In addition, in a closed ecology, how many species exist to be suitable for human survival is also a good scientific topic.

Scientists later discovered that although there were only eight people, there were so few species of animals and plants in Biosphere 2 that the "ecological chain" they imagined had not been established.

Of course, in addition to pure scientific research, it is also the study of human sociology and even psychology that is inspired.

For example, in various harsh environments, because of disagreements, even eight scientific researchers are divided into two gangs of four people each, and there is almost no communication and exchange between the two gangs in normal times.

But on the other hand, among the two groups of researchers who have entered the "Biosphere 2" one after another, a man and a woman have formed a husband and wife after they came out.

There are even media ridicules, in fact, this is more suitable for reality shows and TV shows for scientific experiments.

After Biosphere 2 ceased to be experimental, it was opened to visitors as a tourist attraction.

However, the investors at the time did not want to see such an outcome, so in 1996, he handed over the huge laboratory to Columbia University and invested an additional $40 million.

Later, in 1998, a paper on the impact of Biosphere 2 on the rise of atmospheric carbon dioxide concentrations on man-made oceans was published in the journal Science.

Later, people began to realize that Biosphere 2 could really make its own contribution to the field of studying the interaction between humans and the global environment.

Therefore, Columbia University at that time was ambitious, hoping to build "Biosphere 2" into a base for earth ecological experiments, scientific research, and exchanges, and invested tens of millions of dollars of its own.

However, for unknown reasons, in 2011, the University of Arizona took over Biosphere 2 from Columbia University.

It's just that no matter how it changes, the investor has never changed his original intention, and has never interrupted funding, just to maintain the power supply of "Biosphere 2", which costs 1 million US dollars a year, not including other expenses.

Today, Biosphere 2 is still open to visitors, but several research projects have been launched on the Earth's ecology and the base's life support system after the human colonization of aliens.

At that time, when Ye Fan was still very young, he saw a report about "Biosphere 2" in a "Juvenile Science Illustrated".

At that time, the feeling that Ye Fan felt was two words: shock.

Ye Fan instantly felt that human beings could really be so great.

It wasn't until he grew up later that Ye Fan discovered that this "Biosphere 2", which had a great impact on his youth, actually failed in the end.

But then Ye Fan thought about it carefully, can this experiment really be described as a "failure"?

The construction of Biosphere 2 and the start of the experiment itself was intended to prove whether humans could survive in a confined ecosystem.

Only if you survive, you can naturally prove many things, and if you can't survive, can't you prove other things?

For example, the new causes that affect the proportion of each component of the atmosphere, or the impact of the greenhouse effect on the ocean, or even the social patterns of people in extreme environments, are not all obtained through the exploration of "Biosphere 2 Good"?

"Biosphere 2" has proved with objective facts that the earth has nurtured life through billions of years of Jinhua and has become a suitable planet for human habitation

And this is precisely the reason why the Biosphere 2 experiment can be simply classified as a failure, because it makes people realize the uniqueness and preciousness of the earth's home. every day

At the same time, human beings also know the truth of finding a new home, which is not only long, but also full of ups and downs.

In the future, human beings will colonize the solar system, go out of the solar system, and face the sea of stars, such experiments must be done, and there will be countless setbacks and sacrifices in this arduous and difficult process.

What's more, there were only 13,000 square meters at that time, which was converted into 20 acres of land, and today's vegetable sheds have 10 acres each.

However, this can also be explained from another extent, that is to say, even 20 acres of land is not well managed, so how to proceed when the colony is outside the world in the future?

What's more, the larger the area, the better, taking into account the purpose of the biosphere construction, not to start a new project on the earth, but to establish an ecology on other planets, considering the space delivery capability, no material can be too much.

In addition, the research report on the atmosphere also inspired later mankind, just such a large global environmental system, the emission of 0.04% of carbon dioxide content in it will cause serious damage to the earth's environment.

Therefore, the final failure of "Biosphere 2" is an inevitability, because it cannot be played at all.

The life support system that Ye Fan exchanged from the system is actually closely related to these in many aspects, but it requires a huge amount of electricity.

The core idea is to use electrolysis of water for feeding, and to use the infinite energy of nuclear fusion to bring strong fluorescent lamps to simulate the solar environment and maintain plant cultivation.

The idea of the biosis system is not to create a complete biosphere, because that would be too complex and too expensive to implement.

The core idea is the efficient conversion of energy into various living materials, such as the water cycle and oxygen cycle with the intervention of electrical energy, as well as the cultivation of efficient crops with artificial light sources.

As for the future colonial base, Ye Fan also had preliminary plans.

After all, the precedent of failure is ahead, so Ye Fan will not use the method of building a biosphere to maintain it, but use the energy of nuclear fusion as the main energy to maintain the sustainability of survival materials.

However, Ye Fan was not reconciled to this, because the home under the cold steel and iron plate is not a real home, only with soil, sky and ecological environment, it is a real home.

Ye Fan of the "Biosphere Project" must be engaged, not only according to the ideas of his predecessors, but also use the life support system he redeemed, as well as his huge financial reserves and scientific and technological level, to create a new ecosystem.

This is not only to verify the feasibility of the artificial biosphere, but also to the viability of colonizing outer space after Datang Technology goes out of the earth in the future.

"Mr. Ye, I'm done." After the young man finished speaking, he bowed and looked at Ye Fan with a worried face.

"Do you have a team?"

"Yes, our dream is to verify the feasibility of building a biosphere in outer space, but we don't have the financial backing, so we also come here to try our luck and see if we can have investors."

"Yes, tomorrow I will bring your team to Datang Technology to meet me and give me a complete project plan of yours.

You don't have to think too much about funding, Datang Technology will contract your research expenses, 8 billion should be enough. ”

Ye Fan touched his chin and pondered for a while, then spoke.

What is a lot of money, where is this a lot of money, this is not an exaggeration!
