What can normal temperature and pressure superconductivity do? This is a topic that has been talked about before the explosion of science and technology. It has been discussed or longed for for a long time, and can even be traced back to the first time mercury was exposed at a temperature of 4.2K
This was carried out until the moment when the resistance disappeared - since then, superconductivity has become a brand new substance, full of infinite charm and imagination, and is hailed by mankind as the Holy Grail in the field of materials.
The reason is simple. 0 resistance can eliminate losses in circuit transmission, can easily resist friction, can eliminate conductor heating in the circuit, and can obtain unimaginably powerful current to obtain an unparalleled magnetic field...
As a result, in the past hundred years, countless scientists have launched wave after wave of challenges to high-temperature and even room-temperature superconductors, constantly raising the critical temperature. Until five years ago, several types of superconductors have been discovered that can achieve superconductivity in liquid nitrogen.
"High-temperature superconductivity".
Then... it kind of died down.
Because of the emergence of two-dimensional materials, scientists have more and better choices. Science needs to be persisted, but science is never the best, especially when human beings face the crisis of collective extinction.
All scientific research must give priority to the military and serve weapons, which is the current situation. That is why Zhou Xiangnan, a two-dimensional material boss, will participate in the project of human super battleship.
But two-dimensional materials have a natural shortcoming, that is, their manufacturing costs are high, and this cost will not be solved in a short time. At the same time, it also has limitations, such as it is limited by the space state of the material.
It cannot carry out long-distance transmission and can only be used for short-distance structural superconducting - even in some cases, it is inferior to high-temperature superconducting in the liquid nitrogen temperature zone.
If the only advantage is that it does not need to consume and replenish liquid nitrogen, it can directly rely on energy to maintain the stability of the space state.
But in Ye Ming's eyes, the greatest significance of the room-temperature superconductivity realized by the Holy Empire is not the superconductor itself, but this magical "God-given steel" that assists superconductivity!
…
During the video conference, Director Niu, who was far away in the capital, asked first.
"What is the mechanism of God-given steel?"
"It's not very clear yet. What is certain is that it is a polycrystalline phase change metal that is sensitive to weak currents." After a pause, Ye Ming added: "Perhaps it is involved in the formation of superconductivity."
"Does that mean that God-given steel is not superconducting?"
"The current test results are that the specific mechanism needs to be analyzed in depth. The current guess is that the superconducting material in the middle generates a perfect superconducting phase with the participation of God-given steel. The superconducting material is a natural synthesis
of polycrystalline material.”
Following Ye Ming's introduction, General Qin, who was listening quietly, coughed slightly: "Mr. Ye, I don't understand these technologies... I just want to ask, can we get that god-given steel?"
?"
Ye Ming smiled and shook his head: "At present, it seems that it is not possible. This is probably a specialty of a certain planet."
"What about the superconducting material? I heard that they mined it."
"Well, I guess... the reason why the two Imperial people were able to confess is probably because they thought that these were collected resources, and we don't have the synthesis path or means."
As he spoke, a smile appeared on Ye Ming's lips: "These civilizations that have received 'system rewards' always underestimate humankind's technological foundation and technological routes... always think that everything is given by 'gods'... but they don't know,
As long as the crystal structure is analyzed, there will always be thousands of ways to achieve mass production."
Ye Ming's words made everyone smile.
As the exchanges with the Kerong people have become more and more in-depth and frank, the evolutionary labyrinth theory of the Kerong people has been widely spread in the human world and has gained great recognition - it is very simple! So far, humans have obtained
Is there any kind of god-given reward?
Absolutely not!
Unless you say that great scientists such as Niu Ye, Ai Ye, and Ye Ming are reincarnations of gods, and all achievements are given by gods. Otherwise, human beings have come to this step by step, all relying on themselves! Therefore, this theory is very consistent with the most important human beings.
Romantic conjecture.
And Ye Ming's sentence "Our reward is to walk on the right path" is even more recognized by those who know this theory, and even a little excited!
If the route is correct, then everything will be easy to say.
"So, compared to superconducting substances, what I am more concerned about is actually the phase change material called God-given steel. From the current point of view, it cannot be synthesized." Ye Ming said and looked at General Qin with a smile.
Although he didn't say anything, his eyes said everything.
Since it is only the planet where the Executor base is located, then...human beings may have to speed up their counterattack.
General Qin nodded slightly, then smiled meaningfully.
"Mr. Ye, when do you think we will be able to take the initiative to attack with our strength?"
"From a pure perspective of strength, we can now use rice grains and second-generation rice grains to complete a surprise attack on the enemy - they currently have more than 400 warships hoarding in the Ivan galaxy to confront us. These more than 400 warships
It belongs to the executive named Dika who sent us the message."
"But we also have reason to believe that since the 31st Execution Base has regarded humans as its biggest opponent, then the thousands of warships in their entire base will definitely be ready. If they are not pure idiots, they will not take all the
Show your strength - our scout ship is not blind."
Qin Weiguo nodded slowly: "You mean, if we want to fight, we can win, but we don't know what will happen next?"
Ye Ming blinked and laughed: "You are the commander-in-chief of the space fleet. It depends on how you command!"
"Hahahaha!" Qin Weiguo laughed loudly: "Good guy, you actually threw the blame on me - but Mr. Ye, our four major fleets have just been formed, and there are only about 300 battleships in total, and the mothership is also
I have just arrived in the Karatu system and have just started joint training with the Kron people, so I have no combat effectiveness. You ask me to challenge a force with a minimum of more than 2,000 warships... I feel guilty!"
Ye Ming coughed lightly.
Of course what General Qin said is the truth, but how can it be so in a war?
The current combat power situation and intelligence have made it obvious that mankind already has a combat power that surpasses the Executor fleet - this is not a numerical lead, but a generational lead brought about by technological improvements! If we really want to fight, one against ten and another
It's not impossible.
Of course, now that humans have such a small amount of wealth, they must still be cautious. They cannot just jump in when they see some advantages - the Chinese civilization that dominates mankind is the most strategically powerful civilization in the world, no one.
At this moment, He Mo, who had been listening to the recording, suddenly raised his head.
"Excuse me, I just received a communication request from Gloria."
When He Mo's voice fell, everyone was stunned for a moment!
The name of this Blue Star girl who was reduced to a Sin Descendant has long been spread among the top human beings. Even the leaders knew about it and specifically ordered to keep this hard-won seed. Therefore, CYN was specially established.
A dedicated department is ready to receive information from the other side.
Just for safety reasons, Gloria has only contacted twice so far. The first time was to contact humans, and the second time was to report the situation of the base fleet and ask for instructions on some tasks.
This is the third time.
After everyone looked at each other for a few times, Director Niu made a quick decision: "Come in directly!"
The next moment, Gloria's slightly blurry figure appeared in front of everyone's eyes.
"Hall has returned to his home planet, and they are moving reinforcements!"
The girl's voice had a hint of urgency, recalling that it was in everyone's ears.
