Tokamak.

A ring-shaped device that creates an environment and ultra-high temperature for deuterium and tritium fusion by confinement electromagnetic wave drive to achieve human control of nuclear fusion reactions.

At present, controlled thermonuclear fusion has been achieved on conventional tokamak devices, and Huaguo's artificial sun uses the principle of tokamak devices, which has recently achieved a temperature of hundreds of millions of times and exceeded 1,000 seconds.

However, the operating time of the tokamak device is too short, and it needs to consume a lot of electricity to maintain a strong magnetic field and an extreme superconducting environment.

Physicists measure the efficiency of a tokamak device by using the ratio of energy produced to energy consumed, the Q value.

A Q value greater than 1 means that the fusion device has energy output, rather than a successful theory that can only be tested in the laboratory.

At the same time, in terms of the current efficiency of human energy utilization, coupled with the expectation that human beings will replace thermal power generation with this technology, it is possible to become a mainstream energy supply only when the Q value reaches more than 30 points.

If you want to reach the scale of science fiction works that can power large spaceships and space cities, then the Q value must at least break thousands to have hope.

However, none of the tokamaks that have been built so far on the Blue Star can run for a long time and achieve a Q value of more than 1, and Huaguo's artificial sun is only a possibility of a breakthrough.

Lu Yu looked at the tokamak device made by the alien civilization in front of him for a while, and then hurriedly asked, "Since it may be a nuclear fusion reaction device, why did you put this device here?" ”

This question is clearly not the professor's strong point, he is only an expert in nuclear physics, and at a glance he recognizes the device, and he can't wait to rush in.

Proven controlled nuclear fusion technology can fundamentally change the way humans live.

Technologies that used to be hidden due to high energy consumption in production will become unimaginable due to the decline in energy costs.

It can be said that the mature controllable nuclear fusion technology is very likely to be a barrier to the big screen, and after the breakthrough, it is very likely that mankind will usher in the fourth big bang of science and technology!

However, it has been 50 years since the theory of controlled nuclear fusion was proposed, and it is only in these years that some progress has been made.

It's no wonder that the professor rushed over excitedly after recognizing the device.

You know, this civilization is 500 years ahead of human technology, and if you can analyze the tokamak device they made, it has an unimaginable role in promoting human technology!

The Silver Star circled around the tokamak device like a display case, and Professor Mao, who was squeezed out of the video, finally came back in a hurry, and finally sent away the nuclear physicist who was still obsessively staring at the device.

"First of all, we came up with the conjecture that the device in front of us is most likely an antique."

Professor Mao said straight to the point: "Let's put aside the most eye-catching nuclear fusion device, and think about why this civilization has put this device at the entrance of the building. ”

"We assume that this complex, which maintains the light source and is significantly behind the rest of the city, is likely to be a museum of the history of science and technology of this dying civilization."

"The fact that this device can be placed at the entrance means that it has been of great significance to the course of civilization as a whole."

"It's like a steam engine or a Jenny loom in an industrial museum."

"In the eyes of this civilization, this nuclear fusion reactor, which is very likely to be the first generation of full-fledged nuclear fusion reactors, is no different from the steam engine or textile machine of the first industrial revolution that we look at from a modern perspective!"

"It's easy to prove it, let's go to the next place and see if there are any objects like this device on display."

Lu Yu endured his excitement, left the tokamak device and walked nearly a hundred meters into the building complex, and sure enough, he saw a metal platform again.

What is shown above is no longer a mechanic, but a structural diagram of some kind of substance.

Lu Yu, who verified his guess, did not continue to advance into the depths, but returned to the nuclear fusion device at the entrance.

Ten birds in the forest are not as good as one bird in hand, and without being sure how long they can stay here, grasping the tokamak device at the entrance is already worthy of this opportunity to jump in space.

Lu Yu, who returned to the entrance, looked at the device as high as three or four floors and felt a little embarrassed, although there was a real thing in front of him, if he wanted to reverse crack it, he needed to disassemble it and get a glimpse of the structure inside.

Not to mention how much such a project does for Lu Yu, who is alone, the premise for achieving it is that he must leave the safe cockpit and go to the outside world where danger will suddenly come.

But Lu Yu was tempted!

Even the tens of thousands of tons of gold that he had before didn't make him feel the slightest excitement to leave the cockpit, but the fusion reactor in front of him gave him the urge to leave the cockpit.

Nuclear fusion.

If the device in front of me is really a full-fledged nuclear fusion device, it may be the greatest achievement since I stepped into the sea of stars.

This is not only for me, but also for this civilization of mankind.

Lu Yu didn't even discuss it with the expert group, just informed them of his decision, put on a spacesuit, and decisively walked out of the cockpit.

Looking at the huge device in front of him, which was huge for the size of a human being, Lu Yu, who had cut off the connection with the blue star, exhaled lightly and came to the huge metal platform.

The half-human-high trapezoidal metal platform was covered with a thick layer of dust, and Lu Yu, who was for safety, tried to wipe off the dust.

Then he was amazed by the fact that the metal plates under the dust were engraved with patterns and alien words.

I cleaned all the metal plates next to it to dust, and sure enough, each silver-white metal plate the size of A4 paper was engraved with different patterns and words.

"Drawings!!"

"Is it really the blueprint of a nuclear fusion reactor??"

The thought that would make people faint with such a surprise flashed through their minds, and this is not only the nuclear fusion reactor in front of you, but the entire alien museum has hundreds of such metal abutments!!

Carving words into stone is the longest way that humans can think of to preserve words, and this civilization has carved everything that has led to its glory on metal plates.

Although Lu Yu didn't know how many years this civilization had perished, the legacy they left behind would be inherited by the humans of Blue Star!

Lu Yu looked at the thousands of display cases in the museum and thought silently.

There is a limit to observers, so I won't be an observer!

From today onwards, I, Lu Yu, will become the strongest porter of mankind and transport everything in this alien civilization museum back to Blue Star!
