70-year-old nuclear fusion problem solved; can help tokamaks stop escaping electrons

SMRTR summary

Scientists have solved a longstanding problem in nuclear fusion research, developing a method to prevent high-energy particles from escaping fusion reactors. The symmetry theory approach enables faster design of leak-proof magnetic confinement systems for both stellarators and tokamaks. This breakthrough could significantly accelerate fusion reactor development, bringing us closer to abundant clean energy without greenhouse gas emissions or long-lived radioactive waste.
