Yu Yifeng nodded slightly, this is also true.

With the development of fast breeder reactors in recent years, not only a small amount of uranium-235, but also more uranium-238 has been used. So far, there is no shortage of energy for the time being.

However, with the establishment of a large number of industrial systems, the future electricity consumption will inevitably increase exponentially. In particular, the manufacture of a large number of high-tech materials requires a large amount of electrical energy...... According to this statement, the development of new energy must be on the agenda.

Yu Yifeng asked, "What kind of energy do you think is more suitable for development?" ”

William thought for a moment and said directly: "There are two options that come to mind, the first is to develop geothermal energy and use large-scale geothermal energy to generate electricity. Second, develop solid methane in the Arctic and Antarctic regions, that is, fossil fuels! ”

"There do not seem to be active volcanoes in the Arctic and Antarctic regions of Nix, where the geological activity is weak, the average temperature is minus 200 degrees Celsius, and organic minerals such as combustible ice are stored, which is the ideal energy source......"

"Of course, the planet is rich in living matter, and there is also the possibility of oil. But we haven't found ...... yet."

According to the great engineer William, he was more inclined to develop combustible ice in the Arctic, or to find some reliable oil reserves.

Geothermal energy is too cumbersome, requiring all kinds of exploration, laying foundations, and the final power generation is often limited.

Thermal power is different...... It's the most widely used mode of power generation on the planet!

Methane, also known as natural gas, is one of the most stable ways to supply energy, and the excellent combined cooling, heating and power generation system can increase the efficiency of gas-fired power generation to more than 95%!

There is too much combustible ice in the Arctic to count, and if it could be mined in its entirety, it would be enough for tens of thousands of years of human use today......

Yu Yifeng thought about it carefully and quickly nodded in agreement.

The Arctic region is about 3,000 kilometers away...... Not too much of a problem. Anyway, people use empty boats for automatic transportation, and they don't need manpower at all. It doesn't matter if it's a long journey, just build a few more!

With the huge resources of a huge planet to feed 60,000 people, human beings are like a big extravagant and wasteful dog, completely devoid of the previous sense of conservation......

So, even if there is no uranium, it is nothing, people have methane, and there is an abundance of oxygen in the atmosphere. Burning fossil fuels is still the cheapest source of energy.

"I'll arrange this plan as soon as I get back." Yu Yifeng agreed: "The mining of combustible ice will be a higher priority, and Noah will need more organic matter......

As the two spoke, the high-speed train stopped again and came to the last stop.

That is...... Mysterious B11 area!

"This is the B11 area, which contains a lot of minerals such as copper, water, iron ore, sulfur, volcanic rock, etc. A total of 30,000 automatic excavators work here. William explained.

Yu Yifeng stepped down from the car and witnessed a large number of transport trucks moving back and forth, but in just three minutes, the train they came to was loaded with minerals.

The train then roars away to transport the minerals back to the central smelting center......

This gave him a rugged aesthetic of the 19th century steam age, except that human technology has now improved countless times.

The train is no longer the steam train of the past, but a more powerful maglev high-speed train, and smelting is not the smelting method of the past.

Humanity fights the endless darkness of the planet Knicks with steel and fire!

He believes that this spark will eventually ignite the prairie and illuminate the entire planet.

"At present, the amount of copper ore excavated is 67,000 tons per day, which is not a fast rate. But we didn't even have one percent of the excavators we had...... The process will be much faster in the future. William shook his head and said.

He watched it every day, and he didn't feel much anymore, and even somewhat adapted to this permanently dark planet.

He is still satisfied with the current progress of the project, but only slightly satisfied.

The last area they visited, B11, is about 173 kilometers from the central area, which is close to the extinct volcanic crater and is the richest area ever discovered.

And most importantly...... There is a bottomless cave in this area!

An underground cavern full of geothermal heat as well as life!

It was this karst cave that gave Yu Yifeng an inexplicable sense of weirdness.

There was also a reason why he insisted on going off the Noah to make a round. But what happened, he couldn't say.

Because of the large number of mineral and biological resources in the B11 area, this small base is home to more than 100 people, most of whom are biologists, geographers, and a small number of soldiers.

Standing at the gate of the base was none other than Captain Zhao Yao, who was on guard duty. Seeing Yu Yifeng, he was stunned for a moment, his mouth turned up, and he saluted solemnly.

Yu Yifeng also returned a salute, and the two didn't say anything.

He stood at the gate of the base and took a closer look, it was an A003 base ship. The perimeter of the base is filled with hills of minerals, waiting to be transported by train.

You can hear the roar of excavators and drills everywhere, and this area is really lively!

When many scientists heard that Yu Yifeng was coming, they had already greeted them at the door in advance, and the others also hurriedly put down their work and walked out of the door.

On the one hand, for the sake of welcome, on the other hand, there is indeed a lot to report.

"Captain, when will the exploration of the large karst cave begin?" A biologist was also direct, and he said it directly the first moment he saw Yu Yifeng.

"Mr. Yu, so far we have discovered 113 species of fungi and plant lifeforms, and the monitoring equipment has also found some insects! Unfortunately, no specimens were captured...... If you go further down the cave, you might find more! ”

“…… Mr. Yu, I have an important geological report here! ”

A large group of scientists hurriedly surrounded Yu Yifeng, they didn't have so many rules as soldiers, they wanted to say whatever they wanted. This is also the usual atmosphere in Noah, which is used to by Yu Yifeng.

Yu Yifeng hurriedly waved his hand, and his surroundings suddenly fell silent.

He read a few reports and said seriously: "Everyone should also know the priority of work, eat the meal in one bite, and take steps step by step." That's all we have at the moment, and we can't do it half-heartedly. ”

"Our primary goal in biology is for the human immune system to adapt to the planet's microbial environment and not get sick easily. The primary goal of engineering is to build an industrial system that is strong enough to prepare for the large-scale scientific research projects of mankind in the future. ”

"Until these two tasks are completed, we can't split the staff to do other things. The terrain of this cave is complicated, and the exact situation is still unknown, and the robot has explored the interior for 3,000 meters and still has not reached the end. Obviously, it's another big project......"

Seeing that the scientists were about to stop talking, Yu Yifeng said again: "After all the priority work is done, I promise to send soldiers to explore it...... Not now, though! ”

His words are still very reasonable.

The scientists are reasonable people, and they are eager to explore the cave, but at best, they are just curious.

In fact, they don't have time at all, just a large number of strangely constructed alien microorganisms are enough for them to eat a pot!

Before the development of immunization vaccines, how can there be time to study other vaccines?
