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.
Huh, 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.
