>>5442146You'd already know how they work as it's pretty common knowledge, albeit the exact mechanics escape you. It's a genetically engineered organism somewhere between a fungus and an animal, spread on flat shelves or in boxes (the exact method varies). You throw in nutrient slurry (preferably a mix between fruits, grains, and vegetables, but meat is fine too), and out comes blood to fuel machines. It isn't very high quality, basically the robot equivalent of those all-in-one nutrient shakes, but it works for all but the most high-performing machines.
There are medical-grade ones capable of outputting blood of equivalent quality to humans, but those are rare and all in the prototype stage, given that they required human DNA to make. This means that there are Blood Barons controlling these few sites, guarding them jealously and doing anything to keep them producing.
