The tokamak has been the dominant design for fusion reactors for the past few decades, but recent advances in stellarator technology may soon relegate it to history.
Stellarators have several advantages over tokamaks, and many experts believe they are the future of fusion energy. These magnetic fields allow scientists to control the plasma particles and create the right conditions for fusion reactions.
