Half-immortal civilization

Jinxing Construction, air renovation is definitely the leading big market, and the technical content of this market is relatively low.The second is the huge space sun visor - but this thing can be produced by a master company, 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 below the height of 50 kilometers. And replace the air composition inside. At the very least, it must be done: even if the temperature is high, it can make human beings safe and free Breathe." In the huge conference room, Long Xingwang was full of energy.The success of Venus transformation made Long Xingwang climb to the pinnacle of his life.

But this meeting was a bit special, there were more than a dozen young men and women lined up beside them, the leader of these people was Zhang Chengye, and the rest were the children of high-level people.The new generation of the master company has finally grown up, and the older generation has begun to gradually move out their rights.

Zhong Yuanxing, who was already gray-haired, spoke tremblingly, "Xingwang, it would be a huge project to transform it in this way. I calculated that the thickness of Venus' atmosphere is now 130 kilometers, and the diameter of Venus is about 12600 kilometers. If the atmosphere is lowered To a thickness of 50 kilometers, even without calculating the volume fluctuations caused by changes in atmospheric pressure, it is still an impossible project.

According to the plan, we are going to evacuate almost all of the atmosphere and replace it with an atmosphere similar to the earth.Then calculated, we need to compress 21801582000 cubic kilometers of gas.

Considering the efficiency of work, it can be calculated as 220 billion cubic kilometers.This project is too large.

As far as I know, the largest compressor that technology can produce now.About 15 cubic meters per hour of compression.Of course, if we use it in large quantities on Venus, according to the current technology, if our company provides materials, it can theoretically produce a compressor unit of 50 cubic meters per hour.The cost of such a compressor unit is estimated to be about 3 million yuan, and the weight may reach 400 tons.

50 cubic meters, equivalent to 0.05 cubic kilometers; the annual work can barely reach the compression efficiency of 440 cubic kilometers.

Now, there are only ten factories on the earth that can produce such compressors, and the average output of each factory is more than one a month.We can only get 150 of these compressors at most in one year.The annual compressed air volume is 6.6 cubic kilometers.

If all conditions were ideal, it would take us about 17 years to do all the work of compressing air.certainly.This is based on existing industrial production.But even 1000 times faster.It also takes 170 years.However, it is simply impossible for the existing industrial system to improve by 1000 times.The economic technology and other conditions on the earth have been saturated.Even with the space environment.Only on an existing basis.30 times faster.And such a speedup.It will leave irreparable wounds for the development of later society.

So, I propose, the compression releases the air side.You can't just rely on the compressor.It is also necessary to find another efficient and inexpensive method.For this method, it may be necessary to find a chemist.It is a pity that the atmospheric chemistry research department of the master company is still in the future! "

Still in the future.The old expert was also arrogant.

The detailed data was enumerated, 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 more 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 at the peak of his life in his early 30s. "Considering that the atmosphere of Venus is mainly water vapor and carbon dioxide , which provides a good basis for chemical precipitation. We can sway some simple compounds or minerals into the atmosphere of Venus, allowing water, carbon dioxide and compounds to form carbonates, and it is the kind of high-temperature resistant carbonates that are insoluble in water , to ensure the normality of Venus’ atmosphere and water.

In fact, the temperature of Venus does not exceed 180 degrees now, basically we just sprinkle alkali metal ions into the atmosphere.For example, the more common calcium metal and sodium metal.These two metals use modern metals, which are easy to extract and can be obtained by simply ionizing.Magnesium can also be considered.

We can build such bases on Venus, use sodium and calcium, recycle them, continuously absorb water and carbon dioxide in the atmosphere, and then re-extract sodium and calcium by thermal hydrolysis.The separated carbon dioxide is compressed and stored; the water is discharged directly.

This plan is to detect the calcium and sodium content on Venus to see if there are resources worth developing.Otherwise, relying entirely on extraterrestrial input will cost too much. "

"Mr. Albert, I don't think it is necessary to mine minerals rich in sodium and calcium on the newborn 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 calcium that is easy to develop is mainly calcium carbonate. But in the environment on the earth, sodium chloride and trona are mainly water flow for a long time. The role of evaporation and enrichment. The distribution of calcium is very scattered, and the accumulation also requires crustal movement.

And now Venus has just undergone two rebirths, and the entire planet has melted on both sides.These things are basically difficult to exist.But magnesium is worth mining.But to explore Venus, for the mineral salt minerals of sodium and calcium, my personal suggestion is not to have too much hope.These are produced by the movement of the earth's crust after the deposition and stabilization of time. "

"I remember that there is a kind of degradable bio-glue, which 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 you discuss science, you must keep in mind: the reason why the earth exists today is that blue-green algae once multiplied on a large scale on our earth, and they absorbed carbon dioxide, sulfide, etc. from the early earth. And once let the earth At one time, the oxygen content of the atmosphere was as high as 35%.

On the current earth, there are still many kinds of life that can reproduce at a high temperature of more than 200 degrees in volcanic craters and oceans at a depth of [-] meters. There are high-temperature resistant cyanobacteria.We might be able to drop the cyanobacteria here directly on Venus.The environment of Venus is extremely suitable for the survival of cyanobacteria. It may not be long before the bare Venus will turn into a huge green oxygen.

However, the growth of cyanobacteria requires a lot of sunlight, and the space sunshade may need to be adjusted.

And with cyanobacteria, we don't need to inject oxygen for carrying out, just mainly inject nitrogen and rare gases.Even blue-green algae can be used as food for some advanced life.When the temperature of Venus drops to 40 degrees, those suitable lives on the earth can be directly put on Venus. "

The new generation is very active, and everyone is competing to perform.Beside, Zhang Chengye and others were very calm.I am investigating the authors of these people who are about to become my subordinates.

After everyone brainstormed, it was finally decided that the blue-green algae-based, chemical sedimentation and compressor units work together to modify the atmosphere of Venus. (To be continued..)
