    Qingshan scanned the electromagnetic environment of Dawu Star and reported: "The principle of large-scale wireless power transmission is similar to that of shortwave, which transmits electromagnetic waves through the ionosphere. However, the power of wireless power transmission is much greater than that of a radio station, so the radio  The signal cannot be received.¡± ¡°Any good suggestions?¡± Gu Yun was a little bit dumbfounded when he heard this principle. He didn¡¯t expect that high-tech things would affect the radio, and he had introduced the radio, and now he gave it up as a fashion.  morning.  After comparing the data, Qingshan suggested: "After the satellite communication system is built, broadcast programs can be sent through it, and the original broadcast sending method can be completely eliminated. If the broadcasts in these days are very important, the power generation can be shut down  station, first use a temporary power supply center, let the small intelligent construction center direct 100 engineering robots to concentrate on construction, and prioritize the construction of the satellite communication system. The three projects of the intelligent control center, large storage center, and ground monitoring center will be constructed in parallel. The construction period is approximately  It¡¯s 5 days!¡± ¡°Five days! Okay, I can still afford to waste this time, so let¡¯s focus on building the satellite communication system!¡± Gu Yun is not only thinking about the radio station, but also the Ten Route Army who are going out.  Due to interference, if they cannot receive news from Beijing and Luozhou City, there may be some trouble.  Qingshan then reported: "Then I will also prepare to launch satellites. 108 satellites need to be launched in three times. They need to escape the gravity of the planet from the atmosphere to space, and return smoothly from space to the atmosphere. This requires a lot of energy and may consume the spacecraft.  90% of the energy!" "90%, I'll just generate electricity for you after the satellite communication system is completed!" Gu Yun can still afford this loss, "Yes, Master!" Qingshan was silent after finishing the report.  It seems to save energy.  After Gu Yun confessed to Liu Ruyan, he immediately took the Qingshan spacecraft to fly to the nuclear power plant.  After shutting down the reactor, he flew to the far north.  After moving the temporary power supply center and small intelligent construction center to Guliu Villa.  He also transferred 75 engineering robots from Guliu Villa, and then asked them to start the construction of the satellite communication system.  The intelligent control center of the satellite communication system was built first because it is mostly a complete set of equipment, unlike large storage centers that have many parts and are troublesome to assemble.  The construction of the control center took only two days.  One day later, the ground monitoring center was also completed, and Gu Yun immediately asked the Qingshan Intelligent Brain to temporarily take over the control center and monitoring center.  At the same time, preparations are being made for the launch of 108 satellites.  Finally, after another two days of intense construction, the large storage center was completed and the satellite could be launched for testing.  Gu Yun took the Qingshan spacecraft and set off with 36 small satellites.  Gu Yun suddenly felt a strong inertia pressing his body to the point where it was almost difficult to breathe. It turned out that the Qingshan had accelerated to the first cosmic speed that was enough to escape the gravitational range of the Dawu Star.  And automatically opened the energy shield.  After accelerating, Qingshan gradually stabilized and flew toward low-Earth orbit at a constant speed.  Gu Yun asked curiously: "Qingshan, was it entering and exiting the atmosphere just now? If my body is not strong enough, wouldn't it be crushed?" Qingshan's brain seemed to have recovered from silence and replied: "  Yes, Master, there is an acceleration phase when flying out of the atmosphere, and there is also a deceleration phase when entering the atmosphere. This will produce huge inertia. After the spacecraft is reduced, anyone who has been injected with the primary gene enhancement agent can withstand this pressure.  No additional measures are needed. Anyone who owns a spaceship will be told this. This is one of the common senses in entering and exiting the atmosphere. "Gu Yunxin said that he was too successful in pretending to be an alien, but Roy ignored it.  The spaceship may carry ordinary people.  So he asked: "Are there any measures on the spacecraft that ordinary people can adapt to?" "Yes, there are 16 isolation cabins in a room on the first floor, which can overcome the strong inertia when entering and exiting the atmosphere. The space suit on the ship also has to reduce  "Does the master need it?" "No!" Gu Yun felt relieved, "How much energy is left?" "The spacecraft will consume 15% of its energy when it reaches the predetermined orbit, and then the energy of the spacecraft will be 73%.  %!" "73%? How many times can it jump in space? I remember that there is space jumping technology in the movie, right?" "But it can only be used after leaving the atmosphere?"  As a reminder, space jumps use a separate dark matter engine. This spacecraft can jump 7 to 10 times. After that, the dark matter engine must be purchased as the most advanced facility of the spacecraft, accounting for two-thirds of the cost of the entire spacecraft.  , and the space jump places a huge load on it, and it can only be used safely within 100 times. " "Is that so?" Gu Yun secretly scolded the profiteer.?I have to sigh, if it were me, I would also make things with extremely short lifespans for sale. Otherwise, if users don't update them, where will the profits come from?  It seems that things for civilian use are really not good. In the future, we have to find a way to get a military spacecraft. We cannot get it for large warships, but we must get it for small reconnaissance spacecraft and scientific research spacecraft!  The Qingshan No. 1 Intellectual Brain gave an urgent explanation: "Space jumping is one of the basic functions of a spaceship. The universe is really too big. Even if you can fly at the speed of light, flying from one star galaxy to another star galaxy, at least  It often takes decades. Without space jumping technology, interstellar navigation is impossible. What's more, the spacecraft cannot reach the speed of light at all, because the gravity of the planet, the inertia of the spacecraft and other things are far beyond imagination when running at high speed.  There is no known material that can be used normally in that state. "Gu Yun then asked: "Why does the spacecraft only jump in low-Earth orbit?" "Because low-Earth orbit is in a state of weightlessness and the gravitational interference is relatively small.  It is small and has one of the basic conditions for a space jump. Of course, you can jump after spending a lot of energy to accelerate to the second cosmic speed and escape from the star galaxy where the administrative star is located, but it is not necessary." Gu Yunxin said no wonder in the film.  The space battles that appear in the game are all in the low-Earth orbit of the administrative star, which is no more than a star galaxy at most. It seems that the low-Earth orbit and star galaxy are equipped with gravitational interference facilities, and the enemy's spaceships can only jump to the vicinity of the star galaxy at most.  , and then had to adopt a flight state due to gravitational interference, and entering low-Earth orbit would be considered as an enemy.  Gu Yun then asked: "Jumping technology costs a lot of energy, right? Does it cost more energy to jump to a farther place?" "Space jumping includes two steps: initiating the jump program and performing the space jump. Among them, initiating the jump program requires  The energy consumed is different. The farther away, the more energy is consumed, and the closer, the less energy is consumed. However, the energy consumed by the space jump itself is roughly the same, less than 1% to 20%.  !" Qingshanhao Zhinao gave an answer that made Gu Yun unbelievable.
