Correct me if I'm wrong, but there haven't been "over unity" announcements before this -- aside from bombs. The Q of 1.5 here is the story. All Qs before have been under 1.
- whimsicalism 4y agoYou're right up to a delta of maybe some private companies claiming something which was false.
- AlanSE 4y agoHuh, ok. After some quick Googling, Wikipedia paints JET has having tried, and failed, to reach Q=1, only getting 0.67, which was way back in 1997. It's very strange to read that we get Q=0.67 in 1997 in a tokomak, and then Q=1.5 in 2022 with a totally different laser inertial confinement design. That... seems to be the written history. I know Iter would be surpassing the record, but the timelines are long to the point that one loses hope in the project.
