One of the more amusing stories to come out of NASA’s fun fakery labs. Is there a youtube of an exploding poop rocket? That would be messy.
However, instead of designing special rockets to burn the waste, human waste can be converted into methane, resulting in enough power for rockets to bring astronauts home from exploring the moon or even more distant targets.
“The moon base would process the fecal matter into methane, a flammable gas that can be used to produce fuel for modern rockets. New techniques will see 290 liters of the gas per crew every day produced over the course of a week.”
