Chapter 237: Wang Cheng's Greatest Worry

After Zhang Wen entered.

He immediately saw that the parameters were abnormal.

After all, the power consumption is frighteningly high now.

Basically, it's about five times that on the Moon's sunlit side.

But what is fortunate is that.

The survival base indeed withstood this extreme low temperature.

Zhang Wen left the survival base here.

He then boarded the Kunpeng.

He returned to the location of Dongda's lunar lander.

He needed to wait a day or two.

To restart the survival base.

To see whether the survival base could, without power,

rely on its own structure to resist this degree of cold.

Zhang Wen quickly piloted the Kunpeng to the place where the lunar lander was.

To see if they needed any help.

As soon as Gao Jiaomu saw Zhang Wen arrive,

he immediately pulled Zhang Wen aside.

"Do you think there are any problems with this landing?"

"I always feel this time is too smooth."

Gao Jiaomu's personality is to ensure everything is flawless.

Moreover, Zhu Xinghan's original task for him was to study the problems

that arise during the lunar landing, as well as any possible problems.

After all, this lunar landing is merely a rehearsal.

Although there are some scientific tasks, the main goal is to accumulate experience.

After all, with Zhang Wen's Kunpeng, rescue can be carried out at any time.

But next time will definitely be a worldwide live broadcast.

Zhu Xinghan does not want any problems.

Moreover, under a worldwide live broadcast, Zhang Wen certainly cannot appear.

The Kunpeng also needs to remain hidden for a while as a final nuclear countermeasure, like a nuclear submarine.

In fact, now only the top leadership of Dongda knows about the Kunpeng.

Everyone else is kept in the dark.

After all, this is no joke.

It is a nation's most important trump card.

Therefore, it must absolutely not be exposed to others.

Therefore, the second wave of people going to the Moon

can only rely on themselves.

Of course, if an unexpected situation arises requiring Zhang Wen to intervene for rescue,

we can cut the live broadcast and then carry out the rescue.

The reason can be made up later.

It must be said, Zhang Wen's Kunpeng has greatly increased the fault tolerance of the space program.

Especially in the exploration between space and the Moon.

Zhang Wen thought about what problems there might be.

but he found none.

So he told Gao Jiaomu, "My ship is different from yours; you figure it out yourself."

"I'll keep digging my helium-3."

Zhang Wen immediately went to dig helium-3.

Thus two days passed.

Zhang Wen returned to the survival base again.

After restoring power, he saw the survival base was intact and all functions could operate normally.

Zhang Wen then brought the survival base back to the Tiangong.

He then returned to the Moon, carrying helium-3, and together with the astronauts' lunar lander, returned.

After Zhang Wen gave a greeting, he went back.

The astronauts still used the conventional method to return to Earth.

But Zhang Wen did not expect that.

At the moment he landed on Earth,

he simply could not stop.

Inside the Dongda Nuclear Fusion Research Institute,

Director Wang Cheng is now worried to death; although the development of nuclear fusion is progressing astonishingly,

especially their fully superconducting nuclear fusion experimental device,

the results are even more gratifying.

It can now operate stably for a thousand seconds.

That's a full thousand seconds.

After all, nuclear fusion is not nuclear fission.

The reaction of nuclear fission is very stable, but nuclear fusion is completely different.

The difficulty is roughly equivalent to a person walking one meter and hiking around Dongda in 24 hours.

Anyone with common sense can see it's impossible at a glance.

In reality, it's also close to impossible.

After all, if a stable nuclear fusion reactor is achieved.

It would be equivalent to having infinite energy.

True infinite.

If we take an example of nuclear fusion that everyone in the world knows.

That is the sun rising in the east and setting in the west every day.

Its interior is constantly undergoing endless nuclear fusion.

Only one two-billionth of the energy it produces can be used by Earth.

If expressed in numbers, that would be an unknown number of zeros.

So, wanting to achieve stable nuclear fusion is like challenging an omniscient, omnipotent god with mortal wisdom.

Originally, Wang Cheng's experimental progress was quite promising.

But now he has hit a bottleneck, and for over a year he has produced no experimental results.

The nuclear fusion result also stabilized at a thousand seconds, with no further progress.

Wang Cheng went from initial confusion to later wanting to discover and solve the problem.

After a series of experimental studies.

He then discovered.

It turns out the nuclear fuel currently used is tritium, although the temperature requirement can be said to be relatively low.

But the neutron radiation caused by its nuclear fusion reaction is truly too severe.

Even the strongest material found so far by Dongda.

Under such neutron bombardment.

It also cannot withstand it for long.

That is why the final result of the full superconducting nuclear fusion experimental device can only stay at a thousand seconds.

After all, if it were to persist a little longer.

The full superconducting nuclear fusion experimental device would have to put on an explosive performance on the spot.

And the explosive power of nuclear fusion.

It is stronger than nuclear fission by an unknown amount.

Now he wants to solve this defect.

There are only two ways.

One is to find stronger radiation-resistant material.

But the progress of materials science now.

Can be said to be slow.

In fact, most of the difficulties in physics and engineering today are due to the lack of progress in materials science.

They are the ones who have not made progress.

In physics and engineering, no matter how brilliant the idea.

It cannot be turned into an actual product.

The biggest constraint is the lack of suitable materials.

If suitable materials appear, all kinds of strange inventions can emerge.

But since materials science has made no progress, there really is no way.

After all, this is not something he can decide; the current way materials science develops.

Only endless trial and error.

When luck is good and a trial succeeds, that is development.

When luck is bad and nothing comes of it, all that can be done is to keep waiting.

There is still another way left.

That is to replace the material.

But replacing the material is also very difficult.

Now there are only two routes.

One is the current deuterium-tritium route.

The other is the helium-3 route.

The advantage of helium-3 happens to solve the biggest problem Wang Cheng currently faces.

Neutron radiation.

Although the temperature requirement almost doubles.

But temperature after all still has a solution.

However, the key problem now is.

There is no helium-3.

Now, at most how many kilograms can we bring over for use in the lab?

And when the fusion device is turned on.

That's how much consumption there is.

Now this amount is simply not enough.

Mainly because the cost cannot be reduced.

After all, the helium-3 on Earth.

The estimate is only close to 5 tons.

It's really too little.

Not only is it scarce, but the mining difficulty is extremely high, making it impossible to extract much.

Just at this moment.

Wang Cheng received a phone call.

"Old Wang, do you need helium-3 over here?"
