    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.

    Oh man, I'm a bit late to the party here. He really believes the far-right Trump propaganda, and doesn't understand what diversity programs do. It's not a war between white men an all the other groups of people... It's just that is has proven to be difficult to for example write a menstrual tracker with a 99.9% male developer base. It's just super difficult to them to judge how that's going to be used in real-world scenarios and what some specific challenges and nice features are. That's why you listen to minority opinions, to deliver a product that caters to all people. And these minority opinions are notoriously difficult to attract. That's why we do programs for that. They are task-forces to address things aside from what's mainstream and popular. It'll also benefit straight white men. Liteally everyone because it makes Linux into a product that does more than just whatever is popular as of today. Same thing applies to putting effort into screen readers and disabled people and whatever other minorities need. If he just wants what is majority, I'd recommend installing Windows to him. Because that's where we're headed with this. That's the popular choice, at least on the desktop. That's what you're supposed to use if you dislike niche. Also his hubris... Says Debian should be free from politics. And the very next sentence he talks his politics and wants to shove his Trump anti-DEI politics into Debian.... Yeah, sure dude.

    As someone else mentioned: Helion Energy: Located in Everett, Helion is developing a magneto-inertial fusion technology and has announced plans for the world's first fusion power plant in Washington State. They have also secured a significant investment and a power purchase agreement with Microsoft for electricity from their fusion plant. Zap Energy: Also based in Everett, Zap Energy is focusing on developing affordable, compact, and scalable fusion energy technology. They are working towards a commercially viable fusion energy solution and have received visits from state leaders to witness their progress. Avalanche Energy: Avalanche is planning a facility in Eastern Washington for commercial-scale testing of radioactive fusion technologies, according to GeekWire.

    Did you, by any chance, ever wonder, why people deal with hunger instead of just eating cake?

    I didn't care much about arc because it was chromium, but damn this is just bland and uninteresting compared to it

    It was very boring.
