  • I always find starting a conversation is hard without an ice breaker. Not necessarily something cheesy, but perhaps let’s talk about what general discussion forums already exist and what we like about them. There was often genuinely fun and interesting chat at AskReddit, "would you rather"is a good starter, and maybe we could have a “philosophy Friday” to get into the weeds on deeper topics?

    Alternatively we could discuss why “forums” annoys me. It should be “fora”, dammit!



  • If we were starting from scratch, iron is about as common as it gets, geologically, not to mention how much “leftover” iron and steel there would be, post collapse. Barium/strontium for sintering ferromagnets is trickier, but ores like witherite and baryte aren’t uncommon, though they are quite location specific, globally speaking. Not that you don’t actually need full blown permanent magnets, just ferromagnetic material.

    However, the easier (though less efficient) option would be to use dynamos with field coils instead of ferromagnets. That way the only resource you need is wire.
