"But AFAIK there are no "Tokamak reactors planned that will be able to run continuously and produce useful power. These are all experimental reactors that will be self-sustaining for only a few seconds here and there. " But are there at least theoretical concepts, on how one could build a tokamak reactor that can run continiously? In other words, is the main disadvantage of the Tokamak solved in any way? If not, why is the Stellerator design not getting more attention?
