  • you don’t need a lot of computers there, it all can even work without communication with power company. on medium voltage (15kV) lines, that would be reclosers every few kilometers, and these do trip when short to ground (>0.5A) is detected. but no one does that on low voltage, because potential for damage is much less. the difference between euro and american grids is that americans have medium voltage line going down every single street, and because of low voltages and high power draw conductors would have to be of monstrous size otherwise. i understand that GFCIs are rather uncommon out there, and these aren’t usually installed in substations either. there are also lots of smaller transformers in american grid and that would make costs of putting all that protection circuitry even higher (in my home village there was 1 15/0.4kV substation per some 250 people, or 80ish houses. americans can have one transformer per one house) gas line could be plastic, so it would be isolating and so it’d be limited to that one house


  • that sounds pretty dangerous and i’m not sure if it would even work, because for it to work it requires line to get shorted somewhere else with better ground resistance, tripping breaker at substation. if it fails, you have now high step voltage on the ground and not just near water pipes underground. or it requires line to be cut, and to be sure you’d need to hit all 4 (euro) or 3 (american) wires or insulators. or you could try to pull out fuses at substation, (with insulated tools, on low voltage side) at least for these that i’ve seen it’s possible (like this one https://www.sonepar.fr/catalog/fr-FR/products/05584019458). if fuses are bolted on tho, shit outta luck. (no idea what americans are using)

    e: the more i read about american electrical code, the more horrified i get. you can get mains voltages of 120v phase-neutral, 208v phase-neutral, 208v interphase, 230v interphase, 240v interphase, 240v phase-neutral, 277v phase-neutral, perhaps 416v phase-neutral, 480v interphase, or perhaps 480v phase-neutral. of which 277v and 480v are for business customers only? (and 347v, 600v in canada)

    this can only be a result of plug manufacturers conspiracy

    High-leg delta (also known as wild-leg, stinger leg, bastard leg, high-leg, orange-leg, red-leg, dog-leg delta) is a type of electrical service connection for three-phase electric power installations. It is used when both single and three-phase power is desired to be supplied from a three phase transformer (or transformer bank)

    if you want to supply both three-phase and single-phase, supply three-phase as symmetric three-phase + neutral and supply single-phase as phase-to-neutral. it’s simple, it’s sane, it’s standardized, and it’s efficient in copper. that way nobody needs 200A circuits, 7kV transmission line running down every damn street and substation every 5 houses because all high power loads are three-phase, that also means no large imbalances in load happen

    it looks like end result of decades of penny pinching managerialism with zero planning for any standardization




  • according to that reddit post, during a storm power line fell on gas meter, energizing gas line. now, that means that current flows bypassing meter and breakers entirely, going to ground via gas line, glowing flex, then water pipes and/or neutral. normal breakers won’t trip, because neutral does not have breakers. GFCI should trip, but it does nothing to stop gas pipe from glowing because current that heats it doesn’t flow through there. to unfuck this particular situation you’d need to trip breaker at substation, or disconnect power line going to that area

    gas line could be shut off in principle, but it’ll be energized, so it’s not an option






  • i don’t think it captures entire picture. it’s pete thiel, self hating gay rubbing shoulders with nazis, vanquisher of gawker, surveiller of facebook, all-seeing eye of DoD and so on and so on, at some point figured that he’s 50 and won’t live forever, and this made him scared. it made him so scared that he bought into transhumanism hook line and sinker, wants to be frozen in liquid nitrogen when that motherfucker finally croaks, but he’s also afraid of that, so he also bought into untested life-extension and performance-enhancement supplements as well. because no sane ethical board would allow for clinical trial for these (and it’s obviously 1984, not like it would be in his imagined libertarian cyberpunk future) he made enhanced games as a means to source willing participants, so that he will take some of these scam pills only after these are tested on the poors (by his people)
