Bright Sword starts with the grenade flat.

Chapter 304: There are only technologies that are used in the wrong place, and there are no useless technologies.

So Liu Xiu began to recall in his mind the information about artificial starch that he had seen before traveling through time.

Among them, the most interesting report about synthetic setting powder is that the energy contained in each kilogram of setting powder is 17 million joules, which is approximately equivalent to the energy of 4.9 kilowatt hours of electricity.

However, due to the low energy utilization rate of this artificial synthesis, which is less than 20%, it means that the synthesis of one kilogram of starch requires about 25 kilowatt hours of electricity.

However, the price of one kilogram of sweet potato powder on the market is only fifteen yuan. There is no way to specifically cultivate sweet potatoes, and the amount of powder produced is too high, and sweet potatoes are also particularly easy to grow.

However, the price of 25 kilowatt-hours of electricity was one yuan per kilowatt-hour for industrial electricity in the period before Liu Xiu's time travel. Therefore, the cost of using industrially synthesized electricity for one kilogram of fixed powder is twenty-five yuan. In this way, artificial synthesis The technology of fixing powder is ridiculed as a useless technology.

There is not even any commercial application prospect and practical value. After all, the cost of using photosynthetic solar energy from plant cultivation is not much lower than the cost of generating electricity to synthesize fixed powder by oneself.

Therefore, after Liu Xiu's artificial powder-fixing technology was reported before his time travel, it was just a flash in the pan. Most people had only heard of it. In the future, people will not need to rely on planting but rely on industry to survive. The profession of farmers will become history. At that time, most people were naturally surprised.

Then when most people looked at the specific report, good guys, not counting the machine cost, but only the production cost, the price of artificially synthesized fixed powder was actually twice the cost of farming, so there was a lot of ridicule on the entire Internet. , this synthetic powder fixing technology has no further details, and it is most likely that it has been collected!

After all, this technology is probably a reserve technology, that is, it can be used for emergency purposes in the event of a famine or disaster that results in a food harvest failure, such as the great famine in the early 1960s. If this technology existed, Even if the production cost is twice as expensive, it doesn't matter.

The second aspect is to breathe in oxygen and expel carbon dioxide. You must know that the weight of carbon dioxide exhaled by people every day reaches more than one thousand grams! If you do heavy physical work, it will be even more, even more than two kilograms of carbon dioxide.

"Hurry up and summon the world's top chemical experts to set up a research group specializing in synthetic powder! Their research direction is wrong. To solve the problem of underground city food, we should not only rely on agricultural biology experts, but also on industrial chemistry. Expert in the field!”

Hao Xiaoxi, who was always on standby to obey Liu Xiu's orders, was stunned for a moment when he heard Liu Xiu's words. Then he immediately turned around and left Liu Xiu's office to carry out Liu Xiu's orders.

But this setting powder is perfect at this stage. The main raw material for artificially synthesizing setting powder is carbon dioxide. In the underground city, human excrement mainly has two aspects. The first aspect is feces and urine. .

In this way, if the synthetic powder fixing technology is developed, the breathing and food problems in the dungeon can be solved very well.

That's right, Liu Xiu's current secretary is the assistant secretary who followed Zhou Zhezhi in the plot of Traffic Blue Star II.

Thinking of this, Liu Xiu did not hesitate to call his secretary Hao Xiaoxi and said:

And now Liu Xiu has taken advantage of the helium flash crisis to unify the world, so naturally there is no need for the diplomatic unit.

That's right, the diplomatic unit was revoked by Liu Xiu, so Hao Xiaoxi, who had excellent work ability, was recommended to Liu Xiu by Zhou Zhezhi. Liu Xiu saw that Zhou Zhezhi's ability was indeed good. He was not only able to withstand pressure, but also worked seriously. He was meticulous in his responsibility, so he regarded Hao Xiaoxi as one of his assistant secretaries.

There is no way, after all, now that the world has been unified, Liu Xiu's rights are much greater, and he can basically rule the world, but the greater the rights, the greater the responsibility, and the greater the pressure. After all, now Now the lives of eight billion human beings around the world are in his hands, Liu Xiu! Therefore, there are more things that need to be dealt with, so the secretarial team is required to organize and summarize all the things and report them to Liu Xiulai to save Liu Xiu's processing time.

And Hao Xiaoxi's ability to do things is also very good. Within three hours, he came over to report to Liu Xiuhui:
"Liu Xi, the top 100 top chemical experts in the world are already in the conference room!"

Liu Xiu was stunned for a moment after hearing Hao Xiaoxi's words, and then said:
"Is it so fast? The gathering was completed in just three hours?"

When Hao Xiaoxi heard Liu Xiu's question, he replied:

"I asked the air force bases around the world to cooperate, and the task force picked up the people, and then flew over in the Sword 20C using supersonic cruise!"

Liu Xiu nodded and was not surprised after hearing what Hao Xiaoxi said. After all, the Jian 20C can not only take off and land vertically, but can also fly for a long time at a supersonic cruising speed of two thousand kilometers per hour, so three hours Just completing the assembly is normal.

Then Liu Xiu, led by Hao Xiaoxi, came to the conference room where the world's top chemists gathered.

With the arrival of Liu Xiu, the originally noisy conference room suddenly became quiet.

Some of the world's top 100 chemists in the conference room were still wearing slippers and pajamas. It was obvious that Liu Xiu's task force ignored the situation as soon as they heard that Liu Xiu wanted to summon chemical experts urgently. What are the experts doing?

It is very likely that some chemists are sleeping at home! However, the task force broke into the door, and then forcibly pulled him up from the bed, stuffed him into the back seat of Sword 20C, and brought him directly here.

At this time, 40% of the top 100 chemical experts on the global rankings are from Huaxia District, and the rest are from other districts, such as Mi'ao District and Ouzhou District.

Liu Xiu looked at the chemistry experts who looked unhappy, walked up to the podium without saying anything, bowed to them, and then said:

"Everyone, it's my fault to invite you here like this, but for the future of mankind and the survival of the eight billion people on Blue Star, I have to do this! Because according to the joint report of agricultural and biological experts, even though they have tried their best It's possible, but the space of the underground city is only enough to accommodate four billion people around the world to survive in the underground city, which is the limit of what the underground city ecosystem can accommodate!"

The hundreds of chemical experts in the conference room, who were originally angry because they were forcibly brought here, disappeared with Liu Xiu's bow just now, but suddenly became taller again with the second half of Liu Xiu's words!

One of them looked at a very young man in his thirties and said:

"But Liu Xi, we are chemical experts, not biological experts or agricultural experts. We have no way to increase the yield of rice and wheat! It's useless for you to ask us to come!"

When Liu Xiu looked at this guy, his deeds also came to mind. He was still very famous in organic chemistry, and he had already become a professor at a certain polytechnic university at a young age.
