MTL - The Return of the Black Technology of Immortal World-v3 Chapter 285 expand
At the same time, the Moon Palace base also started a substantial expansion immediately.
In fact, in the past three years, the base has never stopped expanding. The area has expanded from a few thousand square meters in the beginning to 30,000 square meters now.
However, some of the 30,000 square meters were later increased to less than one percent of the original volume of the base. Naturally, most of the rooms in the base have undergone space expansion.
Space expansion is a very advanced technology, which requires multiple rune arrays to be engraved on each wall. There are also certain requirements for materials, which can support the expanded space and prevent it from collapsing again.
At that time, it was specially made to allow the base to carry as much supplies as possible when it left Blue Star, and to plant those plants.
After arriving on the moon, there is no need to fly again from the Moon Palace base, and the land on the moon is almost infinite, so naturally there is no need for space expansion.
And the minerals on the moon are far easier to mine than those on the blue star. It is basically a barren virgin land. If you walk around casually, you may pick up a piece of iron, even if it is gold and silver.
Obviously, it is impossible to build reinforced concrete buildings on the moon, because the vacuum environment on the moon will make the moisture in the concrete boil and evaporate immediately, thus forming a large number of holes inside. The steel bars have almost no support at all.
Therefore, on the moon, metal is the first choice to serve as the skeleton and skin of buildings, especially after the base can easily smelt metal.
The multi-layer interlayer air-adhesive building skin coated with high-strength weather-resistant sealant is firmly fixed on the metal frame by bolts, just like building a prefabricated house, and a large-scale base factory building can be built soon.
Then all the contact parts are welded together using vacuum low-temperature laser welding technology, which can also meet the airtightness of the building in a vacuum.
In fact, even if you don't weld it immediately, after a long time, metals with smooth surfaces will stick to each other and even fuse together.
For these buildings, Yang Qing's requirement is to be sturdy and durable, and have the best thermal insulation and sealing performance, so as to avoid the waste of air.
On the moon, the waste of energy is nothing. The solar panels that are expanding every day have already made the energy of the moon to an inexhaustible level.
During the day of each moon, a large amount of solar energy is stored for base use at night.
Controlled fusion reactors are being built all the time, but they are only used to supplement those metal smelting and occasional energy shortages in industrial production.
As the core of the solar system and the largest natural fusion reactor, the energy of the sun can be said to be endless, and what humans use is only one-two-two-billionth of it, which is as high as 1.49 times E to the 22nd power joule.
It can be said that as long as the energy of the sun is utilized, it will be tens of thousands of times stronger than all the energy used by humans today.
That's why there are Dyson rings and Dyson spheres, which surround the sun and use solar energy.
However, this device actually has a fallacy. The sun occupies 99% of the mass of the entire solar system, and the remaining eight planets, as well as dwarf planets, and asteroids account for less than 1%.
Even if all the materials are used, the Dyson sphere is difficult to construct.
Therefore, the first necessary condition for building a Dyson ring is to be able to easily obtain materials from extraterrestrial systems, and there are more than one, because other planets are similar to the solar system, and stars occupy most of the mass, and only those planets can be used.
However, being able to easily travel to and from other galaxies, and taking away the power of planets, the use of energy is far from what Yang Qing can match now. It seems that he doesn't like low-quality energy bodies like stars.
Of course, building a Dyson sphere is also an unattainable dream for Yang Qing, but point-shaped space stations with low requirements, orbiting the sun, may be built in the future.
Because Yang Qing has an energy storage material, Lingshi, which is completely different from the Blue Star battery.
Although the energy storage capacity of elementary spirit stones is not very high, the energy contained in intermediate spirit stones is several energy levels higher than that of elementary spirit stones.
With the beginning of the operation to add weight to Mars, a large number of asteroids must be found.
When an asteroid is found, it will also be scanned for mineral resources, just like the gold or platinum asteroid that was glimpsed in the asteroid belt, naturally it cannot be simply thrown on Mars.
In fact, as a high-density metal at the end of the periodic table, platinum has great uses.
Lead, as the main component of spiritual energy isolation materials, is actually somewhat unqualified.
Because the texture of lead is too soft, and its chemical properties are extremely active, it is easy to cause pollution.
In fact, gold has the same characteristics as it, but it is too little on the blue star, even if it is stored on the moon, it is not rich.
The gold-based isolation aura formula has been successfully tested on Blue Star, but it is not easy for a person to buy tens or even hundreds of kilograms of gold.
But when this number rises to one ton or two tons, it will not be so easy.
Not to mention whether Yang Qing had that much money at the time, after all, the price of a ton of gold was only about 300 million Chinese yuan.
The main thing is gold, which has always been a symbol of currency. Before the middle of the last century, gold was a reserve for currency issuance. It was not until the collapse of the Bretton Woods system in the United States that it began to decouple from gold.
If you buy too much of this thing privately, you will face the trouble of being investigated, and Yang Qing is the most afraid of trouble, so he took a step back and used lead on the Moon Palace Base. Of course, the lead is all inside the bulkhead. There will be no direct contact with the interior.
And the same elements that are scarce on the moon and the blue star will not be so scarce in the universe, and then the intermediate spirit stones may be as flooded as the primary spirit stones.
This is Yang Qing's confidence in preparing to develop the sun~www.novelbuddy.com~ But all of this is behind the Mars project.
Looking for raw materials for refining intermediate spirit stones is just incidental, and the purpose is to increase the weight of Mars.
For this purpose, the substantial expansion of the Moon Palace base has become a matter of course.
Although the surface of the moon is in a vacuum state, it may be cleaner than the clean room on Blue Star, but those robots, as well as spacecraft parts, cannot be produced in the open air, so a large factory building was built immediately.
Because of the relatively low gravity of the moon, these buildings are multi-storey, with a height of more than 100 meters. , all have enough space, and the upper layer can even carry some taller tree-type fruit trees.
The advantage of being on the moon is that because there is no air, there is no need to consider the influence of air convection. As long as it can not collapse in the face of generally low-level moonquakes, then there is no danger.
Therefore, in the buildings on the moon, the bottom layer generally occupies a large area, and then the high-rise buildings facing the sky.
In the building, the internal metal frame is the iron alloy that is most easily found on the moon. Although its adaptability to temperature range is still a bit worse than that of titanium alloy, but in terms of strength, it is not inferior to it.
After all, it is not the iron alloy used for spaceships, and it is not exposed to the outside for a long time. During the rest of the time until the building is abandoned, the inside of the building will maintain a nearly constant temperature.
