Yan Dong's proposal for recycling the ocean is a very thoughtful one.
He proposed that as long as a parabolic mirror with a diameter of about 20 meters is used in the universe, a light spot with a temperature of more than 3,000 degrees Celsius can be obtained at the other end of the light pipe, so that the steam generated by the ice will push the ice back to the earth.
In fact, the Ocean Recycling Department has already thought of this solution, and they have already optimized it.
Over the course of five years, the Department of Ocean Recycling has perfected the technology and the required equipment has been made.
And the reason they haven't implemented it is because up to 18% of the ocean's water is lost in the process of high temperature dissociation.
In fact, the best way is to use a nuclear fusion engine, but humans currently cannot get controllable nuclear fusion on the ground.
So, after a long hesitation.
Earth is finally ready.
All mankind will fight to the death for survival.
...
A month later, the human project to recycle the ocean began.
In just one week, 800 large launch vehicles were launched from major launch bases around the world, sending 50,000 tons of payload into Earth orbit. Then, from launch sites in North America, 20 space shuttles carried 300 astronauts into space. Due to frequent launches along the same route, a long-lasting rocket trail was formed over the bases. From the orbit, it seemed as if a few threads were pulled into space from various continents.
This batch of launches has increased the scale of human activities in space by an order of magnitude, but the technology used is still from the early 20th century, which makes people realize that under the existing conditions, if the whole world makes a concerted effort to do one thing what will be achieved.
The three astronauts landed on a block of ice, and only then can the size of the block be felt.
The three of them seemed to have landed on a small crystal planet. Under the strong sunlight in space, the icy land beneath their feet seemed unfathomable. In the black sky, there are countless such crystal planets suspended far and near, some of which are still spinning. The surrounding ice cubes that are rotating or not rotating reflect and refract sunlight, and on the ice surface where the three cosmonauts stand, dazzling changes of light and shadow are constantly changing.
It was as if three little ants watched a crystal skyscraper collapse again and again.
After that, the operation starts.
An astronaut started the drilling trolley, the nose of the drilling trolley spun, and ice chips splashed outward in cones, glistening in the sunlight.
The drilling truck drilled through the invisible filter film on the ice surface and drilled into the ice surface like a screw that was screwed in, leaving a circular drilling hole behind.
As the borehole extends deeper into the ice, an elongated white line can be seen looming in the ice.
A total of four drilling holes were drilled into the depth of the ice by the drilling truck, and they all intersected at a point deep in the ice.
Next, the astronauts inserted three light guides into the three drill holes, and then inserted a jet tube into the fourth drill hole with a larger diameter, with the nozzle of the jet tube facing the direction the ice was running.
Then, the astronauts use a thin tube to fill some kind of fast-setting liquid between the light guide, the jet tube and the wall of the hole to form a good seal.
Finally, they unfolded the parabolic mirror.
The astronauts adjusted the protruding end of the light guide so that the light-receiving end coincides with the focal point of the reflector.
At the intersection of three drilled holes deep in the ice, a bright spot of light appeared, like a small sun, illuminating the mythical wonders of the large ice block.
The silver school of fish, the seaweed dancing with the waves... all of these maintained a lifelike posture when they were frozen in an instant, and even the strings of small air bubbles spit out from the fish's mouth were clearly visible.
In another ice block more than 100 kilometers away, which is also being recovered, the sunlight guided into the depths of the ice layer by the light pipe illuminates a huge black shadow, which is a blue whale with a length of more than 20 meters!
This is the ocean in the old days of mankind.
The steam quickly blurred the spot of light deep in the ice layer. Under the scattering of the steam, it became a white light sphere, which gradually expanded as the volume of the melted ice increased.
When the pressure reaches a predetermined value, the cover plate on the nozzle of the jet pipe is flushed, and a turbulent stream of steam is sprayed out rapidly. Because there is no resistance, it spreads in a sharp cone to the distance, and finally fades in the sunlight. Disappeared.
Another part of the steam entered the shadow of another ice cube, and was condensed into ice crystals, like a swarm of fireflies shimmering in the shadows.
The deceleration propulsion system on the first 100 ice cubes has been activated. Due to the huge mass of the ice cubes, the thrust generated by the system is relatively small, so they have to operate for as little as 15 days or more than a month to slow down the ice cubes. to the speed of falling into the atmosphere.
Before falling, the astronauts would once again board the ice to retrieve the light guides and mirrors. To ditch all 200,000 ice cubes, the equipment should be reused as much as possible.
...
Finally, after an unknown period of time, the perspectives of the audience in the heavens and the world finally returned to the earth again.
They returned to 'Yan Dong', as a spectator, aware of all this.
The former ocean floor plain was white, reflecting the strong sunlight.
It is as hot as hell, the ground temperature is close to 50 degrees Celsius, and the hot wind blows the salt dust, making the face hurt.
In the distance, there is a 100,000-ton oil tanker, the huge hull is slanted on the ground, and the propellers and rudders several stories high are covered with salt.
Then look at the continuous white mountains in the distance, which are underwater mountains that human beings have never seen.
At this time, the audience only heard a burst of cheers.
They all looked in the direction that everyone pointed.
So, the audience saw it.
In the silver ice ring that traverses the sky, a red bright spot appeared.
This bright spot floated out of the ice ring and expanded into a fireball. Behind the fireball was a white trail. The water vapor trail became longer and thicker, and its color was thicker and whiter.
Soon, the fireball split into dozens of pieces, and each piece continued to split. Each small piece dragged a long white tail. This white trail covered half of the sky. It seemed to be a white Christmas tree. On the branches of the branches is a small light shining brightly...
More icy meteors appeared, and supersonic sonic booms reached the ground like rolling spring thunder.
The old water vapor wakes in the sky are gradually fading, and new ones are constantly appearing, so that the sky is covered by a huge intricate white web.
Now, trillions of tons of water are back on Earth.
Most of the icy meteors broke up and vaporized in the air, but there was also a larger chunk of ice shards that fell directly to the ground, about 40 kilometers from where people were.
The undersea plain shook with a loud noise, and a cloud of white mushrooms rose up in the mountains in the distance. This large cloud of water vapor emitted a dazzling white light in the sun, and gradually spread with the wind, turning into a sky in the sky. The first cloud cover.
Afterwards, the clouds grew, blocking the scorching sun that had scorched the earth for five years for the first time, and covering the entire sky, making people feel a refreshing coolness.
Later, the clouds darkened and thickened, and the red light flashed in them, whether it was lightning, or the light of ice meteors that were still falling.
A drop of rain slapped on Yan Dong's face, as if it slapped in the minds of all the audience in the heavens and the world.
The long-lost cold feeling seemed to make everyone present extremely excited.
It's raining!
It was a heavy rain that was rare even when there was sea, and Yan Dong and others cheered and ran wild in the rain, and they felt their souls melted in the rain.
But then everyone had to hide in the car or in the helicopter, because then people would suffocate in the rain.
The rain didn't stop until dusk, and many puddles appeared on the seabed plain, and the setting sun that emerged from the crevices of the clouds shone with golden light, like the eyes of the earth just opened.
Yan Dong followed the crowd, stepping on the sticky salt slurry, and ran to the nearest puddle. He picked up a handful of water, sprinkled the heavy saturated salt water on his face, let it flow down with the tears, and choked out:
"O sea, our sea..."
...
The video is here, and at the end, the curtain has come to an end.
After watching the entire video, the feeling it brings to the people of all worlds is no longer a shock to the scientific and technological strength of a civilization.
This is a shock that cannot be described in words.
When they saw the emergence of cryogenic artists, they were also shocked when they saw the amazing technology and capabilities of cryogenic artists beyond human imagination.
But they can also feel the misery of the earth. When faced with the manipulations of cryogenic artists, all human beings are so powerless.
It is not difficult to see that this may be because this time, the audience's perspective has shifted to the human being "Yan Dong".
Yan Dong has no power, his only power is "art", but this power has no effect when facing cryogenic artists.
Cryogenic artists brought art and destroyed civilization.
And they finally understood why this time, the low-temperature artist's inventory video fell on a human named 'Yan Dong' to watch as their perspective.
Because he is Yan Dong, he is Yan Dong.
Yan Dong, severe winter.
There is a severe winter in Yan Dong's heart.
Yan Dong is in love with ice and snow, and is fascinated by it; the harsh winter is wrapped in ice and snow, like a dream.
But this severe winter can only be a severe winter for human beings.
Cryogenic artists from dark matter clouds also love harsh winters.
It's just that this severe winter is close to the absolute zero of minus 273 degrees Celsius.
The cryogenic artist took all the seas on earth and created the sea of dreams.
The sea became a glacier around the earth.
Beautiful, like God jumping through the air.
However, humans, including artists, lost almost all the water on the planet.
Humanity will die.
Artist Yan Dong returns to his profession and becomes one of the thousands of engineers who save the planet.
Other artists died, and no one talked about art anymore.
The only human monument involving art was dismissed by the long-haired artist as "there is no descendant, and a bird monument is still erected?"
All people care about is water and survival.
Fortunately, humans still have a chance.
When I see scientific researchers working hard for the ocean of space.
The fate of countless human beings is all bound to these scientific researchers.
When people all over the world are waiting for the ice in the sky to turn into rain and return to the world.
At this moment, the audiences in the heavens and the world were all moved by this.
In the videos of cryogenic artists, they see the indifference of advanced civilization.
But they can also see the cohesion of lower civilizations in it.
Whether or not these humans were once enemies together.
But in the face of a crisis for all mankind.
They united and displayed a cohesive force that no one could ignore.
Perhaps human beings are weak when faced with cryogenic artists.
But they never give up.
At the end of the video, viewers can see Yan Dong standing on the frozen river in winter.
With the efforts of Yan Dong and other engineers, human beings finally recovered 82% of the ocean.
However, the Earth re-entered an ice age.
On the banks of the Songhua River, Yan Dong and the ice and snow artists gathered again, thinking of the words of the low temperature artist.
So they talk about art together.
"Art is the only reason for civilization to exist!"
[With the development of civilization, art flourishes]
[If civilization is in danger, art will die first]
[When civilization escapes danger, art is reborn]
In that all-knowing and almighty voice, the video finally ends.
Perhaps many years later, the video wrapping is over.
And the audience in the world looks back on the past, and they will always remember this moment.
