Since the anaerobic digester is likely to weigh more than 2.03 kg its inclusion in the process is a net negative.


Fair enough. But since there will have to be some sort of sceptic tank
somewhere, the weight of that digester is mostly already there on the
ship. Unless the toilets vent to space.


I happened to notice that the ESA has issued an Invitation To Tender for
a project called "Biomass Propulsion Subsystem" (ESA ITT AO70236).

However, on closer reading it (sadly) turns out to be unrelated to this
thread, because what they want is an ordinary propulsion subsystem for a
satellite called BIOMASS. :-)
