  • Nuclear fusion reactors promise abundant, low-emission energy but face significant technical hurdles.
  • The Simons Collaboration on Hidden Symmetries and Fusion Energy, founded in 2018, aims to advance stellarator fusion reactor designs.
  • Fusion energy converts mass into energy, using abundant hydrogen fuel without direct carbon emissions, though sustaining reactions is challenging.
  • Stellarators use twisted external magnetic coils for plasma confinement, offering potential stability advantages over tokamaks, which rely on internal currents.
  • The collaboration combined expertise from plasma physics, mathematics, and computer science to optimize stellarator designs and develop open-source software (SIMSOPT).
  • A key achievement was proving quasisymmetry can be achieved precisely, enabling scalable fusion device designs.
  • The team established a common vocabulary and published educational resources, enhancing interdisciplinary communication and training.
  • Regular meetings, seminars, and summer schools accelerated research and fostered collaboration among diverse scientists.
  • The collaboration's work has spurred startups and experimental projects, advancing stellarator technology and launching scientific careers.
  • Future prospects for net-energy stellarators are optimistic, with predictions of viability within 10-12 years, backed by improved designs and tools.
