Tuvalu's approach has made the producer particularly angry.

However, for the protection of cross-border patents, it must be done in accordance with the laws of the country where they are located.

Although the industry standard developed by Tuvalu has not been in place for a long time, it does not conflict with other patents registered in the country, so it is in line with international practice.

Although this criterion is only valid in Tuvalu, it effectively prevents the registration of other similar patent applications.

In a country that is already on the verge of submerging its entire territory by the sea, no one would have thought of registering a patent before that.

Because no one would have imagined that such a huge demand market would arise here.

A small country would never have thought that it would develop a highly targeted industry standard for a specific industry, because its market capacity determines that it does not have such a big influence.

If you buy more than a dozen elevators all over the country, but you set such an industry standard, it can only become a joke, and those manufacturers don't even bother to pay attention to you.

But if you throw out a contract for the purchase of thousands of elevators, and take this standard as a necessary condition, it is worth paying attention to related industries.

You must know that Boeing built a new production plant for it in order to order 25 Boeing 747s.

The purchase order of thousands of elevators may give birth to a new elevator manufacturer.

Even if you get an order and carry out OEM production, you will have enough profit margins.

Who cares how much the so-called standards set by that small country in the bottom few countries in terms of land area may have an impact on the whole world in the future.

The establishment of connection standards between elevator components has made the maintenance of any elevator in Huaxia and Tuvalu District easier and more efficient.

More often than not, maintenance personnel only need to replace the corresponding functional modules to solve the vast majority of faults.

As the size of the urban units in Huaxia and Tuvalu is the same, there are many similarities in the social management model.

Therefore, the solid wood garbage cans produced by Huaxia also appeared in the pedestrian corridors of Tuvalu.

However, due to the complexity of the population of the Special Administrative Region of Tuvalu, there are also many people from other countries who come to visit for tourism and retirement.

Therefore, the lid of those garbage cans is pasted with eye-catching paper stickers, and the type of garbage that should be put in the corresponding garbage cans is indicated in the form of pictures and words.

However, in the special area of Tuvalu, there are no metal recycling and processing plants and recycled plastic processing plants, so these recyclable garbage such as metals and plastics will be transferred to another world for further processing when they reach a certain scale.

The grain, vegetables and various meat products produced by Huaxia have also been converted into current assets through the Tuvalu Special District, and used to purchase other production and construction materials needed by Huaxia.

The materials of the two worlds, under the effect of shared space, have achieved a benign interaction.

Relying on the real world, it took less than four years to transform the previously inaccessible Yunmengze into a land of fish and rice, which has to be said to be a miracle created by modern science and technology.

The successful transformation of Yunmengze waters has given Wei Minsheng a lot of inspiration.

Because in the real world, in the south of the colorful clouds, there is a place called Dianchi Lake.

Once upon a time, Dianchi Lake was known as a radius of 800 miles, with beautiful scenery and a long history, and had the reputation of the pearl of the plateau.

In the 60s of the last century, the water quality of Dianchi Lake, whether it is a sea of grass or an open sea, is class II.

In the 70s, the water quality was reduced to three categories.

In the 80s, the water quality of the sea of grass and the open sea were five and four respectively.

In the 90s of the last century, the water quality of Dianchi Lake deteriorated further, and the water quality exceeded five categories.

In just 30 years, the water quality of Dianchi Lake has dropped by three grades.

Perhaps, this water quality classification method is not intuitive for everyone to understand, so we can use another way to tell you the changes in the water quality of Dianchi Lake in the past 30 years.

In the 50s, the transparency of the grass sea could reach 2 meters, and the open sea was about 1 meter, and in some places it was even crystal clear.

In the 80s, the transparency of the grass sea was only 0.40~0.60 meters, and the open sea was 0.65~0.75 meters.

The worst in the 90s, the transparency of the sea of grass was only 0.25 meters, and the transparency of the open sea was only 0.41 meters.

The serious eutrophication of the water body has caused a sudden proliferation of plankton, which has seriously damaged the ecological balance of the Dianchi Lake waters.

At the height of the green algae outbreak, even the fish could not survive, so they had to struggle in the stinking water like green paint, and then die in despair.

The fish who want to fight for their lives with the sky, between the ups and downs, can only see half of the figure, which shows how bad the water quality of Dianchi Lake is.

In 2006, a well-known domestic water environment pollution control expert said: "If there are six or seven inferior standards, Dianchi Lake is."

In order to control the water pollution problem of Dianchi Lake, the local government has made continuous investment for more than 20 years, spending tens of billions of yuan, but with little effect.

Up to now, the water quality of the river flowing into Dianchi Lake has only been maintained at about three categories.

In order to solve the problem of eutrophication of the Dianchi Lake water, some experts have even proposed to use another invasive species, water hyacinth, to absorb nutrients from the Dianchi water body to reverse the deteriorating water quality.

But after years of experimentation, it is a drop in the bucket in the face of huge pollution sources and Dianchi Lake, which has almost completely lost its ability to purify itself.

The average depth of the water in Dianchi Lake is only five meters, the deepest depth is only eight meters, and the depth of the sea of grass is only one meter.

Due to the wide water area, the shallow water level, and the serious eutrophication of the water body, the energy of sunlight is almost absorbed by the surface of the water body, resulting in an increase in the surface temperature of the water body and a large amount of water evaporation.

However, the upstream supplementary water source is obviously unable to achieve the balance of natural replenishment and discharge of the water body.

Therefore, the water area of Dianchi Lake has been reduced again and again, and the current water area is less than 300 square kilometers, which is nearly 30% smaller than that of the Tang and Song dynasties.

In order to achieve the purpose of natural replenishment of the water body and let it resume self-purification, the only way to increase the depth of the water body and enhance the transparency of the water body is to enhance it.

The same glass of water, poured in a bowl and on a plate, has a different evaporation rate, because the evaporation rate of water is determined by the area it is in contact with the air.

The amount of water in Dianchi Lake is certain, in order to reduce the contact area between the water body and the air, the most direct way is to increase the depth of the water in Dianchi Lake.

The purpose of enhancing the transparency of the water body is to allow the energy of sunlight to cover a deeper area.

With the same heat, heating only the surface of the water and heating a body of water more than a meter, the result is completely different.

Because the lower the temperature, the slower the water evaporates.

However, in the face of such a huge body of water as Dianchi Lake, it is almost impossible to increase its transparency in the short term.

Therefore, reducing the area of water in contact with air is the only feasible way.
