Chapter 720： : What is Bai Jing! Be sure!

Ion engine?

Ye Fan's eyes twitched slightly, and such things appeared. This is the engine on the spacecraft.

However, the efficiency of this engine seems to be many times better than the spacecraft.

At least in terms of speed.

The speed has reached nearly 152,792,458 meters seconds.

That is half the speed of light.

One engine is half, what about those two engines?

Wouldn't it be possible to multiply a qualitative speed by 2?

The principle of the ion engine is: the solar energy is converted into electrical energy through the photoelectric conversion device, and then the electrical energy is generated by the structural design. The working medium is ionized at high temperature, the electrons run out of the atoms or molecules, and the atoms or molecular bands of the electrons are lost. Positively charged, the escaping electrons are negatively charged, they are generally neutral, which forms a plasma; the neutral plasma has conductivity, interacts with the magnetic field energy, and can generate acceleration by electromagnetic induction Of force. In summary, the principle of using the electromagnetic field induced by solar energy to generate Lorentz force on the current-carrying plasma accelerates the working medium in a neutral plasma state to generate thrust.

What is this for?

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

It's over?

this one?

Can this solve the sun problem?

Do you want yourself to build a spaceship, the super huge spaceship left here, right?

Ye Fan with countless doubts.

"Mr. Ye is right. According to the data given by Mr. Ye, if the earth has only 30 years of life left, what can we do to save ourselves in these 30 years? Even if we use a spaceship, What if the solar system is not turned on? "

"Isn't it, without the solar system, it is still a dead end."

"It takes time and effort to build an underground city, how to build it?"

The scene was controversial.

All parties have their own ideas and opinions.

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

It is impossible to find the latest research plan.

Ye Fan opened his eyes, looked at the chaotic scene, frowned, and then said surprisingly: "You, if I have a product, can I build a dungeon in three years or less? , The number of people that every underground city can accommodate is as high as ten million! "

boom!

Hearing this, the scene became more boiling.

Ten million?

is it possible.

Ten thousand people, it is equivalent to a second- or third-tier city.

How big is the 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 they said it from Ye Fan's mouth, they couldn't believe it.

If it is spoken by other populations, then they should listen to it as a joke.

But Ye Fan said it out of her mouth, even if you do n’t believe it, you still have to respect it.

When Professor Ma heard Ye Fan's words, he was stunned on the spot, looking at Ye Fan with a shocked expression: "Really? Can you build a dungeon of tens of millions in three years?"

"In this regard ..."

Before Professor Ma continued to speak, Ye Fan directly opened the mouth and said: "This is not difficult, I have a super diamond suction jet drill technology, the drill bit is 30 square meters, and can be digging down 300 meters per hour And, the suction spray bit has a spray function, while drilling the ground, you can spray the H agent around to solidify the underground passage! "

Jing ..

The scene instantly fell into silence.

One by one, his mouth grew wide and he stared at Ye Fan with a stunned look.

It can dig 300 meters in one hour.

Even if it is the top and best drill bit in the world, it is impossible to achieve this step?

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

Ye Fan did not speak, but nodded very solemnly.

Wow.

The scene boiled directly.

Many people stood up violently.

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

This is no joke.

This is real!

According to the deduction results given by Ye Fan, the underground city must be built, they think so, X Zhinao said so.

The underground city must be built.

Because only dungeons can survive flares and ice age.

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

Professor Ma also wanted to follow, because Ye Fan brought him most of the surprises, not so much as a shock, he needed to absorb, and need to ask more to know more.

But obviously Ye Fan seemed a little tired.

Directly refused.

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

Professor Ma was relieved.

When Ye Fan entered the room, Professor Ma immediately sent all these messages back to the official.

If it is true as Ye Fan said, then you must build an underground city, and to build an underground city, you must also get official help. Without official help, then they are also blind.

Let's talk about it.

Is there only one region on the earth?

Back to the room, Ye Fan ~ www.novelhall.com ~ told X Zhinao the whole three-point technique he had obtained.

After X Zhinao got the technical details, he started to calculate.

"Boss, about the first drill bit, that should be used for digging the dungeon!"

"The second technology, Bai Jing, do you forget the boss, Bai Jing we have, and there are many, hundreds of warehouses are full!"

Oh?

Hearing X Zhinao's response, Ye Fan froze slightly.

Are they filled with hundreds of warehouses?

What is Bai Jing?

Could it be that!

Ye Fan thought of something, that is, the haze absorber absorbed all the haze, and finally condensed into white crystal-like things, as if it were white jade. X Zhinao didn't tell him, now it seems that it is Bai Jing.

Too.

Bai Jing absorbs smog, and what is smog?

A large amount of dust, and a variety of radioactive toxic substances condensed, and the white crystals formed by compression.

If according to the system, a white crystal can reach the power consumption of a first-tier city for one year, that's too scary.

If there is no energy converter, don't you know that this kind of thing can release energy in your whole life?

Just like the ancients, they didn't release technology, can he know water and fire in his life, and can make up 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?

do not know.

Just like Ye Fan, he was not exposed to this higher-level technology, and he did not know that Bai Jing could release energy.
