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".
