Showdown, this is the pirate chat group

They subconsciously wanted to ask Qiao Lin what it was, but then they thought that this should be something everyone in Qiao Lin's world knew.

If they ask this question, they will be exposed.

At this time, the only option was to let her take action.

Sure enough, in the hope of everyone, Hiwa Kozuki, who has a self-awareness of a tool man, asked his own question in the group.

Lurker:"What is that thing called a satellite?"

Qiao Mulinsen:"Man-made satellite, you can also call it an unmanned spacecraft that orbits the earth in space. Let me introduce it to you in the most popular terms. , this thing is a machine made by humans and sent to space beyond the planet where we live.

It can complete some physical experiments in space or complete some tasks such as communications, military, meteorology, resources, and interstellar exploration."

Qiao Lin His words immediately confused everyone in the group.

Space orbit?

Outer space?

Interstellar exploration?

What are you talking about?

Even Robin and Franky were a little confused. They probably understood that what Qiao Lin was talking about was that this thing was probably going to be sent to places other than the planet.

Robin is proficient in history, and Franky has learned the lunar technology left by Vegapunk. They both know that they live in a huge sphere, and there are other planets outside this sphere.

But they don’t know what exactly is outside the planet.

This machine seems to be placed outside the planet in a place called space to perform some very important work, but they don't understand what it is.

Although they did not understand these things, there was one thing they did understand.

That is this so-called artificial satellite. It is flying in the air, and it is not just in the ordinary air, but in a place very high above the ground called outer space!

Lurker:"What? What? Space, interstellar exploration... What are these things, I'm very curious."

Sure enough, these things are still too vague for them... Qiao Lin thought.

Although the technology in the One Piece world has airdrops from Moon Technology, the overall technological level has not improved dramatically. It is basically still at the level of the steam age. Even electricity has not been popularized. Kerosene lamps and candles are still used as Lighting facilities.

It is too fast for them in this era to understand these things.

Then he found a picture of atmospheric vertical layers and sent it to the group.

Qiao Mulinsen:"Here I will give you a brief introduction to science and take care of you, a junior high school student. This is the planet we live on. The reason why there is life on this planet is because the atmosphere at that time removed those harmful substances in the sun. Part of the radiation is absorbed, otherwise people will be killed directly if they are directly exposed to the sun.

The atmosphere is divided into several regions, the troposphere, stratosphere, mesosphere, warm layer and exosphere, with the exosphere extending to the surface A thousand kilometers away, and beyond the exosphere is the so-called interstellar space, which is outer space.

Artificial satellites are completed by sending the spacecraft to this area and letting it fly around the planet according to a predetermined orbit. Corresponding work.

For example, communication. The world of One Piece has magical creatures like telephone bugs, so although it has not developed technology, it can still be used to achieve long-distance information exchange.

But our world does not have such creatures, so people invented the telephone , this kind of machine that relies purely on electronic components to achieve long-distance calls, the mobile phone transmits the signal to the satellite. The satellite then relays the signal to the target you want to contact, and cooperates with the base station on the ground through multiple satellites. This communication The network can cover the entire planet, allowing people in every corner to communicate with people in other places.

With the development of communication technology, mobile phones can not only be used for calls, but also for video, live broadcast and other means. This is already It is an indispensable application in people's lives.

The phone bug in the One Piece world is designed based on this. However, because the technological level of the Pirate World is very low, it is basically impossible for them to create satellites, so they can only give them They cheated and designed magical creatures like telephone bugs to replace these complex principles."

Although they still didn't quite understand the principles of cooperation between satellites and base stations mentioned by Qiao Lin, they were greatly impressed by the things they could understand. Shock.

How can we achieve this by sending something to space a thousand kilometers above the ground?

I didn't expect that the phone bug would appear like this. The humans in that world were so terrible that they could create such a thing.

Qiao Mulinsen:"As for the military, the satellite is directly overlooking the earth's surface at an altitude of a thousand kilometers away, with an unobstructed view. It can detect the situation on the ground and then take photos and send them back to help commanders grasp battlefield information. In addition, In addition, previous communications can also be used in the military to command battles in real time, and many weapons also rely on it to operate.

Meteorological satellites can predict weather conditions by analyzing clouds.

Resource satellites use Special means are used to detect strata, and by analyzing the detected information, the distribution of resources under the ground can be easily obtained, eliminating the need for hard and troublesome field surveys."

If they had been able to create something for people in this world before, Words that amaze you with a communication device that is better than a telephone bug.

What Qiao Lin was talking about now about the application of artificial satellites made their minds surge like waves, and their shock was palpable.

Logically speaking, the specific situation on the ground should not be visible at all from a thousand kilometers away, but they can actually use it to detect the situation on the surface. Doesn't this mean that no matter where they are, they are within their sight?.

What's even more frightening is that if you apply this to war, then every move of the enemy will be within sight.

Dorag is now very fortunate that such technology has not appeared in the hands of the World Government, otherwise the revolutionary army would really have no choice but to hide underground, or else they would have nowhere to escape.

The application of weather satellites also made Dolag excited, which meant that the unpredictable weather during their voyage at sea could be made predictable.

What Dorag desires most is the resource satellite, which can directly detect the distribution of resources around the world. Then he can mine wherever he wants. It feels good to think about it.

"Technology?"Dorag breathed a deep sigh of relief,"It's really terrifying. I didn't expect humans to be able to do this."

A fiery look flashed in his eyes. It would be great if the revolutionary army could also obtain such a treasure.
