> With ICF, MCF, and MTF, and many instances of those classes of fusion machines being constructed and tested globally, there is a path and plan to make nuclear fusion viable in the future. Doesn't matter that the first machine costs billions, the price will come down at each every subsequent iteration You could have made the same argument about nuclear fission. Fission energy has been viable for decades, and yet we still don't have free energy. You didn't give any reasons why it would be different for fusion. By the way, your reasoning is flawed: From your assumption that initial prototypes are expensive (which is valid), and the assumption that subsequent commercial designs will be less expensive (also most likely valid), you conclude that it will eventually be so cheap as to be essentially free (definitely invalid conclusion, with lots and lots of counterexamples).
