Ion engines?

The corners of Ye Fan's eyes twitched slightly, this kind of thing appeared, this is the engine on the spaceship.

However, the efficiency of this engine seems to be countless times better than that of the spaceship.

At least in terms of speed.

The speed has reached almost 152,792,458 m/s.

That's half the speed of light.

One engine is half, what about two?

Wouldn't it be possible to multiply the velocity of a mass by two?

The principle of the ion engine is: through the photoelectric conversion device to convert the solar energy into electrical energy, and then through the structural design to make the electric energy produce an electromagnetic field, the working medium is ionized at high temperature, the electrons run out of the atoms or molecules, the atoms or molecules that lose the electrons are positively charged, and the escaped electrons are negatively charged, and they are neutral in general, which forms a plasma; Neutral plasma is electrically conductive and interacts with magnetic field energy, and the force that generates acceleration can be obtained by electromagnetic induction. In a nutshell, it is the principle of using the electromagnetic field induced by solar energy to generate the Lorentz force on the current-carrying plasma, so that the working medium in the neutral plasma state is accelerated to generate thrust.

What is this for?

Ye Fan looked down and found that there was no technology.

That's it?

That's it?

Will this solve the solar problem?

Do you want to build a spaceship for yourself, a super huge spaceship and get out of here?

Ye Fan had countless questions.

"What Mr. Ye said is not wrong, if according to the data given by Mr. Ye, if the earth only has 30 years of life, what can we do to save ourselves in these 30 years? Even if you use a spaceship, you can't do without the solar system, so what? ”

"Isn't it, inseparable from the solar system, it's still a dead end."

"Building a dungeon is time-consuming and labor-intensive, how to build it?"

Controversy arose at the scene.

Each party has its own ideas and opinions.

But their thoughts and opinions are all based on Ye Fan's deduction results.

It's impossible to find the latest research options.

Ye Fan opened his eyes, looked at the chaotic scene, frowned, and then said in an astonishing voice: "Everyone, if I have a product, I can build a dungeon within three years, or even in less time, and each dungeon can accommodate up to 10 million people!" ”

Rumble!

Hearing this, the scene boiled even more.

Tens of millions?

Is this possible.

With tens of millions of people, it is equivalent to a second- or third-tier city.

How big is a dungeon that accommodates so many people? Can it be completed in three years?

Everyone looked at Ye Fan in disbelief.

They couldn't accept it in their hearts, although this kind of words came out of Ye Fan's mouth, they still couldn't believe it.

If someone else says it, then they treat it as a joke.

But Ye Fan said it, even if he didn't believe it, he had to maintain respect.

When Professor Ma heard Ye Fan's words, he was also stunned on the spot, looked at Ye Fan with a shocked face, and said intermittently: "Really? Can you build a 10-million-level dungeon in three years? ”

"In this regard..."

Before Professor Ma could continue to speak, Ye Fan directly interrupted and said: "It's not a difficult thing, I have a super diamond suction spray bit technology, the drill bit is thirty square meters, per hour, it can dig down three hundred meters, and the suction spray bit has a spraying function, while drilling the ground, it can spray H agent around and solidify the underground passage!" ”

Quiet..

The scene fell silent for a moment.

One by one, they grew their mouths and looked at Ye Fan dumbfounded.

Three hundred meters can be excavated in one hour.

Even the world's top, the best drill bit, can't reach this point, right?

"Brother Ye, is this all true?" Professor Ma stood aside and asked excitedly.

Ye Fan did not speak, but nodded very solemnly.

Wow.

The scene boiled directly.

Quite a few people jerked to their feet.

If it was true, if there was this equipment, wouldn't it be possible to build a dungeon in a year or two?

It's no joke.

It's true!

According to the deduction results given by Ye Fan, the dungeon must be built, they think so, and X Zhibrain also says so.

Dungeons, it has to be built.

Because only a dungeon can survive a flare, and only an ice age can be avoided.

When everyone was boiling, Ye Fan left and returned to his lounge.

Professor Ma still wanted to follow, because Ye Fan had brought him most of the surprises, not so much fright, he needed to absorb it, and he needed to ask more to know more.

But apparently Ye Fan seemed to be a little tired.

Directly refused.

But when Ye Fan closed the door, he said that when he came out, he would give them the technology about drill bits.

Professor Ma was relieved.

When Ye Fan entered the room, Professor Ma also immediately collected all the news and sent it to the official.

If it is really as Ye Fan said, then it is necessary to build a dungeon, and to build a dungeon, you must also get official help, without official help, then they are also blind.

Let's talk.

Is there only one region on earth?

Ye Fan, who returned to the room, told X Zhibrain all the three-point skills he had obtained.

After getting the technical details, X Zhi Brain began to deduce and calculate.

"Boss, about the first drill bit, it should be used to dig dungeons!"

"The second technology, Bai Jing, have you forgotten boss, Bai Jing has us, and there are a lot of them, hundreds of warehouses are already full!"

Oh?

Hearing X's response, Ye Fan was slightly stunned.

Hundreds of warehouses are filled?

What is that white crystal?

Isn't that right?

Ye Fan thought of one thing, that is, the haze absorber absorbs all the haze, and finally condenses into white crystal-like things, as if it is white jade, Ye Fan was still thinking about what these things are for, but X Zhibrain did not tell him, now it seems that it is white crystal.

Also.

Baijing absorbs haze, and what is haze?

A large amount of dust, as well as various radioactive toxic substances condensed, plus compression to form white crystals.

If according to the system, a white crystal can reach the annual power consumption of a first-tier city, it is too terrifying.

If you didn't have an energy converter, you wouldn't know that this kind of thing could release energy for the rest of your life, right?

For example, the ancient people, they didn't disarm technology, can he know water and fire in this life, can he compose steam? Can steam have power?

Can they know that black charcoal can brush their teeth and wash their hair?

Can they know this?

Can they know that a certain ore contains a lot of elements?

I don't know.

Just like Ye Fan, while he didn't come into contact with this higher-level technology, he didn't know that Bai Jing was able to release energy.
