Just when Chu Yuesheng and Gong Zimeng were in a daze looking at the robot that had begun the countdown to self-detonation, the third power station in Central City, which was a few kilometers away from them, had already sounded a piercing alarm that was enough to wake up the entire factory area.

Of course, at this time, there were no workers in the power plant, only the robots responsible for daily inspections walked back and forth in the factory area according to the procedures, tinkering with the defects they noticed. In the entire power plant, except for the main control room, there are no living people moving around the plant area at all.

And the source of the alarm is the only main control room where there is still human activity.

Unlike the quiet factory area outside that had just been pierced by the sound of an alarm, the main control room at this moment has become a mess.

Although in the past few hundred years, human science and technology have made great progress. But as the saying goes, the essence of human science is to boil water in a variety of ways. As long as we have not gotten rid of electricity and obtained more advanced energy sources, the core of human society will not change much.

Even if nuclear energy is mastered, all human beings can do is to boil water more efficiently and cleanly, so that the water becomes water vapor that expands thousands of times in volume, so as to drive the steam turbine to rotate and drive the electric motor to generate electricity.

The main core of the power station, which supplies about one-sixth of the central city, is an "artificial sun" built to imitate the principle of solar combustion, which is also known as a "nuclear fusion" reactor.

Yes, hundreds of years have passed, and human beings are still using nuclear energy, and those higher energies are either still in the laboratory, or still on paper, and they can't even touch the real thing. In terms of practicality and economy, nuclear fusion, which is easy to build and clean and efficient, is the most suitable energy for human use today.

Originally, when human beings used nuclear fission as the main way to obtain nuclear energy, they also needed to worry about the nuclear radiation caused by radioactive products, so human beings developed a transmutation system (ADS transmutation system) for this purpose, which forcibly emptied the radioactivity of intermediate products and turned them into extremely low radioactive waste residues, which have been negligible to the environment. But after all, it is a symptomatic treatment, and if we really want to treat the root cause, we still need to deal with the problem of nuclear waste generation from the source.

It is in this context that nuclear fusion technology, which uses radioactive light elements such as deuterium, tritium, helium-3, and lithium-6 as fuel, has finally been conquered by mankind. Humanity has succeeded in seizing the light of the stars, igniting one dazzling and scorching artificial sun after another in its own world.

The footsteps of mankind have also begun to move towards space in real time because of the maturity of nuclear fusion technology. After all, unlike nuclear fission, which requires a lot of space to store and has low energy efficiency, nuclear fusion requires light fuel, and the radioactivity of light elements is much less than that of traditional fission raw materials such as uranium, plutonium, and thorium. Often only a small tank of fusion material is needed to maintain the normal operation of an artificial sun for a long time, and with the matching steam turbine, it can output a stable power supply for the equipment of the surrounding human civilization.

Of course, because the initial nuclear fusion often used light particles, although these raw materials are widely found in seawater and lunar soil, but with the complete withdrawal of human beings from the third orbit of the solar system, after losing the main source of these elements, human beings are gradually facing the crisis of artificial solar fuel shortage. Mankind had to look for new fusion materials, and heavy nuclear fusion reactors came into being.

The transition from light to heavy fusion, although it is only a word difference, represents a technological leap. The prospect of human beings using fusion technology has been completely opened.

Heavy nuclear fusion reactors use a much wider range of elements, and it can be said that as long as the elements in the periodic table are ranked before iron 56, they are all "fuels" that can be burned. Although the "calorific value" of those stones is very low, and the energy produced per unit mass of burning is completely incomparable to that of light nuclides, it can't stand the large amount of stuff and the tube is full, as long as it is not a gas giant, stones and sand can be found on any planet. You only need to burn stones to generate electricity, is there anything more fantastic than this?

It can be said that in the technology of boiling water, human beings have gradually come to an end. The heavy nuclear fusion reactor is the ultimate product of boiling water. But the problem is that further down, where is the future of mankind and where should mankind develop in the future, human beings are still at a loss for the time being.

After many, many years of development, mankind has developed quite mature attainments in the construction and use of heavy nuclear fission reactors. In general, the human use of heavy nuclear fission reactors should not be accidental.

But in such cases, accidents often happen in ways that humans cannot and absolutely do not want to see. Just like now, at that time, the third power station in Canterlot......

"Are all the control sticks plugged in?"

"Yes, but the core temperature is above the threshold and the control rods are melting!"

"The change of the magnetic field is instantly disordered, and the temperature of the magnetic confinement ring increases by 200%!"

One bad news after another was like a hammer smashed into the chief engineer's heart, he glanced at the young operator who was kicked by himself and was now huddled in a ball hiding in the corner, forced down the urge to kill in his heart, and gave his own order in a tone that was about to vomit blood: "No way, the coolant valve is fully open, cut the fifth steam turbine." ”

Damn, if this bastard hadn't suddenly yawned while performing a critical operation, and didn't notice that the command had entered an extra single digit, the control rod he was responsible for wouldn't have all popped out! The reactor that had lost the suppression of the control rod was like a hole in the inner wall of the whole whole, and the local abrupt thermal power seriously damaged the overall environment of the magnetic field constraints, causing a huge shock to all the control rods, making them more or less malfunction. And these small flaws are superimposed, and in this case, it will kill people!

Artificial sun, even if it is artificial, it is also the sun. The surface temperature is 6,000 degrees, the core temperature is 15 million degrees, if you don't use a control rod with a super magnetic field to confine the plasma in a very small space, the uncontrolled artificial sun will quickly expand into a real small sun, and the unrestrained energy explosion is enough to blow up everything within a radius of dozens of miles!

Canterlot, the symbol of humanity, cannot be exposed to such dangers.
