And they have promised investors that they will complete the 30-minute commitment before 2020.
Germany is known for its rigor, and the data they publish is likely to reflect the timeframe they believe they can achieve. Currently, internationally, there isn't much experience available for them to draw upon in this area.
In this area, the domestic situation has lagged behind for quite some time. However, Wu Tong is quite confident in herself. She feels that if she is given some time, she should be able to close the gap.
Since Germany has such ambitions, then her goal should be to achieve it earlier and for a longer period of time than the other party! Wu Tong secretly set a big goal for herself. Only with a goal can there be motivation, and only with motivation can there be direction for effort and output!
A journey of a thousand miles begins with a single step. Once a big goal is set, we should start from the progress of each step and improve the overall device.
Controlled nuclear fusion is a large project that covers all aspects, including technical difficulties ranging from plasma physics to material research and even information technology research... This is an extremely large project. Wu Tong planned it carefully and determined the pace at which they would gradually overcome it.
She currently has two major material problems that need to be solved. The first is superconducting materials, which are as close to room temperature as possible, or can be superconducting at room temperature. The installation process must be simple and do not require special setting conditions. The superconducting materials can be used to form superconducting coils that provide a huge magnetic field to confine the elusive plasma.
The second item is undoubtedly the reactor wall, that is, the first wall material. No matter how much the plasma is constrained, there will always be a small amount that cannot be constrained, which will bring neutron impact to the first wall. This requires that the material of the first wall must withstand the light and heat of the fusion reaction starting at hundreds of millions of temperatures, as well as the plasma impact that blocks the escape of the magnetic field. This requires them to have a material that is extremely resistant to high temperatures and can also withstand neutron penetration.
To be frank, Wu Tong was quite experienced in high-temperature resistant materials. After all, he had extensive experience in heat-resistant materials for fighter jets and missiles. It could be said that Wu Tong was a world leader in high-temperature resistant materials. Wu Tong had considerable confidence in developing materials in this area.
Both of these are material issues that must be overcome.
Materials that exhibit superconductivity under certain conditions are called superconductors. Superconducting materials are a hot topic in physics, and due to their important applications, they have been the subject of five Nobel Prizes.
Based on the material's response to superconductivity, it can be divided into type I superconductors and type II superconductors.
Based on their critical temperatures, superconductors can be divided into high-temperature superconductors and low-temperature superconductors. High-temperature superconductors generally refer to superconductors with a critical temperature higher than liquid nitrogen temperature (greater than 77K), while low-temperature superconductors generally refer to superconductors with a critical temperature lower than liquid nitrogen temperature (less than 77K).
According to the material type, they can be divided into elemental superconductors (such as lead and mercury), alloy superconductors (such as niobium titanium alloy), oxide superconductors (such as yttrium barium copper oxide), and organic superconductors (such as carbon nanotubes).
In recent years, organic superconductors have become a world-class research hotspot, driven by the continued inability of traditional elemental and alloy superconductors to break through their limitations. The study of superconductivity in graphene, with its rise to prominence, has become a highly promising research topic.
Wu Tong has recently focused on information in this area and has seen that as early as 2007, scientific researchers in this field published a paper on "Bipolar Supercurrent in Graphene" in "Nature". Wu Tong has consulted the literature and past information of the publisher and found that this research group has been continuously conducting research and development on this topic. They are conducting research on the superconducting properties of graphene materials under low temperature conditions.
This is a relatively novel research idea, which has opened up the research and development of organic superconductors and the superconducting properties of carbon nanotubes, which have begun to become the focus of researchers in this field.
Wu Tong wrote down the title of the research on superconducting properties of carbon nanomaterials on a piece of scratch paper. This was a good research and development idea. Wu Tong began to collect information in this area with great interest and conduct research and development.
In fact, the current hot research direction of superconductors in China is still mainly traditional superconductors, mostly elemental superconductors, oxide superconductors, and alloys. In the field of organic superconductors, there is a blank, and Wu Tong has no way to collect a lot of data. But this does not bother Wu Tong. It is very simple. If there are no conditions, then create them.
Lu Xun once said, "There are no roads in the world, but when more people walk on them, they become roads!" Her predecessors didn't leave enough foundation for her to stand on their shoulders and leap higher. So, it was up to her to be the pioneer, to cross the river by feeling the stones, accumulating experience and laying the foundation for future generations.
Designing different simulation experiments to screen the correct direction, Wu Tong could actually simulate and deduce many experiments in the deduction space. However, this would consume too much energy and the power of the enlightenment stele. Secondly, Wu Tong wanted to leave enough experimental data. Therefore, Wu Tong chose to design the experiment, which was a little more troublesome, and conduct it in the laboratory of the institute.
Thirdly, Wu Tong actually didn't want to overly rely on the Deduction Space if she had the means. This wasn't because she was worried about losing the Enlightenment Stele one day. Rather, everything in the Deduction Space was based on Wu Tong's perception of perfection, something she could easily achieve. However, in reality, she could master much more.
You know, many major achievements often come from accidental operations. The deduction space is likely to block the occurrence of such accidental miracles.
Repeating the research and development experiments on organic superconductors in the literature and top academic journals, designing experimental models and experimental processes step by step, trying step by step, accumulating various types of data step by step, and screening and improving step by step, Wu Tong's accumulation in the field of organic superconductors has also grown like a snowball with the passage of time.
When she was conducting research and development, she did not inform too many people in the institute about the information she was collecting. Therefore, the core members of the research team naturally knew that Wu Tong's next topic was superconducting materials.
This was a very important and popular topic, and they weren't surprised Wu Tong was interested in it. They remembered Wu Tong saying that after New Year's Day, they would launch a major project in the field of superconductivity. But regardless of whether it was, Wu Tong had already begun studying and researching it, even experimenting with it.
