Silicon Valley

The moon has no water and no oxygen. Because the Moon's mass is too small, the resulting gravitational force is not strong enough to form an atmosphere. Therefore, there is a vacuum on the moon. Therefore, an environment suitable for earthlings to live in can only be created within a closed building.

Planet immigration, 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 transfer water, in addition to using the space shuttle, building a "space ladder" seems to be a good choice.

The concept of "Space Ladder" was proposed in 1970. In 1999, the Advanced Office of NASA's Marshall Center published the article "Sky Ladder: Advanced Infrastructure in Space", marking that the Sky Ladder will move from fantasy to reality! Dr. Brad Edwards of the Fairmont Institute for Science, known for his research on the ladder, wrote in the paper: "The ladder could enable the development of human history by leaps and bounds."

Once the "space ladder" is built, it can carry out transportation work around the clock, sending tourists and cargo into space, and greatly reducing transportation costs. Today, a rocket launch or a space shuttle costs about $20,000 per kilogram of payload, while a space elevator costs only $10 per kilogram of items, enabling a leap forward in space technology.

The structure of the space ladder mainly includes the base, the cable belt, and the elevator cabin.

The base can be chosen to be at the equator, so that it hangs the shortest distance from geosynchronous orbit. The elevator cabin is not difficult. The most difficult thing is the cable, because the cable has to hold the capsule, and the pulling force is the strongest. If the cable can't bear 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, because the tension that carbon nanotubes can withstand can reach the standard of carrying space elevators.

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

Since graphene has been developed by Henry in advance, and the technology of manufacturing graphene is the latest technology in 2015. Therefore, the manufacturing and development of graphene has greatly accelerated the development of current technology.

In the past life, the United States and Japan were most obsessed with the study of space ladders. In addition to NASA in the United States, the famous Google company is also conducting this research! As for Japan, they even invested $7.3 billion 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 first is almost equivalent to winning the ticket to colonize outer space. As long as you have a little ambition, you will not miss this opportunity! Little Japan is very ambitious, but his land is only the size of a palm, and of course he wants to colonize other places!

However, space ladders are not so easy to manufacture. Even with the strength of a super material company, there is no hope in a short time. The biggest difficulty is that current nanotechnology is not advanced enough to make proper carbon nanotubes out of graphene!

However, Henry is not in a hurry. Take your time, building a space ladder on Earth may not be successful in twenty or thirty years! But on the moon, it's much simpler. The gravitational force of the moon is very small, and the pulling force on the cable of the space ladder is also very small. It may take more than ten years to successfully manufacture the lunar space ladder.

In fact, it doesn't have to be that rush to make a space ladder. The current earth's water resources are extremely scarce, and there are many places where water is not even available. If Henry transferred the fresh water from the earth to the moon, the fresh water on the earth would be even more insufficient. Therefore, the first problem Henry has 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. When they were born, married and died, the water shortage was serious, which is evident.

Water scarcity is like a witch's claws, strangling the throats of many countries. And as the population increases and industrial water usage increases, water resources will only get more and more strained! 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 seawater desalination. In addition, the air also contains a lot of moisture, and the other is sewage purification.

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

Think of the oil-rich Middle East, where because of its desert location and large population, 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 would also consider buying a large piece of land in Africa, carry out "African Development", and build an independent kingdom!

...

Henry temporarily owns Thames Water, a company mainly engaged in sewage purification. But "a clever woman can't cook without rice", many countries don't even have sewage! Thames Water is also powerless. However, Henry thought of a way. People have to eat and drink, right? Is the sewage in the toilet not sewage?

Henry thought of his previous life. Bill Gates and some non-profit organizations had developed a device that turned toilet sewage into drinking water. Isn't this device awesome? Henry also saw Bill Gates fill a glass of water on the video, then took a sip, then nodded and praised with a thumbs up, "Ouch, it tastes good!"

Although the sewage in the toilet is dirty, is the sewage in the sewers or rivers clean? After 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 Africans like to urinate casually, and they don't pay attention to hygiene at all. The promotion of toilet sewage purification devices also requires the construction of a large number of toilet public infrastructure. The investment is huge and not 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 cannot be popularized for the time being, air water making devices are undoubtedly a good choice. In a previous life, an Italian designer felt the inconvenience of drinking water in Africa and decided to find a cheap and feasible solution to help people in these areas. After two years of deliberation, he designed a water tower called Warka, which is about 9 meters high and looks like a vase-shaped water tower from a distance, which can provide 114 liters of safe drinking water to remote villages every day.

The Warka water tower has simple technology, low cost ($500), and large water volume. Its mechanism mainly includes two parts: the outer shell and the inner plastic mesh. The outer shell can be made of bamboo for fixing; the inner part is made of nylon and polypropylene. The "mesh" is responsible for collecting the water droplets that form on the surface. When the air condenses, the water droplets will roll obediently into the container at the bottom of the water tower. The water collected in the container is then piped to thousands of households.

The Warka water tower is so easy to make, and it just uses bamboo and plastic to make it feel like a shoddy one.

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

Of course, no matter how powerful the water-making artifact is, the moisture content of the air is limited. With a large urban population and large industrial water consumption, water towers alone are not enough.

Only desalination can provide water on a large scale!

There is Thames Water Company for sewage purification, but there is no large company to conduct research on the "air water tower", Henry can only recruit people to develop it by himself. And desalination companies exist in the world, so, according to Henry's temperament, it is natural to directly acquire several desalination companies.
