Chapter 302

It is a good thing that students can actively ask questions.

But before asking questions, you should know more about the experimental knowledge instead of holding the questions. You should ask questions without investigation and research.

This is not a sign of being open-minded and eager to learn, but a sign of laziness.

This also proves that there is a big gap between the quality of students in Jiangcheng University of technology and first-class universities.

However, Zhou Xiao answered this question very patiently.

He said: "you just said that it is easier to directly use waste incineration to generate electricity than we use microbial colonies to generate electricity. This is indeed the truth, and there are many waste incineration power plants all over the world, including Xia country."

"However, you should ignore several key issues."

"The first problem is the pollution of waste incineration power generation. Plastic products are high molecular organics, which can indeed burn and release heat, but there is no good way to deal with the harmful substances such as dioxins after combustion, which will be directly discharged into the atmosphere. But microbial power generation will not. "

"The second problem is the conversion efficiency of heat energy. Not all the heat generated by the combustion of organic matter is absorbed and converted into electric energy, but also has energy loss. If our multipolar colony decomposition tank is well done, we will find ways to improve the energy conversion rate of colonies, and the energy conversion rate of colony power station will approach the direct combustion of waste. "

"The third problem is that microbial technology is also used in the treatment of waste incineration power generation. Some garbage will be burned only after anaerobic fermentation after recycling, which is actually similar to us. "

Zhou Xiao threw out three explanations in one breath, which made the girl who asked the question blush.

The girl quickly said, "I... I'll come down and learn more."

"What's your name, how old are you?" Zhou Xiao asked with a smile.

"My name is Xia Ying, a freshman majoring in microbiology."

"Freshman?" Zhou Xiao asked President Guo, "freshmen also come here for internship?"

President Guo quickly explained, "we let freshmen come and have a look in batches, which can be regarded as setting our own goal in the future."

The score of Jiangcheng Institute of life sciences of science and technology is very high, among which the score of microbiology is the highest.

President Guo asked freshmen to gain insight, but also to make them realize some of the top contents of this course in advance.

Zhou Xiao nodded and said nothing more.

Xia Ying blushed at this time and whispered to her best friend Liu Jiajia, "now I'm losing face and hair. How can I ask such a retarded and embarrassing question."

Liu Jiajia looked at Zhou Xiao and said, "where there is, where there is! Don't you think Dean Zhou was very handsome when he answered the question just now! The boy's serious and serious appearance is really handsome! I think President Zhou is also very young. It's no big deal how old we are. "

Liu Jiajia began to imagine the future: "if only I could enter the origin group to work in the future! Just like teacher Mo Li in the laboratory! Ah! Perfect! "

Liu Jiajia's fantasy is also Xia Ying's fantasy.

Xia Ying looked at Zhou Xiao and Mo Li around Zhou Xiao, thinking when she would become so excellent, be able to enter the origin group and even start the project.

President Guo let some freshmen observe the experiment this time. In fact, the purpose has been achieved.

Many freshmen, such as Xiang Xiaying and Liu Jiajia, have established their correct view of University and know what they should do in University.

In fact, Zhou Xiao also disliked that the experiment was troublesome, but Zhou Xiao still had an important attempt to use alien digestive bacteria.

That is to test whether alien digestive bacteria can really turn waste into high-energy materials.

In theory.

These high-energy substances synthesized by alien digestive bacteria are actually edible to humans.

In theory.

You put your stool into the multipolar decomposition tank of digestive bacteria and alien digestive bacteria, and your stool will eventually become high-energy material.

Salvage these high-energy materials, put them together, dry them in the sun, and finally turn them into high-energy energy blocks, which you can eat

Then you will have poop again, just because of the energy loss, this time the poop is much less than the last time.

You don't have to worry about unsanitary high-energy food.

Digestive bacteria are the most annoying of other strains. E. coli, Gram-negative bacteria and so on are directly killed or even digested by digestive bacteria.

This experiment is not disgusting, nor is it Zhou Xiao's brain wrong. He deliberately wants to make an experiment, but it has great scientific value and practical significance.

Don't look at the current Xia state, most people can eat well.

Such a living state is obtained by adhering to the red line of 1.8 billion mu of cultivated land.

It is guaranteed by the fact that there are 740 million people engaged in agricultural production in Xia country (data from the Bureau of statistics in 2018).

Even this is not enough. Xia has to import 108 million tons of grain from overseas every year.

Behind the fact that the people of Xia had enough to eat and drink, there was a very dazzling data of this scene.

If you look at the world, there are not many countries that can really eat and drink. According to the data given by the United Nations, almost 900 million people in the world are hungry.

The leftover rice or meat you eat every day is something that the population of many countries (especially African countries) have never seen. The food you throw away is a gluttonous feast in their hearts.

These data are proving the significance of Zhou Xiao's experiment!

If alien digestive bacteria can use various organic substances to create a universal food, or new food.

Then this technology can liberate the land and labor of Xia country to the greatest extent and truly complete the last puzzle of urbanization of Xia country.

If the experiment is really successful, people around the world will redefine food, and the technology will also alleviate the global poverty crisis to the greatest extent and help people eat enough.

The means that can affect the fate of countries around the world are nothing more than energy and food.

If Xia can use this technology to export a large number of grain overseas, it can not only get rid of the embarrassing situation of Xia's own crazy import of grain, but also have a wide influence on more countries.

Therefore, only Zhou Xiao knows the significance of the existence of heteromorphic digestive bacteria.

After the site survey, the construction unit will cooperate with our laboratory for use as soon as possible.

Mo Li's team will also submit the design drawings of multi-layer colony pool to the construction unit.

Zhou Xiao looked at the ruins and garbage in front of him and said, "this will become the most dazzling place in Jiangcheng."
