That's actually what we do, in this case: nuclear reactor-derived tritium is the *sole* source of helium-3.

It's *ten* times more expensive than gold!

(If I remember correctly, medical ³He MRI's are done on a closed rebreather -- they literally want to recycle your lung air, it's that valuable).

Indeed. I was assuming that the comment I was replying to was referring to helium in general because they were not more specific, and the normal form is ⁴He — we’re not filling party balloons with it.
