The first experiment was hampered by them not realising the cement needed CO2 to cure, to be honest I would have halted the experiment to find out what the issue was then restarted it. Although they might not have realised this at the time, but then they weren't really testing a proper closed system.
It would have been useful if they were able to test a closed system without the cement sucking up the CO2.
- tgb 7y agoIsn't cement a major CO2 emitter?
- ch4s3 7y agoThe production of cement is, but curing cement fixes CO2. It just doesn't fix enough to offset the production.
- PorterDuff 7y agoOn the restarting, I completely agree. You'd need to restart the whole thing multiple times as your knowledge increased. Maybe somebody else is doing large scale closed system human habitats, but I haven't heard of any. edit: A bit of googling led me to the Russian one and some books on the problem generally. It sounds like a great speciality but probably hard to get a gig in. If I had a multi-decade old terrarium, I'd be darn tempted to think of sensors you could stick in there and see if there's some sort of cycle going on.
