Googling DIY oxygen concentration and production reactions. It appears there is no simple method. Electrolysis sounds simple but is apparently not. Industrial oxygen has purity problems. Concentration processes use zeolite which isn’t generally ubiquitous.

Sheds whole new light on the idea of “spaceship earth” Something as basic as breathable air is only available free and low-tech in a very narrow band around healthy. Drop below 90% or whatever and the full might of full-stack civilizational technology is necessary.

Larger hospitals have oxygen generation capacity but most of the supply is done at centralized scale and requires cryogenic distribution. It’s not one of the resilient basic gases that can survive infrastructure failures. At least not at any meaningful scale.

I feel discouraged by the tone of the sudden diaspora focus on oxygen in India. Accepting it without normalizing a racist sense of supremacy would be difficult, and this seems so clearly a failure of the state and political will rather than a lack of technology or resources.

I remember feeling this urgency about ventilators last year, and absolutely everyone should be doing everything they could, but why is there a helplessness to it? Where is the rage? Why is the government of India not frightened by the intensity of that rage?
