According to one I know who has actually bothered to watch the film it contains roughly this:
But at one point, there’s a tech billionaire (a version of Bezos or Jobs) who says that instead of destroying the asteroid, we can mine it for all the expensive rare minerals and it’ll be worth trillons. Something about yttrium, terbium, osmium, dysprosium and how we’re running short and the asteroid would contain 32 trillion dollars of it
Now, I’m going to have a very rough guess here. Osmium is fun, last time I saw – mebbe a decade back – possibly 500 a troy ounce. But a small market mind. Yttrium, $50 a kg for the oxide sounds about right. Hundreds of tonnes a year at tops. Dy is $couple of hundred, Tb $sixorsevenhundred a kg. 100 to 500 tonnes of each mebbe?
Not that I’d stand by those prices but they’re right range, so are market sizes. What the hell, call it all $250 million a year. So, someone drops 120,000 years of supply onto the planet in one large refinable lump. OK, let’s assume drops gently.
Prices just aren’t going to hold up, are they? Therefore the $32 trillion isn’t true either, is it? Prices, as we all should know, being reliant upon both supply and demand.
