His first step is very large: $10bn up front to build one. No baby steps in between. I doubt it will happen. Certainly, if FF gets going, it won’t, because the massively centralized model of power generation will just go away.
I am very familiar with HIF. However considering that it never got close to fusion, and was only really experiment will on a small scale, his assertion that it will “just work” is weak. That’s what I mean by details. The details that matter for a *working* fusion plant. Not just one that “could” work “maybe” and by the way just give us 10billon.
