On the same note: Down hill exhaust sounds good... if it can be controlled. I would think an exhaust that goes down hill to a gravel pit (to collect the water) and only releases CO2 to the plants around it would be a good idea. The weight of the cool gas could suck flue gas through the system. (the gas is not only cooling and shrinking, but changing composition as well, the water would be condensing and so the flue would have to drain properly too) The mass to achieve this would have to be large and may need to conduct heat better than just earth (water maybe?) And of course the site would have to work with it, having CO2 pool could be hazardous.
You had your fun. Now it's time to go to jail. Thanks for your help tiny ad.
