Would someone mind explaining how the suicide cord can kill grid workers?  I don't know if this is easier to understand in the US - we work on a ring main system in the UK, and (once it is plugged in and the prongs thus protected) I'm having problems seeing why it would be a problem even to the end-user (I suppose you could theoretically use it to connect a ring main rated for less current and set the walls on fire?)

Electrician here, Suicide cords are used to 'backfeed' a circuit. Homeowners make them when they are too cheap to add a generator outlet. When plugged in, one side has exposed live parts which can shock or kill you. The other danger is backfeeding the grid itself when plugging in a generator (hence lineworker danger) for the exact reason that line interactive inverters for solar arrays need to shut down when the grid is off. Line workers are expecting dead lines when they come down and backfeeding them may make them live on the ground or while the worker is holding them. The proper way to power a house is to have a generator outlet installed and an interlocked panel that disconnects the mains power from your panel (isolating the power lines) and connects the generator power to specific circuits you want.

curses, im too early on the scene for an explanation of what he's gonna do with the items in the titletext; such are the woes of being one of the people writing the explanations that you have to actually understand the comics - Vaedez (talk) 02:15, 24 January 2026 (UTC)

This is the third comic to reference the Demon Core experiment, after 1242 and 2593. Soupgirls (talk) 02:21, 24 January 2026 (UTC)

If you're otherwise creating fire hazards, a lithium ion battery is a terrible thing to have, and none of the horror stories you've heard involved a sack of them. Flour is a serious explosion hazard. Vinegar and bleach will release chlorine gas when combined. It sounds like an attempt to have the highest ratio of destruction to materials cost with the least effort.

The title text just sounds like a bunch of flammable/noxious substances. So really, he has good intentions. Tanner07 (talk) 03:57, 24 January 2026 (UTC)
