Fusion Plasma Lasts 17 Mins — Why No Power Yet?

China's EAST tokamak set a 2026 record sustaining 100-million-degree plasma for over 17 minutes in high-confinement mode, yet scientists still cannot reliably achieve net energy gain or commercial viability.With global energy demands and climate goals at a peak in 2026, this breakthrough is shareable as both huge progress toward limitless clean power and a reminder of the stubborn physics b…
