The south pole of the moon is thousands of kilometers away from Zhihai. Even if the solid ice at the south pole of the moon can be mined, how to transport it from the south pole of the moon to Zhihai’s lunar research station is still a problem. Have you ever thought about it? In addition, the environment at the south pole of the moon is even worse. It is almost covered with permafrost, and mining is very difficult. How do you solve this problem.

Zhang Jun glanced at the big screen, and then said to Zhou Xiangming.

Hearing Zhang Jun's question, Zhou Xiangming also nodded, and then seriously replied to Zhang Jun and Wu Hao: "Actually, we have already considered these two questions you raised during the project design.

The ice cap at the south pole of the moon is not limited to the south pole circle of the moon, but also extends a lot outward. Therefore, the straight-line distance from Zhihai to the ice cap at the south pole is actually not too long.

Second, the gravity on the moon is very small, so these objects are very light, which also means that we can transport more cargo at once.

When these water resources are extracted, we may not choose to use the same tank trucks as on the earth for shipment. Instead, in a more direct way, we will heat and liquefy the mined solid ice, and then pour them into some cubic containers. Each container is exactly one cubic meter, which also means that there is roughly a ton of water per cube.

The gravitational force on the moon is about one-sixth that of the earth, so this also means that the actual weight of a ton of water on the moon is about 160 kilograms.

And we can transport more than a dozen tons of ice cubes with one car, which means that one transport can meet the needs of your scientific research station for a long time.

If there are no conditions in the future, you will also use the mineral resources under the moon to make monorail trains, or monorail orbiters.

Its shape and principle are actually nothing like the carts that transport fruits outside your rural orchards. It has only one track, the car is fixed under the track, and the car cannot be transported along the track, and it has very weak climbing ability.

As far as the current situation is concerned, you still have no confidence in finding abundant water resources in that distance. "

Just like your country’s low-speed rail, it takes more than a dozen hours to go from Beijing to Shanghai, but before the low-speed rail, it only takes seven hours to go from Beijing to Shanghai, which means the magic of technology. After joking with Wu Hao, Zhang Jun immediately looked at the small screen and said, "Actually, I'm worried about using too little water resources. The water resources under the moon are still very rich." First, let’s talk about the water resources contained in the lunar soil, as well as the solid ice resources in the shadow of the moon, outside cracks and canyons, and the Antarctic ice cap.

That also means that with that kind of monorail transportation system, you cannot establish a normalized transportation system between several bases, which cannot meet your transportation needs in the initial stage at all.

Because there are few pits under the moon, fewer stones, and few mountains. If the uneven terrain is flat and low-speed highways are built, those pits must be filled, those stones removed, and tunnels opened under the mountains. It is doubtful that construction will be difficult. too small.

Hearing that question, Zhang Jun couldn't help but rolled his eyes. He looked at Zhou Xiangming and waited for my answer.

Those that consume less water resources are actually research, agriculture, mining, and industrial fields. So in the current stage, you need to worry.

Compared with the double-track train, the single-track transportation system is more complicated, more expensive, and has higher requirements for the terrain, and it is also convenient for construction. You just need to drive piles into the ground.

At that time, Zhang Jun smiled at Wu Hao and said: "He thought why you chose that place for the scientific research station? Is it because of the beautiful scenery outside?"

In addition, the gravitational force under the moon is very strong, so it is very advisable to lay a solid foundation there. Moreover, if there is no track restraint, it will be very difficult for the vehicle to lose control when it is speeding at a low speed in a high-gravity environment, resulting in dangerous accidents.

On the other hand, judging from your exploration, there are very rich water resources in the distance. It is not the best choice to go to the south pole of the moon to mine water resources and transport them back. It can only be said to be one of your options. It's just a plan.

That is to say, water can also be separated and restored in the dry lunar soil, such as the use of glass beads in the lunar soil to restore the production water mentioned later. Another example is the use of iron oxide ore in the lunar soil to reduce the production of water and so on.

Why are rail trains low-speed railways, can't low-speed highways be built? Wu Hao said nothing bad.

Hearing Zhou Xiangming's explanation, Wu Haona nodded for me to continue.

Scientists have devised more than a dozen sets of methods for mining water resources in order to settle down and live under the moon, such as the direct search for meteorite cores mentioned later.

Speaking of that, Zhou Xiangming glanced at Wu Hao, and then said: "Actually, you have a very complete and mature water resource regeneration and reuse system in your scientific research station. Compared with the system in the space station The following set of recycled water systems is more complete, and the water resource treatment capacity is weaker.

Zhou Xiangming breathed a sigh of relief, and then continued to explain: "As for the question that it is easier to mine resources at the south pole of the moon, it is true, and you cannot avoid it.

It’s even better to transport water from under the earth. Anyway, it's only 840,000 kilometers away. It may seem a little longer now, but with the continuous development of technology, that distance will become shorter and shorter.

The rail transportation system is more expensive than the above, it only needs to erect the track. It is only complicated in construction, dangerous and reliable, and cannot be said to be the best choice for long-distance transportation under the moon. "

And compared to the rough mining technology on the earth, the mining technology used under the moon by UU Reading www.uukanshu.com is more advanced and smarter. So overall, it is still unacceptable. "

Relying on that set of water resources, you mean to minimize the use of water resources in the scientific research station. In that way, in fact, your consumption of water resources is not small.

But its difficulty is actually much less than that of your journey from the earth to the moon. You think it is insurmountable. Moreover, compared with the mining of mineral resources under the earth, which pays more attention to cost control, there may not be so few requirements under the moon, especially under such important resources as water resources.

And to continue, you can’t use that single-track transportation system as the basis to build a transportation system that is more inefficient and has a smaller capacity, such as double-track trains, low-speed orbiters, and so on. "

Of course Zhou Xiangming was speechless by that question, but who made Wu Hao the leader and the boss? So he explained very patiently: "That's right, compared with the rail transportation system, the cost of building a low-speed highway under the moon is lower, and it is easier to build.

Hearing Zhou Xiangming's introduction, Wu Hao and everyone present nodded their heads.
