For Cao Chuan, economic development would have been an interesting thing 100 years ago, but in fact, even with the help of digital cities to make mayors as simple and intuitive as playing a simulation management game, as the size of East Galaxy becomes more and more perverted, such a thing will inevitably become torture.

Imagine that if you want to develop a planet, the places that may be affected have changed from a few places earlier to hundreds of places, and most importantly, these factors are random and uncertain, which is really a headache.

Presumably, many regular employees who are still in the position of mayor will feel the same way, so Cao Chuan did not give instructions on what to do, but directly delegated the goal to multiple cities, let the mayors worry about themselves, put forward plans for themselves, and what he cared about was the total economy.

Then he has time to solve a big problem, which is the real third-generation ship.

Introducing the third generation of ships and ushering them into a new era! An attractive slogan.

The third-generation spacecraft has an irreplaceable temptation for human beings, and the production and sales of expensive star-rated spaceships have skyrocketed in recent years, which can prove what the third-generation spacecraft means to human civilization.

The era of planet development is not the era of spaceships and starships? The importance of spacecraft to human civilization has risen to a central position, so much so that even partial progress will induce the progress of civilization.

And more than 1 century after the first appearance of the second-generation spacecraft, through Cao Chuan, through the research department, they integrated a deuterium-tritium fusion energy reactor, a Higgs particle generator, a quantum computer, and quantum entanglement communication equipment on the spacecraft. Deep space radars, atomic-level materials, protective force fields, energy absorption equipment... So much technology, and it has not yet involved weapons and equipment, makes people have to admit it. The spaceship is the crown jewel of the big industrial system.

"So... Are there still two last technologies left? In this way, the full version of the third-generation ship can be implemented and put into production? After a long period of regular simulation, Cao Chuan gained insight into the general appearance of the third-generation spaceship.

"The first is the issue of acceleration, and the second is the hydrogen-helium fusion energy reactor. Sure enough, it's a big problem that has plagued mankind for many years! "He led the development of the original spacecraft from the rocket, to the first generation of moon-class spacecraft, and the vast majority of the second-generation Yang-class spacecraft, there is nothing he doesn't know.

"Master, do these two problems have to be solved in the third-generation spaceship stage?" Nana asked, "Maybe it's time to stay until the fourth generation?" ”

"No," Cao Chuan shook his head. Let's talk about the first problem, the gap between the current speed of the spacecraft and the acceleration of the spacecraft is too far, from the star spacecraft, the conventional speed is 1/2 of the speed of light, but what about the acceleration, in order to avoid accidents for ordinary human passengers, the maximum usually does not exceed 10G, imagine. It takes 17 days to accelerate from a standstill to half the speed of light. And when mooring, it also takes 17 days to slow down. ”

"If you talk about the civilian field, it may be acceptable, but during the war, a spacecraft that takes 17 days to stop completely will become extremely clumsy and unexpected. There's no way to do anything, can you imagine what it's like? ”

These are the biggest drawbacks of the slow acceleration increase, so on the third generation of ships, he had to solve this problem - let humans withstand more acceleration.

The method has strengthened the body. Genetically modified immigrant offspring can typically withstand an acceleration of 20G; and the buffer structure, by wrapping and binding human beings, it is like putting a pillow on yourself, and it can also withstand a little more acceleration, but these do not fundamentally solve the problem, there must be a complete solution.

If the acceleration problem has to be solved, the hydrogen-helium fusion energy reactor does not seem to be needed on the surface, but in fact, it is also indispensable, which will greatly improve the efficiency and environmental adaptability of the spacecraft's energy supply, otherwise the third-generation spacecraft that is too picky will run out of energy and have to stay on nearby gaseous planets and stars for at least half a year before it can be replenished.

Hydrogen helium fusion energy means that human fusion energy technology has entered the highest peak of fusion energy technology from the initial contact, cognition, and mastery, and human beings have finally mastered the secret of star combustion, and have come into contact with the great knowledge of the universe, and then it is a bottleneck.

No one knows what it is, whether it is a more special form of fusion energy or a new energy source, in short, now, he must solve it completely.

Cao Chuan pondered that from the point of view of the two, the two major problems would take several years of rule simulation to solve, but no matter how you look at it, hydrogen and helium fusion can be easily solved.

Starting from a simple point is a characteristic of a normal person, and starting with a difficult one is a characteristic of a certain creature with an M personality, and Cao Chuan is a normal person, so there is no need to take an unusual path.

"Can hydrogen helium fusion?" Cao Chuan believes that the reason for its simplicity is undoubtedly the atomic-level materials and dark matter materials at hand, both of which are very heat-resistant, and even completely ignore heat energy, so he has more confidence to solve the problem.

Here's a long simulation of the rules, a year, two years... Not long after, in 2179, outside a base on Planet 3, a prototype of an envisioned hydrogen-helium fusion energy reactor had just been built.

From the bottom of the sunken structure, submerged in the huge underground space, surrounded by a circle of atomic-level material outer wall layer that is enough to accommodate a high temperature of nearly 10,000 degrees Celsius, inside is a dark matter compartment, the role of dark matter is used to guide the instantaneous heat energy flow direction, not to let the reactor be evenly heated and melted, but to let the heat energy export to a fixed outlet, and then inside is the electromagnetic confinement layer, like a plasma cloud that wraps the star, this structure is artificially created.

The electromagnetic confinement layer is quite complex, first of all, it is a primitive energy machine, which can constrain the range of fusion energy, to further isolate the space, and ensure that the fusion energy will not spill over, because in the electromagnetic confinement layer, the most common fusion energy reaction in the universe up to 1 billion degrees Celsius occurs.

Secondly, there are pipe structures in the electromagnetic confinement layer, and there are also dark matter conduits in these pipe structures, which means that the heat energy generated through fusion energy must pass through the conduit before it can leave, otherwise the heat energy will not react with the dark matter that is completely conductive.

Then the surging energy generated by the fusion energy will be transmitted along the layers of such a structure, so that the energy will be gradually and steadily released, avoiding the evolution of an explosion, and will be used to propel the spacecraft, maintain the life support system, run the Higgs particle generator, protective force field, weapon launch and many other places.

This is the basic structure of the hydrogen helium fusion energy reactor, and there are still more problems in the realization process, it is definitely not easy to build, the construction is completed in front of it, with a bloated body of nearly 500 meters * 500 meters * 500 meters, and there is still a lot of distance from the goal.
