I accidentally got a two-way foil in my second level civilization

The concept of the magnetohydrodynamic generator actually emerged a long time ago.

Based on the Hall effect, it is a device that generates electricity by the relative motion between a conductive fluid, such as air or liquid, and a magnetic field.

Since it omits the step of mechanical energy conversion, its power - generation efficiency has been significantly improved.

In fact, in his previous life, he had envisioned using this technology for power generation.

However, due to the extremely tight schedule, there was no extra time for in - depth research. Helplessly, he had to choose the relatively simple steam - generation power - generation method.

But this time... he had absolutely abundant time!

A flash of excitement appeared in Lü Yongchang's eyes. He reached out and grabbed a piece of white paper, flattening it on his office desk.

"Brother Xu, come and take a look at this plan!"

As he spoke, Lü Yongchang picked up the pen beside him, uncapped it, and started drawing directly on the white paper!

Seeing Lü Yongchang's actions, a hint of confusion appeared in Fang Xu's eyes.

This... For a simple steam - generation power - generation method, did it really need a special plan?

There were so many controlled nuclear fission power plants in Xia Country. Couldn't they just copy one of the plans?

Thinking this way, Fang Xu took a step forward and carefully looked at the white A4 paper in front of Lü Yongchang.

Looking at the straight and neat lines on the paper, a hint of amazement appeared in Fang Xu's eyes.

"Your hand - drawing skills... are amazing!"

Lü Yongchang's hand suddenly paused, and then he explained with a smile, "Oh! I learned it on my own. Otherwise, how could I draw those simple diagrams on the blackboard?"

Fang Xu nodded in admiration.

This wasn't something that could be learned easily!

At least, he couldn't do it.

Not to mention him, even among the academicians of the Academy of Sciences, probably not many people's drawing skills could reach this level!

The office gradually fell silent.

Apart from the breathing of the two people, the only sound was the "rustling" of the pen in Lü Yongchang's hand as it划过 the white paper.

"What is this..."

Fang Xu's eyebrows shot up.

As the lines on the drawing gradually became complete, he could tell what Lü Yongchang was drawing!

"Magnetohydrodynamic generator?"

Lü Yongchang didn't stop his hand. He chuckled and nodded. "That's right! It's a magnetohydrodynamic generator!"

"In my opinion, this is simply the most suitable device for controlled nuclear fusion, without a doubt!"

Fang Xu's brows instantly furrowed.

After pondering for a moment, he said in a somewhat serious tone, "Yongchang, I know that the power - generation efficiency of the magnetohydrodynamic generator is very high.

"But... the magnetohydrodynamic generator has several fatal flaws, and this technology is not yet mature!

"Is it a bit... too hasty to use it in controlled nuclear fusion?"

The pen in Lü Yongchang's hand suddenly stopped.

He slowly looked up at Fang Xu, shook his head with a smile. "Difficulties?"

"Currently, there are only two main difficulties restricting the magnetohydrodynamic power - generation technology.

"First, the magnetohydrodynamic power - generation technology requires inert gases containing trace amounts of alkali metals such as potassium and cesium as the working fluid.

"Second, it's the high - temperature environment for the normal operation of the magnetohydrodynamic generator.

"Am I right?"

Fang Xu's eyes focused slightly, and he nodded gently. "As for the first one, it's still a bit difficult to solve at present.

"Large - scale production of inert gases, we don't have this technology yet.

"According to the current technological means, if we use a magnetohydrodynamic generator, even if the working fluid can be recycled, this cost will far exceed our expectations!"

Lü Yongchang stared at Fang Xu meaningfully, a faint smile appearing in his eyes.

"Brother Xu, are you sure we don't have the technology to produce inert gases yet?"

Fang Xu's brows furrowed slightly. After carefully recalling in his mind, he slowly shook his head. "I'm sure. At least as of last week, I haven't seen any related technology in Xia Country, or even in international academic journals!"

Lü Yongchang didn't say anything. He just gave Fang Xu a deep look, then picked up the pen again and started writing and drawing on the paper.

Seeing this scene, Fang Xu's brows furrowed even deeper, and an inexplicable sense of restlessness welled up in his heart.

Vaguely, he had a premonition.

He seemed to have overlooked something extremely important!

But no matter how hard he thought, Fang Xu couldn't figure out what it was.

"Yongchang?"

A hint of eagerness appeared in Fang Xu's eyes, and he asked Lü Yongchang in a low voice, "What exactly is the technology? Hurry up and tell me!"

Lü Yongchang still didn't speak. He just gently tapped the office desk with the pen tip.

Attracted by Lü Yongchang's actions, Fang Xu lowered his head and looked at the white paper in front of him.

A line of elegant pen writing appeared on the white paper.

1 2 H+ 1 3 H→ 2 4 He+ 0 1 n+17.6MeV

This was... the reaction formula of deuterium - tritium fusion!

Looking at this extremely familiar reaction formula, Fang Xu was immediately stunned on the spot.

His lips trembled slightly, and a smile gradually appeared on both sides of his cheeks.

"So that's it! So that's it!"

No wonder he always felt that he had overlooked something important!

He had considered all the external factors, but he had overlooked the most important internal factor!

Different from ordinary thermal power generation and nuclear fission power plants, deuterium - tritium fusion itself produces helium!

Hydrogen - 2 and hydrogen - 3 undergo a fusion reaction under high - temperature conditions to produce helium - 4 and neutrons. This was simply high - school physics knowledge, but... he, an academician, had actually overlooked it!

Fang Xu shook his head with a bitter smile. "In that case, the first difficulty has been solved."

The smile in Lü Yongchang's eyes became more obvious. "For us now, is the second difficulty still a difficulty?"

Fang Xu was stunned for a moment, then suddenly slapped his own head!

"Ah! What's wrong with my brain recently?!"

The new material in the stellarator reactor could resist the high temperature of controlled nuclear fusion. Could it not resist the "low temperature" of 2000 - 3000K when the magnetohydrodynamic generator was working?

The more Fang Xu thought about it, the more excited he became. He put his hands behind his back and kept pacing around Lü Yongchang's office.

"Yes! Yes! Yes!"

"Helium can be produced in the deuterium - tritium fusion reactor! And it's high - temperature gas at hundreds of millions of degrees Celsius!"

"We don't even need to consume energy to heat it!"

"This is simply, simply a perfect power - generation plan!"

Lü Yongchang chuckled and handed the sketch on the table to Fang Xu. "Brother Xu, check if there are any talents in this area at Sandaokou University. If there are... make a prototype as soon as possible!"

"Let's strive to complete the first controlled nuclear fusion demonstration reactor within half a year!"

Fang Xu was excited. He reached out and took the sketch handed by Lü Yongchang, nodding vigorously!

"Okay!"

"Don't worry. I'll take care of this!"

"I guarantee that you'll see the prototype of the magnetohydrodynamic generator within two months!"
