The jewelry and investment industries make up 45-50% of gold consumption. Practical and industrial uses make up only 5-10%.
As such, while flooding the market with cheap gold would rapidly lower value, that’s unlikely to be how the gold is sold. If the amount of gold being generated from fusion reactors is orders of magnitude less than the global consumption rate from jewelry and investment, which seems likely, and they are selling at our near market value rather than trying to undercut everyone, then the value of the generated gold would remain relatively stable.
in other words, considering that the gold market generates something like $350bn USD per year, and the total market value of “above ground” gold around $25tn USD, even if fusion reactors generate $1bn USD worth of gold it would have a negligible impact on the price of gold while providing significant value to the reactor operators (incentivizing the growth of the fusion reactor industry)





Homie, Au-197 is what’s being created, as stated in the screenshot, and it is the stable isotope of gold. It’s the naturally occurring one.
And the reaction doesn’t need to be especially stable on its own when it is a bonus byproduct of existing fusion reactor processes. The point is that we can take existing and new reactors, add this process, and immediately gain significantly extra value from the stuff we’re already doing.
it’s like hybrid electric cars that charge their batteries using the brakes. You’re already braking and losing a ton of energy as waste. ANY way to recapture and use that waste energy that yields more value than the materials required to capture it, is an immediate win.
