    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.

    You said it yourself: extra places that need human attention ... those need ... humans, right? It's easy to say "let AI find the mistakes". But that tells us nothing at all. There's no substance. It's just a sales pitch for snake oil. In reality, there are various ways one can leverage technology to identify various errors, but that only happens through the focused actions of people who actually understand the details of what's happening. And think about it here. We already have computer systems that monitor patients' real-time data when they're hospitalized. We already have systems that check for allergies in prescribed medication. We already have systems for all kinds of safety mechanisms. We're already using safety tech in hospitals, so what can be inferred from a vague headline about AI doing something that's ... checks notes ... already being done? ... Yeah, the safe money is that it's just a scam.

    I have been chuckling like a dork at this particular patent since such things first became searchable online, and have never found any evidence of it being manufactured and marketed at all. The "non-adhesive adherence" is illustrated in the diagrams on the patent which you can see at the link. The inventor proposes "a facing of fluffy fibrous material" to provide the filtration and the adherence; basically this thing is the softer side of a velcro strip, bent in half with the fluff facing outward so it sticks to the inside of your buttcrack to hold itself in place in front of your anus and filter your farts through it.

    Looks like the delay in 2011 was so big the data became available after the 2017 one

    Cool. Well, the feedback until now was rather lukewarm. But that's fine, I'm now going more in a P2P-direction. It would be cool to have a way for everybody to participate in the training of big AI models in case HuggingFace enshittifies

    Ah, I see what you’re saying, I misunderstood and thought you were taking about picking a different book. Indeed, for the worst case scenario a mediocre AI voice could be an improvement!
