"Of course, this track is called Tongtian Tower. The building next to it is a controlled nuclear fusion reactor, and it is taken the stellar imitation route. It is said that power has been successfully generated last month. In the future, not only can the electricity consumption of Tongtian Tower be supplied, but the electricity consumption in the entire Antania will also be solved. ▲∴”

Wang Dan raised his glasses and said that although his myopia had been completely cured after joining Xinglian, this habit could not be changed.

The other four people called Pei repeatedly, called out relevant information, and figured out what the imitation star device route was.

The progress of controlled nuclear fusion is the most far-reaching technological breakthrough on the eve of the Great Navigation, but strictly speaking, it is just a by-product of the advancement of ion engine technology.

Relying on Xia Ming's system of cosmic constant conversion equations brought by the star gate, humans have mastered the new dimensions of calculating plasma movement, which makes the ion engine a universal driving force for humans to visit the "inner sea" of the solar system, and it also overcomes the biggest difficulty of controlled nuclear fusion.

To apply systems of equations to controllable nuclear fusion, another major problem needs to be overcome, that is, to increase the computing power by tens of thousands of times. Based on the 10 billion times per second of the "Tianhe x" in China, it must be increased to 100 trillion times, which is to the power of 22 of 1 by 10. Using the old Chinese number method, that is 100 Gai.

This level cannot be achieved by simply stacking more chips for parallel computing. Lin Cheng initially asked Qian Yan to help him to cope with the initial testing stage, and then used a primary optical brain made of gallium nitride semiconductor.

The computing problem was solved, and Iii used the optical brain architecture to solve the silicon carbide neuron chip, and intelligent control was further improved. At this time, the controllable nuclear fusion finally opened the door to humans.

Star Alliance's controlled nuclear fusion does not follow the inertial constraints and tokamak routes. The former still does not solve the problem of reaction vessels. The latter has huge risks because of using plasma as the other level of the magnetic field. Once the magnetic field ends unexpectedly, a huge disaster will occur.

The stellar imitator route is the most theoretically safest and reliable. Its technical principle is to imitate the nuclear fusion of stars, but to replace the gravitational constraints of stars with magnetic field constraints. Only this route is considered a real "artificial sun". Like an ion engine, the two poles of the magnetic field are external and do not require plasma to provide magnetic poles.

Before, neither China, the United States nor Europe took this route because the coil design and layout of external magnetic fields needed to be extremely accurate and exquisite, and the requirements for engineering technology were too high. Only countries like Germany and Japan had made attempts in precision engineering.

But now, the intelligent magnetic field control array of ion engines provides a solid foundation for the stellar imitation route. Coupled with significantly improved supercomputing and intelligent technology, controllable nuclear fusion finally played a practical movement on November 17, 2022.

Dongfang Sheng, the host of controlled nuclear fusion research, won the second Star Gate Award with his team, the first one being the improvement of the ion engine.

The Star Gate Award is a "human-machine collaboration" award specially set up after the establishment of the Star Gate Alliance to promote the application of Gei in scientific research. As long as the technological progress is involved in Gei, you can run for the election. Ten items are selected every year, regardless of the scientific field. After this award was launched, the Nobel Prize began to decline, of course this is an off-topic topic.

The impact of controllable nuclear fusion on humans is undoubtedly the most important, but it does not make the world soar as soon as it succeeds, nor does it mean that energy costs zero. Scientists are still studying how to more safely and efficiently draw out the electricity emitted from plasma in the reactor. The preparation and storage process of deuterium and tritium also needs to be further improved, so Starlink has not reported it extensively.

More importantly, the current nuclear fusion is still the first generation, which is the reaction of deuterium and tritium, and neutron radiation also requires strict protective measures. It is not until the second generation of nuclear fusion, that is, the reaction of deuterium and helium 3, that is, the reaction of neutron radiation, the reaction of the third generation of nuclear fusion, the reaction of helium 3 and helium 3 is the truly ideal pollution-free nuclear fusion.

Now that humans have just entered the threshold of the first generation of nuclear fusion, it will be another theoretical fifty years before they can develop to the third generation.

"When we complete the training, will we launch into the sky from this tower of heaven?"

"Be good, how many times the force you have to withstand? Why do I think it's not reliable at all?"

"When I think of riding a rocket into the sky, my legs became weak, not to mention being shot directly into the sky by this electromagnetic slingshot."

"Do you know some technology? What's the difference between this and catapulting aircraft on an aircraft carrier?"

The five people's attention quickly changed from controlled nuclear fusion to the "Tiantian Tower" in front of them. The controllable nuclear fusion reactor belongs to the newly established Star Nuclear Energy Company under Xinglian, and this Tower of Sky is the asset of Kunpeng Company.

For Xia Ming's Star Gate Alliance and the opportunities and challenges facing mankind at present, the most urgent issue is not controllable nuclear fusion, but an economically reliable "space springboard".

If you still use rockets to launch spacecraft or cargo, you will not wait until the star gate of Zhishen Star collapses, and governments will be bankrupt.

The launch cost of the rocket is still at $10,000 per kilogram. Even if relying on intelligent control and ion engines, the rocket recycling technology has matured and the cost will be reduced by at most half. Other costs, such as the difficulty of mass manufacturing of rockets, and the launch window is limited by weather, etc., cannot be reduced.

Kunpeng Company, chaired by Lou Xinghai, regards electromagnetic orbit emission as a new generation of launch technology. Although General Group of the United States has made progress in this regard by relying on the technical accumulation of long-spike electromagnetic railguns, it is still not as good as Kunpeng Company's progress. After all, with Qian Yanding's strong assistance, it has support from ion engines, controlled nuclear fusion, optical brain technology and new generation semiconductors.

In principle, the technology of electromagnetic track launch is mature enough. The nail rail gun can accelerate 500 kilograms of tungsten rods to more than 30 times the speed of sound. In order to convert it to nearly 10 kilometers per second, it can overcome gravity.

The main problem that hinders the emission of electromagnetic tracks is circuits and materials. The acceleration during emission of electromagnetic tracks is as high as tens of thousands of g. Not to mention ordinary silicon-based semiconductors, even gallium nitride or silicon carbide cannot withstand it. At such a high g force, precision components will break, the chamber will be distorted, and it will not work normally.

If there is no control circuit and no engine for attitude adjustment, the only thing that can be shot into space is the shell, and it cannot control where it flies, which makes no sense.

In terms of semiconductors and circuits, graphene is one direction, but this direction has just emerged. In terms of materials and components, it is a completely new topic. In short, there is still a long way to go to launch satellites or spacecraft using electromagnetic orbits.

But now Star Leagues, and even humans, can't wait.

Lou Xinghai came up with two ideas. One was to learn from Xia Ming's feat of using the Scavenger to control the earth's orbit and deploy several "cargo docking systems" on a certain layer of the earth's orbit. In fact, it is an intelligently controlled space trailer. Through accurate calculations, the electromagnetic track directly launches uncontrolled and unpowered cargo to a certain layer of near-Earth orbit, and then the nearby space trailer will receive the cargo.

The idea is very feasible, and the unoc (Space Council) quickly approved the resolution to open the corresponding earth orbit into a "connection zone". When this technology matures, the launch cost will be reduced to less than $10 per kilogram, which will untie the rope loop that strangles the necks of governments.

Lou Xinghai's other idea was a bit terrifying. He proposed that the existing aerospace circuits and materials only need to be strengthened and improved, and the thrust of the ion engine can be further improved, the electromagnetic orbit can be used to launch manned spacecraft.

Lou Xinghai said: "It's better to take this as a plane ejection on an aircraft carrier. The thrust of the ion engine, coupled with the ejection of the electromagnetic orbit, can allow the spacecraft to enter the earth's orbit within the overload range allowed by human bodies and precision components."

The cost of this plan is much more expensive than launching cargo directly into space with electromagnetic orbits, about $50 to $100 per kilogram, but it is much cheaper than launching manned spacecraft with rockets. It should be very attractive for the Unoc, which plans to transport more people to space.

If safety is not considered...

Unoc's reply was waiting for further technical verification by Kunpeng Company. Musk and Bezos were very active. Their company first started to work with this idea. Of course, the initial biological experiment was not ideal. Poor that several orangutans became victims of humans' pioneering a new era of aerospace, which made the animal welfare elements shout why not use people to do experiments first...

Wang Dan said: "We will go to heaven in one month. At that time, the electromagnetic projectile manned spacecraft should not have matured."

"Time flies so fast. It's been three months since we've arrived here," Wu Kang sighed and turned back. Antania was no longer the large construction site they had just arrived at. High buildings rose up, and on the crisscrossing roads, rail cars and trams kept shuttled.

Andaoyuan urged: "Let's go, the family is settled, we have to do our best to get good results in the graduation exam!"

The five of them had just returned to Antania after taking a week off and began their final intensive training to prepare for their trip to Zhishenxing.

Although they are all worried about fearing this and that, if the graduation exam is not good and they are unable to choose to go to heaven, it will be a great failure for them.

Apart from personal face, what I fear most is that I can't keep up with her footsteps.

At this moment, a short-haired woman flashed in everyone's heart, bright, healthy, vigorous, chasing the future without stopping.

Five people got on a driverless tram and soon entered Antania, which had already appeared in the prototype of the city.

Antania was built almost at a barracks speed. Until now, in addition to the Xu Artificial Intelligence Research Institute, dozens of corporate headquarters and research institutions have moved here.
