China’s Private ‘Artificial Sun’ Clears New Milestones as Start-ups Race to Commercialise Fusion

Energy Singularity’s HTS tokamak, Honghuang‑70, has achieved successive long‑pulse plasma runs — culminating in a 1,337‑second steady state — demonstrating engineering reliability in a privately built device. The results strengthen China’s private fusion push amid rising investment and new national law support, though net energy gain and reactor‑scale engineering remain unresolved challenges.
