Chinese startup VeloAlpha uses AI to speed up fusion energy software

Chinese startup VeloAlpha, founded in April by fusion theorist Xie Huasheng, is developing FusionAlpha, a simulator that uses AI to test fusion reactor designs virtually before costly physical experiments. Xie argues that existing fusion simulation software faces an 'impossible triangle' of accuracy, speed, and reliability. Advances in AI and refined mathematical models have improved over a dozen physics design models, marking a turning point for the industry. FusionAlpha is likened to EDA software in semiconductors, where chipmakers optimize designs before fabrication. Fusion energy, which powers the sun, requires heating fuel into plasma and stabilizing it for sustained reactions.
