- One of the unfortunate fallouts, IMHO, of the above reaction is that the
- Japanese plan to use Au as one of the active materials for catalytic
- convertors.
-
- This was conveyed by a researcher from GIRIO ( Govt. Instt... Osaka)
- who gave a seminar here on the topic.
-
- Economically, it makes sense - gold is cheaper today. However, in my
- opinion this is unfortunate. Gold has a charm like no other metal.
- Putting this in ceramic monoliths would make it practically irrecoverable.
-
- By the same count, I don't like the idea of Gold being used as a
- filler material for teeth. Unless it is removed after death, that gold
- would be taken off "circulation".
-
- In either of the above cases the quantity is substantial if numbers
- are taken into account.
-
- Next on the list : Gold as conductor for IC's.

- PS I know tons of gold have been buried in the high seas,but, sooner
- or later we'll find it and bring it back into circulation.
