I never heard about this, I'll save some lead for emergencies! |

There was another type of liquid diode too, used mercury held at a temperature where it was on the verge of evaporating. Its ability to rectify, and this was for distribution and railway level AC, not low voltages or 240V, depended on some sort of asymmetry in the direction that mercury gas and liquid droplets would move under applied voltages, might have been related to ionisation of them. |

Yeah I know mercury arc rectifiers :-+ |

I remember reading about something similar in an old book of electricity, but it was using a copper sulphate(?) solution. I can't seem to find that book at the moment but I did find this: On the Theory of the Electrolytic Rectifier (1902): https://ia800708.us.archive.org/view_archive.php?archive=/22/items/crossref-pre-1909-scholarly-works/10.1103%252Fphysrevseriesi.10.116.zip&file=10.1103%252Fphysrevseriesi.15.327.pdf |
