    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.

    I'm willing to bet it's option B. Bet someone in management decided it would be best to cheap the fuck out now and then beg forgiveness later, and sell it as increasing security, than ask permission from the beginning.

    The thing about compelling lies is not that they are new, just that they are easier to expand. The most common effect of compelling lies is their ability to get well-intentioned people to support malign causes and give their money to fraudsters. So, expect that to expand, kind of like it already has been. The big question for me is what the response will be. Will we make lying illegal? Will we become a world of ever more paranoid isolationists, returning to clans, families, households, as the largest social group you can trust? Will most people even have the intelligence to see what is happenning and respond? Or will most people be turned into info-puppets, controlled into behaviours by manipulation of their information diet to an unprecedented degree? I don't know.
