I wonder if the concept tested over the last 50 years, actually works, i mean ..the toroidal confinement (tokamak)....i wonder if it will work, is not the fusion research stucked with the same idea?

Any kind of for ultra-hot fusion confinement (not inertial) other than tokamak ?

I have my doubts about the ITER success

I think fusion reactors have reached for 1-2 seconds fusion energy output, but total brute energy output hasnt been achieved yet (meaning that the input power was still higher than the generated)
