At Ningcheng Xinghai Aerospace Industrial Base, Liu Yuan was pulled over by Wang Chen.
Today is the day when Xinghai Technology’s first space solar power station starts construction. This space solar power station will be the first space solar power station in human history, which is a very historic moment.
However, Xinghai Technology is very low-key right now and has not notified any news media about this matter. That is to say, internal generals Liu Yuan and Lu Yong have been invited to attend the groundbreaking ceremony.
There is no way, it is impossible not to keep a low profile now.
Times have changed. In the past, you needed to be high-profile to show off your powerful technology. Now that you are big and attract attention, you need to be as low-key as possible and not attract attention.
In the huge control and command center, many scientists and engineers are extremely busy, making relevant preparations. At the same time, in space, the space city built by Xinghai Technology is also extremely busy, with a large number of scientists and engineers making preparations.
.
"Wang Chen, I told you to pay attention to space debris. Do you have any good solutions here?"
Liu Yuan looked at the busy figures of everyone and asked after thinking about it.
With anti-gravity technology, it is not difficult to build a space solar power station in space. What we really need to worry about is the garbage in space.
Space debris may be an issue that many people have not paid attention to.
In fact, since humans launched the first artificial satellite, there has been more and more garbage in space. These garbage come from scrapped satellites in space, discarded spacecrafts from space activities, launchers, burning debris, etc.
This kind of garbage can be said to be in the past. It is often relatively large and very easy to find and detect. However, some experimental anti-satellite weapons exploded satellites in space into countless pieces. This kind is very small and extremely
Hard to find.
Space junk often moves at an orbital speed of several kilometers per second, carrying huge kinetic energy. If a space station, satellite, spacecraft, etc. in space collides with it, it will be seriously damaged.
Spacecraft endanger the safety of astronauts, and may even directly cause damage to spacecraft, space vehicles, satellites, etc.
It can be said that space junk has gradually become an important threat to human exploration of space.
From the time humans launched the first satellite until now, the world has carried out tens of thousands of space activities, producing a large amount of space junk, most of which was sucked into the earth by gravity and burned up in the atmosphere, but still
There are more than 5,000 tons of space junk left in orbit.
These space junks are huge in quantity, widely distributed, and pose a great threat. They not only pose a threat to space stations, spacecrafts, satellites, etc. in space, but are also very likely to pose a threat to the ground.
But all the time, countries around the world have been unable to deal with space junk. Because it is in space, it has always been difficult to clean up. The cost of cleaning up is also very huge, and there are more and more junk in space.
"Boss, we also use three methods to ensure the safety of space solar power stations."
"Our satellites and detectors scattered throughout space can detect all space junk in a timely manner. Once we discover that space junk may pose a threat to our space architecture, we will activate emergency plans."
"The first way is to change the orbits of spacecraft, space stations, and spaceships in space to avoid the impact of space junk. The advantage of this method is that it is simple and saves trouble. The disadvantage is that our space stations have slowly become
Space cities are becoming larger and larger in size and mass, making orbit changes more and more difficult and consuming more and more energy."
"The same goes for solar power stations. They are too large, more difficult to change orbit, and consume more energy."
"The second method is to use a spacecraft to capture the space junk in advance and clean it up. This method is simple to operate. We have anti-gravity spacecraft, so it is not difficult to capture space junk in space."
"The third way is to directly destroy this space junk. Taking advantage of the characteristics of the solar power station, when we detect that space junk poses a threat to the space solar power station, we can use lasers to ablate it all in advance, or else
It is to adjust the other side of space solar power generation, the side containing the mirror, and use the high temperature generated by the polymerization of sunlight to directly vaporize space junk."
Wang Chen sent a piece of information to Liu Yuan and Lu Yong's virtual machines, and also introduced in detail the three plans he had formulated.
Space junk is very harmful and requires great attention, but with the current technology of Xinghai Technology, it is still very easy to deal with space junk.
"Not bad."
Liu Yuan read the information carefully and felt that these three methods are quite good and can indeed solve the problem of space debris very well.
First think of a way to hide. If you can't hide, then think of a way to capture it. It's not very convenient to capture it. I might as well just use lasers to destroy you. If the space junk is a bit big, you can also use solar energy to vaporize you.

"This space solar power station is not only a power station, but also a space smelting factory to prepare for smelting asteroids in the future."
"So the lens on it has two sides. One side is a solar panel used to generate electricity, and the other side is a mirror that can emit sunlight. It is usually used to generate electricity and obtain energy. When it needs to be used to smelt asteroids, it can be flipped over to use the other side.
to emit sunlight."
"Each of its solar panels can be controlled by a computer and rotated at will. No matter what angle it is, it can ensure full vertical reception of sunlight and ensure the amount of electricity generated."
"At the same time, it can also automatically calculate the angle to reflect and aggregate all the light at one point. The high temperature it generates can exceed tens of thousands of degrees, which is enough to vaporize any object and metal."
Then Wang Chen also began to introduce the situation of this solar power station to Liu Yuan and Lu Yong in detail.
"In space, its power generation efficiency can reach hundreds of times that on earth, which is very profitable..."
In fact, it sounds high-end, but in fact it is a very simple thing without much technological content.
It is to build a huge solar power generation frame in space, and then subdivide this frame into standard one square meter solar power generation panels.
This solar power generation panel is also specially made. One side is a solar power generation panel and the other side is a mirror that reflects sunlight.
It is very simple to produce and has no technical content. The technology on earth has already been able to produce this thing.
What is really difficult is to send it into space and build such a solar power station in space.
In the past, this would have been impossible.
The cost of relying on rockets and spaceships to travel to and from space is too high. The key is that there are huge restrictions on the mass and volume of the objects carried. Building a solar power station in space, even if the power generation efficiency is hundreds of times that on the earth, is a little
All cost-effective things.
But it’s different with anti-gravity technology. Anti-gravity spacecraft can easily carry a large number of objects to and from space. The cost of building a space solar power station is not much higher than that on the earth, but the power generation efficiency is higher than that on the earth.
Hundreds of times more efficient.
This is very profitable. The key is that it can also be used to smelt asteroids in the future, which has many uses.
It can even be used as a weather weapon whenever necessary.
Mirrors that can emit sunlight are used to emit a large amount of light to the earth. As long as there are enough mirrors, the temperature of a place can be raised to extremely terrifying levels in a very short period of time.
You can also turn night into day, turn cold areas into tropical areas, etc. Of course, the premise is that there are enough emission mirrors and enough light is emitted to the earth to achieve all this.
If it's just a small amount of reflection, the impact won't be big.
However, as long as it is profitable, space solar power stations are very efficient. In space, there is no difference between day and night. This alone cannot be compared to the power generation on earth.
In addition, the light in space has not been weakened by the earth's atmosphere. Its intensity is several times that on the earth. At the same time, it can always maintain vertical illumination and is not affected by wind, rain, clouds, etc.
Calculated, the efficiency of solar power stations in space is hundreds of times that of solar power generation on earth. This is why satellites and space stations can obtain enough electricity with just two small wings.
Now the best monocrystalline silicon solar power generation panels can generate 0.2 kilowatt hours per hour, which is 0.2 kilowatt-hours of electricity. Of course, this is on the earth. If it is in space, because there is no weakening of the atmosphere, the intensity of sunlight in space
It is more than ten times that on the ground. If we calculate it as 10 times, one square meter of monocrystalline silicon solar power generation panel can generate 2 kilowatt hours of electricity per hour in space.
In space, we can generate electricity 24 hours a day without any gaps. It will not be affected by day and night like it is on the ground. Solar power panels can work 24 hours a day under the best direct sunlight. The power generation efficiency is quite good.
To do a simple calculation, 1 square meter of solar power generation panel can generate 2 kilowatt hours of electricity per hour in space, which is 48 kilowatt hours of electricity 24 hours a day.
48 kilowatt-hours of electricity a day, 365 days a year, is 17,520 kilowatt-hours of electricity. This is just the power generation of one square meter of solar power panels.
This time, Xinghai Technology is planning to build a space solar power station with a length and width of 10,000 meters. Its area is 100 million square meters, which means that there are 100 million solar power panels per square meter to generate electricity all year round.
Theoretically, the annual power generation can reach 1,752 billion kWh!
