Re: Bridge rectifier?
"These selenium rectifiers were notorious for the stink they made when they failed, which has been compared with a robot farting."
Everything in that column of the periodic table forms stinky compounds and reeks when burned. (Eg. sulfur, selenium, tellurium, and presumably polonium too)
If you're bored, google "tellurium breath". Apparently it only takes a very small exposure to tellurium to make the breath, urine, sweat, etc. reek horribly of garlic for a very long time.
