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.
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.
Tea, earl gray, hot.
And a gross of self-sealing stem bolts.
Believe it or not, this can actually be done without fusion alchemy.
It’s been explored in science fiction and I believe there are some actual theories and papers on the subject, but here’s the quick version:
The sun contains all the same elements found on earth in remarkably similar proportions (The exception being that all of earth’s hydrogen and helium were blown away long ago). But unlike earth, in the sun the heavy elements don’t separate and sink down to the core, everything just mixes together in one big suspension. Magnetic fields in the sun constantly eject charged particles out as solar wind and while these particles are mostly hydrogen, they actually contain every element found in the solar system. And because the particles are charged, this wind could be harvested using magnetic fields, it could be redirected and focused into a stream of matter for collection.
And it’s a lot of matter that could be collected this way… The sun loses 130 billion tons of matter in solar wind every day. For comparison, Mars’s moon Deimos masses about 1.5 trillion tons, so the sun loses a full Deimos worth of matter every 12 days. There would be more than enough of every element in that stream to satisfy humanity for the foreseeable future.
And my apologies for the long reply, someone mentioned space and I couldn’t help myself. 🤓
