Two Hundred and Ninetieth IX 1 See Old Friends (2)

Ye Han was at a loss for words. When it comes to tactical issues, he is indeed an expert among experts, but when it comes to technical issues, Qu Jiang is the real master.

Qu Jiang suddenly changed the subject: "However, the internal combustion engine power pack is too noisy and not suitable for power armor."

"Isn't the current internal combustion engine quite quiet?" Ye Han asked strangely.

"The internal combustion engine is quiet, but what about the generator? The hydraulic armor is driven by electricity, and the mechanical energy must be converted into electrical energy to drive the hydraulic equipment of the whole body." Qu Jiang explained.

"Understood." Ye Han nodded, "What, can I ask you a question?"

"You have asked so many questions, is this one more?" Qu Jiang said angrily.

Ye Han chuckled: "If there is something wrong, don't laugh at me."

"Say it, I promise, I won't laugh at you as much as possible." Qu Jiang promised insincerely.

Ye Han coughed lightly and cleared his throat: "I remember reading it when I was a child. The Voyagers of the Americans and the satellites of the former Soviet Union used nuclear batteries. Can this not be used on power armor? You Don't tell me it's been so many years, we can't even make a nuclear battery."

Qu Jiang was so angry that he rolled his eyes: "You know what, plutonium batteries are used on satellites, which are two different things from nuclear power plants!"

"I just want to ask if I don't understand." Ye Han listened attentively.

Qu Jiang sighed, and explained: "Have you heard of the element plutonium?"

"You know, nuclear materials are used to make atomic bombs. The critical mass seems to be a little over five kilograms." Ye Han said.

Qu Jiang smiled: "You know a lot, but do you know what isotopes are?"

"It's still a question!" Ye Han curled his lips unabashedly.

"Well, tell me how many isotopes there are in plutonium!"

"I don't know!" Ye Han said bluntly.

"No knowledge, no skills!" Qu Jiang curled his lips in a learned manner, and then sighed, "How can I tell you?"

"It doesn't matter what you think of and what you say, I am very receptive." Ye Han said.

Qu Jiang thought for a while and said: "Plutonium has six isotopes, and the most important plutonium-239 can be used to make nuclear weapons; plutonium-238 is also relatively common. The half-life of this thing is only 88 years. When this thing decays, it can continuously release high The temperature looks like... well, like dark red charcoal, the thermal battery on the satellite actually absorbs the heat of plutonium to generate electricity, it is said to be a nuclear battery, but it is actually not the same thing as the fusion reaction in a nuclear power plant."

"Understood!" Ye Han nodded heavily, "I still think that nuclear batteries and nuclear power plants are the same thing, and I have never understood why I can make nuclear reactors as big as batteries, so why build such a big nuclear power plant."

"Don't tell me, we really have micro-reactor technology, and the reactor we built is only as big as a pressure cooker. The problem is that the fuel of this thing is exactly the same as that of a nuclear power plant. Carrying a nuclear reactor on the battlefield, hehe, what if the reactor is pierced by bullets? What consequences?"

Ye Han's cheeks twitched, and the hot word "nuclear leak" suddenly appeared in his heart.

"The ones that are easy to use are either too dangerous, inappropriate, or the technology is immature. Let's honestly stick to the battery road until the end." Qu Jiang said helplessly.

"What about the fuel cell?" Ye Han asked again.

"I still don't understand!" Qu Jiang wanted to slap Ye Han twice, "Fuel cells have the word fuel, how can they generate electricity without fuel? Besides, they use hydrogen or methane, both of which are combustible gases. I dare to use these things As a driving force, do you dare to take it to the battlefield?"

"Don't dare." Ye Han replied honestly, shut his mouth and didn't ask another word.

"Is there anything else you want to ask?" Qu Jiang asked.

"No more." Ye Han shook his head.

People who do research rely on their brains for food, and they have to think about it for a long time. I don’t know how many times I have thought about it. He, a big soldier who relies on physical fitness for food, can’t catch up with him. It’s better not to make jokes about these low-level questions. If there is anything I don’t understand, it’s not too late to ask after I get the power armor.

"Then go back and wait.

"Qu Jiang issued the order to expel the guests directly.

"It's okay, I can wait." Ye Han said.

"I have no place for you to wait here." Qu Jiang said very bluntly, "It takes several hours to print the inner lining alone. You don't mind it. We still want to rest."

3D printing is not that simple. Although the structure of the armor lining is simple, it still takes several hours to complete a part. If it is not equipped with multiple 3D printers in the experimental cabin, the printing of the lining alone will take several days.

Ye Han really wanted to fight for it again, but hesitated again and again, and finally left the experimental cabin obediently.

Before leaving, Qu Jiang handed Ye Han a hard card the size of a bank card: "This is your ID, go back and wait for my notice."

Ye Han took the card and pinned it to his chest, and reluctantly left the experimental cabin.

There was no one outside the experimental cabin, and the lieutenant who sent him here had already left. Opposite the experimental cabin, a truck was unloading giant ants. Ye Han stared blankly for a while, and said hello to the power armor responsible for unloading the truck.

Returning to the dormitory along the way when he came, Ye Han fell on the bed full of worries, silently pondering the previous experience.

The owner of the power armor on the opposite side must also be an elite carefully selected by the military. I don't know how many soldiers with power armor are on board.

According to Ye Han's understanding, the most expensive military branch is the pilot, and the training cost of each pilot is astronomical. If the money is converted into gold, its weight will be higher than the weight of the pilot!

However, even though the training cost of pilots is so high, I have never heard of any ace having tailor-made fighters. Since the power armor is all tailor-made, the treatment of users should at least be equal to that of pilots.

In other words, only officers are eligible to use power armor, at least until power armor becomes popular on a large scale, it is impossible for ordinary soldiers to have power armor.

But how should the few fighters who came with him be arranged? The captain said that he would check the situation of several people before making a decision. Could this statement be just perfunctory, but in fact he had already made up his mind to send all four of them away?

If I had known this, I would have left them in Fuyun.

While thinking wildly, Ye Han suddenly heard footsteps. He didn't care at first, but the footsteps stopped outside the door.

Ye Han sat up suspiciously, and when his eyes fell on the hatch, the hatch had already opened from the outside, and a tall figure stepped into the dormitory.

This man has a dark face with unusually tough facial lines, full of the masculinity of a soldier. He is at least 1.8 meters tall, and his strong body is like a wall, full of a sense of oppression from above, which makes it difficult to breathe. Suffocate for it.
