France has upped the ante in the quest for fusion power by maintaining a plasma reaction for over 22 minutes – a new record. The milestone was reached on February 12 at the Commissariat à l'énergie atomique et aux énergies alternatives (CEA) WEST Tokamak reactor.
We used very hot flame later. Still without full understanding of plasma.
I may have to yield this point to you as a demonstrated authority on not understanding plasma.
