@Polfusilier The device in the bottom right is a mercury arc rectifier. It's used to convert high voltage AC to DC to power large electric motors. They have almost entirely been replaced by semiconductors/MOSFETs these days.
@Diogenese_Shiplap Gas arc rectifiers are beautiful pieces of heavy industry and are mesmerizing to watch operate. It may be a rabbit hole you'd be interested in.
@RegalBeagle @Polfusilier Good find. Sometimes I run out of ideas for a period of time. Others I scribbling ideas on napkins...
Headbangin' Christmas!
