The most expensive thing about the arteries is not the poles, but the windmills. To this end, Downing designed "mini-castles" for these windmills, which generate electricity every 50 kilometers. This will be the first time in history that artificial stone will be used for the castle, and the factory in Beijing will manufacture the castle components according to the design plan, transport them to the laying site in a large airship, and assemble them.

The so-called castle is actually just a pillar supporting the H-shaped windmill, the main body is square, the bottom is thick and the top is thin, in order to save stone, the top is very thin. Interestingly, the bulky bottom has protruding balls at the corners, and the highlight of this design is that each of the four balls can be supported by fire from two adjacent balls. The scenario of an ordinary bunker where the enemy who is rushed closer calmly places the ** bag will not appear.

Artificial stone is a material where crushed stone is held together with a strong binder, which is stronger than natural stone. The principle of windshield is that there is a thin layer of adhesive between two pieces of glass, and this thin layer can make the glass still stick firmly when it is broken and not burst around. In particular, the castle material on the ground floor is made of reinforced stone, and guerrillas who don't know the truth often use ** to deal with the bottom, and they will find that this mini fortress will not be destroyed lightly.

Artificial stone also has a great point, it has a pipe in the middle, and during the construction process, a steel cable is used to pass through the pipe, which firmly binds the stone together and makes up for the weak point of the connection. And all these complex processes are inexpensive because of large-scale factory production, a mini windmill castle fortress is equivalent to a two-story small building, with a usable area of 60 square meters on the ground floor and 45 square meters on the second floor, not counting the narrow lookout on the roof. The cost, including all the construction and logistics, is equivalent to that of an ordinary house.

The fortress is there, but what are the sanitary conditions? Its domestic garbage, sewage, metabolites are all placed in a fixed place, every once in a while there are cleaning vehicles to transport them away, most of the garbage is incinerated by professional blast furnaces, sewage is purified and discharged, metabolites have a special way to "return to nature", this will not be detailed. In short, life in the fortress is very clean.

The quality of life here is so good that every three days a "blimp postman" delivers food, drinks, and goods that they mail order by telegraph, which is better than many of Britain's remote mountain benefits. The water source can also be solved by the guò postman, however, there is a better solution in Downing.

Do you remember the magic performed by the two queens at the opening show of the "Snow Queen" at the Palace of Versailles? The "impurities" that stimulate the crystallization of supercooled water are also present in the process of water moving from gaseous to liquid state, which is called "cloud condensation nuclei". In a space where only gaseous water molecules and other gases exist, the interaction between water molecules is small, and a slight drop in temperature is not enough to make water molecules in a supersaturated environment condense into a liquid state.

Using this effect, it was possible to draw water "out of nothing" in the air, and after experiments, it was known that a large kite was put into 1. At an altitude of 5 kilometers, a square meter of water intake network can obtain 10 liters of water a day, which is the worst level, in some plateau areas, it can even reach the level of 160 to 300 liters, and then the 10 square meters of water collection net containing water hose can be raised to the sky, at least 100 liters of water can be obtained a day, enough for two people to take a bath every day, according to the establishment of 5 people in each windmill fortress in Tangning, at least one bath can be guaranteed every three days, in fact, it is impossible for people living in alpine areas to have such a vigorous bath.

On the second floor, there is a large water tank, bath water can also be used to flush toilets, and the bottom sewage pipe will discharge sewage away from the fortress. Bathing and flushing toilets are big users, and if you have no problem with both, you don't have to worry about drinking water at all.

Downing plans to recruit troops in Sweden, Denmark, Hokkaido, Tohoku, Canada, and other places to protect the Siberian artery, and the advertisement is impressively "Recruit soldiers in a mini-castle where you can take a hot bath every day!" "It details Downing's various technical solutions to solve the problems of the soldiers in the windmill fortress, even if you are not interested in being a mercenary, you will find it interesting to see.

This magic technique of taking water for small fortresses was soon discovered by entrepreneurs to have a huge application prospect, just flying a kite can get so much water, if you use a helium balloon to rise to a higher altitude, with thousands of square meters of water intake network to collect water, is not a day can get tens of thousands of liters of water? Of course, the inhabitants who used water in the sky were not the same as the soldiers of the fortress, and if they used 300 liters per person per day, the capacity of a large high-altitude water collector could theoretically support 100 people. This is already the level of a standard water tower, and what is even more wonderful is that this water collection method saves electricity bills, not only that, but the process of water tower discharge can even be used as a power source for power generation, which is not the integration of hydropower and electricity?

In the past, it was always said that hydropower generation was limited by geographical conditions, but now, the industrial gods have pointed out a way for mankind - artificial "rivers" to generate electricity, and they can freely choose the drop, and the flow can go down to 3,000 feet without pressure.

Downing said in the Telegraph that he would give up the patent for the technology because it would reduce the need to build dams that stop fish migration and affect speed, and the world could use it to make hydropower-integrated water towers based on this principle.

This power generation capacity is more interesting, 10 liters of water to 1. A drop gauge of 5 km, if 80% of the energy is converted into electricity, will reach 18. 5 kilowatts, this figure is very impressive, which means that as long as you learn to fly a kite, an American farmer family far away from the city can buy such a set of entry-level hydropower integration equipment, and hydropower will not have to worry.

If this set of equipment with extremely high hydropower efficiency is popularized, it is difficult for Tangning to imagine that thermal power plants can still be developed.

Inventors all over the world are in a race to see who can build the most market-accepted integrated water and electricity equipment. At this time, a scientist said: "Let's not forget how the great scientist Franklin proved that lightning is electricity, and high-altitude water intake equipment is in danger of being shocked!" "I poured cold water for everyone, yes, it seems that this product is not without shortcomings.

Damn, fortunately, someone reminded me that Tang Ning almost forgot to protect against lightning. It seems that this kind of equipment can't be done in every household, you must pay attention to safety, not far from the city, it's best not to get one yourself, 1. The 5-kilometre-high mine-channeling kite is no joke.

The most imaginative application is that a captain has built a small kite on a lifeboat that can hold up a 1 square metre net that not only supplies at least 10 litres of water per day, but also has enough electricity to cook and sail for the refugees on board! This kind of refugee life is really enjoyable, it is simply against the sky. People laugh at this brain hole application while wondering what is wrong with this scene.

It turned out that the captain had forgotten the weight of the kite's electrical system,1. A 5-kilometer hose (polyethylene) weighs 50 kilograms, a dew net with water droplets is 20 kilograms, and a large kite is at least 30 kilograms. Another 50 kilograms from the generator, and these 150 kilograms are equal to the weight of two people.

There is no problem in fetching water, but the weight and space of this large pile is probably not something that a lifeboat can bear. When sailing, under the influence of this pull, it will deviate from the course or even go in the opposite direction. A one-square-meter dew collector kite can provide about 770 watts of motor operation, and whether this motor engine can exceed the negative effects of its own weight and wind force will be the key to the viability of this conceptual lifeboat.

But the concept was interesting, and Downing decided to set up kite clubs in nine cities, including Beijing, Tokyo, Singapore, Kolkata, Munich, Milan, London, Port Windsor, and San Francisco, and bought large tracts of land to build empty kite parks specializing in small kite motors that could be used in lifeboats. The purpose wasn't to actually put it on a lifeboat, but it was a design competition.

Each city has a technical team, people all over the world can provide a design plan to the technical team, if the design plan can convince the technical team, the team will help the designer to make this kind of motor, and then participate in the kite motor competition, in case this design is industrialized, the designer can obtain a design patent, which can be sold to General Dynamics, which is responsible for this project, which is really not practical, at least Downing will treat these 9 parks as a public welfare project, and everyone can go to fly kites and have fun.

Vanderbilt started a kite club in New York and asked Downing to send a technical team to support and get support. Later, Charles Morgan also started a kite club in New Orleans. For some reason, Downing's partners in various countries were interested in investing in a kite club, Nobel had one in Stockholm, Hans Christian Andersen had one in Denmark, Xu Run had one in the French Concession in Shanghai, and Vale had one in Rio de Janeiro. Later, Tang Ning realized that everyone was just trying to find an excuse to make a big park. （http:／／.)。

Ordinary parks are sold by flowers and trees, and there must be no trees in the magical kite park, otherwise it is easy to entangle the kite, so it is a super wide square, and the lawn can be there.

There are so many technology enthusiasts all over the world, and finally a genius inventor has come up with a "leaky" kite, which is a normal kite during the take-off stage, and when it flies to 1. At an altitude of 5 kilometers, the "blinds" on the kite's body can be opened through the wires, and it can control the wind area of the kite, and it can be from large to small multiple gears, which proves to be the most effective design in real yàn, a kite electric bicycle can speed at 25 kilometers per hour. Don't underestimate these 25 kilometers, the speed of an ordinary train is only 50 kilometers per hour, and 25 kilometers is already 5 times that of walking. It's a pity that it's impossible for a normal bicycle to pull a kite, otherwise this means of transportation would have been very popular.

No, if a cyclist is off-road, driving in an environment where you can't see people for half an hour, wouldn't it be nice if there was such a kite electric engine...... At least it's possible.
