why 43 seconds, you say…

“Fusion reactions were sustained at high performance levels for 43 seconds, which is a major breakthrough in plasma physics.”

hasn’t it already been done for longer?

edit: Okay it’s a different kind of reactor, that makes sense.

I wonder who will win this nuclear fusion race: the United States, Europe, or China?

Surely ITER is our best bet at this point amongst the current reactor plans?
