Right. It is fun to keep plasma hot for a long time, but literally none of the fusion projects being worked on can ever lead to production of so much as one solitary erg of commercial power. Cost will necessarily be much more than for fission. Fission is far from competitive today, and falling farther behind daily. There is a bare possibility of eventual usefulness for spacecraft propulsion. And, some spinoff might come out of a newfound ability to handle lots of hot plasma. Maybe for sewage treatment?
