In addition to establishing friendly relations, the purpose of visiting the city is to learn from experience. The country's foundation is weak, and it is necessary to learn more from the experience of other cities. And they also have activities in the country, and they are invited to visit the city and formulate investment strategies or construction plans.

Although this is a matter for the government, the government listens to the queen, so it indirectly becomes a matter for the royal family.

The government is not rich and has limited financial resources and capabilities, and they know that the royal family is the largest investor in the country, and the future prosperity is in the hands of the royal family, so they are very cooperative to let go of the power.

In late November, Joanna and Anfeng visited the vineyards of the Olbia region in the north. There are many grape producing areas in Sardinia, but the planting area is not large, mainly commercialized, and it is easily affected by market fluctuations and cannot precipitate culture.

An Feng, who has run vineyards, knows that quality is one thing, and history plays a key role – and history is mostly born of love. Wine brands must have been unknown in the early days, and without the persistence of love, vineyards can easily change hands, and the atmosphere of commercialization is strong.

To encourage a handful of old brands, the queen visited their winery.

The small number of vineyard owners in the north of Olbia are mostly locals, because this is their hometown, and the vineyard management has been passed down from generation to generation, although the results are not very good, but they are very determined, and the steadfastness also ushered in the visit specially arranged by the queen, and even stayed for an extra day.

The local population loved the Queen, and she was able to come and visit and let them prepare a week in advance, trying to show the interesting side of the wine industry without being boring. Then they were pleasantly surprised to find that the Queen and the Prince were clearly connoisseurs.

During the visit. An Feng revealed that they used to operate vineyards in California, and the name of Ann's Winery is more popular in North America, but the reputation in other regions is very average, and it is normal that I haven't heard of it here, but his professionalism makes the vineyard owner nod his head, and he is really attentive.

The Queen and her entourage visited four wineries. Receiving a high-level warm reception, she also considered some options to help promote the marketing of the traditional wine industry, hoping to increase the influence of the tourist city through guò, promote the consumption of alcohol, and thus enhance the influence of the wine industry.

When leaving the vineyard in the evening and returning to Olbia, An Feng asked in the car: "Are you concerned about the development of tourism in the northern region?" ”

Joanna said: "Don't you think that every change in every aspect is conducive to improving the overall impact? ”

"That's right." An Feng said.

A country's influence is based on many aspects. There are also prosperity in a few fields, but they can only be good rather than outstanding, such as the all-round development of the United States, which affects the whole world, and it is undeniable that the world is full of American movies, American music and American culture, and there are also American fleets adrift on the oceans, and there are notorious American GIs on land. There are also US satellites overhead......

Joanna looked out the window at the lush vineyards: "When I feel the warmth and joy of the local people, I am also happy from the bottom of my heart. I found myself slowly falling in love with this land that wasn't too rich and really hoped it would have a good future. ”

"This is the expression of a good king." An Feng applauded, "Don't worry, I will help you achieve it." ”

Joanna smiled, "I'm sure you can do it." ”

Overnight stay in Porto Cervo, a well-known tourist attraction with a well-developed service industry. The nearby city of Olbia is also an important port for Italian entry into Sardinia, and is a region with a developed tourist economy.

An Feng thought that this was a tourist city, because of the insipid character of the locals. Tourism is not overdeveloped, but since there are tourists, there will definitely be a demand for consumption, and the wine that Westerners love is indispensable, and it is more famous, and it can also stimulate consumption.

But how to improve fame?

It is certainly not enough to rely on the locals alone, they are content with the status quo, live a leisurely life every day, and the outside world has a lot of impression of the local area is sun and beaches, if you can have an attractive gimmick, it is completely different from other cities...... But it is different to be able to think and be able to do it.

The next day, the convoy went south to Olbia, which is more than 20 kilometers away, it is a port city, the surrounding land is relatively flat, in addition to tourism, there is also the development of some agriculture, from some bold ideas in his heart, An Feng also specially arranged to go to the sea and the place with flat land to inspect.

When she returned, Joanna asked him why.

An Feng said: "I have a very bold idea that will shock the world. ”

"What is it?" Joanna sat on the edge of the bed, his every bold idea was always amazing, and she was looking forward to it.

"Didn't you say you wanted to increase your influence?" An Feng said.

"Yes." She nodded.

"Olbia is probably a good place, I've checked, the local business atmosphere is good, it has a big port, the view of the coast is beautiful, there are flat lands along the coast, guess what I came up with?" An Feng looked at Joanna, "Give me a hint, superconductor!" ”

"Superconductors?" Joanna still couldn't connect all the keywords.

"Superconducting magnetic levitation!" An Feng didn't have an appetite for long, "I told you last time that room-temperature superconductors can be industrially synthesized under the condition of high technology and large consumption, right?" I'm going to pick a place with the best scenery, dig up a piece of land, reinforce it with reinforced concrete, and then install a room-temperature superconductor, and then increase the strength of the magnetic field on the ground, and in the room-temperature superconducting state, the land will be suspended......"

"You mean the Hanging Gardens?" Joanna suddenly understood.

"That's right!" An Feng was triumphant, pacing around the room with his hands behind his back, "Great idea, right?" ”

Joanna also knows that the superconducting state will have special properties, in addition to the use of electricity, its levitation capacity is also very strong, so that a two-ton car can levitate, the superconductor required is very small, because its lifting power is very large.

If the coveted room-temperature superconductor could be made, the sky garden would become a reality.

According to the Meissner effect, when the earth's surface magnetic field is enhanced, the superconductor will repel the magnetic field, that is, the stronger the surface magnetic field, the higher its levitation height, and the room temperature superconductor is obviously perfect. The suspended hanging garden, which is more than 20 meters above the ground, is definitely a modern marvel.

But she was sober: "How much land do you want to levitate?" ”

An Feng thought for a while: "A commercial plaza, about two hundred meters long." ”

"How much do you need for superconductors?" Joanna asked.

"Not a few." An Feng paused, "This is also a tricky problem, you have to calculate the empty weight and the maximum load weight, but it's okay to be overweight." It only reduces the height of superconducting levitation and does not collapse with a bang. You can even change the strength of the earth's surface magnetic field, and it can rise and fall like a lifting platform! ”

"How much is it expected to cost?" Joanna asked.

"According to the current cost of synthetic room-temperature superconductors, it is estimated that about 10 billion will be needed."

"That's fine." Joanna said that 10 billion to create miracles is also acceptable.

An Feng looked at her: "It doesn't have to be a room-temperature superconductor, high-temperature superconductivity is also fine, and the temperature is close to above zero." There is no need to use refrigerant, simply install a few refrigeration equipment, like a refrigerator, and keep it below zero at all times, so that the cost will be reduced a lot. ”

Joanna has a practical question: "What do you think about safety?" ”

"Take a combination scheme, one part high-temperature superconductivity and one part room-temperature superconductivity - at a minimum, if only room-temperature superconductors operate. It also keeps the suspended islands one meter above the surface, and high-temperature superconductivity helps to increase the height of the levitation. How is it? ”

"If you can do it, it's a miracle." Joanna was sure.

"I think so." An Feng said modestly.

After the inspection of the Olbia area, he returned to Cagliari and went to work on superconductors.

Ann's Industries is currently his main office location, with some employees from the United States. But it's more about the machine qì people - the machine qì people only represent two characters, either Eve or Hal , and artificial intelligence is indeed much stricter than humans in the matter of split personalities.

He and Hal discussed the mass production of room-temperature superconductors, as well as the hanging gardens he envisioned.

Hal thought about it and replied, "It takes time for room-temperature superconductors to be mass-produced. As for your hypothetical hanging garden, Eve has calculated for you, that it is very likely to be stored in a very high way, provided that the whole piece of land suspended is strong enough. ”

An Feng looked at Eve, it was only a few minutes, but he didn't expect her to be finished.

Eve, who has recently learned a lot about architecture, said: "The suspended land can be reinforced with concrete and steel to ensure the stability of the base, and the upper layer retains the natural land, and if you want to plant greenery, it is no problem, the green effect will regulate the environment." ”

"What about security concerns?" An Feng asked.

"Except for being attacked by Yan zhòng, it will be very stable, even if the artificial magnetic field equipment on the ground is destroyed, the earth's magnetic field can keep the land suspended and will not fall to the ground, and the existence of superconductors at room temperature means that the superconductivity phenomenon will be constant."

The result of the discussion with them is that there is a high probability that it will be realized.

Then comes the problem of cost and materials, the cost of Anfeng can slowly save money, but the materials are not easy to find.

HAAR expects to invest seven billion euros – in terms of their technology. For other countries, 70 billion may not be able to do it, because this includes materials and technology - the technology world is the only one, and other countries are still struggling with high-temperature superconductors, not to mention more profound.

In terms of the development of industrial technology, Hal has been expanded from one generation to four generations, and in some respects it is hundreds of years ahead of the earth, and the technological gap cannot be bridged by simple imitation. As a result, An Feng thought that the sky garden would be unique for a long time.

Using technology to create miracles, he was moved.

With this gimmick, the city will become a must-see tourist attraction, and in addition to the sunny beaches, visitors will be able to take to the skies to experience the legendary Hanging Gardens of Babylon in the future. The design of the sky garden can be exaggerated, and there are absolutely prospects for transparent corridors and the like.

An Feng spent some time discussing with Joanna, and they made a plan for mass production of superconductors, purchase of land, and renovation of land, which could take years to complete according to the schedule and financial calculations, and it would be faster to join the machine qì human link, but at the moment the machine qì sappers are very busy.

Make it the main plan, and focus on it when the important things are completed. (To be continued......)
