First wall problems compounded by geometric constraints, fueling, magnetic & corresponding mechanical complexities, particularly over long periods of time where material fatigue sets in due to coils applying heavy, dynamic loading… there’s a lot against tokamaks.

They seem to impress people, and we could all use novel research into MHD. But @Blackdoomax@sh.itjust.works is kind of correct.

Tell me you don’t know what you’re talking about without telling me you don’t know what you’re talking about
