Marathon Fusion(@MarathonFusion):In 2025, we published a bold proposal to use fusion reactors for gold production. And now we’ve done it: Mercury transmuted into stable gold, using fusion neutrons, at 10x the record set by CERN in 2025. We’ve reduced alchemy to a series of difficult but tractable engineering problems.
