The last human in the universe

Chapter 39 The Train
Compared with fusion generators, the principle of thermal power plants is simpler. It is nothing more than heating water through the mixed combustion of thorine and oxygen, and driving the generator impeller to rotate through high-pressure steam.Even, because of the lower gravity on Sedna, the rotation of the impeller is easier, and under the same conditions, the efficiency is higher than that on Earth.

After learning that a huge oxygen deposit was discovered and that there was no obstacle to building a thermal power station, the haze that had been hanging over people's heads was instantly swept away.People majoring in electric power engineering such as Chai Cheng designed the drawings of the No. [-] thermal power station as quickly as possible, and then immediately put into the construction in full swing.

The No. [-] thermal power station is located not far from the living circle, and the total area is about one million square meters, but the first phase of the project only covers an area of ​​about [-] square meters.

In the first phase of the project, it is planned to build two generators with an installed capacity of 3000KW. If the losses are removed and the generators are running at full power, the two generators can generate about 13 kWh a day.Correspondingly, it needs to consume about 70 tons of torin and 150 tons of oxygen every day.A total of 6600 tons of Thorin and oxygen are needed in one month.

With such a huge material consumption, it is obvious that there must be a special railway line connected to the thermal power plant.So some modifications were made to the road network, not only connecting the thermal power plant, but also connecting the oxygen mine, and also connecting the canyon near the living circle with a huge reserve of torin.

The daily power generation of 13 kWh can only support the operation of the railway line in the early stage, but it is far from enough in the long run.In fact, the overall planning of the No. 100 thermal power plant will have an installed capacity of 2200 million kilowatts, which can generate 110 million kilowatt-hours of electricity every day—about less than one-tenth of a famous hydropower station in the earth era. A total of [-] million tons of torin and oxygen will be consumed in a month.

By that time, the excess electricity will be able to support Zhao Changxing to build more planting workshops to produce more grain, build more animal husbandry and aquaculture workshops to produce more meat, eggs, milk and fish, and build more living quarters for more people to live in , By the way, the scale of the industrial zone will continue to expand.

In the midst of people's busy schedule, the supporting facilities of the No. [-] power plant were built first.A railway directly leads here, and thick cables are also drawn from the thermal power plant, leading to the railway line, leading to living areas, industrial areas and other places.

Various machines from the industrial area began to be installed and debugged on the initial framework, and the tolin mine and oxygen mine needed for the first month have also been in place.They were just randomly thrown in the open space, and there was no need to worry about them melting anyway.

When all the machines were debugged and power generation could be officially started, project leaders including Zhao Changxing and Chai Cheng all came to the site.

The oxygen ore and Tuolin ore were transported to the gasification chamber along two different paths, where they first heated up and melted into gas.Because they are only in the gas state, they are easy to purify and remove impurities.

This first power generation process, the electricity that melts solid oxygen and Thorin comes from outside.But after the official start of power generation, there is no need to be so troublesome.Waste heat from power plants is channeled to melt them.Now, the power plant doesn't even generate any electricity, let alone waste heat.

After tholin is purified, it becomes a mixture of gases such as methane and ethane.After the solid oxygen is purified, it becomes oxygen.The two were sent into the combustion chamber together, and the automatic ignition device ignited them. The water that had been frozen into solid ice immediately began to melt and boil, and began to produce high-temperature and high-pressure steam, which drove the rotation of the generator impeller. .

In the process of cutting the lines of magnetic force, electric energy is finally produced.On the tall light pole, the high-brightness lights flickered a few times before finally releasing a bright light, illuminating the first-phase project of the thermal power plant as if it were daytime.

The lamps installed in the factory also lit up together.

Zhao Changxing, Chai Cheng and others cheered together.

"Finally no worries, you can develop as much as you want..."

Zhao Changxing sighed in satisfaction.

At this stage, the power generation load of No. [-] Thermal Power Plant is still at an extremely low level, basically only used to maintain its own operation, lighting, and surveillance.Because at the moment there are not enough electrical appliances to consume the electricity it produces.But soon there will be an endless demand for electricity like ocean waves rushing towards it.

The laying of the railway tracks has not been fully completed, but the first and most important line - the railway track connecting the No. [-] power plant and the oxygen mine has almost been laid.The first electric locomotive has also rolled off the production line from the industrial area, and the first transportation will start soon.

The trains on Sedna have roughly the same appearance as the trains in the Earth era, only wider and with a larger load capacity.Because the gravity is too low here, more goods can be transported with the same power.Its one car body is 5 meters wide, 4 meters deep, and 40 meters long. One car can transport almost 800 tons of water ore, or 600 tons of oxygen ore.

Its nose isn't even aerodynamic at all.The reason is simple, there is no air on Sedna.

It is unmanned, and Xiaoxi controls the whole process of running on the rails.

Its first passengers were some construction machinery, some building materials, and some construction personnel from the industrial zone.They will take this train and spend more than three hours to reach the No. 130 oxygen mine about [-] kilometers away, and use these building materials to build a mining base there.After that, these dozen or so people will be stationed there for a long time, and will be responsible for the mining of oxygen mines for a long time.

Feeling the shaking of the ground and listening to the non-existent train whistle, Zhao Changxing looked at the first train on Sedna and waved to it.The next moment, the electric energy from the thermal power plant drove it into the boundless darkness.

The construction of the power plant has been going on, the construction of the train is also going on, and the rails are being laid. The stations appear one by one on the desolate land of Sedna Star. The various facilities and personnel are slowly in place. In front of Zhao Changxing, finally appeared Dozens of trains full of goods are busy running.

Iron ore from Huangtie No. [-], manganese ore from Manganese No. [-] mine, solid oxygen from Oxygen No. [-] mine, Tuolin mine from Tuolin No. [-], solid ice from Water Mine No. [-]...

Endless materials began to gather in the industrial area, and turned into pieces of steel plates, machines, parts, etc., leaving the industrial area, or flowing to the construction site, or to the industrial area...

At this moment, the population of human civilization has officially broken through the [-] mark, and the adult population has exceeded [-].In the industrial zone, almost all primary industrial products can be produced. Some high-end industrial products, such as chips, have been formally produced in the laboratory and are currently undergoing mass production research.

The computing power of this first-generation chip is far inferior to those brought from the earth, and basically has no practical value.But it doesn't matter, after completing the breakthrough from 0 to 1, it is much easier to complete the breakthrough from 1 to 100.Besides, the requirements for industrial control chips are actually not high—for example, the chips installed in a tractor, what do you need such high performance for?
Soon, people on Sedna will be able to use the chips they produced.

But this was not what pleased Zhao Changxing the most.What made him most happy was that the people on Sedna finally had the first drug production line now that the medicine reserves brought from the earth were almost exhausted.

This first pharmaceutical production line can produce nitroglycerin tablets, which can treat angina pectoris.With the ability to produce by themselves, elderly people with heart disease no longer have to worry about running out of medicine.

Various antibiotic production lines, medical consumables, and medical equipment production lines are also under preparation.Soon, almost all common diseases can be solved by self-produced drugs and devices.High-tech medicines brought from Earth could be stored until emergencies.

Besides, another thing also made Zhao Changxing very happy.That is, the first set of spacesuits produced by people themselves has finally successfully rolled off the assembly line.

There were only 400 space suits brought from the earth at the beginning, but now the number of adults has exceeded 2000, which is obviously not enough.At this stage, people are adopting the method of building life-support facilities in factories and bases as much as possible, so that people can work without leaving the life-support environment, which greatly reduces the frequency of use of spacesuits.

However, the scarcity of spacesuits has always been a constraint for people, making people have to give up many construction needs that can be quickly resolved through extravehicular operations.For example, because of the lack of spacesuits, the task of laying the rails was delayed a lot.

Now, I have the ability to produce spacesuits. Although the various indicators of this spacesuit are much lower than the spacesuits brought from the earth, it is still usable, and this bottleneck is easily solved.

Now that all developments are on the right track and there is no overall bottleneck in a short period of time, Zhao Changxing began to think about another problem.

With the rapid increase of population, Zhao Changxing felt more and more clearly that the efficiency of the whole society had been greatly reduced.

Problems such as unclear rights and responsibilities, uneven distribution, and personnel confusion have become more and more prominent.

"It's time to establish a government that will fully coordinate all aspects of civilization."

Zhao Changxing made up his mind.
