For a long time, small fights are often issued, but on the whole it is relatively stable, because there is no major war, so many plans have been completed in advance, such as the solar eclipse plan, it is assembled in space, it will break away from the high orbit of the giant planet, and fly towards the sun, it needs to run in a suitable orbit of the sun, and calculate the distance that completely covers the giant planet, and then adjust the speed, so that it has been completely covered by the sun on the position of the giant planet.

It takes a long time to perform this task, first it needs to accelerate, then it needs to make a few more revolutions around the sun, then it needs to go to that suitable distance, and finally it needs to adjust the speed until it is completely aligned, and then it is considered successful.

After calculation, it will take several years to complete, and this time is not meaningless for Tan Qiusheng, it should be that she also needs to use these years to deploy preparations for the harsh winter.

The ground of the Night Moon Continent has completely lost the trace of robots, and many of the mechanical facilities on it have been transferred to dungeons of several kilometers, each of which is extremely large and numerous, and there are many subway networks connected to each other.

There are many sources of energy in the dungeon, and the highest energy generation is not nuclear power, but geothermal power generation, geothermal power generation is the use of underground heat to heat water to generate electricity, want to mine the deep underground, the high-pressure geological environment has from the thick soil layer above, there is also from the heat contained in the ground, and the heat is the most tricky, the rock will dissolve into magma in the overheated high-pressure environment.

Magma will flow, machinery and equipment can not withstand such a harsh environment, if you want to continue to dig down, you must solve the problem of magma, because magma is fluid, and very high, some also contain a lot of silicon, which will cause magma to be very viscous, even if the steel pipe can withstand its heat, it can not be pumped away like a pump, viscous magma will block the steel pipeline, even if it is not blocked, due to the problem of viscosity, the pumping will become very inefficient, which is not cost-effective.

Even if you open a hole in other directions to translate these magma, it is not meaningful, you still need to continue to dig down, if there is a magma leak at that time, then the robots and mechanical equipment below are not heavy losses, so this method of making up the east wall and the west wall will not work.

Since none of these methods work, then formulate a new method to solve it according to local conditions, the magma can not be brought up, nor can it be translated to other areas, then the only way is to take the initiative to cool it, let it cool down, become solid, at that time there is no problem with how to excavate.

There are many ways to cool, transport water in, cool down with water, such a rough and natural simple method, it is definitely not possible, after the water hits the magma, it will evaporate, and in the underground this very closed environment, the water vapor will eventually become high-pressure superheated steam, these steam will reach more than 400 °C, and the steam under high pressure is also easy to get out of control, leaking out will cause great destructive force, robots and mechanical equipment will be burned out.

And the decomposed gas, as well as hydrogen, once combined with the right amount of oxygen, a spark will become a bomb, and the underground will be blown up, and the losses will be heavy at that time.

Even if you don't consider safety considerations, it is very inefficient to say that such rough cooling can cool the surface of the magma and make it become rock, but the bottom of the rock cannot be well contacted and cooled, which will cause great trouble to the excavation.

If the direct method does not work, then the only indirect method can be used to cool down, that is, the steel pipe is drilled into the magma, the bottom end of the steel pipe is the same as a brick, but the center of this drill bit is hollow, the hollow area is drained, and there is a pipe at the upper end of the drill bit, which will be linked to the giant geothermal power station, and each giant geothermal generator is linked to tens of thousands of drill bits.

Geothermal power plants use water vapor to generate electricity, and at the same time, they also collect hydrogen, which is not stored and used in spacecraft as one of the fuels for flying into space in the future. Storage is needed to store some, but not so much, and the primary problem is sustainable cooling magma, then there can be no shortage of water resources, not very much at present, but it will be difficult to guarantee in the future, because the environment will become worse and worse in the future, the air pressure on the ground will become more and more thin, and the water resources will be sucked away by the asteroid spacecraft, at that time it will be difficult to find enough water resources for cooling, so it is necessary to establish a closed cooling system.

Therefore, on top of the giant geothermal power station, huge air-cooled pipes need to be built, which will be distributed on both sides of the hundreds of billions of tunnels, so that the air and walls of the tunnel can be used to absorb the heat in the pipes.

After cooling, the water vapor will turn into water, and then flow back into the reservoir of the geothermal power station, just enough to form a large circulation.

And this has the added advantage that the tunnel will not be too cold, and even after the eclipse program is launched, the ground will be covered with ice, and the area covered by the geothermal cooling pipes will not be too cold.

The combination of the temperature in the event space is guaranteed, the geothermal generators have recycled water, and the magma can be cooled down.

But there is a very acute problem here, that is, magma is magma after all, a change in the address may evolve into an uncontrollable catastrophe, and the main factor that causes the site to be active is the light emitted by the sun, these rays have many kinds of thermal radiation, among which the most important impact on the earth's core is the neutrino, which will heat the core, as long as it continuously heats the core, then the magma in the core will be very active, and the active magma is like boiling water, and the magma sealed in the depths of the ground, Just like boiling water in a pressure cooker, when it boils to a certain height, steam will gush out, and the performance of magma is similar to this, but because the magma is more viscous, it will solidify on the surface and become rock, which will block the vent of magma, so that the pressure is unlimitedly backlogged, knowing that the soil and rocks above cannot support it, and there will be a volcanic eruption at that time.

The current situation is that Tan Qiusheng needs a relatively quiet core, not a violent core, and the only way to keep the core from raging is to implement the eclipse plan and remove the heating factor of the sun.

As long as the core is stable, the magma will be less active, the geological structure will not be pushed from deep underground, and there will be no more earthquakes and volcanic eruptions caused by plate breaks.
