Chapter 94 The Beating Sea of ​​Lanterns

Zhao Zhicheng is close to 40 years old. He has opened a small company and lived a good life. He has a petty style.Life is better, and there are more things to think about. The desertification of the world is getting more and more serious, and China is actually ranked first, which makes him feel stuck in his throat with some spare money.

Not everyone takes money so seriously, and when money accumulates to a certain amount, it loses its original meaning.Instead of letting the money go bad in his own hands, it is better to use it to do something more meaningful, so he thought of investing in the greening of the desert.

He found a lot of connections, and finally got his wish to get a piece of desert land for greening and transformation, but the reality is always cruel.He spent four or five years throwing in more than [-] yuan, but each time he got in exchange for dead plant seedlings.The repeated blows did not extinguish the hope in his heart. While working hard to make money and continue to raise funds, he checked the characteristics of various plants, foreign methods of transforming deserts, etc.

When he heard about the desert greening transformation organized by Kaitian Group, he immediately logged on to the website and applied for volunteers.For this landscaping renovation, he donated more than 5 RMB. Looking at the materials prepared by Kaitian Group in his hand, he was overwhelmed.

These materials are carefully prepared. They not only introduce the hazards of desertification, but also introduce the performance of new plants and the methods of desert greening transformation.If I could get such a comprehensive introduction as soon as possible, the hundreds of thousands I invested would not be wasted.

It got dark quickly, and although they didn't do anything on the first day, everyone had assigned tasks for the second day according to the group.As the leader of one of the teams, he was also issued a walkie-talkie so that he could listen to expert opinions and coordinate the entire landscaping renovation work.

As the sky darkened, the staff of Kaitian Group called the team leaders of each group together through the walkie-talkie.The team leader of each group, following the instructions of Kaitian Group staff, brought two or three people to the greening command office.

Zhao Zhicheng lined up with the members of his team and got today's dinner and lighting equipment from the staff.In the depths of the desert, there is no way to be picky about eating and drinking. Those who can participate in volunteers have long been prepared in their hearts.Looking at the beef jerky and steamed buns in his hands, Zhao Zhicheng couldn't help but sigh in his heart.

To be able to prepare such extravagant food for so many people in the depths of the desert, how much manpower and material resources does the Kaitian Group need to invest.Although the amount may be smaller, there is no way to control the fullness, at least it is much better than what I ate when I came to the desert.

For lighting at night, Kaitian Group also distributed lighting equipment by group. Looking at the lighting equipment in his hand, Zhao Zhicheng's eyes lit up.I have been in the business of electronic products for these years. If I guessed correctly, these lighting devices should all rely on new fuel cells to provide power.

On the way back to his team's tent, Zhao Zhicheng chatted with his team members while carefully checking the lighting equipment.Everyone is curious about this lighting device, which is an energy-efficient lighting device powered by hydrogen fuel cells.

As an environmentalist, Zhao Zhicheng, who runs an electronics business, has also learned about fuel cells.He recognized at a glance that it was a hydrogen fuel cell that powered the lighting equipment.It was just beginning to feel unbelievable, but after such a long period of observation, he had already confirmed his own judgment.

Through some information, he knew the basic principle of hydrogen fuel cell power generation, which is the reverse reaction of electrolyzing water, supplying hydrogen and oxygen to the cathode and anode respectively. After the hydrogen diffuses outward through the cathode and reacts with the electrolyte, electrons are released to reach the hydrogen through the external load. anode.

As early as the 19th century, in the novels of Jules Verne, the originator of French science fiction, visionaries predicted that society would one day be completely transformed by hydrogen-based energy.This lightweight gas, the most abundant element in the universe, can be made from water; it's surprisingly clean; and when it burns, it emits essentially fresh steam.Delivering unprecedented efficiency when fed into fuel cells that generate electricity, these electrochemical reactors can extract up to twice as much useful energy from the fuel as internal combustion engines.

About 70.00% of the combustion energy of traditional thermal power plants is consumed in huge equipment such as boilers and turbo generators, and the combustion consumes a lot of energy and emits a lot of harmful substances.The use of hydrogen fuel cells to generate electricity is to directly convert the chemical energy of the fuel into electrical energy without combustion, and the energy conversion rate can reach 60% to 80%. It also has less pollution and less noise, and the device can be large or small, which is very flexible.

I have known about hydrogen fuel cells for a long time, and know that it is much more environmentally friendly than traditional power generation methods.His only shortcoming is that the cost of production is too high, so it has not been used in practice. It is just that Kaitian Group can produce so many lighting equipment with hydrogen fuel cells at one time.

After dark, everyone sat around under the lighting equipment, eating hot and soft steamed buns and fresh beef jerky, while assigning tasks for the next day.After assigning tasks, everyone became interested in this special lighting equipment. If Zhao Zhicheng didn't dissuade them, some people even wanted to disassemble the lighting equipment for research.

Sometimes, people's curiosity will become very strong. Even ordinary people who do not study physics will always want to understand the principle of something new when they see it. Maybe this is also the driving force for human development.

Everyone gathered in front of the lighting equipment, listening to Zhao Zhicheng's explanation of what they learned about hydrogen fuel cells, they all lamented the strength of Kaitian Group's scientific research.

In recent years, I have always heard that developed countries such as Japan and the United States have successfully developed portable fuel cells, but no one has really seen it.Now the fuel cell researched by Kaitian Group is placed in front of their eyes, and these people are full of pride when they see the fuel cell developed by their own country.

Many people have learned about the benefits of fuel cells from the news, knowing that it can be more environmentally friendly and more convenient, but the fuel cell in front of them obviously uses hydrogen as fuel.

Hydrogen has high volatility and high energy, and is an energy carrier and fuel.The battery using hydrogen fuel will not emit harmful gases such as carbon monoxide and carbon dioxide after combustion, which is more environmentally friendly.

The calorific value of hydrogen combustion is high, and the heat of combustion per kilogram of hydrogen is about 3 times that of gasoline, 3.9 times that of alcohol, and 4.5 times that of coke.The product of hydrogen combustion is not harmful gases such as carbon dioxide, but water, which is the cleanest energy source in the world.

Hydrogen is rich in resources and can be produced from water, and water is the most abundant resource on earth, which represents a classic process of recycling and sustainable development of natural materials.

Hydrogen is the most common element in the universe. Hydrogen and its isotopes account for 80.00% of the total mass of the sun, and 70.00% of the mass of the universe is hydrogen.Liquid hydrogen can be used as rocket fuel, because the liquefaction temperature of hydrogen is minus 250 [-] degrees. If the pressure is increased to hundreds of atmospheres, liquid hydrogen can even become metallic hydrogen.

Everyone has known hydrogen for a long time, and heard that foreign countries are developing hydrogen fuel cells, but no one thought that Kaitian Group could already produce mature products.It's just that these people don't know that the fuel cell used in the lighting equipment this time is also a product that Kaitian Group has just successfully developed and is not mature enough.

Although these fuel cells are internationally advanced technologies, they are not satisfactory to Wang Zhen. The purpose of this desert greening renovation is to use these batteries for some testing work on the batteries.

Everyone was discussing, when they suddenly heard a distant folk song coming from outside, everyone walked out of the tent curiously to check who was singing.

It turns out that among the volunteers who participated in the desert greening transformation this time, in addition to the Han people, there are also many ethnic minorities who like to sing.When everyone felt the source of the singing, they saw that there were already many people sitting around with lighting equipment in front of them, and in the middle of the empty space, many compatriots of ethnic minorities were singing and dancing.Knowing that this transformation took a long time, everyone was mentally prepared, and some even brought musical instruments to spend the night.

With the performance of the music, everyone became more and more interested, and many people joined the dancing team unwilling to be left behind.Although no one knows how to dance minority dances, no one can laugh at themselves, so everyone's courage gradually grows.

As the number of dancers increased, people sitting outside who had no intention of dancing had to move back to make room for dancers.Many people who could sing minority songs also sang along, and those who were supposed to be listening to the wind and sand in the tent all joined the chorus one after another.

More and more people sang and danced, and those who couldn't sing danced along. In the end, everyone joined in.Each person holds a lighting lamp, nearly a million people, nearly a million lights, forming a spectacular scene in this desolate Gobi desert.

Even Wang Zhen, who was sitting in the off-road vehicle and watching the excitement with a smile on his face, was pulled out of the vehicle and joined in the sea of ​​singing and dancing.Looking at the singing and dancing crowd in front of him, and nearly a million lights flashing at the same time, Wang Zhen couldn't help but feel excited.

In order to leave a record for this desert greening transformation, Kaitian Group specially prepared various photographic equipment.Following the crowd dancing for a while, Wang Zhen suddenly wanted to leave a moment of eternity for everyone watching the lively crowd.

With the video camera on his right shoulder and the digital camera in his left hand, Wang Zhen climbed directly onto the tallest truck.With the rotation of the body and the pressing of the shutter, the sea of ​​lights of millions of lights, the dancing postures of the people, the excited smiling faces, all the beautiful moments are recorded as eternity.
