Chapter 235 The Farm
After issuing various orders.

Seka and Fan Yunfeng, the logistics team leader of this secret base, went among them to check the storage and production situation of the base.

The construction of this base has been going on all the time, and after nearly two years of expansion, it has become fully equipped and extends in all directions.

In this base, there are two places in the core area.

At this moment, Seka and Fan Yunfeng were inspecting one of the core areas.

This is a single-floor area of ​​5000 square meters, divided into 4 floors, in which a large number of cultivation pools are arranged, the genetic recombination medium in the cultivation pools, and the biological material culture medium secretly transported from Hongshawadi.

The lowest layer is the nutrient absorption pool, which can use animal excrement and plants as nutrients, and then supply nutrients and energy to the cultivation pools on the upper layers.

As for other metal powders, inorganic salts, etc., they can also be collected nearby by bio-accumulating lichens and mushrooms.

At present, this material and parts cultivation area can produce most of alloys, non-metallic materials, biological materials, and parts with less complex structures under the condition of sufficient raw materials.

The production capacity is about 1200-1500 tons per month.

For example, firearms, small hardware, glass products, generators, pure mechanical equipment, crystal sponges, and rubber products in the base can all be produced here.

It is precisely because of this highly self-sufficient mode that Tianzhu did not realize that there would be such a powerful force hidden in this remote mountain village.

After all, it is the biggest advantage that there is no need to import a large number of equipment and equipment from the outside world.

Even inside the base, Hongshawadi supplies a small amount of precision parts and biocomputers to build a mini chemical factory that can produce more than 200 tons of TNT or some other chemicals every month.

Seka and Fan Yunfeng inspected the parts production area and the chemical production area, and then went to another core area.

Another core area is a "farm" built deep underground in a mountain.

As a highly self-sustaining base, the food supply must be self-sufficient.

Although new humans can install an external auxiliary digestive sac, and then directly feed the auxiliary digestive sac grass, trees, poisonous insects, carrion, cow dung, etc., and then obtain energy and nutrients from them, so as to maintain the normal life needs of the human body.

Even in more extreme environments, "plant exogenous armor" and "hibernation life capsule" can also be used.

Plant exogenous armor is actually a variant of exoskeleton armor. Its function is more focused on wilderness survival and doomsday survival. It can directly carry out photosynthesis and absorb nutrients in soil, air and water through genetically recombined plant cells on the surface. Thereby maintaining the life of the user.

The hibernation sac is used in special environments, such as deserts, polar ice sheets, and areas heavily polluted by chemicals, and it is difficult for the body to escape from these places. Let this sac wrap the body and enter a kind of Feign death hibernation state.

At present, the hibernation life support capsule can maintain a dormant period of about 120 days at most. Some new humans who perform special tasks need to use this kind of thing.

The base where Seka is located is equipped with auxiliary digestive sacs, plant exogenous armor, and hibernation sacs.

However, these devices are used only in extreme cases.

Some normal food is still very necessary when we are not at the end of the mountain.

So the "farm" came into being.

Due to the underground environment, natural light is basically not considered, and artificial light requires a lot of energy, and the energy efficiency of photosynthesis of plants is actually not high.

Genetically modified organisms like luminescent lichens are not suitable as light sources for underground farms.

After many studies and experiments, Li Qingye finally found a technology that allows plants to grow rapidly without sunlight, and increases the rate of organic matter production in plants by more than ten times.

The specific principle is to use a composite electrocatalytic system to convert carbon dioxide and water into acetate, and then the plant body can directly absorb acetate, thereby bypassing the stage of photosynthesis.

At present, this technology has been successfully applied to some genetically recombined plants.

And this technology is at the heart of the underground farm.

In this way, a large number of planting rooms have been built in the farms in the base, which can produce cucumbers, tomatoes, soybeans, sweet potatoes, potatoes, corn, eggplants, pumpkins, wax gourds, peppers, green peppers, strawberries, watermelons, and sugar cane.

Seka picked off a small cucumber, wiped it casually, and gnawed it: "Can the production of the farm now completely replace the farmland on the surface?"

"If we only maintain the current population, there is no problem." Fan Yunfeng replied.

Seka frowned. The current population of the base is 793 people.

But this is only for now, as the plan unfolds, the population of this base will definitely skyrocket.

He continued: "How many people can the maximum capacity supply?"

"3000 people is basically the sustainable limit."

"Is there a way to expand it?"

Fan Yunfeng thought for a while: "In fact, we don't lack underground space. After all, we can arrange several more floors. The key issue now is the power supply."

"Electricity..." Serka also felt very troubled when he heard this question.

The power currently used by the base is actually more than a dozen small gas turbine generator sets with a total power of 1400 kilowatts.

Its fuel source is the methane fermenter, on the one hand, it relies on human and animal excrement, and on the other hand, it is usually collected plant raw materials, such as straw and dead branches and rotten leaves.

The generating power of 1400 kilowatts is already the limit of this base.

Even with gas turbines and power plants, there isn't enough biomass to produce methane.

After thinking for a while, Seka asked, "Can underground shale oil and shale gas be developed?"

"Hehe... It's a pity that there aren't many oil-bearing shales in the rock formations near Shillong." Fan Yunfeng spread his hands.

The energy problem at the Shillong base made Seka scratch his head.

Now there is only a population of more than 700, so naturally there is no big problem. Once the population increases, the demand for energy will definitely skyrocket.

The problem is that according to the estimation of the headquarters, the Tianzhu people will not let go of the Assam states, and this place will definitely become a flesh and blood mill.

Thermal power plants, solar farms, wind farms, hydropower stations and the like that are too obvious on the ground will definitely become targets.

Even if it is made, it is still a target.

Therefore, we must find a way to solve the energy problem of the base. Only by solving the energy problem can the upper limit of population capacity here be increased.

Although Seka considers himself a new human beyond race.

But ordinary people are innocent after all, if he can save more ordinary people, he is still willing to try.

Suddenly, he had a flash of inspiration, turned on the tablet he was carrying, and called up the three-dimensional topographic map of the surrounding area, and soon he found what he wanted.

"Old Fan, do you think this works?" He pointed to a nearby river valley with a drop of more than 80 meters: "We can use artificial mud-rock flow technology to artificially block this river valley and form a barrier lake."

"Barrier lake?" Fan Yunfeng looked at the three-dimensional topographical map: "You plan to build a hydropower station? But this is too obvious."

"No! We can use rapid excavation technology to create an artificial underground river, and then install the hydropower station in the mountain." Seka said while drawing a hidden path in the mountain between the two drops. Underground dark river.

Fan Yunfeng recalculated and found that this plan is indeed feasible. Based on the flow of this river, it can probably drive a water turbine with an installed capacity of 10-20 megawatts.

This power generation is almost 10 times that of the base.
