Akito Takahashi commented on the laser fusion experiment that was in the news some months ago. I translated his comments. Then I had ChatGPT and translate.google.com translate them. ChatGPT is almost as good as a human. It almost could have fooled me, except for one or two words. translate.google.com made several mistakes. You can see it is a computer translation. I think it got the basic meaning correct.
ChatGPT made a strange error. It left out a parenthetical comment. I told it about that, and it generated a new version. It also said "neutral neutron" which a human would not say. Here is the ChatGPT translation. The part it left out in the first version is underlined: This is a laser implosion D-T fusion reaction with a COP of 1.2. As an experiment, it is groundbreaking because it exceeded the energy break even (COP=1). However, in order to implement it in society, it requires a technology that can repeatedly shoot multiple high-intensity beams (36?) of laser pulses with a COP>5 and synchronize the injection of DT solid pellets. Without this, it cannot be a power plant. The 14MeV neutral neutron from the DT reaction *(my old specialty)*, as well as technology to convert it into heat energy using a Li blanket, radiation damage and countermeasures due to neutral materials, and the proliferation of T (tritium), which does not occur naturally, are required. It will take decades to become a commercial reactor." (In short, the current situation is that there is exaggerated advertising for the budget acquisition of a large number of troops behind it.) Here is my correction to ChatGPT after the first version. This shows you can have a bilingual conversation: You left out this part: （私の昔の専門）, which modifies 14MeV中性子 Here is the translate.google.com version: One shot laser implosion D-T pulse fusion reaction at COP=1.2. As an experiment, it is epoch-making because it exceeded the energy break even (COP=1). For social implementation, high-intensity multiple-beam (36 ?) laser-pulses can be fired repeatedly at 10 shots per second with COP>5, and without the technology to synchronously inject DT solid pellets at the target, power generation reactors not. Technological development is required for the conversion of 14 MeV neutrons (my old specialty) in the DT reaction into thermal energy with a Li blanket, countermeasures against activation and damage of materials by neutrons, and growth of unnatural T (tritium). It will be several decades before it becomes a commercial furnace. (In short, the current situation is behind the hype to obtain a budget for the lives of a large number of troops.) My version: This is a laser implosion D-T fusion reaction with a COP of 1.2. As an experiment, it is groundbreaking, because it produced energy exceeding break even (COP=1). However, in order to implement this in a practical, commercial generator, we will need technology that can repeatedly shoot multiple high-intensity laser pulse beams (perhaps 36?) with a COP>5, synchronized with the injection of DT solid pellets. Without such technology, this cannot be used in a power plant. Dealing with 14 MeV neutron radiation from the DT reaction (my old specialty), will require extensive new technology, first to convert the reaction into heat energy using a Li blanket, and to deal with damage from neutron activation of the blanket material, and the proliferation of T (tritium), a radioactive material not found in nature. It will take decades to develop such technology to make this into a commercial reactor. (In short, the current situation is that this is exaggerated public relations puffery to obtain the budget from Congress, which must support the large number of researchers needed for this project.)
