Superman, Man of Steel, Female, 6 Years Old!

Because Anna and the others only need to do this once.

Then the few of them can get the favor of the world and more source power continuously from the source power of the world.

So there is no need to make more choices, among the two options provided by scientists.

Anna focused almost all of her efforts on tackling key problems, which is the most suitable technology for her and Caichuan's vertical farm.

As for the low-cost rotational planting solution born in Singapore...

This is really only suitable for Singapore, and areas with sufficient sunshine like deserts.

Even in Anna's magic building, there is a free small solar light source that can be used, but the waste of space caused by its low output, coupled with the labor cost in the planting process, is also a big problem for Anna. troubled.

Especially in Anna's high-tech farm of the latter type, after she can use all means to save costs, the low-cost advantage of the rotation planting scheme is lost a little bit during construction.

Of course, the first solution is not useless to her.

How to say it is also a vertical farm technology that can grow ten times the output of traditional agriculture at the price of one cabbage.

Therefore, although it is not suitable for promotion in small magic buildings, places that are extremely concerned about space utilization, but in places where there is no need to care about wasting space at all, such as the Sahara Desert on Earth where there is plenty of sunshine...

This is good for Anna to grow staple foods such as wheat and soybeans that don't require too much care.

Especially after the electricity is connected to the Ark reactor, one reactor can drive hundreds of square kilometers of tower planting.Then the cost will be lowered directly to the ground.

You must know that this rotary planting technology requires a water pump, some shelves, planting tanks, chains, and a large glass greenhouse.

For Anna, the cost of these things is almost no cost.

Because she can smelt the metal she needs, burn the glass she needs, and make the motors, pipes, and pumps herself.

Even the transportation costs to the desert area, the dragon cranes like her and Thor can also be transported by themselves.

A small van that can hold tens of thousands of tons of steel flies past at 5 times the speed of sound...

What kind of transportation costs are diluted to zero.

This kind of cost is so low... Even if it is used to grow staple foods such as wheat and rice, it can still make her a fortune.

As for the human cost of sowing and harvesting...

This one, too, will be incredibly low, too, after machines designed specifically for planting and harvesting with workers driving back and forth between the frames.

Because this thing can be made by Anna alone.

Even if human beings run away in the future, this rotational planting technology can also be used in space in the future, where space is not too important and human resources are not so scarce.

……

……

State-of-the-art farming techniques are not out of the box.

In addition to converting the technology of those commercial companies into the power supply of the Ark reactor, Anna's new brothers also had to increase the height of the vertical factories that were only a dozen meters high to a height of one hundred meters in the floor space.

After installing various sensors, conveyor belts, and robotic arms, Anna and the others had to think of all ways to reduce construction and maintenance costs.

Although there is robot technology in this world, compared to Anna who can rub out the mechanical arm of the Iron Man with Mai Mai with bare hands, the level of this world is far behind.

And even in terms of cost, the average cost of each industrial robot in Japan is about 300 million yen. Of course, among the simpler agricultural robots, the cost of more than half of the agricultural robots is lower than this 300 million yen. much cheaper.

However, if Anna produces the robotic arm herself, the cost can be reduced to one-tenth of that of several major Japanese manufacturers.

There is also a huge amount of LED planting light modules, which is a huge expenditure other than the mechanical arm for the scale of Anna's farm.

So if she wants to minimize costs.

Then Anna and the others have to buy a small robot factory and a small semiconductor factory, and directly reduce the two major expenditures for the construction of the entire high-tech farm from the source of production.

And after receiving the order for entrusting scientific research, those scientists didn't come to grow vegetables for Anna with their own funds.

So in the first stage, she has to run two new types of farms with different costs in different environments on the earth.

In other words, except in his own magic building.

Anna still has to test the effects and feasibility studies of two kinds of farms in the Sahara Desert, in the Antarctic and North Pole, in the center of the Pacific Ocean, and in these places hundreds of meters underground.

And it's different from a commercial company.

They also have to study how various staple foods such as wheat, rice, soybeans and potatoes are grown in these places.

And after the second stage.

The commissioned scientific research project also required Anna and the others to build a giant outer space standard agricultural module with a regular hexagonal cross section, a side length of 400 meters, and a length of 1000 meters above the earth's outer space orbit.

In the eyes of human countries at this stage, this giant farm that looks like a giant has generated gravity by spinning. This standard space agriculture module, in addition to requiring that various kinds of food can be grown inside, it also needs to Be able to keep livestock in it.

Even at the last moment.

This space farm has to become a small, enclosed mini-Earth biosphere that requires the least external supplementary materials, has the lowest energy requirements, and is also the most sustainable.

Chapter 271 Chapter 269 Things You Don’t Need Even If Everyone Knows It

In the end, countless real "Noah's Arks" in outer space will be produced to solve the food problem of human beings in the future. This is the ultimate goal of the project commissioned by the United Nations.

And the reason why Anna defeated a lot of scientists on the earth, as well as a lot of commercial companies, got this scientific research project that has been going on for decades.

the most important reason.

Except for the floor space of the vine version of the biological battleship, which is now only owned by Anna and the others.

It's the ability to build giant space farms in outer space...

Without the guardian's action, only the current Anna and his party can do it.

Otherwise, based on the current technological level of ordinary human countries, a 440-ton international space station has spent 20 years, and the cost of launch, construction and operation has already cost as much as 1600 billion US dollars.

If several major countries are really required to provide launch and construction costs for the planned huge space farm facility, then the money may cost more than trillions of dollars.

And when it comes to Anna...

The regular hexagonal giant space farm with a side length of 400 meters and a length of 1000 meters, in addition to the 100 scientific researchers assigned to her by the United Nations, even the entire project funds are only a mere 100 billion. So many dollars.

Mostly, because the total weight of the giant space farm may reach hundreds of thousands of tons, Anna was allowed to go to countries like Australia and Chile to mine mines for free.

Although the ore also costs money, no matter what country it is, this space farm is really a free gift like a super Chinese cabbage.

……

In fact, it is not uncommon in this world to cheaply launch materials into outer space. Even the guardian of Oborozuka, Mado Futsu, can use magic to directly get satellites into the sky.

As long as their ability reaches a level similar to Thor's, it won't take them much trouble to launch a satellite in the sky or something.

The cost may be the middle-aged old man going home to sleep, or adding two steamed buns to his meal.

However, if a high-energy creature at the level of a guardian is compared to ordinary human civilization, it belongs to the level of a star-level civilization.

Before the Great War 20 years later.

Or before the United Earth Government was established.

It is impossible for a means of this level to be sent down by the guardians to a country formed by ordinary humans.

Just like Anna's current Ark reactor, although the guardian and the three new gods all know this technology, they also acquiesce in her using this technology in her own place and company...

But except for the human country that has overcome technical difficulties by itself.

Otherwise, this technology of controllable nuclear fusion will have nothing to do with them before it is taken over by the United Nations.

The reason why it is like this...

In fact, the three new gods and guardians do not want human beings to easily master revolutionary new technologies in order to form dependence on them.

And they don't want human beings to inflate their self-confidence after picking up the super technology of controllable nuclear fusion, which will affect the establishment of the unified earth government 20 years later.

Basically, it is this kind of technology that can make civilization leap forward. Unless it is researched by the human country itself, the Guardian will not provide it to ordinary people until the community of human destiny is formed and the unity of mankind is formed.

It's like Anna used the price of cabbage, 100 billion US dollars to build a giant farm for humans in space...

All the added value generated after its completion, as well as the innovation of science and technology in space, can only be enjoyed after it has fully joined the United Nations system.

The same goes for the technology of super armor, vans, and drones that Anna spread to those human countries before.

Although these countries can produce, they can also use it.

You can even take the produced things to the laboratory for research.

But the UN's supervision and restrictions on these things are very strict.

Because Anna was requested by the guardians from the very beginning, in the quantum codes of those diffused super equipment, there are directly hidden many backdoor control methods...

If it is necessary, for example, when those countries want to wrestle with the United Nations, the ability of Anna and the guardians to control the super equipment produced by those human countries is inferior to that of humans turning the light switch and pressing a button. Much simpler.

This kind of thing doesn't even need to be tacitly told.

Anna and the Guardian directly told the countries that were producing super armor with all their strength about the back door on the super equipment.

Anyway, the guardian's dimensionality reduction attack is so aboveboard for human beings.Such a small matter is not worth Anna and those guardians to lie to ordinary people.

You must know that more than a thousand years ago, these guardians were genuine god-like creatures on the earth.Although I have been educated by the three new gods now, the life level of these guys is there...

If the human nations on Earth really want to have an equal dialogue, then they really have to develop themselves to the level of star system civilization.

This kind of relationship is actually the same when it comes to Kobayashi and the others.

Kobayashi and Georgie want to really live long-term with Thor and now Jaecheon...

Then their life will undergo a qualitative change and become an advanced practitioner at the level of a guardian.

Either it is the leap of human civilization, which directly overcomes the transfer of consciousness and the cloning technology without sequelae.

Otherwise, the life levels of the two parties are too different, and the only way to wait for them in the end is life and death.

The end of science is myth.

In other words, only when science develops to a high enough level can it keep pace with mythological figures like Anna and the others.

Squinting her eyes all day long, as if she doesn't care much about anything, Elder Sister Elkoya, why is she so indifferent to Thor and Kobayashi...

It's not because the Feathered Serpent, who plays with the world all day long, has already experienced the process of saying goodbye to a special person in his life for a young dragon like Thor.

These tens of thousands of years have passed, once every few hundred years, and once every thousand years...

Over the years, Erkoya has met "Little Lin" among her dragon students dozens of times.
