Downing was so addicted to building the Great Wall that he wanted to build a Great Wall in North America. Because the Mexican Civil War was raging, a large number of Mexicans illegally crossed the U.S.-Mexico border, and recently Mexico's French puppet emperor Maximilian was defeated by the native army and executed. The current leader of Mexico, Juárez, is a lawyer and seems to be quite talented, but Tangning is not optimistic about Mexico's long-term development, so the Confederate States of America built the Great Wall with him.

The Confederate governments were still discussing, and Downing couldn't wait to design the Great Wall of North America. This is all because recently he suddenly had a great idea, in addition to the wheelbarrow brick truck transportation scheme, he also came up with a great plan to reduce the production of bricks to almost free.

The loess of the loess giant bricks does not cost money, but it requires a lot of energy, cement and curing agent. Downing's latest idea is to do all of this, take the raw materials from the endless desert, sift them through a simple and rough way, blow the dust away, leaving behind silica-based sand grains, which are also the main material of glass, and then use dozens of large lenses to gather the fierce desert sunlight on the sand grains, making them vitrify at high temperatures.

Molten quartz flows through a calculated mold with round holes, and gravity condenses it into a sharp glass cone. When these glass cones are turned upside down, they are a huge brick with a side of one meter, but one side is covered with glass cones. It is about the same size as the Great Wall of Sand, the width of four bricks, and the glass spikes four meters wide and one meter high are enough to deter illegal border crossers. The amount of work is ten times smaller than that of the Great Wall of Sand Control, so the combination of 1,200 brick-moving wheelbarrows and 20 cranes can build the Great Wall at a speed of 10 kilometers per day.

The most powerful point of the Spike Great Wall is that the bricks are almost free, only the cost of 1,200 automated wheelbarrows, this kind of high-tech can be sky-high for others, but for their own team, that is, the cost of tens of thousands of pounds, the focus is on the salary of the 20 cranes, about 100 operators, about 40,000 pounds in total. The 3,169-kilometre U.S.-Mexico border is about a year's worth of man-hours, and £100,000 is enough to complete the world's unrivaled glass spiked Great Wall. Tsk, it's a good deal to think about.

The price increase of 50,000 pounds is exactly the level of an ironclad ship, and it can actually build a Great Wall? The Americans, quite incomprehensible, but confident in the technology of the great gods, decided to build this Great Wall. The U.S.-Mexico border is bordered by California, Arizona, New Mexico and Texas, and California has only 200 kilometers of border, so most of the £150,000 falls on the Confederate States of America. For Downing, it's just a little toy for him.

Obviously, this technique of obtaining building materials indefinitely in the desert was quite useful, and when it was used to make cheap buildings such as "Chief's House" and "Eggshell Building", it almost wiped out the bricks and tiles that were the largest construction cost of the house. Half of the material of the Great Wall of sand control can be replaced by glass bricks, which can save nearly half of the material money.

Both the Trans-Canada Highway and the Australian National Highway can use these cheap bricks to build guardrails that are half a meter wide and two meters high to ensure safe driving on highway sections. The only concern is that large-scale use could affect wildlife migration routes. Therefore, after studying the ecological impact, the high-speed section and the low-speed section were specially planned to achieve the purpose of achieving the best of both worlds.

As the richest man in the world, Downing himself does not like extravagance and waste, he thinks it is too rustic. Sissi was particularly envious of the Palace of Versailles, where Eugénie lived, and the Schönbrunn Palace in Vienna, where her sister Helen lived, and she felt that her husband could build more than these two luxurious palaces with a small amount of money. She is particularly fond of large gardens, the largest of which are at the Palace of Versailles, with more than 100 hectares, on par with the mechanized farms of the United States.

On this day, while the family was having dinner, Downing said to Princess Sissi, "I have decided to build a palace that is larger than the Palace of Versailles." ”

While Sissi and little Irene were rejoicing, Downing said, "But my garden is going to be built in Africa." ”

Sissi was puzzled: "Why was it built in Africa?" It's hot and arid, isn't it? ”

Tang Ning smiled and said, "Don't you like gardens?" Hey, what is 100 hectares? It's only one square kilometer. I like to be greedy, and our garden should be hundreds of square kilometers, hundreds of times the size of Versailles! ”

Although Sissi likes luxury and luxury, she is not without concept, these hundreds of square kilometers of gardens are not a joke, it is too ...... It's too big, although I don't know how much it costs to maintain the world's largest garden at the Palace of Versailles, it is estimated that tens of thousands of pounds will not be able to run away, if it is hundreds of times larger than Versailles, wouldn't it cost millions, or even tens of millions of pounds? The British Royal Navy's military expenditure is just over 10 million pounds a year......

Sissi couldn't help but giggle when she was making up the scene of people fainting after knowing that a certain local tyrant used money comparable to that of the British Navy to maintain the garden.

Tang Ning said: "What are you laughing at?" Don't believe me? It's true, and besides, I don't have to spend a penny on this garden. ”

Sissi suddenly realized: "I knew you must have some abnormal thoughts!" Where did you get a free garden of hundreds of square kilometers? ”

Downing explained with a smile: "Recently, botanists from the British Museum claimed to have discovered a natural wonder in South Africa, a desert called Namaquaran, which has a rainy season of six inches of rain in August and September, and these two months of rainy season are terrible, and the herbaceous plants grow like crazy, and then bloom, and finally spread all over the mountains, hundreds of square kilometers in size, and all the flowers that are not found anywhere else on earth. This desert is rich in iron and manganese, so the flowers of this natural garden are so gorgeous that they are not only larger than any artificial garden, but also far superior in quality to Versailles. Stupid humans are no match for gardening. I'll ask people to bring the photos, and you can see it, it's beautiful! ”

Downing sent a voice telegram to his assistant in the office of the President of the Federation, asking him to send the photo to the Marquis's Palace through the Guò Wind Bird Network, which was only a matter of minutes. When it comes to the German title, there is no longer a political status in the actual sense, but the monarchs of the original states still retain this tradition, and Tang Ninggui is the founder and chairman of the Confederation, and the title still stays in the position of the marquis. Liebig and other old friends in Munich like to call him Hou Ye, full of banter.

When the mother and daughter saw the beautiful photos of the desert flowers, they were both shocked by this magical land, no wonder Downing said that this garden was a hundred times stronger than Versailles. It's a pity that no matter how big the beautiful photo is, it is only as big as A4 paper, and it is definitely not as big as witnessing the boundless sea of flowers to enjoy.

Little Irene said, "Is Daddy going to take us here to play?" That's great! ”

Tang Ning smiled and said, "Isn't it just to play? I really want to build a palace, so I'll build a palace centered on the Namaqua Orchid Sea. Unfortunately, there is only two months of rainy season every year, and it is usually the same as a normal desert, so I have to renovate it, and I have already thought of a plan. I only thought of it recently, because I had already mastered a technique in the real yàn that could reduce the cost of construction to an incredibly low level. Moreover, this kind of building material, which is almost free of money, is still vitrified, which can be used as an excellent water channel.

What does it mean to be in the middle of a desert? It's a lifeline. In the western part of the Namaqualan Desert there is a port of Nolos, from which my aqueduct would start and pass through the town of Springbok, where copper is dug, to the heart of the desert, which is also the center of the sea of flowers, about 200 kilometers. In order to carry water that far, it is necessary to build towering water towers by the sea, and use the potential energy of water to distribute them throughout the desert lifeline.

This huge water tower is 100 meters high, and in order to get the water to that height, I don't use a pump, but use solar energy to heat the seawater at the bottom so that it evaporates to the top in the form of water vapor, which is also a condensing tower. The water-desalinated tower, which contains a huge amount of potential energy, will flow rapidly along the glass canal. There is a small outlet every 100 meters, and where there is water, plants grow, so there will be 2,000 small gardens along the 200 kilometers, and wildlife will also be attracted.

I'm looking forward to the 2,000 little gardens or the 2,000 safaris, with grasshoppers, bees, butterflies, beetles, violets, geraniums, sunflowers, pine chrysanthemums, ostriches, sandgrouses, mongooses, moles...... It's fun to see a scene every 100 meters along the flat sightseeing line above the glass canal! ”

Sissi listened fascinated and said with a smile: "There are only 1,400 fountains in the Palace of Versailles, and you have 2,000 fountains, and each fountain is surrounded by wild flowers, insects, and animals, so it's fun to think about it." However, with so many fountains, they have dried up by the time they reach the central garden in the heart of the desert. ”

Downing: "Uh...... When it is sprayed in the air, it vaporizes a lot, which is too wasteful...... However, it depends on the situation, of course, to ensure the supply of the central garden, it is really not possible to open a special line, but it is only 200 kilometers, and the glass material I have is! These glasses are actually like sunglasses because they contain a lot of impurities. In order not to block the migration of wild animals, the height of the pipe does not exceed one meter. (http：/／）。

Small animals like mongooses do not migrate, and migrating animals can jump over a meter of pipe, such as Springbok Town's mascot Springbok, which can run up to 100 kilometers per hour and easily cross 4 meters away. There are elephants living in the desert, not to mention them, elephants are very smart, I think they will stay on the edge of the garden all day long, and they will not be willing to leave, maybe our little garden will become an elephant zoo......"

Sissi still doesn't quite understand: "Is the material of this 200-kilometer pipeline really not expensive?" Why? ”

Tang Ning: "Of course, because all the materials are taken from the desert itself, and the heat provided by the sun can be used to heat the sand into glass, and to make the right reusable molds, I can make any kind of brick I want, including the outer square and the inner round canal." Even they can be welded like steel between them, and there is a small groove of one centimeter between these pipes, which is filled with molten glass of polymerized solar energy, and you can't quite tell that there is a weld! "In fact, it is a piece of molten glass that binds two pipes together every 5 meters, and after cooling, it does not leak. Beechcraft Tip: How to quickly search for the books you're looking for
