Dipole plasmas are inherently stable with no disruptions, and the risk that nature will throw some unexpected result at us is low. Instead, we have a reactor with interesting engineering problems to solve. We have achieved breakthroughs on many of our engineering problems, but still have a green field of problems worth tackling.
Unlike other concepts, the core components of a dipole reactor; the magnets, the chamber, and the heating system; are all decoupled from each other. This gives rise to a number of major engineering advantages over other fusion concepts.
