Right, fusion stops being a net producer of energy on atoms heavier than iron. A star’s fusion reaction ceases when too much of its core turns to iron.

Mercury is heavier than gold so it's a fission reaction.

Ah yeah, that slid by me.

Unfortunately gold generated in this way would be radioactive. They calculate they would have to store the gold for over 13 years to not require labeling as radioactive waste, or over 17 years to reach the level of radioactivity of a banana. I bet it would still be less valuable than regular gold even after that. It could still be identified, and people would discriminate against it. People are funny about nuclear wa…

This is not a problem for finance bros, they would sell a discounted note that gave you "ownership" of the gold in 17 years at some discount on the current spot price of gold. So you'd get these things that 'mature' in 17 years and you know their going to be worth whatever the spot price of gold is then, so it becomes a simple problem of pricing the risk that gold will be worth something in 17 years (people by gold f…

The treasury sells bonds that mature after X years. So I suspect something similar could happen. But further there could be refinement if the radioactive isotopes could interact chemically in ways that gold couldn't.

Then they could sell pure gold, and then hold the crap gold for 20 years and sell that later.

BTW, I was at Teardown.

I’d hold crap gold for retirement at a discount today

Imagine a whiskey manufacturer saying "this is impossible because we'll have to age it for 13 years" lel

Imagine a whiskey manufacturer saying "our whiskey is radioactive but it's ok because it will be less radioactive by the time you drink it!"

Skoal!

It requires mercury-198 as an input. The only quote I could find for mercury-198 is about $15K per milligram. So now we just need to figure out how to make mercury-198 cheaply.

It's 10% of natural mercury. you're looking into separating it cheaply instead, or at least hope the other naturally occuring isotopes don't cause too many problems.

If it's that easy to separate from natural mercury then it seems like they could make a fortune just separating it and selling the separated mercury.

Something isn't adding up

>In practice, given that much of all gold is used to store value and is not actively in use, we do not expect the need to store it for 7–17 years to be a major impediment; at worst, it means that the product will initially have somewhat less value than pure 197Au, and so some discount should be applied to the value of freshly produced gold.

You guys have a lot more faith than I do in people's ability to have rational beliefs about nuclear waste.

I agree with you, but people can also be very irrational about the value of gold.

Maybe there is not a huge need for isotopically pure mercury so the current price is not reflective of acquisition/manufacturing costs?

That thought fails altogether since it will do perfectly well sitting in a vault as a reserve for a 1:1 gold backed crypto coin. Of course this holds true only until its value collapses due to its lack of scarcity.
