Homo sapiens.

This cost does not pose much pressure on Homo sapiens.

Li Qingye flipped through the latter part of the plan, and found that the engineering department had further plans.

That is, based on the high-altitude railway, gradually increase the scale of the vacuum airship until the airship goes directly to the Karman Line and reaches an altitude of 100 kilometers.

According to the principle of the vacuum airship, its maximum flight altitude is about 85 kilometers, and the vacuum buoyancy of the airship is not enough.

The engineers of the engineering department plan to adopt the arch bridge scheme to extend the structure upwards.

This is also the reason why they build on the equator, because the angular velocity of the equator is parallel to the equator.

The equatorial railway can also adopt an arch bridge structure to enhance the structural strength and its own supporting force to ensure the Karman line that can extend the entire structure.

As long as the equatorial railway is extended to the Karman Line, astronauts can take the elevator directly from the ground to the Karman Line, and then take a spacecraft to outer space at the space port of the Karman Line.

Using this method to go to outer space is safer than taking a launch vehicle, and the comfort is also very high.

Similarly, materials entering and exiting the atmosphere can also be very convenient, without considering issues such as atmospheric resistance and friction, let alone worrying about the pull of gravity, causing the spacecraft to lose control.

This idea is very good, but Li Qingye did not blindly approve of the later ideas.

"Material strength and weight, can it reach this level?"

Liu Zhifan shook his head: "There is no problem with the stratospheric railway, but the materials for the Karman Line platform are not yet available. Materials that meet the strength standards are too heavy; materials that are ultra-light in weight do not meet the standards for strength."

"Is that so?" Li Qingye pondered for a moment.

Although there are no suitable materials at this stage, he still approves of the first stage of the stratospheric railway: "In this case, let's build the stratospheric railway first! For the later upgrade and transformation, we will consider whether to build it after the materials meet the standards. "

"Yes." Liu Zhifan replied excitedly.

Chapter 500 Slag Crusher

After discussing the equatorial stratospheric railway.

Liu Zhifan reported another incident.

"The gold mining city in Antarctica has now increased its gold production capacity to 230 tons per month."

Li Qingye's eyes were calm: "230 tons? Not bad, barely enough, and can accelerate the industrial coverage of gold-based thermoelectric materials."

"I have asked various industries to submit application applications for gold-based thermoelectric materials, and they are currently being screened. Personally, I am more inclined to apply them in the production process." Liu Zhifan replied.

Li Qingye agreed with his thoughts: "The production link? Well, we should really focus on the production link, and the consumption link can be postponed."

After the two-layer thermoelectric conversion of gold-based thermoelectric materials, the thermal efficiency can reach about 97%, which is already very high.

Considering that there are relatively few parts using thermoelectric materials in electronic products and household appliances, and the cost of gold-based thermoelectric materials is relatively high, the cost performance is not high at this stage.

It is different when it is directly applied to the production link.

For example, in a nuclear power plant, after using gold-based thermoelectric materials, the power generation can be doubled.

Another example is a food processing plant, where many links require high-temperature heating or low-temperature maintenance in a large area. If gold-based thermoelectric materials are used, waste heat can be efficiently recovered and efficient cooling can be achieved at the same time, which can save a lot of energy.

Although Homo sapiens has a large number of nuclear power plants, nuclear reactors and nuclear batteries, and other energy sources are also very abundant, it does not mean that they can squander energy recklessly.

Improving thermal efficiency is conducive to reducing production costs and can also increase the overall energy supply scale.

If all the nuclear power plants of Homo sapiens were replaced with gold-based thermoelectric materials, the scale of these nuclear power plants would not change, but the power generation would double.

Technology is at the heart of productivity.

Even if Homo sapiens does not add new power stations, it can still increase the total power generation by about 82% just by transforming old power stations.

If there is no gold-based thermoelectric material, in order to increase the power generation capacity by 82%, Homo Sapiens will have to increase the total size of the current power generation equipment by 82% to achieve this goal.

After reporting on gold mining and the promotion of gold-based thermoelectric materials, Liu Zhifan went on to say:

"Chairman, recently, many forces have secretly contacted us, hoping to sell some land to the company in exchange for some life-extending drugs and life-extending symbionts."

"Oh?" Li Qingye sneered: "The wishful thinking is really cracking."

Carmen Lopez speculated: "It is estimated that because we recently purchased those small islands, they thought we would covet those lands, so they tried our bottom line."

Li Qingye would not sell life-extending medicines and life-extending symbionts to those Tianlong people just because of that little land: "Just reject it and let them die."

"I understand." Liu Zhifan nodded.

At the same time, Li Qingye secretly wrote down this matter in his heart, and planned to ask Chen Jianxiong and Bagheira to strengthen the screening of migrant workers.

In fact, Homo sapiens has always had a very clear rule for migrant workers or locally recruited employees, that is, no one with a serious criminal record.

Petty theft and the like have the opportunity to become employees of Homo sapiens company, and Homo sapiens company will not recruit those who are full of crimes, and will even do it directly, sending them to the crash course of Aoba University for further study.

After all, Qingye University was originally in Hongshawadi, but recruited 10,000+ scumbags, and then turned them into "loyal" and "versatile" soldiers.

The crash course sent to Aoba University is a slang word inside the Sapiens company, but it is actually sent to become a soldier.

Homo sapiens still maintains the crash course of Aoba University.

Regardless of Homo sapiens company's willingness to come, in fact, there is an invisible threshold, coupled with pervasive intelligence gathering capabilities, if you want to hide everything in the past, mixing with Homo sapiens company is basically a dead end.

Especially for those scum full of evil, entering the gate of Homo sapiens company is basically two choices: soldiers or fertilizers.

In the past, many scumbags tried to mix into Homo sapiens company, and then they worked in Homo sapiens company for less than a period of time, and they often received box lunches due to "accidents".

At the beginning, many people didn't know the tricks.

Until there were too many missing or dead people, and it was too "coincidence", those similar scumbags who knew about these scumbags and had not come to Homo sapiens company also began to notice something was wrong.

After all, the relationship networks of many scumbags are intricate. After some investigations, such as making phone calls, sending videos, emails, etc., they have not been able to contact those scumbags who have mixed into Homo sapiens, and they know what happened. seriousness.

If one or two accidents happen, it can be described as an accident.

But now there are hundreds of scum, disappearing inside Homo sapiens company, which is really terrible.

It was Li Qingye's personal order to clean up these scum.

On the one hand, he doesn't like these scumbags. If these scumbags are allowed to enjoy the high benefits of Homo sapiens company, wouldn't Homo sapiens company become a garbage dump and a scumbag shelter?

On the other hand, it is to purify human genes.

The development of human history has always been bad money chasing good money, which makes it easier for bad people to survive and pass on their genes.

Therefore, when the Homo sapiens company recruits employees, it will secretly conduct a secret screening, and remove the scum full of evil from the concept of "Homo sapiens", completely ending the continuation of its genes.

In this way, purity within the company of Homo sapiens is ensured.

After those scumbags learned about this situation, they seldom dared to come to Homo sapiens company to apply for jobs.

Only some wild scum, because they don't know this unspoken rule, will come to apply for the job foolishly, and then they will be secretly disposed of by Homo Sapiens.

Li Qingye is indeed very ruthless in this regard, which may have something to do with his personal experience, and seems a bit jealous.

He is also very contemptuous and hostile to the Celestial Dragons who secretly tested the bottom line of Homo sapiens this time and tried to obtain life-extending drugs and life-extending symbionts.

From the very beginning, Li Qingye hated some people very much, and it was doomed that he would not be able to accept those scumbags.

Liu Zhifan and Carmen Lopez are naturally very aware of the experience of the boss.

Especially Carmen, who came from a big family, he is very clear about the fate of those scumbag members among the five big families in Luzon.

Liu Zhifan said cautiously: "Mr. Chairman, there is another matter, mainly about the medical business department."

Hearing this, Li Qingye already guessed something: "Is it about the human genetic recombination experiment?"

"Yes, the executives have different views on this experiment." Liu Zhifan replied very cautiously.

Li Qingye waved his hand: "Don't worry! In a short time, we will not conduct human experiments, at most we will conduct humanoid experiments."

"Is that so? I understand." Liu Zhifan secretly breathed a sigh of relief.

In fact, he is opposed to large-scale human gene recombination experiments. After all, this scientific research project is too dangerous, and if it is not done well, it will cause chaos and division within human beings.

The technology at this stage is not yet mature, and there are still some unpredictable situations. He doesn't want to see any aliens, mutants and the like emerge.

Chapter 5 and One: The Rebirth of the Rainforest

Amazon rainforest area.

As the largest tropical rainforest on earth, the cities and people here are very difficult.

On the one hand, due to the high temperature and rain all year round, the construction of infrastructure is very difficult, and the maintenance is even more troublesome.

On the other hand, the land here is very barren, otherwise the arable land of the Redwood Federation would not be concentrated on the Redwood Plateau.

The Marquez family once lived in a small town in the Amazon rainforest.

Before the year before last, he thought that life was just like that, and he had been dawdling in the small town.

until one day.

A force called Homo sapiens entered the Amazon rainforest, and the Marquez family became temporary employees of Homo sapiens in a daze.

At this time, he was building an overhead railway.

A huge construction airship is parked on the hollow pipe that has been pierced deep into the ground, and the airship is temporarily docked on the column.

Marquez is wearing a working exoskeleton and is working with the construction airship to assemble various modules.

Suddenly, a sound came from inside his helmet.

[Please leave work immediately and return to the airship, the rainstorm will arrive in 20 minutes...]

Marquez turned his head and glanced to the southeast. A large black cumulonimbus cloud was rolling in.

He didn't rush, he tidied up the work area in an orderly manner, and then was taken to the location of the temporary elevator, and took the elevator up to the rest cabin of the construction airship.

Captain Li Xiong counted the number of people, and then picked up the walkie-talkie: "Everyone is here, let's take off!"

The pilot in the cockpit replied immediately: "Got it."

The construction airship released the temporary buckle between the column and the column, and then quickly pumped up the vacuum and climbed to a high altitude.

Although the wind and thunderstorm resistance of large airships are quite good, it is really unnecessary to carry out construction against the storm.

In case of being struck by lightning, even with an exoskeleton and a giraffe, the body may not be able to hold it.

"Tropical rainforest is troublesome, it rains every day." Marquez complained.

Li Xiong opened the refrigerator in the cabin: "What do you want to drink? Take it yourself."

After taking off the exoskeleton, Marquez took a bottle of sugar cane juice.

Another local employee leaned against the window: "Head, didn't the company decide to set up a protected area in the Amazon rainforest? Why do we need to build an overhead railway?"

After drinking more than half of the sour plum juice, Li Xiong burped: "Hi... not all of them are nature reserves. Those areas that have been developed need to be readjusted and planned."

"What the hell is there to build in this place?" Marquez has lived in the Amazon rainforest for more than 20 years, and he doesn't like it at all.

Li Xiong also understands the feelings of the locals like Marquez. After all, the living environment in the Amazon rainforest is indeed too harsh. Even if Homo sapiens has various technologies, it still encounters a lot of trouble here.

The new cities Homo sapiens invested in here all adopted special designs.

It is to use part of the technology of building overhead railways, directly use hollow pipes as foundation columns, and build cities similar to stilt houses.

There is often a gap of about 50 meters between the entire city and the ground.

The former Amazon towns were largely abandoned. After all, the infrastructure of those old towns was so poor that they were often flooded.

The locals didn't care too much, and most of them happily went to settle in the new city.

About 47 kilometers northwest of the construction airship, there is a new city - Nepenthes City.

A very distinctive name, which is also commonly used in the naming of new cities in the Amazon rainforest, that is, to use local common or unique animals and plants as the name of the city.

After all, there were too many repetitions of the previous city names.

Nepenthes City is a small city with a population of 32.

Marquez, who worked on the construction of the airship, and his family lived in this city.

Marquez's sister Julia, as an ecological investigator in the area, is currently driving a hovercraft with several colleagues to observe the vegetation restoration on the nearby river.

A colleague frowned: "The recovery speed of the forest here has not met expectations!"

Julia put down the binoculars: "It may be related to the pollution from the previous lead-zinc mining here."

"This kind of ecological restoration work is too difficult."

"Go back! In an hour, the cumulonimbus will reach us."

"All right!"
