    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.

    So they're doing good work at least.

    The amount of effort vs a handful of toddlers, and people looking bored until they start just laughing. I’d be so embarrassed if I was one of the robots.

    Just for the record, even in Italy the winter tires are required for the season (but we can just have chains on board and we are good). Double checking and it doesn’t seem like it? Then again I don’t live in Italy. Here in Sweden you’ll face a fine of ~2000kr (roughly 200€) per tire on your vehicle that is out of spec. https://www.europe-consommateurs.eu/en/travelling-motor-vehicles/motor-vehicles/winter-tyres-in-europe.html Well, I live in Italy and they are required at least in all the northern regions and over a certain altitude in all the others from 15th November to 15th April. Then in some regions these limits are differents as you have seen. So we in Italy already have a law that consider a different situation for the same rule. Granted that you need to write a more complex law, but in the end it is nothing impossible. …and thus it is much simpler to handle these kinds of regulations at a lower level. No need for everyone everywhere to agree, people can have rules that work for them where they live, folks are happier and don’t have to struggle against a system run by bureaucrats so far away they have no idea what reality on the ground is (and they can’t, it’s impossible to account for every scenario centrally). Even on a municipal level certain regulations differ, and that’s completely ok! So it is not that difficult, just write a directive that say: "All the member states should make laws that require winter tires in every place it is deemed necessary". I don't really think that making EU more integrated is impossibile

    Oh I agree. I just think is part of the equation perhaps the thinner and lighter will enable for better processor? Not an AR guy , although I lived my oculus until FB got hold of it. Didn't use it ever again after that day.

    Worked with the US federal government for much of my professional career, mostly in an adversarial role. "reliable federal data sources" do not exist
