Last week, Marathon Fusion, a San Francisco-based energy startup, submitted a preprint detailing an action plan for synthesizing gold particles via nuclear transmutation—essentially the process of turning one element into another by tweaking its nucleus. The paper, which has yet to undergo peer review, argues that the proposed system would offer a new revenue stream from all the new gold being produced, in addition to other economic and technological benefits.

any particle accelerator can do that just incredibly slowly.

Alchemy of that sort has been doable for generations, it's just WILDLY impractical!

Currently many orders of magnitude more expensive than just buying an equivalent amount of gold, but makes me wonder what the future might be capable of with those proofs of concept.

Science circling back around to alchemy is an interesting thought.

If it is possible to make small amounts of those elements on purpose as a byproduct, it can help to offset the costs of the reactor in some small way and help with isotopic/nuclear research in general. But that can be done in pretty much any fusion reactor design to some degree.

As for Alchemy of the future, If in a thousand years we can just built whatever materials we need (including potential ultra heavy stable elements) from raw subatomic particles we don't even need mining, just gather up some hydrogen/helium from space and transmute it into whatever you need. food, fuel, structures, etc.

And a gross of self-sealing stem bolts.

Humans sometimes run out of things to want.

I admit, it wasn't on my 2025 bingo card, either.
