Current flagship projects target a demonstration of net electricity in the early 2030s to 2040, which is still a prototype, not proof that fusion can be operated economically and continuously at grid scale over decades the way a fission or gas plant is. 1What Would Resolve ThisWell-attestedA named fusion plant delivering sustained electricity to a public grid on ordinary commercial terms (not a subsidized one-off demonstration), or an authoritative body such as the IAEA or a national fusion program concluding commercial fusion is or is not achievable within a stated decade. 1Discipline NeededWell-attestedPlasma physics and fusion engineering 1Question KindWell-attestedMechanism 1Question StatusWell-attestedOpen 1Reader FacingWell-attestedYes 1Open QuestionFusion research has produced real breakthroughs, but every credible timeline for commercial deployment has slipped for decades; World Nuclear Association itself notes the field's own standing joke that commercial fusion has been "about 40 years away" since the 1970s.
