In the next model, you will simply have a hose connected to some rubber underwear and a filter, then co2 scrubber. You eat beans for a few days prior to operation...
 
Sorry, it's mostly methane: CH4. It is lacking both CO2 for the scrubber and, more importantly, O2 for the (l-)user.

On 2nd thought that latter bit may be considered a feature.

Dunno. But you can definitely asphyxiate on methane. Besides, the GW potential of methane is 20x the GW potential of CO2. And besides, it's rather explosive if mixed with air.

No Methox then.
 
Yup.
