Chapter 393 Required Technology
"If we hand over all the magic-related technologies, they will relax the sanctions? Otherwise, they will intensify?"
Wang Yi, who had returned to the laboratory, couldn't help but find it a little funny when he heard the news relayed by Lin Shiqin.
But this does seem to be consistent with their usual demeanor.
Just start bluffing. If you succeed in bluffing, you make money. If you fail, think of other ways. Take it one step at a time.
To be frank, they want to stop the Rabbit 25 Plan and to be frank, they say that you cannot develop high technology and cannot get involved in high-end profits. These are really said in the clear and without any embellishment.
The ancient saying has always been to use "plunder by trickery" to describe it, but they don't even do the superficial work of "taking by trickery" and just "plunder" directly.
The same is true for Umbrella this time.
"Let's continue to waste time with them. How is the ammunition modification going?"
Wang Yi did not ask Lin Shiqin to reject the offer outright. He just dragged it out anyway. We will listen to whatever you say.
Time is on our side, so just keep dragging it out.
If a visitor from the abyss comes in the future, he will be thrown on your head and you will be asked to save the world.
That's what they say in the movies...
"It's already been done. All the Ka-28s have been equipped with new equipment, as have the previous batch of drones."
"That's good. The stability of the propellant and explosive here is almost there. If there is enough raw material, we can gradually replace them."
Wang Yi continued to carry out some verifications in front of the test bench.
The current level of modification has almost reached the point where Lin Shiqin can produce these two types of 'gunpowder' by controlling the magic machine tool without having to do it herself.
Cruise missiles have very high requirements for fuel due to their size and the amount of ammunition they carry.
Although aviation fuel can also be used as propulsion, if you want to go a step further, you will often use multi-ring high-density hydrocarbon fuels, high-tension hydrocarbon fuels, and add high-energy substances.
There is a difference between the propulsion of cruise missiles and that of rockets and ballistic missiles.
However, since they have already made the missiles themselves, Wang Yi certainly needs to optimize them.
Moreover, due to the limitation of the size of the available land in Penglai itself, Wang Yi also wanted to complete the unification of the corresponding "gunpowder" standards!
In other words, this type of propellant can also be used for other needs in the future.
This will naturally cause some trouble.
Finally, he chose a trinitro solid 'gunpowder' mixed with magic factor!
Depending on the mixing ratio and the oxidizer, this uniformly manufactured "gunpowder" can be used as either a propellant or an explosive.
Moreover, its power and performance are more than twice that of current competing products!
In fact, the original version of Wang Yi was developed a long time ago, but it was unstable and unsafe. After subsequent improvements, it has almost met the requirements for use.
"Oh, actually, we have enough defense force now. They are not asking about the propellant. ASML has already mass-produced a lot of EUV lithography machines that they have been holding back, and they have started to deliver them secretly.
"I guess the official announcement will be made after the first batch of debugging is completed, and my upgrade can be put on the agenda. Anyway, it's already in our territory, boss, come and help me upgrade yourself."
Lin Shiqin said this in a coquettish voice.
"Penglai already has an EUV production line. Just build it yourself. Don't ask me."
Wang Yi was speechless.
Lenses can be said to be the place where he first started. Even the principle of magic nuclear fusion was discovered while studying lenses.
The DUV lithography machine can be said to be just a "test the waters" product.
Why do we always use dry photolithography?
In fact, it is because EUV lithography machines cannot use the immersion method, and even EUV lithography machines cannot use the traditional dry method, but must use a "vacuum" environment.
Because extreme ultraviolet light is already ionizing radiation, it is enough to ionize the air, let alone liquids.
In this case, DUV is still used outside the base camp, but the EUV lithography system with lenses built by Wang Yi himself was originally used on Penglai.
The structure is quite similar to the previous DUV and it is a fully mature technology.
Unlike ASML's EUV lithography machine, which does not have a lens that allows extreme ultraviolet rays to pass through , it needs to use reflection, which results in extremely serious energy loss. Each reflection wastes about 30%, and ultimately only has a 2% utilization rate.
As the volume increases, the high power of the light source also requires a matching cooling system, which is almost equivalent to opening a completely new track.
So in fact, Wang Yi’s EUV lithography machine came out earlier, and its efficiency and yield rate are far superior!
"But they also have EUV, and the physical limits of silicon-based chips are almost reached. Boss, we need to upgrade~"
Lin Shiqin’s words also left Wang Yi speechless.
She should be able to understand that Wang Yi has certain limitations on her improvement in quantum computing.
After all, the exponential addition of quantum computing power, combined with Wang Yi's new formula algorithm, can easily lead to loss of control.
However, as the computing power of classical computers increases, Wang Yi will definitely not impose any restrictions on her.
The resolution of EUV lithography machine far exceeds that of DUV lithography machine.
The wavelength used is 13.5nm, which is close to the extreme ultraviolet light of X-rays.
Theoretically, the limit of silicon-based chips has been reached!
You have to know that a single silicon atom is only 0.12nm, and you also have to consider the electron tunneling effect, so the current normal view is that 1nm is almost the limit of silicon-based chips.
Of course, the tunneling effect had already appeared at 20nm and was solved through structural adjustments. Perhaps a solution will be found after the 1nm process.
But even so, the size of silicon atoms is 0.12nm, and it is impossible to separate the atoms.
In this case, what needs to be considered is either increasing the number of transistors by stacking the number of chips, adopting new architectures and new methods, or considering other materials.
For example, carbon-based is one direction, but there are too many problems to be solved in carbon-based technology and there are still many troubles.
In addition to this, there is another material whose computing power can exceed that of silicon by hundreds of times at the same density!
Moreover, because of its extremely low power consumption and almost no heat dissipation problems, it can be easily integrated and stacked in three dimensions, theoretically achieving efficiency that far exceeds the upper limit of silicon-based systems at the same scale.
That is the superconducting material formed by the Josephson junction.
Yes, quantum computers also use superconductivity , but the application of superconductivity in computers is not limited to quantum computers. Traditional superconducting computers also have corresponding structures.
It is only because of the cost-effectiveness and current low-temperature superconducting materials that we have only made single Josephson junctions for testing and have not attempted integration.
We all know that superconductors can be regarded as having no resistance and possessing anti-magnetic force. Normally, superconductors themselves cannot form the characteristics of semiconductors, but adding an oxide layer between two superconducting materials can achieve the same effect under certain conditions!
This is the Josephson knot.
It’s just that normally, superconducting materials themselves are too difficult to obtain.
In most cases, superconducting materials need to be in a low-temperature to have superconducting properties, and better ones need liquid nitrogen.
However, Lin Shiqin's intention was obviously to let Wang Yi make some room-temperature superconducting materials by himself to help her.
"Boss, the data calculations for the mass projector have been completed. To achieve the best results, I'm afraid it would be best to add superconducting materials. If you want to use traditional superconducting materials and add liquid nitrogen or even liquid helium refrigeration cycle devices, the volume and engineering workload will be greatly increased."
Lin Shiqin smiled like a little fox.
"Okay, I'll think about it and sort out my thoughts."
Wang Yi sighed and rubbed his forehead.
In fact, he had thought about superconducting materials several times. To be honest, he had used his magic power to actually pull out a small piece of room-temperature superconducting material, and it turned out to be a silver-copper alloy.
It can be said that it was purely forced out without considering the cost, and it seems a bit useless.
Because most places where superconducting materials are needed actually require a lot of them. Even the quantum computer in a certain song called "Planeta" uses much more superconducting materials than this one.
Not to mention the current mainstream controlled nuclear fusion tokamak device.
These are all assembled with a cooling circulation device that uses a minimum of liquid nitrogen, and some may still require liquid helium cooling.
But Lin Shiqin was right. If one wanted to create a mass projector within the parameters, the best magnetic coil material to use would be a superconductor.
If we don’t develop better superconducting materials, the additional cooling system itself will be a huge project.
"Boss, someone recently used diamond to pressurize hydrogen sulfide and achieved superconductivity at -70 degrees. I found the relevant papers and experimental results..."
When Lin Shiqin heard that Wang Yi was looking for ideas, she diligently sent him a lot of relevant information, which made Wang Yi feel somewhat interested.
Hydrogen sulfide?
Want to simulate the properties of metallic hydrogen? Diamond pressurization is indeed an interesting idea.
The other party used physics, and I can use magic to replace many places. If I follow the past, I may be able to achieve the goal of room-temperature superconductivity more easily...
(Note: The 2020 paper on room-temperature superconductivity under pressure was retracted, and there should be suspicion of fraud. However, another experimental team has demonstrated superconductivity in hydrogen sulfide at -70 degrees in 2015 and in lanthanum hydride at -23 degrees in 2019. However, diamonds need to be pressurized to a pressure of 1 million to 2 million atmospheres. It will probably take a long time for this experimental product to be of practical use in terms of pure physics, and it is not as convenient as liquid nitrogen superconductivity...)
