I still haven't solved the CO2 bedroom challenge
You open the window and you wake up from a 6am garbage truck or barking dogs and sunlight
You close it, you suffocate in 1200 ppl at 5am
I guess you really need some mini tube in your wall with a vent that opens and closed based on internal CO2 but how do I build that?
