The segment from Peter Diamandis’s Moonshots podcast highlights a major announcement by Marathon Fusion, a San Francisco-based nuclear fusion startup.
How the Transmutation Works
- The Physics: The company utilized fast neutrons generated from a deuterium-tritium fusion process to bombard mercury (specifically the abundant stable isotope mercury-198).
- The Reaction: Knocking a neutron out of mercury-198 transforms it into radioactive mercury-197, which subsequently decays into stable gold-197.
- The Milestone: Marathon Fusion claimed a production rate ten times higher than the previous record set by CERN.
They also noted parallel production of valuable medical isotopes (like copper-64 and copper-67 for cancer imaging and radiotherapy).
Broader Implications & Commercial Reality
- Economic Models: The startup previously modeled that a commercial fusion power plant blanket could theoretically produce tons of gold as a byproduct, potentially doubling a plant's revenue.
- The Caveats: The actual quantity of gold produced has not been independently verified, and freshly transmuted gold contains radioactive isotopes requiring years of cooling/storage before it can safely change hands.
Furthermore, the current reactor scale is minuscule compared to global mining output, meaning traditional gold markets remain entirely unaffected for now. - The Real Business: Beyond speculative "modern alchemy," startups in this space are leveraging fusion technology and plasma physics to find immediate commercial viability in high-demand fields like medical isotopes and advanced plasma centrifuges for isotope enrichment long before grid-scale fusion electricity becomes mainstream.
