my point in short is we don't have time for this right now. we need to de-carbonize our energy system a decade ago. this tech. is not operational and will take a decade to be so - that's not time we have to avoid catastrophic climate destabilization.
For most of my life fusion has been teased but not delivered. fission has been pimped for decades yet cannot get private funding, or build reactors in a decade, or provide solutions for the waste. Yet still the industries persist with their propaganda while renewables beat them in cost and time to operation. If I managed the funds I'd cut nuclear and redirect to wind and solar immediately.
If the governments using these these sorts of technologies are democratic, responsive, self regulating, have an informed populace, and lack of incentive problems. This is fine, but that’s a long chain of ifs.
