Which part is wrong? The "self-sustaining nuclear fusion" that just succeeded last year, all experiments have failed this year
This is a tricky and frustrating question. Researchers from the Lawrence Livermore National Laboratory in the United States said that in the experiment last August, they successfully achieved "self-sustaining nuclear fusion", which is definitely a huge breakthrough on the road of mankind's search for new energy. However, since January this year, scientists have conducted a large number of repeated experiments, trying to prove that humans have achieved "self-sustaining nuclear fusion". However, until now, all repeated experiments this year have ended in failure. Which part is the problem? Why can't the experiments that were successful last year fail this year? Is it really as people speculate: Was last year's experiment just a "coincidence"? What is "self-sustaining nuclear fusion"? To put it simply, the fusion temperature is high enough that the atomic nucleus can continue its self-fusion reaction from the moment it is ignited without the help of external force. At this time, as long as new tritium can be continuously input When it comes to the physical strength of the reaction, then controllable nuclear fusion can be realized, which can always provide stable energy output for human beings. Speaking of which, since the Industrial Revolution, human activities have caused serious damage to the earth's climate and environment. Therefore, in order to protect the earth and allow human beings to exist on the earth for a longer time, as early as a hundred years ago, some scientists called for human beings. Find a way to find "friendly energy" that will never run out, so that human beings don't need to worry not only about the climate, but also about the lack of energy. As a result, "controllable nuclear fusion" has been highly hoped by scientists and is considered to be the key to the transformation of human resources. What is "nuclear fusion"? It is to use human science and technology to replicate a "sun" on the earth, and to continuously obtain energy from internal combustion by simulating the operation of the sun. So how did the "self-sustaining nuclear fusion" experiment succeed last year? Speaking of which, as early as 1955, physicists found the key to the experiment, when John Lawson created a set of ignition standards, which is also the "Lawson's formula" that scientists have been using for reference in the study of nuclear fusion. "Ignition Criteria" can help experimenters identify exactly when the ignition in the nuclear fusion process occurs. The American scientists who achieved successful experiments last year also referred to this ignition standard, and successfully completed 9 kinds of experimental acceptances last year. Obviously, last year's "self-sustaining nuclear fusion" was very successful. For example, in February last year, the scientific research team successfully achieved the combustion of plasma, and then on August 8 last year, if there are no accidents in this year's experiment, then this day is definitely a milestone for human beings. According to the experimental report at the time, after the scientists successfully ignited the plasma, the plasma continued to burn in the fusion reaction with no external force at all, and the temperature remained well. However, so far this year, the research team has carried out 4 repeated experiments, but the best one has only reached 50% of the successful experiment last year. In this regard, some researchers believe that it may be because ignition Sensitivity requirements are extremely high, and many small differences that are not easy to detect may lead to experimental failure. To put it bluntly, it is "a thousand miles away", which also means that the success of the experiment in August last year is still very far from human beings who have really mastered controllable nuclear fusion. After all, at least now scientists can't replicate it perfectly The experiment at that time also seemed to show that the success of the experiment last year did have a lot of luck in it. Is it true that humans will never be able to achieve controlled nuclear fusion? Scientists call nuclear fusion "a bonfire" ignited by mankind on the earth, but it will never go out, which means that mankind has truly achieved success, and it can also provide mankind with a steady stream of clean energy. any pollution and impact on the environment. But when will it be realized? 100 years ago, the answer given by scientists was 50 years later, and in the middle of the last century, the answer was still the same, including at the end of the last century, scientists also believed that human beings would achieve controlled nuclear fusion in the middle of the 21st century. So, 50 years and 50 years, is it going to go on in an infinite loop? In fact, this is not the case. Take the self-sustaining nuclear fusion experiments at the Lawrence Livermore National Laboratory in the United States this year. Although they all failed, it is not that they have not mastered the technical principles of operation, but they cannot be perfectly reproduced. So, maybe a little more time, these problems can be solved. How long will it take? In this regard, American researchers believe that it will be about 30 years later, friends, what do you think? Do you think that in another 30 years, human beings will really be able to achieve controlled nuclear fusion? Welcome to leave a message and tell us your opinion!
