    The roadmap defines 3 milestone batteries. The first is released, it's a benchtop device that you can relatively easily build on your own. It has an electrode side of 2 x 2cm2. It does not store any significant amount of energy. The second one is being developed right now, it has a cell the size of a small 3d printer bed (20x20cm) and will also not store practical amounts of energy. It will hopefully prove though that they are on the right track and that they can scale it up. The third battery only will store significant amounts of energy but in only due end of the year (probably later). Current Vanadium systems cost approx. 300-600$/kWh according to some random website I found. The goal of this project is to spread the knowledge about Redox Flow Batteries and in the medium term only make them commercially viable. The aniolyth and catholyth are based on the Zink-Iodine system in an aqueous solution. There are a bunch of other systems though, each with their trade offs. The anode and cathode are both graphite felt in the case of the dev kit.

    Yep. Pretty sure that was deliberate on Musk's (or his cronies) part. Imagine working at X and being told by your boss "I'd like you to make the bot more racist please." "Can you convince it that conspiracy theories are real?"

    I played around the launch and didn't realize there were bots (outside of pve)... But I also assumed I was shooting a bunch of kids that barely understood the controls.

    Back in the day I just assumed everyone was lying. Or trying to get people worked up, and we called them trolls. Learning how to ignore the trolls, and not having trust for strangers on the internet, coupled with the ability to basically not care what random people said is a lost art. Somehow people forgot to give other the people this memo, including the "you don't fucking join social networks as your self". Anonymity makes this all work. Eternal September newbies just didn't get it.
