<radiobiology> Fusion will be considered scientifically feasible when (a) experiments are done which reach scientific breakeven-type plasma conditions (see entry on breakeven), and (b) the experimental results suggest that the approach can be scaled up into a power-producing system. Tokamak fusion reactors are closing in on (a), and tokamak researchers think (b) holds as well, so they are designing a power-producing machine (ITER) to demonstrate net energy production from tokamak fusion. Inertial confinement is also approaching this point.
