My Black Tech Shelter

After Lu Chen received Ling's notification, he also asked Ling to switch the screen.

Lu Chen was also surprised when he saw the picture displayed on the screen. His original idea was that five spacecrafts would drag a massive asteroid back.

This time the fleet came back and found that there were changes to the original plan.

"What's going on Zero?"

"Sir, after the spacecraft left Mars and headed for the asteroid belt, we discovered that the closest asteroids were either too big or too small.

Finally, after a little time of searching, I found these five asteroids of about the same size! "

"What are the parameters of the five asteroids?"

"Sir, the main material component of these asteroids is iron, and one half is made of gold minerals. Others include copper, aluminum, titanium, nickel, cobalt, manganese, etc. The most important thing is that a An asteroid full of water resources was also dragged back this time.

Among this batch of asteroids, apart from the two special satellites, there are three remaining ordinary asteroids.

Iron accounts for 50% of the total. Among the remaining substances, nickel and cobalt account for the remaining 40%, and the remaining 10% are other metal substances.

According to preliminary estimates, more than 5 million tons of iron, 300,000 tons of gold, more than 200,000 tons of nickel, 100,000 tons of cobalt, and about 50,000 tons of copper can be extracted from these asteroids. Aluminum, manganese and other metals,

The most important one is this water resource asteroid. It is initially estimated that more than 500,000 tons of water resources can be extracted in it, which can greatly meet the water needs of our lunar base."

"Great, now the lunar base will not be short of water in a short time!"

On Blue Star, a normal water consumption for a family of three per month is about 15 tons, which includes normal water consumption for cooking, bathing, washing vegetables, and washing clothes.

The current total number of people in our lunar base is about 500. Based on the water consumption of 5 tons per person per month, 500 people will need 2,500 tons per month.

500,000 tons of water resources are enough for these people to use for 16 years. Even if some industrial production requires a large amount of water, the remaining water is enough for these 500 people to use for about 5 years.

Moreover, if you continue to drag asteroids later, you can find asteroids containing a large amount of water resources again.

Thinking of this, Lu Chen felt a little regretful for not turning his attention to asteroid resources earlier.

Not to mention anything else, there are a lot of resources on the asteroids near Blue Star, although it is a bit more difficult to find them.

But didn’t Stars and Stripes find some asteroids before? It’s not a bad idea to set these goals. Lu Chen thought he could issue a good person card to Stars and Stripes Country.

Thinking of this, Lu Chen asked Ling to check the database to see which asteroids were near Blue Star.

By searching for information, Lu Chen discovered that these asteroids were not distributed between Mars and Blue Stars, but that their orbits would be close to Blue Stars, such as Eros, Spiritus, etc.

Among them, Ling Shen has a diameter of 252 kilometers. According to rough estimates, it contains nearly 5 billion tons of iron, 5000 trillion tons of nickel, and other rare metals measured in billions.

So looking at it this way, the metal output of the asteroid brought back this time is not much.

Fortunately, Lu Chen plans to use this asteroid resource himself and will not put it into the market, otherwise it may lead to the collapse of these basic industries.

However, although several asteroids have been transported back, smelting is still a big problem.

In order to have the ability to smelt asteroids, Lu Chen does not plan to mine like conventional mining methods.

Coincidentally, Lu Chen had seen an idea before, which was to build large-scale smelting equipment directly in space and use sunlight for high-temperature smelting.

If it were before, there might not be a way. After all, there is no gravity in space, and the metallic liquid cannot be aggregated.

But now that artificial gravity devices have been developed, gravity fields can be built directly in space smelting plants to provide forging conditions for metals.

Just do whatever comes to mind. Lu Chen asked Ling to open the holographic platform and start designing large-scale smelting equipment.

Since we only need to melt asteroids, the equipment can be relatively simple.

The first is several large lenses that can directly focus sunlight.

Then there is the reflective film, which can reflect sunlight, plus photon power generation equipment, electromagnetic equipment, etc.

Finally, after the design was released, there were still two days before the asteroid returned.

The principle of this equipment is to use dozens of large lenses to focus sunlight onto a single point on the central device.

In fact, it is a point, but the area is also very large.

Then the photon power station is used to provide electrical energy to the internal electromagnetic equipment.

After dragging the asteroid to the focus point, the asteroid begins to melt under the strong temperature, and then it is almost the same as the conventional smelting method.

As for the three metal substances of iron, cobalt and nickel, Lu Chen planned to use the magnetic properties of these three metals and use the magnetic field to adsorb the three metal substances, so that the three materials can be separated efficiently.

As for other metals, they can also be separated using their own characteristics.

Liquids in space are in a spherical state due to the lack of gravity. You can pile them together and then suck them away to cool them.

Looking at his design, Lu Chen nodded with satisfaction,

After deciding on the plan, Zero started to take action.

Building such a large space factory requires more than just a few reflectors and lenses.

A supercomputer also needs to be installed on site to control each local area.

Among other things, the melting point of iron is around 1500 degrees, while the boiling point is around 2800 degrees.

If there is no supercomputer for control, so many lenses on site can definitely increase the temperature of this area to about 10,000 degrees. By that time, not to mention the molten iron, it will all turn into gas.

Therefore, in addition to supercomputers, a large number of sensors, solar power stations, spacecraft docking platforms, etc. are also needed.

The asteroid will arrive at its destination in two days, so in order to save time, Lu Chen directly separated the spare warehouse and spacecraft docking port above the Venus Airport, and then used the moon's factory to manufacture 100 large lenses, each of which Lenses are thousands of square meters in size.

Concentrating sunlight requires a convex lens, so for long-term use, this lens has an edge thickness of 5 meters and a center thickness of 20 meters.

Around the periphery of the lens is a metal frame, with some micro-engines on both sides of the frame.

This is used to adjust the angle in space,

Then there is the large-scale solar reflective light film, which is attached to the metal plate, and the entire metal plate is not one piece, but is composed of many small metal plates.

In space, it can be controlled by a supercomputer to reflect sunlight to designated locations.

By the next day, half of the equipment had been manufactured, and the overall structure could be established. It was more than enough to smelt this asteroid.

Watching the spaceship carrying the equipment go away, Lu Chen also took the Origin and went to the scene together.

However, this action cannot hide the countries on Blue Star.

On Blue Star, qualified countries can see that the Venus Port, which was originally parked in the synchronous orbit of Blue Star, suddenly split into several parts.

About three parts detached from above. After regrouping in space, they began to fly to a place close to the sun, but not too far from the blue star.

Immediately afterwards, inside Lu Chen's base on the moon, dozens of continental-class spaceships arranged something underneath and set off together.

After zooming in, everyone saw a large convex lens missing from each spacecraft below. They didn't know what it was used for.

But looking at that part of the space station where the spacecraft flies, I know it must be something on some kind of equipment.

But with so many convex lenses, I don’t know what role they play.

Everyone observed patiently, and soon it was afternoon.

After seeing that the spacecraft was approaching the space station, many robots flew out from behind the spacecraft. These robots took out a large number of cables to connect the lens to the space station.

After completing this, a large number of metal plates were taken out of the spacecraft and pieced together.

As the metal plate gradually grew larger, everyone saw a large metal reflector.

The next step is the same operation, using very thick steel cables to fix the metal plate.

After everything was completed, everyone almost understood what Lu Chen was thinking.

We just want to build a space factory. Although it is very simple and does not even have a fence,

But the main functions are already there. If you add the control program, it will be an automated factory.

Coupled with the influence of no gravity in space, the smelted metal can be shaped at will, and its strength and toughness are much better than those smelted on the Blue Star.

However, Lu Chen knew that only the main structure of the current space factory was completed, and the corresponding sensors and supercomputers had not yet been installed.

Sensors are easy to talk about, but supercomputers are more difficult to build. Although there are a lot of quantum chip reserves, there is no spare supercomputer assembled.

Therefore, in order to ensure the progress of the project, Lu Chen directly ordered Zero to remove the central computer of a vacant laboratory in the main base.

Then modify the central computer to make it meet the requirements of the space factory,

Watching the spacecraft leave the space factory, the ground countries of Blue Star did not pay much attention. They only sent people to monitor the space factory and report any abnormal situations in time.

On Lu Chen's side, after seeing the spaceship return, he asked the robot to move the modified supercomputer onto the spacecraft.

Looking at the departing spaceship, Lu Chen returned to the base and asked,

"Sir, it is expected that the Second Fleet will arrive at the Space Factory after 5 hours of operation."

"Well, very good, you can pay attention there, I'll go back and take a rest,"

"Yes sir!"

It is now past eleven o'clock in the evening, and the fleet will return tomorrow afternoon.

And it was impossible for me to just wait for such a long time. Just after I got up from sleep, the space factory was almost up and running.
