People in the penal colony don’t know whether there will be an extinction-level natural change in the future. Wang Qi believes that as long as the trend exists, we must guard against it.
There is also a selfishness here.
If the will of the local world cannot be contacted through conventional means, is it possible that as long as it survives to the end, it will appear naturally?
After all, the will of the world is a thing that lasts for millions of years. He has seen countless extinctions, and being the most special group will probably arouse his "interest".
Of course, the premise is that He does have individual consciousness.
Facing the cooling channel, the Kingdom has solved or is solving problems in residential, urban, and agricultural aspects within the kingdom. The remaining two threats are not clear enough, but there are hidden dangers.
atmosphere.
There are two possibilities for the separation of the floating island and the steam sea. One is that the steam sea gradually cools down and the steam cloud layer becomes thinner. The other is that the height increases. The latter has been observed and demonstrated mathematically, while the former lacks reference objects and cannot obtain accurate data, so there is a possibility of joint effects.
During this rising process, the temperature, air pressure, and even oxygen content have changed. The so-called hidden danger lies in the oxygen content.
Taking 21% as the average benchmark, the lowest air pressure that humans can generally withstand is around 500 hectopascals. Below this air pressure, even if the breathing frequency is accelerated, it can only further accelerate the oxygen imbalance inside and outside the body.
Extreme individuals are not counted here, and the Kingdom does not have corresponding low-pressure human experiments. It can only conduct some high-altitude field observations through aircraft. Military personnel's tolerance to low pressure is not much better.
The tolerance of hybrids in the penal colony ranges from high to low. For example, strong sharp blades have a certain resistance to toxic components such as carbon monoxide, but their resistance to low pressure is not as good as that of the Night Clan. Perhaps lung volume is the key.
According to the experience of a previous life, the oxygen content does not change due to altitude, and the ratio between the surface and an altitude of 100,000 meters is basically the same.
But the penal colony has undergone a series of changes, and due to the thermal dissociation of the water beneath the steam sea, the atmosphere is somewhat abnormal.
The comprehensive oxygen content recently measured by various observation stations and outposts is 19.8%, and the surface pressure is 980 hPa.
The change in oxygen content is still within an acceptable range, mainly because the surface air pressure has dropped by more than 100 hectopascals.
People are basically indifferent until it drops to 700 Pa. The problem is that we don’t know where it will drop in the end.
Regarding oxygen, the Kingdom had a response plan as early as the floating island period, which included disaster prevention shelter mechanisms throughout the territory. The shelter has gone through several rounds of renovations and expansions, and has a magic-based carbon dioxide-oxygen circulation device and a certain amount of deodorant reserves.
But if decompression becomes a long-term event, and food production and shelter maintenance have to be maintained later, the problem becomes complicated, involving the airtight renovation of factories, farms, and underground passages.
The kingdom's economic system cannot push the large capital investment, large project volume, and resource consumption, so we can only let a few key manufacturers explore the feasibility of air-tight factories first.
In addition, decompression also comes with a new hidden danger.
Sky issues, UV rays.
People who live a comfortable life always want to supplement their UV rays, and even set up special tanning parlors.
But the nature of ultraviolet rays is very dangerous. Carcinogenesis is only a small side effect of it at normal levels. Real high-concentration ultraviolet rays are cosmic rays that are enough to destroy all protein molecular chains.
In other words, when the ultraviolet rays are high enough, the basis for biological existence will disappear.
This upper limit of the threshold is the same as the lowest oxygen content acceptable to humans. Air pressure can be used as an intermediate calibration. After all, lower air pressure means that the upper atmosphere is thinner and the number of molecules that can absorb ray energy is smaller.
Fortunately, using air pressure as a calibration object, the resistance of organisms to ultraviolet rays is better than that in hypoxic environments. Skin cancer will gradually change from accidental to inevitable at around 300 hPa.
Before the air pressure drops to this level, if everyone is still alive, they must have transferred to the disaster prevention system. The only thing that needs to make corresponding changes is the agricultural system.
This aspect is easy to say and difficult to say.
The synthetic function of plants relies on heat to provide cell vitality, and light intensity to provide synthetic energy. Ultraviolet rays are also the energy they use. They cannot be completely blocked, nor can they be used too widely.
Glass coating is an excellent solution for maintaining light and filtering ultraviolet rays. The problem is that the environment is constantly changing, and the coating cannot be removed and reapplied frequently.
Magic and underground planting solutions can also be done, but there are hidden dangers.
After people move underground, considering the dangers of coal excavation and transportation, the energy demand based on magic power will inevitably increase several times and dozens of times. If there is a way to solve the problem with engineering means, it is best not to use magic power as much as possible, otherwise The day when the magic power is not enough is the most fun.
Therefore, we still need to try our best to solve the ultraviolet problem of glass greenhouses.
Consider installing a louvered metal filter array above the glass greenhouse.
Taking into account the research cycle and final project scale, it is also necessary to find a transitional plan for light industry.
The basic idea is to use a combination of simple anti-pressure clothing and a pressurized oxygen helmet to obtain outdoor activities and work capabilities under ultra-low pressure conditions.
The specific method is to directly find a textile factory to invest money.
The Phoenix Kingdom's investment system has developed its own characteristics at this stage. Its purpose is not to make money, but to develop in a targeted manner.
There are two options for transferring money from banks to companies.
One is the basic investment model that has existed for a long time. Under this model, what companies need to repay is not interest, but fixed dividends. Depending on the industry, both dividends and principal repayment can be deferred. This is generally based on the company's equipment upgrades and expansion. Capacity needs.
The other is the R&D investment model for the cultivation of artificial edible fungi. Accepting this investment means that the R&D results will be made public by default. The company pays in intelligence and part of the R&D funds, and the benefit is that it does not have to repay the investment and can still enjoy the benefits. Exclusive domestic production rights for a certain period of time.
These two unprofitable investment methods are only available at Obsidian Bank. Other private banks with investment rights require direct investment, which will require a higher rate of return, more like general commercial investment. They mainly serve companies where the value of their own assets is not very high. Enough small business.
This time, R&D investment was also used. The light textile factory was responsible for convening small partners to conduct research. After the official received the research data, they decided at the appropriate time based on demand whether other companies needed to switch production.
Compared with all types of airtight buildings, pressure-resistant clothing is less difficult because the product form is single and there are references.
The lower the air pressure, the faster the water evaporates. If the air pressure is as low as 6,000 Pa, the water on the body surface and lungs will boil directly, and the person will die. The current air pressure in hectopascals is still close to one thousand. Even if it does drop below one hundred in the future, all kinds of air-tightening projects should be completed by then.
To deal with conditions above 6000 Pa, there is nothing special about the clothes and pants. Just use ordinary textile clothes and add rubber coating, which is enough to cope with the temperature difference and body surface pressure. If the situation worsens, you can add straps on the outside to prevent internal pressure. Expansion damage.
Considering the comfort of wearing it for many hours, it does not even need to be completely airtight, as long as it meets the requirements of heat insulation and UV protection.
Helmets or oxygen masks are more troublesome. Textile factories still can't handle them themselves and have to find other targets.
