  • high latitude is sort of served by hydro because there’s lot of river per person in some of areas that are in any significant way populated (norway, russian north)

    medical isotopes are research reactor thing because of frequent loading/unloading - either that or some kind of channel reactors so either CANDU or RBMK. neither are exactly industry standard

    marine power requires small reactors = way more enriched than usual sub 5% = expensive and a lot of diplomatic noise about proliferation



  • renewable generation, i’m with you, but i’m not sold on storage. i’m not even sure if there’s enough lithium for grid batteries to seriously matter, so it might need to use something else. the boring, working option (geographically limited) is of course pumped storage hydro, but other than that, i think that the right way to do things is to use energy when it’s made, not when it’s needed. in particular, water heaters have tiny duty cycle and hot water just sits there, which means you could, in principle, make it so that water heaters soak up all, or at least as much as practical, of excess power, wherever it is available

    some countries do fund nuclear power as a kind of strategic energy independence hedge* no matter costs, most prominently france and russia, and to some degree india and a couple of others

    *also for military use















  • i don’t know, maybe softbank counted on openai not being able to go for-profit (which is not IPO, so it’s not like they got more transparent or anything). that deal was signed long time ago in bubble terms, and it went like this (or so i heard): first tranche was 10B from softbank + up ro 10B from other investors, they couldn’t get all that money from other investors and that’s why it was 18.5B and not 20B. that was some half year ago? even back then softbank didn’t had the money and had to sell part of arm (iirc). now they had to supply the remaining 22.5B, idk if it’s all softbank, or whether they would get out of that deal if they could, or whether they will continue pouring money there (we can assume all these dcs are vaporware) can openai find other suckers? possibly, but scaring away a reliable one would be bad for business
