- gertlex 4y agoI think you and the parent poster may be talking about different "goals". My lazy quick skim of the main article here is that NIF has achieved a Q value of 1.2 presently. ITER is aiming for a Q of 10 [0]; i.e. Q=10 means fusion outputting 10x the input energy, which is (by some considered) roughly enough to break-even in energy production [1], i.e. to recapture 10% of that energy (as heat or as electricity, not sure...) So parent poster saying NIF is an order of magnitude away means Q=1.2 -> ~Q=10 And ITER seeking Q=10, means that's the goal that NIF is an order of magnitude away from, according to the parent poster.
