Superman, the Man of Steel, female, 6 years old!

Moreover, even in the living space, all decoration grades and material costs, except for differences in color and style, all costs and resources used need to be controlled at a strict and similar level.

This mandatory modularization of living space does not only exist in space cities and "biological battleships".

Except for the Earth Reservation.

It will be prevalent in all future human outer space colonies, such as lunar bases, Mars bases, and outer space meteorite mining stations.

That is to say, the future human beings on Earth.

At least until the end of the war, above this human habitation space...

It is to achieve the unity of world peace and harmony.

Save manufacturing costs.

Therefore, all the current honeycomb-like hexagonal barrel modules are all produced using a one-piece molding model of all metal, or almost all stainless steel metal.

After Anna obtained the qualification certificate for her car recycling plant, the younger brothers in the company began to collect scrapped cars. The manufacturing cost of these mass-produced residential modules was shockingly low.

Because the living module hardly uses the robotic arms and conveyor belts in the agricultural module, nor does it use the water pump equipment in the smart farm, as well as various sensors, LED lights, etc.

The raw materials for the stainless steel metal used in the manufacturing process were almost all free, and Anna and the others were even paid for it...

Therefore, when Anna and her colleagues were building this entire "floor" of living space, the actual cost they spent was actually the price of the chromium, nickel, molybdenum and other mineral powders that were added to the scrap metal when it was smelted into stainless steel.

The new floor that grew out of the magic building is about the size of three football fields, which is a square with a side length of about 180 meters, and the entire space has a clear height of 100 meters.

In other words, if not even a single gap is left, then this space can accommodate more than 537819336 residential modules.

But when actually operating, of course you can't stuff it in like this.

Anna and her team also need to leave aisles, build the main frame to place the modules, and build a freshwater purification center, air-conditioning and ventilation center, various wires and pipes, a biomass degradation system and other things at the bottom.

The most important thing is that every floor of the living space must be equipped with a kindergarten, primary school, medical room, gym, shop module, centralized canteen module, and most importantly, an open park, etc.

So in reality, this living floor, which is specially designed to test life in future space cities, has no space left for anything else after 7000 living modules are placed there.

That is to say, if energy consumption and food supply are not taken into consideration, each of these residential floors can accommodate more than 10,000 people.

The more than two million US dollars that Anna spent on this floor was actually the cost of ore materials when smelting stainless steel, as well as the cost of purchasing equipment for the fresh water purification and air-conditioning ventilation centers.

To save costs, Anna even cut the sheathing of the wires and other rubber parts inside the living module...

They are all made from rubber tires removed from old cars and the waste oil left in those cars as raw materials.

It saves money to the extreme.

If you really need to run away in 20 years, these standard living spaces will be a cheap and efficient option.

If food production is not taken into consideration and each floor is built into such a living space, then each vine warship with 1000 "floors" will be able to provide relatively comfortable living space for more than 1000 million people.

And if they save money like Anna does, let the guardians do the construction, and the metal raw materials are also free like Anna, then they only need $200 billion to transform it into a "Noah's Ark" that is completely for living and can accommodate more than 1000 million people for daily residence.

By then, only more than 700 vine biological warships will be needed to completely solve the long-distance transportation, emergency evacuation, and daily living needs of the 70 billion people on Earth in the future.

Of course.

This is without considering the enormous energy consumption when so many people live together.

This is only possible without considering the production and consumption of food.

Therefore, the super-large space cities, space farms, underground bases on the moon, underground bases on Mars, ice and mining bases in the asteroid belt, and other facilities for production and living that are being planned in the future are still necessary and indispensable.

Moreover, these things are not just prepared for escaping after the war is lost.

Even if the opposing gods, churches, and kingdom soldiers cannot defeat us, even if we win the plane war.

These things are also the basic reserves and space assets for Earth civilization to truly move towards the solar system in the future and become advanced civilizations in the star system.

This does not conflict with the fact that the world's superpowers are currently conducting research and production to prepare for war and famine in 20 years' time.

Chapter 266 Solving the Agricultural Module Problem

After solving the future housing problems, energy problems, and biological warship problems, we must solve the problem of future food production outside the earth.

This is exactly the job of the one hundred or so researchers who came to Tokyo from Aomori Prefecture to conduct isolation experiments.

Because the vine-version biological battleship is a semi-enclosed space, the problem of food production is divided into simple production methods within the floor space and highly difficult production methods that are completely sealed in alien colonies in outer space.

After so many years of closed biosphere experiments, the scientists on Earth are no longer fake.

Therefore, for them, producing food in the floor space of the vine-shaped biological battleship is just a simple matter of sprinkling water.

The two fully enclosed and simple control group agricultural modules that Anna had built in the space on the first floor were just outdated technologies from several years ago for these researchers.

The projects they have been researching and focusing on in recent years, to put it in a high-level way, are to rebuild the entire Earth's biosphere in the future, and to use these technologies in future planetary transformation projects and giant space cities.

This is much more impressive than Anna's low-level project from the beginning, which was just to grow vegetables in the magic building.

So after acquiring these one hundred scientists and researchers, the original fully sealed one was fine. However, the simplified farm module that Anna had first created was instantly outdated before the first batch of vegetables were even grown.

This is because the module is not sealed enough for use in outer space, and for planting on Earth, or in a semi-enclosed space like the Magic Building, the excessive number of robotic arms, conveyor belts, water pumps, and other things in this farm module seem too expensive.

Although these things are just scrap metal for Anna, if other people or organizations want to mass-produce this simplified farm module in the future... such a cost is still not feasible.

So after just over ten minutes of wandering around Anna's original ground floor, the scientists among the researchers provided Anna with two different solutions of simple agricultural modules.

Because of sufficient research funding, automated farms and vertical farms are no longer rare technologies in the world.

The only difference between them and traditional farms is whether the cost is appropriate and whether they are necessary.

So the two options the scientists gave Anna were both very mature commercial technologies, but Anna hadn't used them before. The first reason was...

She could build her own simplified version of the outdated farm using scrap steel.

The second one is that it contains many patents of other listed companies...

She didn't have much money at the time to buy the full set of technology from those listed companies. Besides, they would definitely sell it to others...

However, after the introduction of the global "exclusive sharing law", these previous problems have become much easier to solve.

With Anna's current points and research funds, she can also freely choose patented technologies that have entered the public domain.

And the automated farm technologies that she couldn't afford and couldn't buy before, at this time... and because those countries needed to earn points, these unimportant things entered the global public patent field.

Scientists now offer Anna two farm technologies to choose from, one that makes full use of sunlight, and the other that uses no sunlight at all.

Moreover, both technologies are mature technologies of many listed companies in the world today.

The first vertical farming technology that fully utilizes sunlight originated from Sky Greens in Singapore, which developed a planting technology called "A-Go-Gro".

This technology uses hydraulic and gravity principles to develop multi-layered troughs within a rotating A-frame vertical structure that stands up to nine meters tall and features 38 layers of growing troughs that can accommodate different soil or hydroponic growing media.

The growing troughs automatically rotate around the A-shaped frame, changing position at a speed of 1 mm per second, ensuring that crops receive even sunlight, irrigation and nutrients as they pass through different points in the structure.

Compared with traditional single-layer farms, Sky Greens' vertical farming system can increase land utilization and increase yield per unit land area by at least 10 times.

And most importantly, it uses natural light completely, without artificial lighting, which is very suitable for Anna, who has the power of the sun god.

Because she can hang one or several free small sun-like light sources on each floor used for agricultural production.

As for the energy consumption of this little sun and how to maintain its luminescence, all we have to do is connect it to the vine network in the magic building and the quantum energy supply chain.

Not even the Ark reactor's power generation is needed.

The rotating frame uses a unique hydraulic water drive system that harnesses the energy of flowing water and gravity to rotate the growing troughs, powering the farming system.

Only 0.5 liters of water are needed to rotate the 1.7-ton vertical structure, and the water is stored in a closed underground reservoir. The water can be pumped to a higher place and then recycled for reuse.

The power consumption of each rotating tower...

That's equivalent to a 60-watt light bulb.

Yes, you are not mistaken.

The power consumption of this vertical farm is only equivalent to that of a 60-watt light bulb.

Moreover, its construction cost and maintenance cost are the lowest. Not to mention people like Anna who can get metal for free and even get paid by the Japanese government, even other companies have the lowest cost to build such a farm.

After all, it is just a 9-meter-high A-frame, some planting troughs, and things like chains and water pumps. It does not require much high-tech and additional sensors and electricity to consume the cost of planting.

This pattern is very suitable for planting in Anna's current floor space.

Well, apart from the fact that there is no automated system for sowing and picking, so a lot of manpower is needed during harvesting, and the output is only ten times that of traditional farms, this solution has almost no disadvantages.

Although this is a bit inconvenient for Anna and the others, after all, she doesn't want a large number of hired workers coming in and out of her farm every day.

However, for the future refugees who will have no shortage of manpower, whether it is on the floors of the biological warships or in the future underground bases, as long as the problem of free light sources is solved...

Even if they do not build the Ark reactor for controlled nuclear fusion, they can still grow sufficient food using this seemingly less high-tech technology.

Chapter 267 The Second Set of Future Agricultural Plans

The second agricultural plan provided by scientists to Anna.

It is a vertical farm solution that is built entirely with high technology and integrates the technologies of several commercial companies. It has the highest energy consumption but also the highest output.

This is different from the previous vertical farm solution from Singapore, which is low-carbon and low-cost.

The latter option can achieve an average per-acre yield of 390 times that of traditional farms.

However, in terms of construction cost, maintenance cost, and electricity consumption, it far surpasses Singapore's low-cost solution of using natural light.

Its biggest advantage is that no soil, sunlight or rain are needed during the entire planting process. All it takes is sowing the seeds on rows of constant temperature shelves indoors, and spraying fertilizers via remote control. No pesticides or chemical fertilizers are needed.

Some American companies that use aeroponics can complete the entire process of growing vegetables, from seeds to harvesting and then to the table, in as little as 12 to 16 days.

, including temperature, humidity, light, water and plant nutrition, and you can also customize the simulated solar spectrum of LED grow lights and so on.

It tweaks the chemical makeup of plants to engineer the vegetables for their optimal nutritional profile and flavor.

This ability to customize nutrition and taste is also a major advantage of fully automated plant factories compared to traditional farms.

For example, there is a vertical farm in Japan called Espec Mic. They can grow inorganic green leaf lettuce in seawater pumped from a depth of 800 meters. After mixing it, they can cultivate lettuce that is rich in calcium, potassium, and magnesium and has fresh and delicious leaves.

In addition to being grown using seawater, this lettuce tastes even better than traditional crops of the same type.

Such high-tech farms have actually existed for several years in places like the United States, the Netherlands, Dubai, and Japan, and many commercial companies are constantly updating their technology.

In Japan alone, there are now 182 plant factories in operation.

The largest Japanese vertical farm company is Spread, which is located in a plant factory in Kameoka City near Kyoto. The entire factory consists of only two buildings covering an area of ​​900 square meters.

The total planting area has reached 2.52 square meters, and 2.1 heads of lettuce can be harvested every day.

That is to say, for every 1 square meter of area, this plant factory can produce 304 lettuces every year.

After using more advanced automatic technology, the output of Spread's Techno Farm in Tokyo doubled, with the lettuce yield reaching 648 heads per square meter.

However, although the output of these vertical farms is hundreds of times that of traditional farms, the annual sales of these high-tech vertical farms actually only account for 0.15% of Japan's domestic vegetable market.

It saves labor costs and reduces losses during transportation.

But these costs are not the big part of this automated farm.

Their biggest disadvantage, apart from the huge construction, equipment maintenance and depreciation costs, is that they consume too much electricity.

Therefore, before the emergence of cheap energy from controlled nuclear fusion, these high-tech plant factories, which have output hundreds of times that of traditional farms, have been unable to capture a larger market.

In addition to being able to grow only ultra-fresh vegetables with a short growing period and high added value, these high-tech agricultural companies can only survive in the business world by locating within large metropolitan areas such as Tokyo and Osaka.

For example, wheat, corn, soybeans and rice have a long growing period and are the world's main food crops. It is impossible for them to be grown in the vertical farms of their own companies.

Because after doing the calculations, light is just the lighting cost inside a vertical farm if wheat is grown indoors.

For every loaf of wheat produced, these companies' electricity costs would reach a staggering $11.

But this is for other companies.

Like after Ana's Ark Reactor came online.

Even if they only grow wheat, their electricity costs are only about one thousandth of others'.

In other words, the electricity cost for Anna and her colleagues to grow the wheat needed for a loaf of bread is only about 1 cent.

In addition to only using 1% of the water resources.

Save 40% to 50% of labor costs.
