Chapter 303 Food Issues
There is no way, although the space elevator ground base uses a server group composed of small supercomputers.

But a conventional computer, even a supercomputer, is nothing to a quantum computer. A supercomputer covering an area of ​​hundreds of square kilometers has less computing power than a quantum computer the size of a suitcase. Computers are awesome.

For example, this time the control of the sky elevator was taken back to the world, and the calculation generated by 550C was used to easily crack the supercomputer that originally controlled the space elevator.

The small size and high height are naturally very suitable for placement in places such as space stations and the moon where there is no air for heat dissipation and it is not very convenient.

After all, although ordinary supercomputing computers have powerful computing capabilities, they also require greater heat dissipation, which is different from ordinary computers that can use a cooling fan to dissipate heat.

Basically all supercomputers use liquid cooling for heat dissipation, and only liquid cooling can suppress the heat generated by supercomputers when they run at high speeds.

The most powerful supercomputer before Liu Xiu's time travel, the Border supercomputer, which could perform tens of billions of operations per second, was roughly as powerful as the 550C.

But don’t forget, in order for Border Computer to achieve such powerful computing power, the weight of the unit cabinet alone exceeds one hundred tons, and coupled with the supporting cooling equipment, its weight also exceeds one thousand tons.

But this is not the most critical thing. The most critical thing is that the battle for the control system of the space elevator base has allowed more people to see the superior performance of quantum computers.

Therefore, the technology behind the construction of planetary engines came to Liu Xiu. The quantum computer 550C can be used to fully automate the construction of planetary engines. This can avoid the flow of energy on the Blue Star before the helium flash comes. The propulsion engine has not yet been built.

For example, the welfare of workers who build planetary engines must be solved, as well as the issue of rest.

Compared with Ouzhou and Mizuo, which are always talking about this and that, Yazhou's side is much better. It's no problem to work in two shifts of not to mention eight hours, but even twelve hours.

Yes, Liu Xiu has already felt that if the current construction speed is maintained, the underground city can only accommodate half of the world's population at most, while the other half will be forced to freeze and starve outside. .

Liu Xiu looked at such hard-working Huaxia people and naturally did not want to see the planetary engine and underground city they had built so hard. In the future, they would have to draw lots evenly with Ouzhou, Mihao and the guys from the Philippines. Liu Xiu It feels unfair.

In fact, the reason why the Planetary Engine Underground City can only house the average population is mainly because of insufficient food. After all, if we just talk about simply accommodating the population, with the space of the underground city, let alone 8 billion people, it is 18 billion people. can be easily accommodated.

Especially in Ouzhu District and Mi'ao District, the construction workers there would go on strike for Liu Xiu from time to time, demanding three days off every four days, and even demanding a six-hour working day.

You must know that it is already 2044, and the planetary engines have been built for more than ten years, but only one-third of the agreed-upon 11,000 planetary engines have been built.

The reason why construction is so slow is naturally because the problems faced by manual construction are really big.

But don’t forget, if you want the population to survive in the underground city for a long time, then ecological circulation is necessary, oxygen circulation, food production cycle. If the population exceeds the upper limit of capacity, then this circulation system will collapse.

Of course, Liu Xiu has another way, which is mature digital life technology. The fact that Tu Yaya is alive and well in the virtual reality production game Oasis illustrates the feasibility of digital life.

Of course, the computing power of the Oasis server group in front of us cannot accommodate the digital lives of four billion people living in the virtual game Oasis at the same time. If you want to accommodate billions of people online at the same time, it may only be possible to use 550W to build a quantum supercomputing cluster.

Otherwise, those who are transformed into digital beings will end up with nothing but cold data cards quietly sitting in a corner gathering dust!

What's more, those who are not selected to take refuge in the dungeon may not agree to turn themselves into cold data storage cards.

Of course, nowadays, Liu Xiu dare not tell the ordinary people that the underground city's living capacity is only enough for ordinary people to live in the underground city. Once the ordinary people know, it is easy to know that it will definitely hinder or destroy the construction of the planetary engine and the underground city.

By that time, it will no longer be the sporadic small disturbances now. After all, the current reaction of the Spaceship Faction is actually just a small group of rich people who were raided and exterminated their wealth. At most, it can only be supported by a million people.

And now once this news is leaked, it is likely that more than a billion or even billions of people will riot.

Liu Xiu thought about it and began to look through the report submitted by Minori under Biological Cycle Research on how to increase food production.

The most feasible solution is to cultivate earthworms on a large scale in underground cities to provide humans with the protein nutrients they need for survival, growth and production.

After all, the food of earthworms is soil, or the organic matter in the soil, including feces and rotten grass.

But even so, the space and materials in the underground city are still not enough to feed all humans.

Just after Liu Xiu looked at the report sent by the research institute, he suddenly remembered why the technology of artificially synthesized fixing powder was not mentioned in the research institute!

You must know that in the world before Liu Xiu traveled through time, artificial powder setting technology already existed as early as 2021!

After all, being able to artificially synthesize fixed powder means that glucose can be produced, and with this thing, adding a small amount of trace elements can be used as the energy and nutrients needed for daily activities of human life.

Although artificially synthesized powder requires a lot of energy to replace the photosynthesis of plants, the most indispensable thing now is energy. After all, after the planetary engine is running, it is enough to extract a little energy from the cooling wastewater to generate electricity. It's running.

Of course, this synthetic fixing powder technology seemed very useless in Liu Xiu's era. After all, if you don't eat naturally grown food, you have to eat some fixing powder. Isn't this just asking for trouble!

But don't forget that naturally growing plants require space. According to calculations, if you eat naturally growing plants, you will need ten square meters of area to provide enough food for a person's life.

However, establishing an artificial setting powder synthesis factory can greatly reduce the area required for production, and the most important thing is that the main raw material for artificial setting powder is carbon dioxide.

This naturally reduces the carbon dioxide processing pressure of underground cities. After all, 10,000 planetary engines in the world naturally means 10,000 underground cities, allowing half of the population to live in it. This is equivalent to 10,000 underground cities trying to accommodate 40 people. Hundreds of millions of people live there, which means that each underground city has to accommodate 400,000 people on average.
