I like the idea of the passively-safe, waste-reducing LFTR but it's still a materials science issue at this point, and there's no real solution in sight.

Fission still has this huge stigma about "nuclear=dangerous and bad" which clearly isn't true with the growing number of passively-safe designs... but nobody wants to fund development of those into proper commercial reactors.

Meanwhile, fusion is still different and futuristic enough to have support from governments and the general public.

Seems ironic that in a thread about fusion with loads of difficult technical challenges that will still require decades of research after 60 years of investment and research have already been poured into it, a minor issue of slight corrosion in LFTR requiring maybe a few years of research is seen as an insurmountable obstacle with "no real solution in sight".

The solution may already be here, in the form of ceramics already used in aeronautics. A French startup is working on a small reactor for industrial heat with them.
