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.
They say “artificial sun” because that’s what it is though, there’s no fusion reactions here they’re just microwaving hydrogen to millions of degrees to study the kind of thing that would happen IF somebody runs a fusion reactor for 22 minutes.
