  • ok i work in a kind of tangential industry and can kind of answer this probably

    in general the higher the voltage the smaller the current, which you’re generally happy about because your 1) electrical losses and 2) cable/wire diameter are both proportional to current

    the tradeoffs being 1) it gets harder and more important to isolate the circuit (e.g. your wire insulation that prevents the 12V bus from shorting out to the vehicle chassis now needs to be thicker) and 2) all the stuff people make for cars (i dunno, windshield wiper motors, radiator fans, whatever) is currently for 12V

    in general this move probably makes sense, provided they’re able to figure out their supply chains, and if tesla can position themselves as being like the first company to figure out a bunch of these 48V components at scale that’s probably going to be really good for them. they did a kind of similar thing with the charging infrastructure if i understand currently, like now the tesla charging cable is the de facto north american standard





  • it’s crazy that trump has basically trained us all to be able to understand him because he’s basically incoherent. in speeches he alternates between pre-written sections that he is clearly struggling to read, and completely thoughtless ad-libs like “many people are saying this” which he will say about literally anything. and in more spontaneous formats he’s just all over the fucking place, he just leaves a trail of sentence fragments behind him until he’s decided he’s talked for an appropriate amount of time. and his voice, i mean, he sounds like mark hamill’s joker after dental anesthesia. they should play his speeches on speakers mounted to the underside of cargo ships to repel whales
