Chapter 706: Song Yao: I've been rolled again

What is this concept? You'll know if you compare it.

On the tokamak device, the Xia Nation's latest EAST achieved 1066 seconds, which is the current world record.

In the same category, South Korea's KSTAR achieved maintaining 48 seconds at 100 million degrees Celsius for the first time this April, and plans to challenge 300 seconds a year later.

In Europe, even for JET, long-term operating temperatures are generally lower than EAST, and most other devices find it difficult to break through 100 seconds.

Therefore, Xu Qingzhou and the others set the goal at thousand-second-level operation; once successful, they can basically surpass 90% of similar projects in the world.

Stellarators have already achieved 30 minutes of stable operation, but tokamaks are still struggling at the second level; does it seem very weak?

Of course not.

This belongs to two different technical routes.

Simply put, the tokamak is a "sprint champion," suitable for quickly verifying high-temperature fusion physics; the technology is mature but difficult to generate electricity continuously.

The stellarator is a "marathon runner," capable of solving the core bottleneck of commercialization—steady-state operation—but it needs to break through the precision manufacturing problem of three-dimensional magnetic fields, and the cost remains high.

Both sides have significant pain points.

It can be said that at the moment, the final path for the commercialization of controllable nuclear fusion has not yet been finalized.

This is also the reason why Germany, even if it exchanges its stellarator technology, wants to get their superconducting thin film.

At the critical moment of the technology war, the stellarator needs a new breakthrough, and high-performance superconducting thin film is the opportunity for a breakthrough.

Similarly, their progress being so smooth also benefits from exchanging for quite a few advanced technologies through the authorization of superconducting thin film.

For example, the plasma heating technology of the Xia Nation's EAST, and the divertor material technology of Europe's JET (Joint European Torus).

Able to learn from each other's strengths and gather the strengths of many.

6:30 PM.

"I'm back."

Song Yao carried a pile of things into the house, put them on the table, and let out a long breath. She has now summarized a rule: after having a husband, she has really become a weak woman.

If it were back in high school, she could carry this much stuff and walk two streets without even panting.

Having a man really makes one prone to degeneration.

After all, all the heavy lifting is done by Xu Qingzhou.

"Eh, where is he?"

There was no one in the living room, only Er Miao lying on the sofa, dozing off.

Song Yao took out the fruit she bought, washed it, and carried it upstairs.

In the study, Xu Qingzhou's brows were tightly furrowed, the tip of his pen tapping lightly. She walked over in her slippers.

Xu Qingzhou noticed the girl coming in and asked with a smile: "Back so early? Didn't you say you were going to see a movie?"

"No good movies."

Song Yao put the fruit platter on the table, hugged Xu Qingzhou from behind, and fed a piece of apple into Xu Qingzhou's mouth. "Had dinner yet?"

Xu Qingzhou stopped writing, enjoying the girl's feeding, and nodded, saying: "Had noodles."

"Didn't you say you were resting today and not looking at data?"

Song Yao looked at the manuscript on the table and muttered. The manuscript was filled with dense calculations, seemingly topological optimization design. "Still the problem of multi-physics coupling instability?"

"Right, by calculating the magnetic skeleton morphology through mechanics, I plan to try a bionic honeycomb structure to disperse the Lorentz force load and reduce stress concentration."

Xu Qingzhou nodded, flipping through the manuscript to explain to Song Yao, "Targeting fluid and thermal shock, I want to make a nano-buffer cavity inside..."

"Amazing."

Song Yao often looked at the research institute's experimental plans and Xu Qingzhou's calculation manuscripts, so she knew quite a bit about the content inside and could understand it.

"Rolled?"

Xu Qingzhou turned his head and kissed the girl on the face.

"You are working hard, while I am playing; there is a sense of degeneration." Song Yao twirled Xu Qingzhou's hair.

"Then do you want to try seducing me to degenerate with you?"

Xu Qingzhou gave Song Yao an idea, and by the way, pulled the girl to sit on his lap. Smelling this faint fragrance always made people restless.

"How to seduce?"

Song Yao put her chin on Xu Qingzhou's shoulder, her eyes looking out the window; this posture was very comfortable for hugging.

"For example, that evening dress last time... hiss~ stop stop stop, if you don't let go, I'm going to bite back!"

Before Xu Qingzhou finished speaking, his neck had already been bitten by Song Yao.

Song Yao said *wu-wu*. ===== CHAPTER 707 =====
