except for D/T (and D/D), most of other fusion reactions which don't involve exotic components (like He3) don't seem to be confine-able by the mainstream magnet

except for D/T (and D/D), most of other fusion reactions which don't involve exotic components (like He3) don't seem to be confine-able by the mainstream magnetic confinement (tokamak). The inertial confinement is starting to come back and with it the promise of the other reactions.
