In February 0010, more than ten years before the explosion of the earth......

After two months of research, calculations, discussions, and verification, the group of scientists finally figured out the initial budget for the entire fusion project......

That is, the entire project budget for the "nuclear explosion reactor" plus the "spacecraft". Ｘ

This meeting was very grand, and it was also the first big meeting after the Chinese New Year.

It is said that there is a real plan to cross the "big filter", and many high-level government officials and engineers have caught up from the surface. Of course, they had heard some gossip beforehand, and they were a little prepared.

But this little preparation was soon shattered by the frenzier reality......

During the meeting, Yu Yifeng looked out the window with a blue face......

Not only him, but many people also looked around, or held their heads in their hands, or discussed in a whisper, in order to hide their panic emotions......

"Things in the world are always so hard."

Yu Yifeng thought secretly in his heart: "I want endless energy...... It's not always easy, it's really not easy. ”

The universe is vast and unimaginably vast. Similarly, the dangers of the universe are unimaginable, with supernova explosions, gamma-ray explosions, black hole devouring, planetary collisions, and all kinds of astronomical disasters that can wipe out life with just a ripple.

But strangely enough, the universe is full of life!

Life is like garbage here, everywhere. Even the wisdom of civilization is the same, everywhere is ......

In this case, the big filter is in the middle, but civilization and civilization are so lonely, like an island in the vast sea.

Civilization, in this isolated island, enjoys its own sweet dreams.

Civilization is trapped on its own planet alone, not knowing each other's existence, not knowing how each other is doing...... In this way, old age and death do not get along.

True interstellar civilizations are like gems in the desert, rare and terrifying.

Fortunately, humanity has encountered a small probability event in a small probability, and mankind has seen a real interstellar civilization!

Yes, it's good luck to have seen it!

Otherwise, there will definitely be a feeling that the road ahead has been cut off.

But ordinary civilizations, most likely have not encountered interstellar civilizations, what will they think when they encounter the "big filter"? Will they be as determined and crazy as the new humans?

Most likely, it won't ......

Yu Yifeng came back to his senses, no longer thinking about these messy things, and a number popped up on the screen in front of him, which was also a number that made him feel extremely annoyed.

"34.86 billion tons?!" He grabbed his head and vigorously ripped off a few of them.

As soon as he turned his head, he suddenly saw Wang Yufan's confused eyes, and the two of them looked at each other, and smiled bitterly at the same time.

There is a reason for this wry smile, and it is also brought about by this number.

34.86 billion tons, as soon as he thought of this number, Yu Yifeng felt a burst of emptiness, and even lost the concept of numbers.

More than 1,000 engineers and scientists were sitting in the conference room, and a group of high-ranking government officials, all of them with incredible expressions......

"As you can see, yes, we are going to build four huge reactors with a diameter of about 15 kilometers. It is completely possible to easily eat a nuclear bomb with a yield of one million tons......"

Professor Ding Yidong explained feverishly on the top, while spitting out a bunch of incredible terms.

"The total consumption of steel is about 34.86 billion tons, and the accumulation of various superalloys is 1.33 billion tons, aluminum alloys, superconducting materials...... Unfortunately, these are only preliminary budgets, and it is unknown whether they will be exceeded. ”

These Noah's high-level executives were already stunned, and they didn't know what the hell Ding Yidong was talking about.

What is ...... called? 4 super-large nuclear fusion reactors with a diameter of 15 kilometers?

Even if you have one, you have to build 4 more?

4 pcs!

34.86 billion tons?!

100 million tons?

Hundred million......

And that's not all, there's a lot of other stuff out there!

Do you really think it's tens of billions of tons of mud? It's a metal, and it needs to be made with energy! And with so much steel, it's not just a random pile, it needs to be built decently!

…… Build!

The earth's annual steel production is 1.6 billion tons...... It takes a total of 22 years to produce more than 30 billion tons of iron!

How many people are there on the earth, and how many people are there in the new human civilization!

This group of people looked at the text report in their hands with confused eyes, and the content was really written very clearly, all kinds of formulas, all kinds of data, very clear. Some even pinched their thighs hard to prove that they weren't dreaming.

"Guys, don't you want to think about it, this is a big filter! If it really were that easy to achieve, would there be fewer interstellar civilizations? ”

"There are only two ways for the big filter, one is the 'magnetic confinement', and the other is this? What better way, you can say. ”

Ding Yidong saw everyone's shocked looks, and shouted impatiently.

"There are not many reactors at all, so they can be substituted at any time and can be used interchangeably. Do you think such reactors don't need maintenance? There's a living nuclear explosion in there! ”

"Of course, the economic scale of these super-large reactors alone is enough to kill low-level civilizations, at least hundreds or thousands of times the global GDP. Ordinary civilization simply does not have the power to do such a project! ”

"But we are a new human civilization! If it happens, we will have access to almost infinite energy, infinity! ”

Ding Yidong roared wildly, the thought of doing such a huge project made him extremely enthusiastic, and he didn't care if he could complete it in this life......

As soon as his words came out, everyone present was suddenly awe-struck, and there were many people who supported him, and there were no longer a few who were silent.

Indeed, is it so simple to have a large filter?

This road seems simple, but it is actually not easy to walk...... The huge amount of work has become the biggest problem.

Yu Yifeng also shook his head and smiled, although he had been mentally prepared for a long time, it was actually more exaggerated than he imagined.

The material needed to generate electricity by exploding a nuclear bomb is a nuclear bomb. The universe has played another joke on civilization, as if it were deliberate.

tritium, tens of millions of degrees can start a nuclear fusion reaction, nature, no;

helium-3, 100 million degrees, extremely rare;

Deuterium, 500 million degrees, abundant in abundance;

Radium, that is, ordinary hydrogen, requires a reaction of more than 1 billion degrees, massive!

What the is this...... The universe is absolutely deliberate!

The only ones that can be obtained on a large scale are four-hydrogen nuclear bombs or deuterium bombs, and the "ball-shaped" structure of these two nuclear bombs is destined to have a yield that cannot be too small.

So...... The reactor can only be made large enough and strong enough to reduce the difficulty of nuclear fusion with a large amount of engineering!

A nuclear bomb with a yield of one million tons can release 4.184*10^15 joules of energy, which is equal to ...... 1.152 billion kilowatt-hours of electricity, about one-tenth of the daily electricity consumption of the entire Huaxia.

Even if one could only collect one percent of the energy of a nuclear explosion and use it to generate electricity, it would be more than 10 million kilowatt-hours......

What is more than 10 million degrees?

This number may not be intuitive enough.

According to Ding Yidong's plan, a nuclear explosion reactor will have a supporting generator power of about 10 billion watts.

After a blast, it can last more than 4,000 seconds to emit more than 10 million kilowatt-hours of electricity.

Well, this is nuclear fusion, 10 billion watts of power generation, it seems really exaggerated......

Very, very exaggerated, people's current electricity power is less than 100 million ...... r
