Chapter 302 Three Major Difficulties

Yu Yifeng's first reaction was: Is it possible to directly use uncontrollable nuclear fusion?

But then again, just because of the "unsolvable" problems that currently arise in "controllable nuclear fusion", humans don't know what to do...

This is a huge theoretical constraint. No one knows how many years will pass before a genius will appear and solve these theoretical problems in one fell swoop.

Do people really have to take advantage of this situation and continue on the path of "magnetic restraint"?

Scientists are not that stupid!

Since "controllable nuclear fusion" was too difficult and complicated, they frantically came up with another plan...

Uncontrollable nuclear fusion!

This is what the Great Sage Nick thought before he died, a more feasible solution... "Uncontrollable nuclear fusion", this kind of thing has actually been realized by mankind a long time ago, isn't it a hydrogen bomb!

Why insist on being "controllable"? Can't we use the energy of a hydrogen bomb? ! If the energy of the hydrogen bomb could be harnessed, wouldn't it also become controllable?

This is... what these scientists really think!

Yu Yifeng's scalp went numb after hearing this. For the first time, he felt that this world was so crazy.

But in the next conversation, he knew...it's not just this world that's crazy!

This idea has already appeared in the time of the earth!

The Soviet Union and the United States both discussed this plan in the 1960s and 1970s, when nuclear research and development was booming: they tried to dig an underground cave in the deep mountains and old forests, conduct nuclear explosions repeatedly in the cave, and then use the heat of the nuclear explosions to Generate electricity...

"According to calculations, only 1,000 nuclear bombs with the equivalent of 3,000 tons of TNT can meet the power supply problem of a medium-sized and large city...According to our output, more than 100,000 nuclear bombs a year will not be a problem."

Professor Ding Yidong said with a smile: "Of course, that was a plan seventy years ago. There are still a lot of problems that have not been solved, so it was abandoned in the end."

"Nuclear bombs were quite expensive compared to the cost at the time. Using them to generate electricity was completely putting the cart before the horse. Moreover, large-scale manufacturing of nuclear bombs can easily cause nuclear leakage. It would be unthinkable if the nuclear bombs fell into the hands of terrorists..."

"But for us, there should be no such problem. There should be no terrorists in Noah's society..."

"We can definitely make the nuclear bomb bigger and more powerful, or we can use a spherical reactor instead of an underground cave, so that more energy can be collected."

Yu Yifeng looked at Ding Yidong's strange smile and shuddered in his heart. This old man has become more and more crazy since he regained his youth.

I guess he has been thinking about this plan for a long time, right?

But other scientists actually supported it, especially the conservative ones like Dr. Felix, who didn't have much opinion.

Is... is it really possible?

The more he thought about it, the more bizarre he felt, but he still kept calm enough and asked a series of questions: "Is this plan really feasible? Have you rigorously verified it? You can't just decide the direction of the entire civilization with a snap of your head!"

"Also...where does the tritium element for the hydrogen bomb explosion come from? Is it a helium-3 bomb? Or an ordinary tetrahydrogen nuclear bomb? The yield is too high, right? What about the cost of laser ignition?"

"...Have you considered safety issues? What if the boiler explodes?"

The scientists looked at each other. In fact, they had been discussing this plan for a long time, and they thought it was more reliable than magnetic confinement.

However, they felt that Yu Yifeng's words were on point. As a qualified leader, a cautious attitude is really the most important thing.

One of the experts immediately took the report in his hand and said: "Captain, regarding your question, we have compiled the relevant data."

"Using uncontrollable nuclear fusion does not mean that it can be done. It actually has certain difficulties and needs to meet three conditions."

"First, the research on nuclear bombs must be very in-depth. The energy used to make a small nuclear bomb must be much less than that released by the nuclear bomb. Otherwise, using nuclear bombs to generate electricity will be a joke!"

Yu Yifeng nodded, this is true.

Nuclear bombs are not ordinary missiles. They are very expensive to make. For example, to make an atomic bomb, highly concentrated uranium-235 is used. Just purifying this highly enriched uranium requires a lot of energy.

The entire energy used is even more than the energy released!

Besides, it is impossible for humans to collect all the energy released by nuclear bombs. Being able to use 10% or 20% is already very good!

In this way, if the energy expenditure is less than the income, then the power generation plan will definitely fail.

Seeing Yu Yifeng's thoughtful look, the expert continued: "Second, the raw materials for nuclear bombs must be very extensive, not rare tritium, and preferably not helium-3... otherwise it will still be unsustainable."

"We still have some helium-3, but the reserve is not particularly large. It is currently less than one thousand tons... This is also a problem."

"Third, there is the problem of the reactor. Of course we can dig a cave underground and explode a nuclear explosion inside, but in this case, most of the energy will be transferred to the ground, and the utilization rate of the nuclear explosion energy will be even lower."

"And if a nuclear bomb is detonated in a cave, the cave will melt under a long-term explosion, and it may even trigger a large-scale earthquake...the location needs to be changed frequently."

This list of difficult points shows that this group of scientists has really thought about this issue carefully.

Yu Yifeng frowned and pondered, undecided.

The scientist said again: "In fact, the Nix civilization also thought about using this method to obtain energy in the final stage... But they don't have enough tritium or helium-3, so they don't have enough raw materials for nuclear bombs, not even enough raw materials for ignition."

"But we have tetrahydrogen nuclear bombs, and the raw materials are extensive. We only need a small amount of tritium or helium-3 as an igniter to detonate. Although... uh... the equivalent... is a little bit larger, then we just need to make the reactor bigger!"

"Our nuclear bomb production technology... should be relatively mature, and the energy consumption is relatively low, which is a big advantage."

Yu Yifeng didn't know what to say anymore...

The technology for making nuclear bombs is awesome, and it seems to sound good... What is this? Is this also an advantage?

Normal civilizations develop in a peaceful mode in the later stages, and will not study nuclear bombs as crazy as the new human civilization.

Especially in the Earth period, weapons such as hydrogen bombs were gradually eliminated because of their high maintenance costs...

"As long as the deuterium-deuterium fusion reaction is enough, there is no need for a tetrahydrogen bomb." Professor Ding Yidong added: "The critical reaction temperature of this new type of nuclear bomb is only 300-500 million degrees, which is much lower than that of a tetrahydrogen bomb. The equivalent can be smaller and completely controlled within a million tons of equivalent..."

Yu Yifeng was sweating all over his head. What does it mean to only need 500 million degrees...

As long as it is 500 million degrees...

"A tetrahydrogen bomb needs more than 1 billion degrees! The equivalent can only be larger, and a smaller deuterium bomb is a better choice!"

The research on nuclear bombs has become a unique technology of the new human civilization, far surpassing the Nix civilization and the Earth civilization.

After all, with the solar explosion as an enlightenment mentor, human research on nuclear reactions has indeed taken a step forward.

However, the structure of this new type of nuclear bomb is similar to that of a tetrahydrogen bomb. It needs a helium-3 bomb or a hydrogen bomb to ignite. The equivalent cannot be reduced, at least it is at the million-ton level, which is a major difficulty.

What can withstand a nuclear bomb with a yield of one million tons?

A nuclear bomb with a yield of one million tons can destroy an area of ​​150 square kilometers and a city!

Yu Yifeng was really impressed...
