Math seems wrong "The team found that the loop design would convert 75% of the gas entering the system into useful resources, producing carbon nanotubes and hydrogen in a 3:1 mass ratio. In other words, for every 4 kilograms of methane the system successfully converts into useful resources, it makes 3 kilograms of nanotubes and 1 kilogram of hydrogen."

The 75% and the 3:1 ratio are not related. Methane has the formula CH4, so for 12 grams of carbon you have 4 grams of hydrogen. If you successfully break down the molecule CH4 you get a carbon-hydrogen ratio of 3:1. Now, let's say you start with 5.33 kg of methane. Only 75% gets converted, so that's 4 kg. Of that, you get 3 kg of carbon and 1 kg of hydrogen.

(I had to reread that paragraph a couple times too)

Are the max yield and the yield efficiency numbers mixed up?
