The founding ceremony of the Academy of Sciences ended.

Su Han called Su Xinghe over.

Secretly handed him a list.

Let him secretly solve a few people with rebelliousness.

If there is enough time.

Su Han had thought about observing several people secretly.

See where the problem lies.

But the problem is that he cannot stay at Mercury Base for a long time.

There is no time either.

What big data surveys are going to do?

The best way now is to evaporate these people.

To avoid creating unstable factors for the Mercury Academy of Sciences.

Su Xinghe is of course loyal to Su Han.

Although he didn't know why he had to clean up these people.

But no matter what the other party asks him to do.

He will obey unconditionally.

However, this incident also sounded a wake-up call for Su Xinghe.

The Academy of Sciences that is usually harmonious.

Not as simple as imagined.

At least the secret power that my dean arranged was hidden in it.

He didn't know anything about it.

It seems that it is better to be careful when doing things yourself in the future.

In order to avoid not even knowing how he died in the end.

...

Su Han lived at Mercury Base for a while.

Until the test was completed, the Jiaolong returned to the base.

He boarded the ship and took a look.

Finally, I left with satisfaction.

The Dragon Academy has also officially started research.

...

Two years later.

The new Thunderson B-type working fluid-free engine prototype is offline.

Su Han was of course very happy about this.

Although there are working fluid engines, the performance is very strong.

But it has a fatal drawback.

It's just that the fuel is consumed too quickly.

Although Su Han is constantly manufacturing mining machines.

The annual production of helium 3 has reached 2,000 tons.

But in the state of working fluid, it is not enough for a Dragon.

Having an operating fluid engine is destined to be an important support for him to travel across the stars.

The working fluid-free engine will become one of the most important trump cards in Su Han's hands.

After the test begins.

The engine's thrust continued to rise... Finally, it reached the extreme thrust of 230 tons.

Although this thrust is far less than that of a working fluid engine.

But the problem is that it is more fuel-efficient.

This is the meaning of the existence of a working fluid-free engine.

Su Han said: "By the way, Shenlong! How many Thunder Dragon B-type working fluid-free engines can be installed on a Jiaolong?"

Shenlong said: "The size of the B-type Thunder Dragon motor should be smaller than that of the A-type. A set of fusion devices can be used with about forty engines. The Jiaolong has two fusion devices, which means that it can be used with one hundred B-type Thunder Dragon engines."

Su Han said: "If our Jiaolong is equipped with the Thunder Dragon B-type engine, how fast can it fly as fast as possible?"

Shenlong said: "The B-type engine of Thunder Dragon is used to cut stars and planetary magnetic inductance lines for flight. Although the engine's thrust has reached more than 200 tons, the test site is Mercury, and it is close to the sun, so it can cut a very strong magnetic field. Under normal circumstances, the farther away from the star, the smaller the thrust. Of course, it is impossible not to have it. Because even if there are no stars and the magnetic field of galaxies, the thrust is not that high.

As for how fast it is possible to fly as fast as possible, after calculation, it should be possible to push the Dragon-class warship to half the speed of light without considering the time cost."

Half the speed of light!

Su Han was certainly excited when he heard this.

The speed of light is half.

This is already an amazing speed.

If your spacecraft can really have half the speed of light.

Then it is entirely possible to fly to the stellar system closest to the sun within ten years.

Su Han, who was a little excited, suddenly thought of something and said, "By the way, Shenlong! How many tons of helium three will be consumed to accelerate to the speed of light?"

Shenlong said: "It takes about 2,700 tons."

"So much!" Su Han frowned when he heard this!

There are ten thousand tons of working fluid.

Two thousand seven hundred tons without working fluid.

It doesn't seem to save much.

But considering that 10,000 tons is only 30% of the speed of light.

Two thousand seven hundred tons are 50% of the speed of light.

The speed is much faster.

It made him a little confused.

In fact, even if it is ten thousand tons, Su Han’s current mining capacity is not unacceptable.

But the problem now is that this is only a 500,000-ton Jiaolong-class warship.

If you create a mothership of tens of millions of tons in the future.

Wouldn't it take 270,000 tons of helium three to push it to 50% of the speed of light?

270,000 tons of helium three.

Where are you going to find so many helium threes?

The key is that it takes 270,000 tons to slow down.

Together, it takes 540,000 tons of helium three.

Too exaggerated!

Su Han thought of this: "By the way, Shenlong! If the spacecraft is pushed to 10% of the speed of light, how much fuel is needed?"

Shenlong said: "About ninety tons!"

Su Han was stunned when he heard this! He said, "How could it be so much different?"

Shenlong said: "The faster the speed, the greater the mass, the greater the energy required."

Su Han thought about it.

Ten percent of the speed of light is undoubtedly the most cost-effective speed.

Although the mothership released to tens of millions of tons also requires nearly 10,000 tons of helium three, it is still within its own tolerance.

At worst, you can mine both the Moon and the Helium on Mercury.

I believe I will collect more than 100,000 tons of helium three.

Enough of your own fleet to accelerate and slow down once or twice.

Su Han suddenly thought of something and said, "By the way! Accelerate to 10% of the speed of light. How long will it take?"

Shenlong said: "It will take about ninety years!"
