If he wants to contact the outside world and receive broadcast or shortwave signals, Chen Xin must set up the prepared antenna so that he can gain contact with the outside world.
To do this, it would be possible to at least wait until the wildfires outside were completely extinguished, the temperature dropped, and Chen Xin could open the door of the shelter and walk out.
However, according to Chen Xin's estimation, it may take at least a month to wait for the outside temperature to drop and the mountain fires to be extinguished.
But if we just wait for the impact of the EMP shock wave to dissipate, it will be enough in a few days.
The so-called EMP means electromagnetic pulse, which is a sudden, high-intensity pulse of broadband electromagnetic radiation. The electromagnetic pulse usually only lasts for a few minutes at most.
Electromagnetic pulses are usually caused by nuclear explosions, lightning, sunspots, conduit effects or electrical sparks. Old-fashioned TVs can be damaged by lightning during thunderstorms because the electromagnetic pulses caused by lightning burn the electronics inside the old TVs. element.
Normally, the duration and impact time of electromagnetic pulses are very short, but this time the electromagnetic pulse was caused by meteorites disrupting the ionosphere. Its duration is obviously longer than the duration of electromagnetic pulses caused by nuclear explosions or lightning. longer.
The main reason why Chen Xin waited for so many days was that in addition to the main large meteorite, there were also many small meteorite fragments and materials thrown into space by the meteorite impact.
These meteorite debris and materials lifted into space will continue to fall within days to weeks after the meteorite impact, continuously causing ionospheric disturbances and causing electromagnetic pulses.
Therefore, if you want to avoid damage to electronic products, it is safer to wait a few more days.
Of course, this cannot wait indefinitely, because the meteorite debris formed by the impact of the material launched into space with the meteorite may not fall cleanly even in the next hundred years, and their disturbance to the ionosphere will also be It will still continue, but the disturbance caused by these debris and dust will not be very large.
Large pieces of meteorite debris and materials lifted into space will fall first, and their disturbance to the ionosphere will have a global impact. When these large pieces of material fall, the remaining small pieces of material will not only The falling time will last for a long time, and the impact of the electromagnetic pulse caused by it will be much smaller and can basically be ignored.
According to Chen Xin's estimation, it will take about a week for these large pieces of material to fall, so if he wants to unblock his electronic products, he will have to wait for about a week.
Because the large pieces of material have fallen, even if the remaining small pieces of material can cause EMP shock waves, they will not affect the electronic products in the shelter due to the hundreds of meters of soil above the head.
This can be judged from the fact that at the beginning, the light bulb would flash non-stop all day long, which could even burn out the light bulb, but now it only flashes once every few hours.
However, although he only needs to endure it for a few more days before he can take out his mobile phone and computer to play, Chen Xin still feels very bored now.
This is an underground shelter. Although Chen Xin did not dig very deep, the hundreds of meters of soil above his head not only protected his shelter from various disasters, but also isolated almost all sounds from the outside world.
In fact, if Chen Xin hadn't been alone all year round due to his career, and had become accustomed to a relatively lonely environment, if he stayed alone in such a very quiet environment for a week, I'm afraid he would be the same as those who were recruited in the army. It’s the same as those in solitary confinement.
It was too quiet here, and the lighting could only rely on lights. After turning off the lights, Chen Xin couldn't even tell whether he was in day or night.
If it weren't for a mechanical pocket watch and the system's daily settlement as a time reference, Chen Xin really felt that if he stayed for a few more days, he would be confused with time. He would have no idea how long he had been here and whether it was day or night outside.
Although due to the impact of the meteorite impact, the sky outside should have been obscured by dust, and the sun will not be visible for hundreds of years. There is no difference between day and night at all.
Chen Xin tapped his forehead and suddenly felt that he should have bought a smart window. Of course, it was not the kind of smart window that automatically adjusts light and ultraviolet rays, but a smart window that can change the scenery.
A display screen can show different scenery according to different time periods. For Chen Xin, who is isolated from the outside world underground, it is simply a must-have for physical and mental pleasure.
And with the advent of the long night and cold winter, after the surface of the Blue Star has been devastated by global fires, it is obvious that the scenery of the past with the singing of birds and the fragrance of flowers has become extinct. Leaving such a window that allows people to recall the beautiful past is undoubtedly a kind of commemorate.
It's just that Chen Xin obviously didn't consider this at the beginning, so now he can only stare at the cold ceiling in a daze.
Otherwise, even just looking at the grass and woods in a daze will make people feel happier than the ceiling in front of them.
Of course, without smart windows, Chen Xin can't change one. Maybe when upgrading the room in the future, through the overall upgrade of the room, more such equipment can be added, but now Chen Xin feels that he might be able to upgrade the lighting system first. .
Add intelligent functions to the lighting system, adjust the light intensity and color according to the time, so that you can feel the changes of time even in the underground shelter. This is undoubtedly much better than the current rigid fluorescent tubes.
Moreover, with the change of time, you can also plan your time better and avoid living in such a hazy state.
Thinking of this, Chen Xin took out his notebook and wrote "illumination" on the page where food and medical care were written.
But if you upgrade the lighting, will it increase the power consumption
After Chen Xin finished writing about lighting, he paused with his pen. After thinking for a moment, he inserted the line about power supply in front of lighting.
Although the power consumption of the shelter is not very large now, and the generator is not running at full capacity all day long. Most of the power generated is stored in the battery. However, considering the increase in power consumption caused by the upgrade of various equipment, the upgrade of the generator It should also be taken into consideration.
Just upgrading the generator will undoubtedly mean increased fuel consumption. How long can the three tons of gasoline stored in it last
Chen Xin is thinking about this problem seriously, but it does not have to be too troublesome to solve. Whether it is to wait for the external environment to stabilize, go out to find people to exchange supplies for fresh vegetables according to the original plan, or to upgrade the power supply system through the system to use fuel to generate electricity. Upgrading the power generation equipment to higher-tech or even black-tech power generation equipment are all ways to solve the problem. (End of chapter)
