The moon has no water and no oxygen. Since the mass of the Moon is too small, the gravitational pull generated is not enough to form the atmosphere. So, the moon belongs to a vacuum. Therefore, it can only be created in a closed building to create an environment suitable for the people of the earth.

Planetary migration, water and oxygen are indispensable.

Perhaps, the transfer of the earth's water resources to the moon seems to be a feasible method. As for how to divert water, in addition to using the space shuttle, building a "space ladder" seems to be a good choice.

The concept of a "space ladder" was proposed in 1970, and in 1999, NASA's Marshall Center's Advanced Office published an article entitled "The Ladder: Advanced Infrastructure in Space," marking the transition from fantasy to reality! Dr. Brad Edwards of the Fairmont Institute for Science, who is known for his research on ladders, wrote in his paper: "Ladders can make human history leap forward." ”

Once the "space ladder" is built, it will be able to carry out transportation work around the clock, send tourists and goods into space, and greatly reduce the cost of transportation. Today, a rocket launch or space shuttle transports about $20,000 per kilogram of payload, while a space ladder transports only $10 per kilogram of items, enabling space technology to leapfrog development.

The structure of the space ladder mainly includes a base, a cable belt, and an elevator compartment.

The pedestal can be chosen at the equator, so that the distance from the geosynchronous orbit is the shortest. And the elevator warehouse is not difficult. The most difficult thing is the cable, because the cable has to pull the capsule, and the pull is the strongest, and if the cable can't withstand it, it will break. Therefore, the material problem of the cable belt is the biggest factor hindering the development of space elevators. The most promising material is carbon nanotubes, which can withstand the same amount of tension as a space elevator.

This "carbon nanotube" is nothing else, it is graphene! But it is made of graphene sheets rolled in layers, and according to the number of layers of graphene sheets, it can be divided into: single-walled carbon nanotubes and multi-walled carbon nanotubes.

Because graphene has been developed by Henry in advance, and the technology to make graphene is still the latest technology in 2015. Therefore, the manufacturing and development of graphene has greatly accelerated the development of current science and technology.

In previous lives, the United States and Japan were most obsessed with the study of the space ladder. In addition to NASA in the United States, the famous Google company is also conducting this research! As for Japan, they have even invested $7.3 billion in the development of their own space elevator technology, hoping to take the lead in this field. In fact, it is not difficult to imagine that whoever builds the first space elevator first is almost equivalent to winning the ticket to colonize outer space. If you have a little ambition, you will not let go of this opportunity! Little Japan is very ambitious, but its own land is only the size of a palm, and of course it wants to colonize other places!

However, space ladders are not so easy to make. Even with the strength of Super Materials, there is no hope in the short term. One of the biggest difficulties is that the current nanotechnology is not advanced enough to make suitable carbon nanotubes from graphene!

However, Henry was not in a hurry, and if he took his time, it might not take twenty or thirty years to build a space ladder on Earth, but on the Moon, it would be much simpler. The gravitational pull of the moon is very small, and the tension of the cable belt of the space ladder is also very small, and it may be more than ten years before the moon space ladder can be successfully made.

In fact, you don't have to rush to make a space ladder. Water is so scarce that there are many places where water is not even needed. If Henry diverted fresh water from the earth to the moon, the fresh water on the earth would be even more insufficient. Therefore, the first problem that Henry has to solve is the problem of water scarcity on the earth!

Huining, Gansu Province, China, is said to have bathed only three times in their lives, and the severity of the water shortage can be seen when they are born, married, and died.

Water scarcity is like a witch's claw, choking the throats of many countries. And with the increase in population and the increase in industrial water use, water resources will only become more and more scarce! According to scientists' analysis, the future output value of water resources may reach hundreds of billions of dollars!

Currently, the Earth's oceans cover 70.8% of the total surface area, and the average depth of the oceans is about 3,800m. So, in addition to the freshwater resources that can be used directly, there is no doubt that the best way to obtain freshwater resources is through desalination. In addition, the air also contains a lot of moisture, and the other thing is sewage purification.

If the "water-making artifact" can be invented, then both the income and the international influence will increase dramatically!

Think of the oil-rich Middle East, where fresh water is scarce and even more precious than oil because of its desert location and large population. Even if it's a bucket of water for a bucket of oil, they're willing!

If there is a "water-making artifact", maybe at that time, Henry will consider buying a large piece of land in Africa to carry out "African development" and create an independent kingdom!

……

Henry temporarily owns the British Thames Water Company, a company mainly engaged in sewage purification. However, "it is difficult for a good woman to cook without rice", and many countries do not even have sewage! Thames Water is also powerless. However, Henry thought of a way. People have to eat, drink, and lazar, right, isn't the sewage in the toilet sewage?

Henry thought of a previous life when Bill Gates and a number of non-profit organizations developed a device to turn toilet waste into drinking water. Henry also saw Bill Gates fill a glass of water on the video, then take a sip, then nodded, gave a thumbs up and praised, "Ouch, it tastes good!"

Although the sewage from the toilet is dirty, is the sewage from the sewer or river clean? After the industrial sewage is discharged into the river, it is not only dirty, but also highly toxic, but after being treated by sewage technology, it is just as good to drink!

It's just that the Africans like to defecate casually and don't pay attention to hygiene at all. The promotion of toilet sewage purification facilities also requires the construction of a large number of toilet public infrastructure. The investment is huge and not very cost-effective. As a result, such devices can only be rolled out on a small scale in Africa. But even so, it can solve the problem of drinking water a lot.

Since toilet sewage purification devices are temporarily unpopular, air water generators are undoubtedly a good choice. In a previous life, an Italian designer was concerned about the lack of drinking water for Africans and decided to find a cheap and viable solution to help people in these areas. After two years of development, he designed the 9-metre-tall water tower that looks like a vase from afar, providing 114 litres of safe drinking water per day to remote villages.

The Warka water tower is a simple, low-cost (US$500) water tower with a large amount of water, and its mechanism consists of two parts: an outer shell, which can be made of bamboo, which plays a fixed role, and an internal "mesh" made of nylon and polypropylene, which collects the water droplets formed on the surface. When the air condenses, the water droplets roll into the container at the bottom of the tower. The water collected in the container is then piped to the households.

The Warka water tower is so easy to make, and the use of bamboo and plastic makes it feel shoddy.

Henry felt that if he were to develop a water tower, he could make improvements on that basis so that the tower could collect more water. At that time, as soon as the "water-making artifact" comes out, it will be a blessing star for water-scarce areas in the world!

Of course, no matter how awesome the water-making artifact is, the water vapor content of the air is limited. Cities have large populations and large industrial water consumption, and water towers alone are not enough.

Only desalination can provide water on a large scale!

Sewage purification can be done by Thames Water, but the "Air Water Tower" has not yet been studied by a large company, and Henry can only recruit people to develop it himself. As for the desalination companies, there are some in the world, so according to Henry's temperament, it is natural to directly acquire several desalination companies.
