Well Jerry what I'm f*cking talking about is in the last paragraph.

The poster is talking about carbon fibre and aluminium tripods and says
"they are a magnet for lightning". The poster then says "This problem is
avoided with basalt"

I realise you have a degree in metallurgy, but it may be worth pointing out
that basalt is mineral based, it doesn't conduct electricity.

Hope that's simple enough for a metallurgist to understood.
