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.
if I remember correctly, the output of a nuclear fission reactor can be used in a nuclear fusion reactor for a near-net zero loss in materials.
there’s like three different fusion reactors, so it’s likely one of the three that can do this, but still better than fossil fuels.
