Exterminate All the Brutes on HBO: An astonishing and damning docuseries - Vox
- - - Updated - - -
Even putting aside the ways it blows up historical narratives, it’s just astounding that this series exists. Documentary series have thrived in the streaming age, with a seemingly endless cavalcade of stories about true crime or bizarre cults. You could argue that Exterminate All the Brutes both fits and transcends those categories. It rigorously unspools centuries of crimes committed against vast swaths of humanity. And those crimes were the direct result of a kind of cult, one that centered some idea of a perfect human — white, male, cisgender, able-bodied — as the apex of our species. The powerful vehemently drew lines between who’s “in” (the “civilized”) and who’s out (the “brutes”), and made sure the social order was vigorously maintained at all costs.

I watched the video all the way through. Since you took the time to make such an interesting video, I'm going to take the time to offer some constructive criticism. 1. Phosphoric acid is non-volatile, and is somewhat hygroscopic. It will not dry out under normal conditions. Something else is happening in the cell to give this appearance.2. Phosphoric acid directly attacks aluminum, and will also dissolve copper if it's made anodic. It will do the same thing to stainless steel, and pretty much any metal other than platinum and some other expensive noble metals. Carbon, whether it is glassy, graphite, graphene, etc, is a less-expensive material that will work as an anode in this electrolyte system. The problem is that the bulk conductivity of graphene electrodes is low, so a metallic collector plate needs to be used, like you are already using. The catch is, that the electrolyte cannot touch the aluminum collector plates, not even a little bit. You have the right idea by mixing graphite with polyurethane, but you probably need multiple (electrically conductive) coats to make sure that all metal parts are completely protected from the electrolyte. Personally, I use wax that has been mixed with a 50/50 mix of graphite flake and nano-powder. This adds bulk and surface conductivity to the wax, while the wax remains hydrophobic and protects the metal collectors.3. Mixing PVA with the phosphoric acid will give a less conductive, but more mechanically stable dry-film electrolyte. This avoids the hassle of trying to seal a wet cell.4. Oxygen will oxidize graphene at the anode, causing it to lose surface area and conductivity. Even aqueous low voltage cells need to be sealed to keep air away from them. You have the right idea, but sealing would be even easier if you use a dry-film electrolyte.5. With your current cell chemistry, it will rapidly lose capacity if it is maintained over 0.6V. There are ways to get a higher voltage, such as using asymmetrically-sized electrodes, but 0.60V to 0.65V is a standard practical limit for graphene electrodes with a phosphoric acid electrolyte.6. 100 cycles isn't much for a supercapacitor. However, once a test is run out to 1,000 cycles, it's generally possible to see how the cell quality is trending. One little secret among energy researchers is that cycle life isn't necessarily the best test of a supercapacitor. A more strenuous and useful test is to maintain full voltage across the cell, and see how the capacitance drops vs. time. If it maintains its capacity at rated voltage for 10 years or so, it's a good cell. If it gives out after a few hours, it's very bad. Ha ha! ...or the charging voltage is too high...The cells that I've put together only work up to 0.6V. However, after they've been charged up, it takes at least a month for them to self-discharge down to 50% of their initial energy. That's pretty much up to the level of commercial supercapacitors.
