What can I do with Iridium?

I'll trade you weight for weight with cast iron. Much handier.

Also worth around it's weight in gold (subject to large variations)...

Your hook is bent.

IIRC, it's worth several times its (an apostrophie does NOT mean "here comes an s") weight in gold. (I was looking at buying a small quantity to make a rocket engine)

Argh! The apostrophe police got me.. and I new that of coarse.

These guys say $110/troy oz, but from March this year, for purchase of the physical metal (which is probably going to be a fair bit more than the spot price).

Closing price on Friday was $87/troy oz according to the South African exchange.

This kid is a troll. He has posted similar silliness in various news groups.

Hmm. I wonder if I might have been thinking about Rhenium. (The current "gold standard" engine if you can afford it is a Rhenium coated Iridium engine (or is that the other way round), this gets all the cooling it needs to avoid melting by simply acting like a light-bulb, rather than needing cooling passages/...)

There has been some work on adiabatic ceramic engines for things like battle tanks. I don't know if any are currently in production.

Oops, rocket engine, not internal combustion.

Oh! Great! What we really, really, really need is a new troll!

I've learned a lot from trolls, A******, *ass, Ryker, etc, not so much from these dummys but from the replys from the group. Engineman1
