Demon School

Hearing Guo Zhenyu asking questions like this, Liu Guangming couldn't help being nervous, wondering if he would make Ma Yang dissatisfied with such a hasty question, could not help kicking him lightly under the coffee table.

Guo Zhenyu didn't seem to understand what he meant, and murmured, "If I hadn't figured out what this thing is, how would I do my job?"

"Of course, we will definitely let you know!" Ma Yang said with a smile. He took a recipe from Guo Zhenyu and said, "This is a recipe for a new room temperature superconducting material. According to the data obtained from our experiments, This material can achieve superconductivity between 252.3k and 314.2k! "

k refers to the sign of Kelvin temperature. Unlike the temperature measurement of Celsius, which defines the temperature of the ice-water mixture as 0 degrees, Kelvin defines the absolute zero degree as -273.15 degrees Celsius as the starting point of calculation. The temperature has become 273.15k. Each 1k change in temperature is equivalent to a 1 degree change in temperature.

After conversion, we can know that between 252.3k and 314.2k that Ma Yang just mentioned is equivalent to minus 20.85 degrees to 41.05 degrees Celsius, which is basically equivalent to the temperature of room temperature!

"Minus 20.85 degrees to 41.05 degrees?" Guo Zhenyu also quickly calculated the results, he was not only frightened, "I remember that the highest level of superconducting materials in our country is only superconducting at 153k? Are you sure you The test data are real? "

153k is equivalent to minus 120 degrees Celsius. If you use such a material as a cable for power transmission, you must install a pump and cooling equipment every one thousand kilometers or so, using a cooling agent like liquid nitrogen to keep the temperature of the cable at minus 120 degrees Celsius The following greatly increases the cost and complexity of the superconducting cable solution; so although the superconducting cable can reduce the loss of thousands of kilometers of electrical energy to a few percent of the existing level, it is also due to the high cost of maintaining the cable Unable to get application.

The formula that Ma Yang has come up with is not simple. Immediately raised this record by more than one hundred k, minus 20.85 degrees to 41.05 degrees temperature range, except for some extreme regions. This temperature is basically equivalent to the local ground temperature! This means that superconducting cables can be used for long-distance power transmission without cooling! Will greatly reduce the cost of power transmission. The annual savings for the country will be hundreds of billions! This will undoubtedly be a landmark invention in the history of human science and technology.

"We have gone through many tests, and the results have been confirmed to be correct!" Ma Yang could hardly believe his eyes at the time, but no matter how the experimental conditions were changed, the performance of this material was consistent. "There are also some samples in the box, you You can verify it by yourself! However, you must pay attention to confidentiality! "

"I now understand why you are so cautious!" Liu Guangming's face was excited. "It is no exaggeration to enhance the level of confidentiality with such advanced technology! By the way, I don't know how much the production cost of this material is. ? "

If the price is higher than gold. So this material is the meaning of large-scale application. As an entrepreneur, Liu Guangming is most concerned about cost.

“It ’s the current generation product, and the price is still relatively high! So it ’s probably unrealistic to use this material as a transmission cable in a short time!” Ma Yang also felt quite regretful, “but our researchers have already begun After researching the second-generation products, we have a perfect theoretical reserve, plus the current foundation! After some time, alternative products with lower prices can be developed! "

"Huh, this is a Nobel-level achievement! It's a pity to keep such a secret!" Guo Zhenyu said regretfully from the perspective of a scientist.

"It doesn't matter, as soon as we research a cheaper alternative. This material can be put on the market! Secondly, Professor Lu has already won the Nobel Prize! The difference between once and twice Not so big! "Hey, coach. I also want to win the Nobel Prize.

As soon as this statement came out, both Liu Guangming and Guo Zhenyu were speechless at the same time. If any scientist can get a Nobel Prize nomination, it is enough to become a legend, let alone winning! Almost any achievement that can be nominated is the crystallization of the scientist's hard work. Now that Lu Qiujian has won the award only a few years ago, he has come up with a new award? Does this make other physicists alive?

After a long silence, Guo Zhenyu first recovered, and he asked curiously, "Don't Professor Lu preside over the exploration of the space exploration program? How could he do superconducting materials?"

"Superconducting materials are also widely used in aerospace! The anti-gravity effect of superconducting rocket launchers can greatly save the cost of rocket launches. If the cost of materials is reduced to the point that they can be applied on a large scale, we can even use them directly. The vacuum superconducting pipeline will send the spacecraft directly into space! In addition, superconducting satellites have a longer service life and more powerful functions than conventional satellites ... "Ma Yang talked about superconducting technology in aerospace. Widely used in the field.

But in fact, Lu Qiujian did not intend to use these materials as superconducting rocket launchers and superconducting satellites. Instead, it is intended to be used for the magnetic confinement of plasma. Www.readwn.com ~ The magnetic field that confines the plasma is generated by the coil outside the vacuum chamber. The current can generally reach tens of thousands of amps. If you use conventional copper conductors, the power will reach the level of megawatts, which is equivalent to the power generation of a generating unit of a thermal power station. You can calculate how much heat will be generated in one hour and will be generated in one day. How much heat, all of this heat needs to be taken away by the cooling water in time ... such a cost is too high!

Once full superconductivity is used, the coil resistance is 0, and after the coil current is increased to the specified value, theoretically no more energy is consumed, and the time for maintaining the fusion can theoretically be infinitely long. This feature is a controlled nuclear fusion in the future. Necessary for commercial application.

Just like the iter that Ma Yang visited, their confinement magnetic field was intended to be produced using superconducting magnets, but the materials they used were far from the level of this material. Cern's lhc collision pipeline is also composed of superconducting coils. Like iter, they need to use a large amount of liquid nitrogen to cool the superconducting coils to more than two hundred degrees Celsius, so that the coils can be superconducting.

But now it is different. The materials used by Xi and the project can directly achieve superconductivity at room temperature, which means that they are one step closer to the commercial application of controlled nuclear fusion. (To be continued.)

ps: It's a black technology.
