Controlled nuclear fusion is very important to the super-rich on the entire blue planet. Grasping the trend can indeed make their net worth skyrocket.

However, in the face of biomedical technology that can extend life by thirty to fifty years, the technology of controlled nuclear fusion is really worthless.

Saraf is quite familiar with the group of super-rich people. As long as it can keep them alive, even if they spend tens of billions or hundreds of billions, it is just a number in their eyes.

Ordinary people may have to wait for decades to get an organ transplant, but this group of super-rich people are so powerful that they can find a suitable organ in less than a day.

Li Yunfei's mouth twitched, and he said unhappily: "If adding money is useful and can prolong life, then Qin Shihuang would have unified the world long ago."

"Just wait and see. This technique seems to be just around the corner, but who knows when it will really break through?"

Lu Guofeng doesn't understand biomedical technology, but he knows a lot about controlled nuclear fusion.

This feeling of seeming to be just one step away from success is often really just that one step away.

Wireless energy, clean energy, and safe energy from controlled nuclear fusion were scientifically proven to be feasible decades ago, but in terms of engineering materials, there is still a gap of fifty years.

Scientists in the field have been researching for decades, but there has not been any technological breakthrough in engineering materials. This technology has been called the "permanent fifty years."

Who would have thought.

It is in recent years that the technology of controlled nuclear fusion has made key breakthroughs.

"Chief Engineer Lu, why have you always been working on controlled nuclear fusion and not controlled nuclear fission?" Li Yunfei asked curiously as he visited the equipment.

"Nuclear fission is an atomic bomb, and nuclear fusion is a hydrogen bomb. The equivalent of fusion is dozens or even hundreds of times greater than that of fission."

"In terms of cost-effectiveness, controlled nuclear fusion is naturally much better than controlled nuclear fission, and the feasibility of the solution is also higher."

"But this energy is released instantly. The conditions for fusion are much more difficult than fission. It requires a temperature of at least hundreds of millions, and the higher the better."

"This leads to a problem. It is really difficult to control this energy and make it output continuously and stably like a power station."

"There is absolutely no material on the blue planet that can withstand high temperatures of over 100 million degrees, so we built a tokamak device. Yes, that's the tokamak device." Lu Guofeng pointed to a ring-shaped device in the room.

The tokamak device can be roughly divided into four parts.

The annular shell, vacuum chamber, magnets and coils form a high-temperature superconducting environment.

He took out a cross-section diagram of the device and showed it to the two of them: "Nuclear fusion has much greater energy than nuclear fission, and it is also much safer."

"Nuclear fission will produce highly radioactive nuclear waste, but controlled nuclear fusion will not. He has a basic formula here."

Lu Guofeng became excited while speaking. He picked up the marker next to him and started practicing the formula.

The reaction time of nuclear fusion multiplied by the square of the temperature, and then multiplied by the fourth power of the magnetic field strength B, can give the final power of controlled nuclear fusion.

Theoretically, if the magnetic field is doubled, the efficiency of controlled nuclear fusion can be increased 16 times.

Li Yunfei yawned subconsciously as he listened to the astronomical formula of nuclear fusion equation.

This kind of incomprehensible thing is really perfect for learning and hypnosis.

Saraf was standing next to them, and his performance was even worse.

He barely understood Chinese, so this kind of professional knowledge sounded even more confusing to him.

However, after listening to Lu Guofeng's clear and logical explanation, he nodded in agreement, and from time to time he would give a thumbs up and say with emotion, "That's right, yes! yes!"

"Boy, do you really understand?" "Brother, you know me. If you don't understand, how can I understand?"

"Then what do you say yes to?"

"Although I don't understand, at least I should have a correct attitude towards learning!" Saraf said confidently.

After he finished speaking, he yawned again, then lowered his voice and asked in a low voice: "Boss, can you record this? I want to watch it when I can't sleep at night. This hypnotic effect must be good!"

"Don't you have to have a good attitude towards study?"

"Learning attitude is learning attitude, not understanding is not understanding, the two should never be confused!"

Lu Guofeng listened to the conversation between the two and had no intention to continue introducing his tokamak device.

He looked at Li Yunfei and said, "You can't prop up a rotten wood, and you can't carve a rotten wood!"

"Brother, what do these two sentences mean?"

"The meaning is very simple, that is, we are not talented in this area."

"It's okay, it doesn't matter. It's normal for an investor not to understand. Just be clear when giving the money."

"Chief Designer Lu, when our Sarab researchers come over, please explain it clearly to them. If they don't understand, it will be a big problem!" Saraf said sincerely.

After hearing this, Lu Guofeng was filled with emotion. This is simply the dream investor of scientific researchers!

He gives money readily and asks few questions. He is not like some people who pretend to know everything.

On the market today.

The mainstream still uses the magnetic field of copper conductors, and the subsequent technological development path has led to three polarizations.

One is low-temperature superconductivity, one is room-temperature superconductivity, and the other is high-temperature superconductivity.

"Mr. Li, Your Highness the Crown Prince, low-temperature superconductors actually appeared earlier than you think, more than a hundred years ago."

"Its biggest problem is that the upper critical magnetic field is relatively low, at about 11 to 12 Tesla, it will suddenly lose its superconducting properties."

"Because the upper limit is very low, its magnetic field can only be made that big at most. Do you two understand?"

Li Yunfei and Saraf looked at each other, and both of them had an awkward yet polite smile on their faces.

"Chief Engineer Lu, what about high-temperature superconductors?"

Lu Guofeng said proudly: "The theoretical magnetic field of high-temperature superconductors can reach nearly 40 Teslas at most. Currently, we can reach nearly Teslas."

"This value is about three times the magnetic field strength of low-temperature superconductors and fifty times the energy output."

"It has higher energy output, higher restraint strength, and guaranteed stability, so it has the economic effect of mass production."

Li Yunfei immediately grasped the key point and asked, "So now, can we try to build a commercial controlled nuclear fusion facility?"

"Yes, that's right. As long as the funds are in place, we can indeed move out of the laboratory and try commercial construction. High-temperature superconductivity is the last bridge to commercial controlled nuclear fusion."

"To be honest, we have already made a breakthrough in the most critical technology some time ago, and that is the superconducting cable twisting technology," said Lu Guofeng.

"How come I don't know this?" (End of this chapter)
