Of course, Regers was surprised, even if the two settlements in the Northeast of Steel were built so well, after all, the environment of Northeast China was indeed blessed with unique resources and materials.

But this is the Gobi Desert! And in the depths of the vast Gobi!

The natural environment is worse than where they established their colonies in America! It rarely rains throughout the year, and there is no one in the surrounding area! Apart from stones, there are simply no resources to exploit.

But the people of the Iron Castle were able to build such a green and vibrant city in such a place! How could this not surprise Regess.

So he immediately excitedly asked Chen Yuan how they had built such a magical city here and under such conditions.

You know, this is a great reference for them.

In the face of Regers' question, Chen Yuan smiled and said: "This is actually nothing, we just built the entire settlement into a greenhouse." ”

"Greenhouse?" Regis and Wang Ruhan both said in surprise.

"That's right!" Chen Yuan pointed to the sky and continued: "We are actually covered with glass on it. ”

He looked around and explained to the people in the car: "You see, the walls around our settlement and most of the tall buildings in the settlement are almost the same height. In this way, we can build a huge roof over the entire settlement, just like a house. The surrounding walls are the load-bearing walls of this 'greenhouse', and the tall buildings in the middle are the pillars. As for the ceiling, we use glass. This allows light to penetrate and locks in the temperature and moisture within the settlement. Isn't it just a greenhouse? ”

Listening to Chen Yuan's explanation, Regis and Wang Ruhan couldn't help but look around, take a closer look, and sure enough. They all nodded knowingly.

However, not all the buildings in the Iron Fort settlement are the same height. It's just that the tallest buildings are all the same height. They are evenly distributed throughout the settlement.

There are many other buildings of different heights. This makes it easier for light to be further reflected and diffused within the settlement. At the same time, it also makes the whole settlement appear more layered and beautiful, and will not be too monotonous. In addition, a large number of green plants are planted on each building, making the whole settlement look like a forest city and a paradise.

At this time, Chen Yuan went on to introduce: "Moreover, you all know that this is the Gobi, and there are often winds and sands. When it was scrapped, it was simply obscuring the sky. Just open your mouth and you'll be able to eat enough sand. So we built this glass roof to actually protect against wind and sand. ”

He laughed self-deprecatingly: "Otherwise, there is no way to live this life, and it is estimated that it will be difficult for the plants that are planted to live." ”

Wang Ruhan and Qin Cheng couldn't help but nodded, they actually knew this when they were in the Northern Capital.

In the last century, in order to develop the economy rapidly, China neglected environmental protection, resulting in serious damage to the natural environment.

Especially in North China and Mongolia Province.

Large areas of the mountains and forests have been cut down and turned into a bare state. Just like the previous Black Wind Mouth, it has also been a little better in the past few years, after the hard work of the military and civilians in the Shenwuguan settlement.

At the same time, large areas of grassland have been degraded into deserts due to overgrazing.

As a result, every year in spring, there is a wind and sand in the north. And the northern capital is also nearby, so it will be affected.

Every time the weather is windy and sandy, everyone has to cover thick masks when they go out. Sometimes when you come back from a door, the white mask turns black.

And if the doors and windows of the room are not closed properly, it will only take a while to accumulate a thick layer of dust all over the room.

So Wang Ruhan couldn't help but ask curiously: "Then what to do with the sand on your roof?" Aren't you afraid of being crushed by the wind and sand? ”

In this regard, Chen Yuan explained with a smile: "We actually have a way to do this. On the one hand, in fact, the roof here is not completely horizontal, but has a certain inclination angle, basically high in the east and low in the west. ”

Chen Yuan demonstrated to the crowd with gestures: "And the wind and sand here are generally blowing from the west. In this way, most of the wind and sand will be blown away along the glass roof and will not be deposited due to leeward. ”

Taking a step back, he says, "Even with a small amount of sedimentation, we installed a slight vibration device under the canopy. This will shake the sand on the roof. ”

"And our roof has a certain angle of inclination, and these vibrating sand will flow down the roof like flowing water."

"Finally, when the weather is fine, we will send someone to the roof to clean up the sand, and it will be basically fine! Moreover, the glass we choose is high-strength plexiglass, and the area of a single piece is not large, so people will be fine if they step on it, and of course they will not be crushed by the general wind and sand. ”

Wang Ruhan nodded, and Regis asked at this time, "Then how do you solve the problem of summer?" It's hot in the summer, right? If you add glass, it's even hotter. But if it is opened, the water vapor will evaporate very quickly, how can these plants survive? ”

Chen Yuan said with a smile: "We are also covered with glass in summer here. However, in the summer, we will switch to reflective glass with poor light transmission. In this way, most of the light is reflected, lowering the temperature in the settlement. ”

"And we're also thinking about replacing these glasses with smart glass recently. It is the kind of glass that can artificially adjust the light transmittance. Then you don't have to go through the hassle of changing it every year! It's just that before, our technology and production capacity were limited, so we could only use ordinary glass first. ”

"Also." Chen Yuan continued: "There are actually a lot of opaque solar panels above our heads. It's just that these solar panels, which are installed on top of the walls and buildings, do not interfere with the daily lighting of the settlement, but can be used to generate electricity. Although this part of the electricity is not enough to meet the daily electricity consumption of the entire settlement, it can be used to drive the central air conditioning of the settlement and assist in the temperature regulation of the settlement. Reduce the amount of coal used in our thermal power plants. ”

"Awesome!" Regers exclaimed, "You're a typical eco-friendly city here!" ”

At this time, Wang Ruhan asked again: "Then where does your water come from?" With so many plants, fruits and vegetables here, you need a lot of water for watering, right? There is also the daily water supply of more than 100,000 soldiers and civilians here! And this is the depths of the Gobi! Where did you get so much water? ”
