The moon has no water and no oxygen. Because the mass of the moon is too small, the gravitational force generated is not enough to form the atmosphere. Therefore, there is a vacuum on the moon. Therefore, it is only possible to create an environment suitable for the living of the people of the earth in a closed building.

For planetary migration, water and oxygen are indispensable.

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

The concept of "Space Ladder" was put forward in 1970. In 1999, the Advanced Office of NASA's Marshall Center published the article "Ladder: Advanced Infrastructure in Space", which marked that Ladder would move from fantasy to reality! Dr. Brad Edwards of the Fairmont Institute of Science, who is known for studying ladders, wrote in the paper: "Ladders can make human history achieve leapfrog development."

Once the "Space Ladder" is completed, transportation can be carried out around the clock to send tourists and goods into space and greatly reduce transportation costs. Today, rocket launches or space shuttles cost about US$20,000 per kilogram of payload, while space ladders only cost US$10 per kilogram of items, which can promote the leapfrog development of space technology.

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

The base can be selected on the equator, so that the distance from the geosynchronous orbit is the shortest. The elevator warehouse is not difficult. The most difficult thing is the cable, because the cable has to pull the space capsule, and it bears the strongest pulling force. If the cable cannot withstand it, it will break. Therefore, the material problem of the cable is the biggest factor hindering the development of the space elevator. The most promising material is carbon nanotubes, because the tension that carbon nanotubes can withstand can reach the standard for carrying space elevators.

This "carbon nanotube" is nothing else, it is graphene! However, it is formed by curling graphene sheets, which can be divided into single-wall carbon nanotubes and multi-wall carbon nanotubes according to the number of graphene sheets.

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

In previous lives, the United States and Japan were most obsessed with the research of space ladders. In addition to NASA, the famous Google company is also conducting this research! As for Japan, they even invested 7.3 billion U.S. dollars to develop 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 is almost equivalent to winning the ticket to colonize outer space. If you have a little ambition, you won't let this opportunity go! Little Japan is ambitious, but his own land is only as big as a palm, and of course he wants to colonize other places!

However, the space ladder is not so easy to manufacture. Even with the strength of Super Materials, there is no hope in a short time. The biggest difficulty is that the current nanotechnology is not advanced enough to make suitable carbon nanotubes from graphene!

However, Henry is not in a hurry. Slowly, building a space ladder on the earth may not be successful in 20 or 30 years! But on the moon, it's much simpler. The moon’s gravitational pull is very small, and the tension on the cables of the space ladder is also very small. Perhaps it will be possible to successfully build a lunar space ladder in more than ten years.

In fact, it doesn’t have to be that rush to build a space ladder. The current earth's water resources are extremely scarce, and there are so many places where even water is not available. If Henry transferred the earth's fresh water to the moon, the earth's fresh water would be even more insufficient. Therefore, Henry's first problem to solve is the shortage of water resources on the earth!

In Huining, Gansu, China, it is said that people here only take three baths in their lives. This is evident in the severe water shortage at birth, marriage and death.

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

At present, the ocean area on the earth accounts for 70.8% of the total surface area, and the average depth of the ocean is about 3800m. Therefore, in addition to the freshwater resources that can be used directly, there is no doubt that the best way to obtain freshwater resources is desalination. In addition, the air also contains a lot of moisture, and the other is sewage purification.

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

Think of the oil-rich Middle East. Because of their deserts and large populations, fresh water is very scarce, even more precious than oil. Even if it is a barrel of water for a barrel of oil, they are willing!

If there is a "water-making artifact", perhaps at that time, Henry will also consider buying a large piece of land in Africa, carrying out the "African Development", and creating an independent kingdom!

...

Henry's name temporarily has the British Thames Water Company, which is a company mainly engaged in sewage purification. But "smart women can hardly cook without rice." Many countries don't even have sewage! Thames Water Company is also powerless. However, Henry thought of a way. People have to eat and drink, right? Isn’t the sewage in the toilet sewage?

Henry thought of his past life. Bill Gates and some non-profit organizations have developed a device that converts toilet sewage into drinking water. Is this device awesome? Henry also saw on the video that Bill Gates filled a glass of water, then took a sip, then nodded and praised with a thumbs up, "Oh, it tastes good!"

Although the sewage in the toilet is dirty, is the sewage in 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 it is treated by sewage technology, it is as good as drinking it!

It's just that African guys like to urinate and urinate casually and don't pay attention to hygiene at all. The promotion of toilet sewage purification devices also requires the construction of a large number of public toilets. The investment is huge and not very cost-effective. Therefore, this device can only be promoted in a small area in Africa. But even so, it can solve a lot of drinking water problems.

Since toilet sewage purification devices are temporarily not popular, then air fresheners are undoubtedly a good choice. In a previous life, an Italian designer felt the inconvenience of drinking water for African residents and decided to find a cheap and feasible solution to help people in these areas. After two years of brewing, he designed a water tower called Warka, which is about 9 meters high and looks like a vase-shaped water tower from a distance. It can provide 114 liters of safe drinking water to remote villages every day.

Warka water tower has simple technology, low cost ($500) and large water volume. Its mechanism mainly includes two parts: the outer shell and the internal plastic net~lightnovelpub.net~ The outer shell can be made of bamboo for fixing purposes; Nylon and polypropylene are made into "mesh", which is responsible for collecting the water droplets formed on the surface. When the air condenses, the water droplets will roll obediently into the container at the bottom of the water tower. Subsequently, the water collected in the container will be sent to thousands of households through pipelines.

The Warka water tower is so easy to make, and it's done with bamboo and plastic, it feels like a shoddy construction.

Henry felt that if he wanted to develop the water tower, he could make improvements on this basis so that the water tower could collect more water. By then, as soon as the "water-making artifact" comes out, it will be a blessing for water-scarce regions in the world!

Of course, no matter how awesome the water-making artifact is, the water vapor content in the air is limited. With large urban populations and large industrial water consumption, water towers alone are far from enough.

Only desalination can provide water on a large scale!

The sewage purification can be done by Thames Water Company, while the "Air Water Tower" has not yet been studied by a large company, and Henry can only hire people to research and develop it himself. There are desalination companies in the world. Therefore, according to Henry's nature, it is natural to directly acquire several desalination companies.
