  • I think hydro power storage is a good idea where it can be done (and especially where you have existing hydro power), but most places don’t have a giant reservoir nearby that could be used for this purpose. Something that I think could be a better option for widespread grid storage are flow batteries. These work by basically pumping an electrolyte solution back and forth across a membrane to store or discharge energy. They aren’t as energy dense as lithium batteries, but they have some advantages like being able to be used indefinitely without storage capacity degradation (though you do have to do upkeep on the pumps and whatever else). They’re already used in places like hospitals and for grid storage in China. These current flow batteries use vanadium, but there’s research being done on flow batteries that use iron instead, which is cheap and abundant in comparison.

  • You know what’s cooler than astrology? Ancient cults. I mean the kind of thing where a group or city state has a patron god/goddess and then they steal and subjugate the gods/goddesses of others. I don’t really believe in this stuff of course, but I just think it would be kinda cool to have a mascot to rally around and give us the courage we need to smite our enemies. Like, imagine if we had a cult based around Artimpasa or Inanna and then offered up transphobes, chuds, megachurch pastors, etc. to her as a blood sacrifice. That would be way more cool and useful than some astrology nonsense, and if I ever met another trans girl who was ready to brutally slay our enemies and fill the streets with rivers of their blood in order to bring honor to our goddess/cult, I’d totally be crush crush crush
