  You made 10+ comments along those lines, just for this article. How about providing at least some justification, rather than making absolutist statements?

    DT fusion has inherently lousy volumetric power density. ITER's thermal power density, for example, is 400x worse than a commercial pressurized water reactor's primary reactor vessel. ARC's is 40x worse. Now couple that with those cores being far more complex than a fission core, and the difficulty of maintenance (they will be too activated for hands on maintenance.) IMO, the only fusion company that has a real chance is Helion. Most of the breathless hype runs into generic showstopping issues like the ones above. If someone presents a new fusion concept, ask them about their power density, and how much complexity there is in that core.
