Venus Construction and air modification are definitely the largest markets, and the technology content of this market is relatively low. The second is the huge space visor - but the expert company can produce this thing by itself, and there is no space factory, and the production cost of the ground factory is too high.
"The first and most critical step in the transformation of Venus is to compress the atmosphere to a height below 50 kilometers and replace the air components inside. At the very least, it must be done: Even if the temperature is high, humans can be safe and free. Breathe." In the huge conference room, Long Xingwang was in high spirits. The success of the transformation of Venus allowed Long Xingwang to reach the pinnacle of life.
However, this meeting was a bit special. There were more than a dozen young men and women lined up next to it. The leader of these people was Zhang Chengye, and the rest were children of senior officials. The new generation of the master company has finally grown up, and the older generation has begun to gradually transfer their rights.
The gray-haired Zhong Yuanxing spoke tremblingly, "Prosperity, if it is transformed like this, it will be a huge project. I calculated that the current thickness of Venus's atmosphere is 130 kilometers, and the diameter of Venus is about 12,600 kilometers. If the atmosphere is lowered At a thickness of 50 kilometers, even if the volume fluctuations caused by changes in atmospheric pressure are not calculated, it is an impossible project.
According to the plan, we will evacuate almost all of the atmosphere and replace it with an atmosphere similar to that of the Earth. So calculated, we need to compress 21801582000 cubic kilometers of gas.
Considering the efficiency of the work, it can be calculated as approximately 22 billion cubic kilometers. This project is too huge.
As far as I know, it is the largest compressor that current technology can produce. A compression capacity of approximately 150,000 cubic meters per hour. Of course, if we use it extensively on Venus, according to the current technology, if our company provides materials, we can theoretically produce a compressor unit of 500,000 cubic meters per hour. The cost of such a compressor unit is estimated to be around 300 million yuan, and its weight may reach 400 tons.
500,000 cubic meters, equivalent to 0.05 cubic kilometers; the compression efficiency can barely reach 440 cubic kilometers throughout the year.
Currently, there are only ten factories on earth that can produce such compressors, and the average output of each factory is a little more than one per month. We can only obtain at most 150 such compressors in a year. The annual compressed air volume is 66,000 cubic kilometers.
If all conditions were ideal, it would take us about 170,000 years to complete all the air compression work. certainly. This is calculated based on existing industrial production. But even if the speed is increased by 1000 times. It also takes 170 years. However, it is simply impossible to improve the existing industrial system by 1,000 times. The economic and technological conditions on earth are already saturated. Even if you add the space environment. It can only be done on the existing basis. 30 times faster. And such speedup. It will leave irreparable trauma for the later development of society.
So, I propose, compressing and releasing the air aspect. You can't just rely on the compressor. There is also a need to find other efficient and cheap methods. For this method, you may need to find a chemist. Unfortunately, the atmospheric chemistry research department of Gaoshang Company is still in the future! ”
Still in the future. The old expert was also arrogant.
The detailed data was listed, which made Long Xingwang feel that he had taken it for granted. Now it seems that the compressor can only be said to be a relatively important auxiliary means.
"I remember that there was such a method in the United States." Albert IV inherited his father's business and inherited the environmental research department of Gaoshou Company. He was in his early 30s at the peak of his life. "Considering that the atmosphere of Venus is mainly water vapor and carbon dioxide, , which provides good conditions for chemical sedimentation A good foundation. We can sprinkle some simple compounds or minerals into the atmosphere of Venus to allow water, carbon dioxide and compounds to form carbonates, and they are the kind of high-temperature carbonates that are insoluble in water to ensure that the atmosphere and water of Venus of normal.
In fact, the current temperature of Venus does not exceed 180 degrees, so basically we just spray alkali metal ions into the atmosphere. For example, the more common calcium metal and sodium metal. These two metals are easily extracted from modern metals and can be obtained by simple ionization. Magnesium can also be considered.
We can build such bases on Venus to use sodium and calcium, recycle them, continuously absorb water and carbon dioxide in the atmosphere, and then pyrolyze them to re-extract the sodium and calcium. The separated carbon dioxide is compressed and stored; the water is directly discharged.
This plan is to detect the calcium and sodium content on Venus to see if there are resources worth developing. Otherwise, it would be too expensive to rely entirely on input from alien planets. ”
"Mr. Albert, I think it is a no-brainer to mine minerals rich in sodium and calcium on the newly born Venus." Zhang Fengyu expressed his opinion. As the grandson of Zhang Chen, an old scientist who explored the geological environment for the Master Company on the moon, Zhang Fengyu is also an excellent geologist.
After a short pause, he continued: "The sodium on the earth is mainly sodium chloride and trona; the easily developed calcium is mainly calcium carbonate. But in the environment on the earth, sodium chloride and trona are mainly the main components of water flow for a long time. The role of evaporation and accumulation. The distribution of calcium is very scattered, and accumulation also requires crustal movement.
And now Venus has just experienced two rebirths, and the entire planet has melted on both sides. These things are basically difficult to exist. But magnesium is worth mining. But when exploring Venus, I personally recommend not to have high hopes for the mineral salts of sodium and calcium. These are produced by the movement of the earth's crust after sedimentation and stabilization which takes time. ”
"I remember that there is a kind of degradable biological glue that can also absorb water and carbon dioxide on a large scale. Also, some high-temperature-resistant cyanobacteria can absorb a large amount of carbon dioxide." Biologist Tang Yunfu stood up, "We often ignore the power of life. . In fact, when discussing science, everyone must keep in mind: the reason why the earth is today is because cyanobacteria once reproduced on a large scale on our earth. They absorbed carbon dioxide, sulfide, etc. from the early earth and once made the earth. The oxygen content of the atmosphere once reached over 35%
On the earth today, in volcanic craters and oceans with a depth of thousands of meters, there are still many kinds of life that can thrive at temperatures of more than 200 degrees, including high-temperature-resistant cyanobacteria. We might be able to launch cyanobacteria from here directly to Venus. The environment of Venus is extremely suitable for cyanobacteria to survive. Maybe it won't be long before the bare Venus turns into a huge green oxygen.
However, the growth of cyanobacteria requires a lot of sunlight, and the space visor may need to be adjusted.
With cyanobacteria, we don't need to inject oxygen for the lift. We mainly inject nitrogen and rare gases. Even cyanobacteria can be used as food for some advanced life forms. When the temperature of Venus drops to 40 degrees, suitable life on Earth can be directly released to Venus. ”
The new generation is very active and everyone is vying to perform. Next to them, Zhang Chengye and others were very calm. The author is currently investigating these people who will soon become his subordinates. After everyone brainstormed, they finally decided on a Venus atmosphere modification plan based on cyanobacteria, with chemical sedimentation and compressor units working together.
