Fang Ping nodded and left the new materials laboratory.
The main reason why Huang Junjie doesn't want to get entangled with the villagers is that if it continues like this, it will not be beneficial to both parties. Once it is hyped up, it will be another troublesome matter.
After all, online violence is difficult to explain clearly. People will subconsciously sympathize with the weak, because most people are from the middle and lower levels, and their hatred of the rich is subconscious.
Instead of wasting time getting entangled with the villagers, it is better to find a new place. Anyway, there are many places suitable for establishing wind power stations in the coastal areas, so why bother to build a boat there.
After Fang Ping left, Huang Haojie continued to return to the laboratory and was studying iron-silver superconducting alloys.
In fact, Iron-based superconductors were developed by Sunlanders in 2008, and have since been extended to a series of Iron-based superconductors, which are mainly divided into four categories.
Before iron-based superconductors, there were copper-based superconductors. In 1986, scientists discovered the first high-temperature superconducting material, lanthanum barium copper oxide. Since then, copper-based superconducting materials have become a research hotspot among physicists around the world.
.
However, until today, the physics community has not reached a consensus on the high-temperature superconducting mechanism of copper-based superconducting materials, which makes high-temperature superconductivity one of the biggest mysteries in condensed matter physics today.
Therefore, many scientists hope to find new high-temperature superconducting materials in addition to copper-based superconducting materials, so as to make the mechanism of high-temperature superconducting clearer.
Just in February 2008, Sunland scientists first reported that fluorine-doped lanthanum oxyiron arsenic compound has superconducting properties at a critical temperature of 26 Kelvin (minus 247.15c).
On March 25, a scientific research team led by Chen Xianhui of Dongtang University of Science and Technology reported that fluorine-doped samarium iron arsenic compounds also become superconductors at a critical temperature of 43 Kelvin (minus 230.15c).
On March 28, a scientific research team led by Zhao Zhongxian of the Institute of Physics of the Dongtang Academy of Sciences reported that the high-temperature superconducting critical temperature of fluorine-doped praseodymium oxyferrite arsenic compounds can reach 52 Kelvin (minus 221.15c).
On April 13, the scientific research team made a new discovery: If fluorine-doped samarium iron arsenic compound acts in a pressure environment, its superconducting critical temperature can be further increased to 55 Kelvin (minus 218.15c).
In addition, a scientific research team led by Wen Haihu of the Institute of Physics of the Eastern Tang Academy of Sciences also reported that the superconducting critical temperature of strontium-doped lanthanum oxyiron arsenic compound is 25 Kelvin (minus 248.15c).
Iron-based superconductor is a superconducting material based on iron-containing compounds whose superconductivity is mainly dominated by 3d orbital electrons in the iron element.
It can have high-temperature superconductivity above 40 Kelvin. Superconductivity occurs in the iron-arsenic plane of a quasi-two-dimensional crystal structure. Research on it can help reveal the mechanism of high-temperature superconductivity.
Of course, both copper-based superconductors and iron-based superconductors have weaknesses that are difficult to overcome.
The high cost is one thing, after all, problems that can be solved with money are not problems.
However, these superconductors have a fatal weakness, that is, to maintain the superconducting state, they must be in a low temperature state.
What we often hear about low-temperature superconductors and high-temperature superconductors is actually a relative concept.
High-temperature superconductors are a type of superconducting material that have general structural characteristics and relatively moderately spaced cuprate planes. They are also called cuprate superconductors.
High-temperature superconductors are not the high temperatures of hundreds or thousands of people as most people think. They are just much higher temperatures than the original ultra-low temperatures required for superconductivity, but they are also around minus 200 degrees Celsius.
In the superconductivity studied by humans, the temperature has increased significantly, so it is called a high-temperature superconductor.
But even for so-called high-temperature superconductors, in order to maintain the superconducting state, liquid nitrogen must be continuously refrigerated. Not only is the maintenance cost very high, but the process is also very difficult.
Therefore, the concept of room-temperature superconductors came into being. Room-temperature superconductors, also called room-temperature superconductors, are materials that can exhibit a superconducting state without the need for low temperatures.
Like Pandora in the movie "Avatar", those floating lands contain huge amounts of superconducting ore.
He had previously obtained the "Iron-Silver Superconducting Alloy Technology" from parallel time and space, but at that time the completeness of this information was only about 40%.
After more than a year of accumulation, he raised the completeness of "Iron-Silver Superconducting Alloy Technology" to about 87 from the memory fragments of parallel time and space.
Although the completeness of "Iron-Silver Superconducting Alloy Technology" has been improved to 87, he felt unable to start looking at this information.
Because the manufacture of iron-silver superconducting alloys requires three conditions, which are large-scale x-ray lasers and low temperature and high pressure.
According to the technical design, the power of large-scale x-ray lasers needs to reach 1 million kilowatts, which is the minimum standard. If you want to achieve large-scale production, the power must reach 5 million kilowatts.
Seeing this is simply deceiving. What is the concept of 1 million kilowatts? It is equivalent to consuming 1 million kilowatt hours of electricity in one hour, 24 million kilowatt hours of electricity in a day, and 8.7 billion kilowatt hours of electricity in a year.
This is still at the laboratory level. If we want to achieve large-scale production, we must increase the laser power to 5 million kilowatts, which is the starting position.
Think about 5 million kilowatt-hours of electricity consumed in one hour and 43.8 billion kilowatt-hours of electricity consumed in a year.
How much iron-silver superconducting alloy can be produced after consuming huge amounts of energy? About 400 tons.
On average, one ton consumes more than 100 million kilowatt-hours of electricity. This does not include other costs. Including other costs, one ton of iron-silver superconducting alloy costs no less than 50 million Chinese yuan, and one kilogram costs more than 50,000 Chinese yuan.
What's even more deceiving is the 5 million kilowatt x-ray laser. The cost of this thing is no less than 6 billion Chinese yuan. Including other supporting facilities, the total cost is initially estimated to be about 10 billion Chinese yuan.
If we really want to produce on a large scale, the annual electricity bill will be about 13 billion yuan.
In addition, the silver content of the iron-silver superconducting alloy itself is about 21.
The current industrial silver price is about 4.2 Chinese yuan per gram, and one kilogram is about 4,200 Chinese yuan. For 400 tons of iron-silver superconducting alloy, according to the silver content of 21, 84 tons of silver will be used, which will cost about 350 million Chinese yuan in total.
If large-scale production, for example, drives up the price of industrial silver, the production cost of iron-silver superconducting alloys will be forced to increase.
Room-temperature superconductors costing 50,000 yuan per kilogram can only be used in high-end products or laboratory research.
Such as nuclear fusion and superconductor chips. As for superconductor power transmission, don't even think about it. Even if Melician launches normal temperature superconductor power transmission, it will go bankrupt.
Think about the cost of 50,000 yuan per kilogram. How much does it cost to make a kilometer of transmission cable? One meter of high-voltage wire is about 10 kilograms, and one kilometer is about 10 tons.
Just a single kilometer of high-voltage wires costs 500 million yuan. Think about how many kilometers are needed across the country? The price is so impressive that even the five gangsters can't afford it, let alone those weak chickens.
However, even if the cost is high, Huang Haojie still decided to launch this super project. After all, lighting up room-temperature superconductors is related to superconductor chip nuclear fusion.
If nuclear fusion can be pointed out, the cost of power generation will drop to a few tenths of what it is now. The drop in power generation cost means that the production cost of room temperature superconductors will drop, thus forming a virtuous cycle.
Of course, room-temperature superconductors are just one of the conditions for nuclear fusion, and Huang Haojie didn't expect to create one in a short time.
But iron-silver superconducting alloys must be developed.
