    Explain why, please. I’m not an electrician, but as I understand it, when you install an electrical socket the same three wires in the romex cable provide power for both plugs. Effectively each of the holes in the top plug is bonded to the same hole in the bottom plug. So why would connecting them with an external wire cause a problem? Even if two outlets are right next to each other, and one has reversed polarity, you’d just be connecting neutral to neutral and hot to hot. I don’t understand why it’s a fire hazard.

    edit: last two sentences are wrong. If one plug has reversed polarity and one doesn’t you’d be connecting two wires from hot to neutral, and that would probably just blow a fuse.

    Literally? No. We’re all subject to the same laws of physics.

    Perceptual reality? World view? Yes. I only know one person in real life and not online (my wife) who shares some of my views of reality. For instance, I am a doomer. I am convinced we are well into the sixth, and by all accounts the most devastating, mass extinction. Humans are clever, but we depend on a stable environment for our food. That stable environment is turning into a series of alternating droughts, floods, fires, blizzards, and other extreme weather events. TBH, I’d be surprised if our species lasts to the end of the century. Hanson figures that, after feedbacks, we are on track for 10c of warming. That’s apocalyptic. And every time scientists talk about it you hear words like ‘faster than expected’. We are doing exactly nothing to prevent it, and are, in fact, accelerating the collapse by increasing our consumption, population, pollution, and environmental destruction. COP has been talking about it for so long (almost 30 years) that we’ve missed the boat. We are well past the point where we could stop it. We’re in the ‘find out’ stage now.

    Yet people keep having kids and planning for the future like everything is going to be just fine. Can you not see what’s happening? When’s the last time you scraped bugs off your car windshield? They’re all dying out. The biosphere is collapsing around us. But sure, keep contributing to your 401K. Keep talking about how the ‘fertility crisis’ is the big issue. Keep thinking that somehow windmills and recycling are going to save the planet. Tell me more about how voting is going to fix the problem. I feel like Kate Dibiasky saying we’re all going to die while everyone around me wants to talk about their PTA, the latest social issue, or which politician they like.

    (deep breath)

    Yes. I do feel like my perception of reality is different than most people I know. I don’t know most of humanity so I can’t really say, but it sure seems like it.

    I’ve done some blacksmithing as a hobby. The two most common ways of heating the metal are a gas or a coal forge. The coal forge normally has some sort of forced air coming from the bottom to feed the fire. The coal starts burning real smoky like, but then turns to coke and burns hotter the more air you force through it. Typically you pile some coal around the sides of the fire so it converts to coke then you scoop it into the fire as needed. Also it produces a waste product called clinker that builds up at the bottom of the fire at the tuyere (the nozzle or grate the air is forced through). It’s kind of like stone or metal and it needs to be cleaned out to keep the fire going.
