Ella's method is indeed very good. Yan Xia actually thought that the Olive Branch Civilization had mastered some super gravitational energy technology, but in the end they found that they had overestimated the Olive Branch Civilization. The Olive Branch Civilization itself still used the more traditional way of converting gravitational energy into mechanical energy, but the utilization efficiency was very high. There is no essential difference between it and the gravitational energy device that Yan Xia had imagined in Rigel. It's just that it's not a piston structure that is moving, but the entire star city. The entire star city of the Olive Branch Civilization can rely on gravity to complete movement. The interior of the entire star city is actually a structure similar to a flat wheel. It uses this structure to achieve a Stirling engine-like mode, that is, using gravity and cold and heat to complete the continuous circulation of an object. The material in this "flat wheel" will change its gravity due to the alternation of hot and cold and the interference of some electromagnetic forces, or change the degree to which it is affected by gravity. When this material is heated, it will not be easily affected by gravity, and may even expand. Then the material on the other side that is easily affected by gravity will fall towards one place due to gravity. After falling to the lower end, it will be heated and continuously push the material in front to move. When Yan Xia saw this thing, he even thought that this thing was a heat engine, and gravity was only slightly involved. But in fact, there is still a difference. Gravity can make the energy consumed in this process lower. The Stirling engine requires hot and cold changes, so it must require energy to produce hot and cold changes. However, the star city of the Olive Branch civilization is different. It collects the energy of the star itself for heating. If it is viewed as a heat engine, its energy conversion rate is 100%. This is why this thing can continuously supply energy to the Olive Branch civilization. It is even more efficient than directly mining stars.
This "flat wheel" is so big that the energy used to move it even 1 meter is quite terrifying in terms of astronomical units. Naturally, it is quite easy to convert the mechanical energy it produces into the most common electromagnetic energy in the universe. Having electromagnetic energy means having the other three energies, because the four fundamental forces have been unified. Of course, as mentioned before, the Olive Branch civilization has not yet achieved the technology to directly convert gravity into electromagnetic force, so this conversion is also limited. "I don't deny that my civilization's way of making energy is very backward, it's just a huge heat engine." Zhuo admitted this. Because the Olive Branch civilization entered the Gass era too early, many technologies could not be developed. The progress of energy technology is very difficult, so Gass had to gradually make the star city bigger and bigger. The bigger the star city, the larger the volume of the heat engine, and the greater the mechanical energy generated. Gravity can make the heat engine itself have inertia, and inertia and the characteristics of the material inside the heat engine can gradually increase the speed of the heat engine instead of stabilizing. Now the rotation speed of the "flat wheels" in each heat engine in the Olive Branch Civilization is extremely terrifying, and may even exceed one tenth of the speed of light, which is why it can create and maintain a level civilization. Of course, there are more problems, such as centripetal force, centrifugal force, etc., and the Olive Branch Civilization is the top in this technology. "This is because although other methods are very advanced, the quantity can never reach the standard, right?" Yan Xia understands the choice of the Olive Branch Civilization. For example, you can use the decay or fusion fission of dark matter to generate energy, but there are only 10,000 devices, and each of them contains only a few grams of dark matter. Although such energy utilization is very advanced in terms of technology, the energy produced is too little, unless you have countless dark energy and tens of billions of such devices. But then cost is the primary consideration. So now another question in Yan Xia's mind has been answered, that is, why the Olive Branch Civilization is so concentrated, rather than widely distributed in the star field controlled by itself like the Civilization Federation. All the resources of the Olive Branch Civilization have been consumed in the construction of these star cities, which are also large heat engines. "So now that several star cities have been destroyed, our energy production has also dropped, and we can only be a level civilization." Yan Xia said. Zhu nodded: "This is indeed a pity." "The reason why the Olive Branch Civilization has progressed so slowly is also because the energy production method is not advanced enough. This is a shackle." "But fortunately, the Federation has developed a more advanced energy production method, right?" Indeed, all of this is Yan Xia's now.
There is no so-called Olive Branch Civilization anymore, and all of this belongs to the Civilization Federation. "Zhu, do you want the Olive Branch Civilization life to continue to maintain the status quo, or become life?" Now the number of lives in the Civilization Federation has become extremely small because of Gais's previous "Human Massacre Plan", but fortunately, biological organisms can be created, and instead of starting from scratch, it is better to convert the billions of lives of the Olive Branch Civilization into life. This is Yan Xia's next plan. Zhu thought about it, and then gave a high emotional intelligence answer: "This is not something I can decide, but it depends on them." "I think we can make a plan to allow the lives of the Olive Branch Civilization to freely choose to transform into humans. Of course, all this is irreversible. I know you will control the life span of life to achieve the rotation of life itself and the health of the civilization." But there is a problem. "Then what will happen to the remaining mechanical lives? It seems a bit unfair to continue to stay in the Federation." When Yan Xia looked at him with a smile, he instantly understood what Yan Xia wanted to say. "Let's establish a star country and let this star country depend on the Federation to exist." In fact, he regretted it as soon as he said it, because Yan Xia obviously wanted him to be the king of this star country. "This is indeed the best." "I'll leave it to you, Xu." "After completing the transformation of life, these lives will begin to migrate. The five star fields of Tiancang, the Silk Road Star Field, the Water Committee Star Field, the Rigel Star Field and the Orion Nebula Star Field, covering a range of 1,500 light years, will become the new territory of the Civilization Federation." "To perfectly control such a large star field, we all need to work hard." This is a big plan. At least in Yan Xia's opinion, another 50,000 years will pass in this plan. But... "It must be exciting!" Xu said. "Sure!"
