It's a good thing that students are able to ask questions aggressively.

However, before asking questions, you should learn more about experimental knowledge, instead of holding questions and asking questions without investigating and researching.

This is not a sign of humility and studiousness, this is a sign of laziness.

This also proves a problem, Jiangcheng University of Technology does have a big gap in the quality of students and first-class universities.

However, Zhou Xiao still answered this question very patiently.

He said: "What you just said is that it is simpler to use waste incineration to generate electricity directly than we use microbial colonies to generate electricity, and there are many waste incineration power plants in the world, including Xia country. ”

"However, there are a few key issues that you should have overlooked."

"The first problem is the pollution of waste-to-energy incineration. Plastic products are polymer organic compounds, which can indeed be burned and release heat, but there is no good way to deal with harmful substances such as dioxins after combustion, and they will be directly emitted into the atmosphere. But microbial power generation does not. ”

"The second problem is the efficiency of the conversion of thermal energy. The heat generated after the combustion of organic matter is not all absorbed and converted into electricity, and there is also energy loss, and if our multipolar colony decomposition tank does well, we find a way to improve the conversion rate of bacteria to energy, and the energy conversion rate of the colony power station will be close to the direct combustion of garbage. ”

"The third problem is that microbial technology is also used in the treatment of waste-to-energy incineration. Some garbage is incinerated after recycling through anaerobic fermentation, which is actually similar to us. ”

Zhou Xiao threw out three explanations in one breath, making the girl who asked the question red-faced.

The girl hurriedly said, "I'...... I'll come down and find out more. ”

"What's your name, how big is it?" Zhou Xiao asked with a smile.

"My name is Xia Ying, a first-year student majoring in microbiology."

"Freshman?" Zhou Xiao asked Dean Guo, "Freshman students also come here for internships?" ”

Dean Guo hurriedly explained: "We let the first-year students come over in batches, which can be regarded as setting their own goals for the future. ”

The score of Jiangcheng Institute of Science and Technology Life Science is very high, and the score of microbiology is the highest.

Dean Guo asked the first-year students to have a long insight, but also to let them realize some of the top content of this course in advance.

Zhou Xiao nodded and said no more.

Xia Ying was already red-faced at this time, and whispered to her best friend Liu Jiajia: "Now I am embarrassed and embarrassed, how can I ask such a mentally retarded and embarrassing question." ”

Liu Jiajia looked at Zhou Xiao with a look and said, "Where is there!" 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 Dean Zhou is also very young, it doesn't matter how old we are. ”

Liu Jiajia began to imagine the future: "If only I could join the Source Group to work in the future!" Just like Teacher Mo Li in the laboratory! Yes! Perfect! ”

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

Xia Ying looked at Zhou Xiao and then at Mo Li beside Zhou Xiao, thinking about when she would be able to become so good, be able to enter the origin group to work, and even be able to provoke the pillars of the project.

Dean Guo asked some first-year students to observe the experiment this time, but in fact, the purpose was achieved.

Many first-year students, Xiang Xia Ying, Liu Jiajia and others have established their correct view of the university and know what they should do in college.

In fact, Zhou Xiao also disliked that the experiment was more troublesome, but the reason why he wanted to use special-shaped digestive bacteria, Zhou Xiao also had a more important attempt.

That is to test whether the alien digesters can actually turn garbage into high-energy substances.

Theoretically.

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

Theoretically.

You put your poop into a multi-polar decomposition pool of digestive bacteria and alien digestive bacteria, and your poop will eventually turn into a high-energy substance.

These high-energy substances are salvaged, mixed together, and then dried, and finally they can be turned into high-energy energy blocks, which you can eat again.

Then you'll have poop again, but because of the energy loss, this time it's a lot less than the last one.

You also don't have to worry about high-energy food being unhygienic.

Digestive bacteria hate other bacteria the most, what Escherichia coli, Gram bacteria, etc., are directly killed and even digested by digestive bacteria.

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

Don't look at the current Xia Kingdom, most people are able to eat well.

This kind of living state is what we have always adhered to the red line of 1.8 billion mu of cultivated land.

It is guaranteed by the fact that there are still 740 million people engaged in agricultural production in Xia (2018 statistics bureau data).

Even if this is not enough, Xia still needs to import 108 million tons of grain from overseas every year to achieve it.

Behind the Xia people's full food and drink, there is a very dazzling data of this scene.

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

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

These data all prove that Zhou Xiao's experiment is of great significance!

If the alien digestive bacteria were able to use various organic matter to create a food of universal significance, or a new type of food.

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

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

The means that can affect the fate of every country in the world are none other than energy and food.

If Xia can use this technology to export a large amount of grain overseas, it will not only be able to get rid of the embarrassing situation of Xia Guo frantically importing grain, but will even be able to exert extensive influence on more countries.

Therefore, only Zhou Xiao knew that the existence of alien digestive bacteria was of great significance.

After the site is surveyed, the construction unit will cooperate with the laboratory to use it as soon as possible.

Moli's team will also hand over the design of the multi-layer colony tank drawings 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." ”
