That's a bit like saying an automobile is not yet an automobile, because you haven't yet put gasoline in it. Wendelstein will fuse deuterium. (It won't produce net power, but we still call it a fusion reactor if it fuses atoms.)

I'm saying that calling an automobile a successful automobile before you have even put gasoline in it is premature.

The Wendelstein has so far been successful, and will likely perform fusion soon, but as yet it isn't a successful fusion reactor.
