>and 1.8 kilos of dried food a day to stay alive. Isn't that a lot? A stick of bread is 0.25kg, burger patties no more than 0.2kg, and so on.
On water reclamation: > On the Mir space station, this used to happen organically. Collecting water was a grubby job that involved chasing beach-ball sized spheres of condensate around the colder parts of the spacecraft with trash bags before they could climb into the walls and cause mayhem. Crew members spent three to four hours a day on this dirty and difficult task. That sounds, frankly, horrible. It made me think…
Curious that both average inputs and outputs match to exactly 5.74 kg. I had intuitively assumed there would be a significant difference, but I suppose that even if a lot of energy is extracted, the mass difference will be negligible, mc2 and all. I'm also surprised that the vast majority of the output carbon is in the form of CO2 rather than feces. It's all rather obvious in retrospect, it was just nice to see cryst…
> I'm also surprised that the vast majority of the output carbon is in the form of CO2 rather than feces. Not sure if you know, but in the same vein, I was shocked when I learned ~50% of the biomass of trees is carbon (right, we knew that), but also that the carbon came from CO2 the tree respirated. Also makes total sense in hindsight, but still think it's so cool. The trees literally build their mass from the air an…
