The border wall on the U.S.-Mexico border is a very controversial thing, and opponents have a strong reason, that is, this is too expensive for taxpayers' money, I don't know why, Ju Chen casually mentioned that if he used the method of building a metal mesh that his graduate team accidentally discovered when developing the C2 energy storage device, the U.S.-Mexico border wall could be built at a price of $1 billion, and this figure would cost $20 billion from experts invited by the mainstream media.

His words really sparked a lot of comments, both positive and negative.

Juchen himself doesn't care about the policy itself, but he is responsible for what he says, so he really asked the team to seriously study a plan, using the random aperiodic brick group method + kink theory to create an extremely complex steel cable network, which can achieve the purpose of being difficult to destroy.

Even if you are a top student in topology of the Department of Mathematics, you have to carefully investigate for a period of time to judge the weakness of a group of steel cable nets, and this set of steel cable nets is up to 1 meter thick and has 10 to 100 combinations, so it is difficult for ordinary stowaways to overcome, and the steel cable material used for cable-stayed bridges is of course difficult to destroy.

After the results of this research came out, it sparked a heated discussion in the civil engineering industry, and the official accounts of the White House invited Juchen to build a sample wall, which triggered a wave of forwards and comments from the government and the public.

Originally, Juchen didn't plan to manage the White House, but in addition to the invitation on Twitter, they also officially sent out an invitation, and a student also said: "In the future, this kind of steel cable net can also be used to build prisons, so it has commercial value, and by the way, it is not a loss to develop a sample wall." ”

So, he asked the team to do something.

This technology is not only low-cost, but also surprisingly fast to build, and the current White House plans to build a wall on half of the 3,000-kilometer border in 10 years, at a cost of $33 billion.

The budget engineer participated in the construction of the steel cable sample wall, and after obtaining the actual data, the cost price was 3 billion US dollars, and the rate was 3 years, of which 2 billion US dollars were used to pay for equipment and personnel salaries. It seems to be very similar to the $1 billion cost that Ju Chen casually said, so much so that Juchen thinks that the budgeter is not making up the number.

The Border Guard sent someone to identify the model wall and gave a good evaluation, and the student in charge of the project was very excited, saying: "We can make money on this project, in order to advertise the prison project in the future." ”

Juchen laughed: "Why is it necessary to do such a hard advertisement? Our pricing is not determined by cost, but by looking at competitors, since the budget of the White House is 33 billion US dollars, we do not spend it for the president, I am afraid that it will make the local tyrant president unhappy, so our offer is also 33 billion US dollars, a penny is a lot, this is the best advertising." ”

The student was dumbfounded: "This ...... I'm afraid it's hard to win the bid, right?"

Ju Chen: "Such a controversial project, after it is built, it will be scolded, rather than being scolded for not making money, it is better to make a lot of money, just like when I received the endorsement of the tobacco company." Besides, while others spend 33 billion yuan in 10 years, which is only half of the border, we spend 3 years, and the time cost is not counted? Our plan is already six times better. I just didn't expect to build a wall that was six times better than others, so it's a good deal. The White House doesn't want to spend so much money? Okay, give 15 billion, I'll build half of it for you, save half of the money, it's still cost-effective. ”

As soon as the student heard this, he reported his offer to the White House, and sure enough, he was scolded by that side and came back in disgrace.

Although he was scolded by the White House, he couldn't help but be famous, and his 100-meter model wall was visited by people from all over the world every day, and it has become a unique scenery on the border.

There are also unbelievers who want to study the weaknesses of the wall, only to be defeated by the incomparably complex random non-periodic kinks, and throw in the towel in frustration, making the Tightrope Wall even more famous.

Spot welding, is a very mature automation technology in the industry, the three-dimensional steel cable mesh is linked by millions of welding joints, it is simply a copper wall, dense mesh and the more irregular and steep the design of the climb, but also makes climbing an unrealistic fantasy.

There is no need to completely excavate the earthwork in the underground part, and the tightened steel cable is equivalent to reinforcing the land, making it more difficult to break through in the mode of tunnel warfare.

All in all, in terms of cost, construction efficiency, and difficulty of destruction and breakthrough, the Juchen team's cable wall has completely outperformed eight opponents, which is amazing in engineering.

Concrete is poured in key areas for better results.

The special inverted design allows the top to have a 2-meter-wide "usable space" that is larger than the bottom one-meter wide, which can be used to develop border corridors, on which border guards can drive, and some sections can also be developed into tourist corridors.

Juchen joked: "It's okay to ask the Mexican government to pay for it, and in exchange, it may contract the land for tourism development to Mexicans." ”

Unexpectedly, the official account of the Mexican Government Tourism Agency actually came to ask "Can the project really make money?"

Some netizens commented: "This seems to be a question asked by a child to a teacher, the professor is really a teacher, and he is a university teacher." ”

Juchen continued to joke and replied: "This is equivalent to the Great Wall of the United States, as famous as the Great Wall of China, how much money can the Great Wall of China make, the Great Wall of the United States is at least not far behind, right?"

Badaling-Ming Tombs receives 16 million tourists a year!

If the Great Wall of the United States is fully developed, it will have at least 10 million, right? If each tourist spends $1,000, the overall income can reach $10 billion per year, how cost-effective this business is!

Then, the Mexican Tourism Board was actually moved.

Juchen's interaction with Mexico's tourism authority was hailed as a joke online and made headlines in the mainstream media.

A month has passed, and neither the White House nor the Mexican Tourism Board has ever written about it, but the great creation of the cable wall has not disappeared, because Ju Chen's whim tasked the team to design a second car after the M14, which is a serious family car, similar to the positioning of the Model-S, with a shocking subversive design, completely replacing fuel with a three-dimensional clockwork energy storage device.

This is not the key to the disruption, the point is that the three-dimensional mainspring is not only placed on the bottom of the car, but also throughout most of the body, except for the windows, which makes the specification of 50 kilometers at a time to 100 kilometers.

At the same time, the three-dimensional mainspring has its own properties of a cable wall, which partially replaces the body structure, so that the increased weight of 900 kg is not noticeable, because the frame is simplified. Looking at the past from the outside, the whole vehicle is transparent, originally everyone thought that this was to let everyone see the internal renderings, but I didn't expect this to be the final rendering!

Through the transparent aluminum body, you can see the whole process of the three-dimensional spring from tightening to relaxation, various geometric patterns, beautiful and incomparable, it is really a model of man-made objects, not much better than God's creation.

Because there is already a three-dimensional mainspring that acts as a cable wall, the transparent aluminum does not need to be so thick, as long as it is structurally used as a roof beam. The steel cable wall is so strong, the crash test is definitely far better than that of friends, and it can also prevent the battery from exploding, because the mainspring cannot explode, and will only release mechanical energy in a small limited space instantly, which is impossible to cause damage to the owner.

100 kilometers is not a long battery life, and the reserved range extender excuse can easily access a large-capacity fluid battery, which is specially used for winding up and charging in seconds.

The Cable Wall continues the legend of its unique creation and design, and the car is named: A Clockwork Orange S100. S stands for Sedan, which is benchmarked against Model-S, and 100 stands for the energy density of the mainspring with a second charge life.

This incredible clockwork orange S100 is a shocking sensation, and its bizarre design is sung everywhere inside and outside the industry, and it is hailed as the most sci-fi car that can be launched.

Professor Juchen's reputation can almost compete with the sun and the moon, and the White House Border Wall Committee sent someone to ask: "Can it be cheaper?" The headquarters may cost you 3 billion yuan, and the government needs 33 billion yuan, right?"

Ju Chen's student: "30 billion is always wanted, and if the tourism function is contracted out, it can be reduced by half, and the Mexican Tourism Office may be willing to take over." ”
