    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.

    My first set I made myself. The "blackout" backing was white. The curtains themselves were blue with horses I think (I was like 8). I later used the backing with some Star Wars sheets to make new curtains.

    Weird headline. Is it the city making this recommendation, or the... Despite universal opposition by the dozens of residents present at the meeting, commissioners voted to recommend changes to the city’s zoning laws to allow data centers in areas zoned for light industrial use and to rezone a 700-acre property from agricultural to light industrial to accommodate the construction of a hyperscale data center.

    How many of those Saturn V rockets landed themselves back on the launch pad? NASAs milestones were not the same as, nor anywhere near as hard as, SpaceX’s. Your incompetence line shows you’re not capable of being impartial in this so there’s no real point continuing. You’re saying the guy responsible for the EV market we have no, the almost fully self driving cars we have now, the satellite internet network we have now, and the reusable spaceship booster rockets we have now is “incompetent”. You’re not here to actually have a discussion.

    Tech execs when the shortage hits: I just had a brilliant idea! Let's just give untrained junior vibe-coding engineers the power of senior engineers, and even more AI tools. Problem solved forever, bonus please!

    I applaud this, but I still say it's not far enough. Adjusted, the amount might match, but 121.000 is still easier to cough up for a billionaire than 50 is for a single mother of two who can barely make ends meet
