Agriculture is the foundation for the development and transformation of the planet, and it is not possible to rely on the support of the earth, and the small space has too much food to grow and the sky is too busy, so in the process of transforming the red giant, it is very necessary to build a number of agricultural facilities first.

It's just that without the help of Tianming's ability throughout the process, the work progress of those staff members is very slow.

Han Lei explained: "Commander, the area of the agricultural base is 3,000 acres, and it is necessary to build a 6-kilometer-long fence and build a large number of indoor cultivation room walls, which is a very large workload, but there are only more than 3,000 people who can be freed up in the base...... If you want to go faster, you need to bring more people from outside. ”

There are now 19,000 people in the Red Bank base, which is basically full, and then get people in, how to place those people will take a lot of effort, and the material consumption will increase a lot, Tianming is troublesome, his idea is to make the first complete dome space first.

"I'll help you, it's better to have all the facilities built in three or five days."

Tianming asked the staff in the dome space to stop what they were doing, and when he stepped aside, he began to get busy.

Under the guidance of agricultural experts, it took two or three hours to build an agricultural base of 3,000 acres.

The agricultural base adopts a three-dimensional multi-layer cultivation method, using soilless cultivation technology, on a pillar and in the nutrient pool, growing melons, fruits and vegetables, and the intensity of the star shining on the red giant star far exceeds the earth's sunlight, which can make these fruits and vegetables grow for a long time, plus other measures, one acre of land can produce enough food for 10 people to eat, no problem.

In addition to the agricultural base, there are also living and living facilities for people.

After a while, Tianming built 1,000 houses.

This kind of house is very strange, made of pure silver and steel. It has 10 floors and is 30 meters high, shaped like a pagoda or "pyramid", thin at the top and thin at the bottom, from the bottom to the top, through guò a corridor that hovers outside the house (like a winding road), the internal facilities of this kind of house are very simple, there are only water supply facilities inside, the water is flowing down from the water tower on the roof, and the electrical equipment has to be installed by itself.

This kind of house is called "tower house" by Tianming. A tower house can accommodate about 50-100 people, and 1,000 buildings can accommodate more than 50,000 people, and the problem of living people is basically solved.

In addition, factories and research institutes should be built, such as power plants, brick factories, materials research institutes, equipment research institutes, etc., all of which should be designated for the construction of these buildings...... Dawn had limited time, and it would take him a few days to complete the work.

……

Inside the Red Bank base. Base 9 space.

This is the Air Purifier Research Institute.

There are about 600 experts and engineers in this research institute, and most of them were brought over from the National Defense Liudun Base by Tianming some time ago, and the main purpose is to develop air purifiers.

Shao Jinxian, director of the research and development institute of air purifiers. Chief designer, he has more than 30 years of research experience in the field of material purification, and has had exploratory research in the field of alien atmospheric environment modification for a long time.

He said to Tianming: "Commander." The main components of the atmosphere of the red giant are nitrogen, carbon dioxide and hydrogen, and it also contains small amounts of rare gases such as helium and argon, and trace amounts of oxygen and water vapor. If you ignore the difference in content, the main ingredient is actually similar to that of the earth. Moreover, we have also found a content of 1 part per 100,000 of methane in the atmosphere of the red giant, and this planet, there is no active volcano in an eruptive state, and the important reason for the appearance of methane may be the presence of microorganisms on this planet. ”

Generally speaking, methane is an important evidence of whether there are microorganisms on a planet, because methane is synthesized by microorganisms in the process of maintaining life, using hydrogen and carbon dioxide to react, if there is no volcanic eruption on a planet, then methane is very likely to be synthesized by microorganisms.

However, Shao Jinxian can't be completely sure whether the red giant really has microorganisms, after all, for so long in the past, no one knows whether the volcano of the red giant has erupted, and a little methane appears, which is nothing particularly unusual.

"Forget about the microorganisms, can the air purifier work to clean the atmosphere of this planet?"

"Yes, it can purify most of the harmful air, but the purification efficiency is not particularly high, and it needs to be improved."

"What do you want to improve?"

"The main thing is the design of the filter device, we have designed a new filter device, the filtration efficiency is 70 times that of the old filter device, the specific structure is like this...... Only you, the Commander, can make such a device, so do me a favor. ”

The working principle of the air purifier can be described by two words: "simple", it uses a nuclear battery as an energy system to provide energy for the heating furnace, the wall material of the heating furnace is heat-resistant black steel, and the temperature can be heated to more than 4000 degrees, and in special cases it can be heated to 6000 degrees.

The high temperature of 4000-6000 degrees is enough to heat any molecule to the point where the chemical bond is broken. In high temperature, all substances become elemental, and then through layers of filtration devices, carbon dioxide, hydrogen, methane and other gases in the atmosphere of the red giant star can be separated and turned into elemental C, hydrogen and oxygen, and elemental C and hydrogen are stored in the purifier, and oxygen can be directly discharged into the air, increasing the oxygen content of the atmosphere, and finally increasing to a concentration suitable for human direct survival.

Tianming quickly built a new filter and installed it in the air purifier.

"This purifier is working now, right?"

"Yes, it should be."

"Okay, you all change into spacesuits, and I'll take this machine to test outside."

Outside the base, the Red Giant Star Table.

Tianming took out the "air purifier" that looked a bit like an enlarged version of a hair dryer and placed it on the ground.

Shao Jin first debugged with more than a dozen researchers, pressed the start button, and the machine began to work.

Buzz.

One end of the hair dryer sucks in the gas, the other end releases the gas, Tianming put his hand on the end of the gas outlet to feel it, the purified gas is still hot, just out of the pot fresh air.

"Lao Shao, how is the purification speed of this air purifier? If you want to purify the atmosphere of this planet, how many such machines will be needed? ”

Shao Jin pondered for a moment and replied: "It will take at least 100 million units and a hundred years of uninterrupted purification before it is possible to complete the purification of the entire planet." ”

Tianming's eyes widened, "100 million units!" This amount is too large and the time is too long, is there a way to shorten the time and reduce the number of purifiers? ”

"Yes! That is, to build a super purifier that is 100,000 times larger than this purifier, the size of a mountain, and use a high-power nuclear power plant to supply energy, and the purification speed will be much faster. ”

"Well, such a large purifier can't be made in a while, so this small purifier should be used first."

Buzz.

After an hour, the air purifier stopped.

"Why did the machine stop? Go ahead and purify it. "Tianming Dao

"No, Commander, the carbon storage box and hydrogen storage tank in the purifier are full, and if you purify it, there will be no place to store the excess carbon and hydrogen."

"No, it's only a moment before it's full, I'll see."

The function of an air purifier is to separate excess and harmful substances in the air and store them in their own storage device. Tianming saw that the large carbon storage box under the purifier was full of fine elemental carbon particles, and the hydrogen storage tank next to it was also filled with a whole tank of liquid hydrogen.

"What happens to all this excess carbon and hydrogen after the air is purified?" Tianming asked.

If it is burned as fuel, the oxygen content of the red giant star that has finally increased is estimated to drop again, which is equivalent to not purifying.

Therefore, these purified residues must be disposed of in a suitable way.

Shao Jin said first: "Commander, if you want to purify the atmosphere in the later stage, the carbon and hydrogen produced will only increase...... I think we could build an oil synthesis plant in the dome space and synthesize oil from the excess carbon and hydrogen. Oil is of great use to us, not only as a fuel, but also as a raw material for a large number of industrial products. ”

Oil is the blood of industry.

All aspects of people's lives are inseparable from oil, in addition to the fuel used in airplanes, ships, and automobiles is produced by petroleum cracking, and it is also the raw material for many chemical industry products such as solvents, fertilizers, pesticides and plastics, etc., and people are enjoying the convenience brought by petroleum products every day.

Hearing the word "oil", Tianming's eyes lit up, good thing. If the excess carbon and hydrogen are not easy to deal with, then the synthesis of petroleum is indeed the best solution.

Tianming said: "After a while, I will introduce a set of petroleum synthesis equipment from the state to produce oil!" ”

……

In the next period of time, Lan Luo was busy with the formation and management of the three companies, and Tianming himself stayed in the red superstar for half a month.

In the past half month, the results have been remarkable.

He first went to Blue Mercury and extracted 20 million tons of seawater, which were stored in two super-large silver steel tanks, half of which he made into a nutrient solution suitable for plant growth, and the other half of the seawater, which was desalined and turned into drinking water for the people in the base.

The dome space has basically become a dome city.

The agricultural base inside was planted with the first crop of fruits and vegetables, and the factories of various factories and research institutes were also built, including the oil synthesis plant...... In order to obtain petroleum synthesis technology, Tianming paid the price of bringing in another 2,000 national experts...... In fact, it can't be regarded as a price, in a sense, these experts are also working for Tianming, and he is short of manpower.

……

On June 25, Tianming, who had gone on a "business trip", returned home.
