Are positrons classifie as Unobtanium? (They're antimatter, of course, so they're sort of covered already.)

The Asimov Robot books refer to them all the time, but I don't remember one where the story hung on a problem with them. So I guess they're not a Plot Device but (to use my favourite WS Gilbert quote) 'coroborative detail intended to add artistic verisimilitude to an otherwise bald and unconvincing narrative'.

[Prepares for flames from Asimov fans. Actually I like a lot of (early) asimov but I'm ambivalent about the robots.]

If any thing they are technobabble. it's not the positrons that are important it's the fact it's an artificial brain. the positrons are not a substance in the story just buzz word Prefix. I can say this as fan: If he was writing the books today he would be calling them higginstronic neuralnets or Quantum cyberbranes

About antimatter: "a microscopic amount = tactical nuclear weapon yield"

I would strongly debate that. I once heard, all particle accelerators on Earth combined couldn't even produce enough antimatter to ignite a match with its matter/antimatter reaction.

So, ...

the amount of antimatter all particle accelerators on Earth combined could produce = a microscopic amount

not able to ignite a match <<<<<<<<<<<<<<<<<<<< tactical nuke

You can have a microscopic amount of antimatter, which is still vastly more than has ever been produced on earth, and hence has a tactical nuclear yield.

Isn't this a bit wrong? I suppose unobtainium should be some exotic meterial like "red mercury" 106th element instead of stuff that is expensive but available.

Red mercury was fictional, references were created by the US/UK as a red herring to throw off other nations' development of fission, primarily the USSR.
