.

Chen Mengchuan shook his head: "Of course not, his current identity is naturally not short of money, and the higher value embodiment of life is the pursuit of a higher level." In principle, he is the same kind of person as you. ”

"You guys? You don't include yourself in this vocabulary. ”

"My words, I just want to better protect myself, protect my family and friends, that's all." Chen Mengchuan smiled.

Toni rolled his eyes: "Is there no boundaries?" ”

"Haha, I love that word."

Time passed very quickly, and a whole week passed, and when the theoretical demonstration of the space travel department was nearly 50% completed, Zhao Wanyu came to take Chen Mengchuan and Toni and several other core members to the gravity department to accept the technical report.

"Multigravitational technology has been perfected?" Toni was a little surprised.

Zhao Wanyu smiled and nodded: "The multi-gravity technology in a single space has also been basically realized. ”

"Just check it out." Chen Mengchuan directly waved his hand, and a group of people took a few gravitational balls and flew directly to the gravitational department.

The Gravitational Department has now moved into a new super-large laboratory, almost the same size as the Space Travel Department. The gravitational deep research technology department occupies a large area of indoor space, and the gravitational application department occupies a broader outdoor experimental area, and the two departments cooperate more closely.

By the time the group arrived, the advanced application of the multi-gravity technique had been completed, a very large grid metal sphere!

"Chen! You're finally here. Puslin greeted him with a laugh, looking in a very good mood.

"Long time no see, Puslin, you seem to be in good spirits." Chen Mengchuan greeted with a smile.

"It's been a long time since I've seen Puslin......" and the group also greeted him one after another.
