Nuclear fusion is the same process that powers the Sun and stars weforum.org – merging light atomic nuclei to form heavier ones and release enormous energy. In theory, fusion could provide virtually limitless, climate-friendly energy: it uses abundant fuel and produces little radioactive waste compared to conventional nuclear power. Unlike splitting heavy atoms, which leaves long-lived waste, a fusion reaction yields mostly harmless helium and short-lived neutrons weforum.org, euro-fusion.org. Recent advances have reignited a “fusion frenzy” – a global race among national labs and startups to tame the power of the Sun on Earth. Scientists, entrepreneurs and policymakers increasingly ask: could fusion finally revolutionize our energy systems? A Brief History of Fusion Research: Fusion has fascinated scientists for a century.
