Chapter 448: "Biosphere" project investment

, The fastest update to the latest chapter of my super dark technology empire!
With the current level of human technology, can we truly create a world of our own?
So someone once did it. After the moon landing project, they started the most exciting scientific project called "Biosphere 2".
In 1982, at a meeting held in the countryside of the Lanxi Empire, a group of world's top scientists decided to conduct an experiment after intense discussions.
That is, to establish a closed structural space on the earth as an experimental base for the next step in the future.
The habitat after humans emigrated to Mars, the sanctuary after the outbreak of nuclear war in the world, of course, can also serve as the largest laboratory of the earth's ecosystem.
This is also the origin of the name "Biosphere 2", and "Biosphere 1" is also the earth itself where we humans inhabit.
This was a very great idea back then. The earth nurtured mankind, but now human beings have to break away from the earth and create a "earth" for them to inhabit by themselves.
In other words, humans hope that they can already be "God".
According to the design, "Biosphere 2" needs to cover an area of ​​13,000 square meters, with 5 types of terrain and forms: tropical rainforest, savanna, swamp, desert and ocean.
Not only the seawater is configured using the proportion of the outside seawater and freshwater, but also artificial machinery is used to create waves. In addition, there must be two artificial biological villages, gathering agricultural areas and residential areas.
At the same time, in order to fully simulate the real ecology of the earth, 3000 kinds of plants and 1000 kinds of microorganisms need to be placed inside "Biosphere 2".
The most important thing is that "Biosphere 2" is a closed environment composed of 8,000 white painted steel beams and 6,000 pieces of glass.
However, because the temperature difference between inside and outside will cause uneven pressure, which will damage the glass panel, there are also two variable-volume chambers called
lungs
installed in "Biosphere 2" to adjust the air pressure inside the enclosed structure. .
It's just that such an exciting gold plan is not difficult to find, and Ed Bass from Armenia, Texas eventually became the main investor.
Although the final construction cost of "Biosphere 2" has reached about 200 million US dollars, which is six times the budget, it was successfully completed in the end.
On September 26, 1991, four men and four women, a total of eight scientific researchers, were like space heroes. Under the cheers of the public and the media, they entered the "Biosphere 2" built on the 1,200-meter-high desert in Arizona. .
At this time, humans finally began to try to play a "God".
However, since the closed hatch of "Biosphere 2" was closed, everything started not going well.
According to the original regulations, within two years after the hatch is closed, nothing can enter or exit the "Biosphere 2". In other words, all the lives in "Biosphere 2" must adhere to two year.
Eight people must eat the kind they cultivated, eat circulating water, and breathe circulating oxygen.
However, here is the problem. Survival has become the only goal. The eight scientific researchers who entered the "Biosphere 2" have no other system planning progress.
On the tenth day after the hatch was closed, the accident happened.
A researcher put his finger into a threshing machine, and half of his was cut off.
Although the eight scientific researchers had received professional training before entering the
Biosphere 2
, they did not expect this to happen.
In fact, if they are truly in the natural environment in the wild, after this happens, they have only one choice, and that is to "go with the flow."
After all, this is an experiment, so a few hours after the scientific researcher was sent out to treat the wound, the "no entry or exit within two years" rule was broken from the beginning.
Over time, the eight scientific researchers discovered that this kind of thing was actually just a small thing, and a bigger thing happened because their lives were threatened.
The one threat is that the oxygen content inside "Biosphere 2" begins to drop.
This phenomenon firstly caused the seawater inside "Biosphere 2" to become acidic, leading to the death of many animals, most of which were vertebrates.
Then all the pollinating insects began to die, and the dark creatures everywhere in the building, such as cockroaches and ants, began to run wild.
Researchers are puzzled because the carbon dioxide and oxygen cycle inside "Biosphere 2" has been verified and designed many times.
However, they eventually discovered that the microorganisms in the fertilizer used to grow crops and the concrete used to construct the building have a serious impact on the composition of the atmosphere, which no one had thought about before.
Of course, the most serious problem caused by the decrease in oxygen content is the threat to human survival.
If "Biosphere 2" is a base built on Mars, then the eight warriors today will really only exist in textbooks and hang on the wall.
In January 1993, when the oxygen content in "Biosphere 2" had dropped from 21% to 14%, when all eight researchers were struggling to support it, the outside world began to decide to inject oxygen into it.
Although the eight researchers in the circle have basically achieved self-sufficiency, from the perspective of scientific experiments ~ EbookFREE.me ~ oxygen is the basis of all survival. If oxygen is input from the outside, then this experiment has basically It can end with failure.
On June 26, 1993, after stubbornly surviving for one year and nine months, seven of the eight researchers who entered at the beginning chose to step out of "Biosphere 2", even though it was only two years away from the originally agreed time. For three months.
On March 6, 1994, the second group of residents consisting of five men and two women entered Biosphere 2 again, but this time the carbon dioxide concentration in the atmosphere was out of control, so they only stayed for ten months. Evacuate in a hurry.
So far no one has ever lived in "Biosphere 2".
Later, from "human feat" to "luxury science", in fact, the media trend at that time changed very quickly.
Many people even began to reflect on what such an expensive experiment has brought to humans.
There is actually a little bit.
For example, the imbalance of the ratio of oxygen to carbon dioxide in the atmosphere in the circle is a very valuable lesson.
