Visualizing Toxic Air
It's time we moved towards a world of "you may not vent anything to the atmosphere".<p>Ie. nothing may have a chimney, exhaust pipe, pressure release valve, or anything similar.<p>All gases must be stored in a tank and reprocessed at gas recycling facilities, which can separate out and sell the gases.<p>Even in your house, when you 'ventilate' the house, you are taking the stinky stuffy polluted indoor air and putting it into the environment.  The volatile organics, farts, Nox from your cooker, CO2 from breath, and cooking smells aren't 'natural'.   Instead, your house should purify its own gases with filters.<p>Will it be expensive?   Yes.    But looking after the environment is expensive.  But it's worth it.
