Don’t you still need to spend energy on confinement? You don’t need to “reignite” the plasma but w/e confinement solution you chosen still has a cost and a non marginal one when it comes to magnetic confinement.

this uses inertial confinement rather than magnetic confinement.

You still need big ass lasers or particle accelerators for ICF too, these tend to be quite energy intensive too.

Yes, with ICF you do need to constantly reignite the plasma.
