CO2 is a very cheap gas. You would need a great deal of it to be worth messing with. If you have a greenhouse you could vent it in there when the sun is up.

The concept that I had and didnt fully explain was to use the large propane tank as a vacuum reservoir to draw the vapors into the tank to be drained from the bottom after they condensed. This would isolate the air compressor from the ethanol vapor. This would also (I believe) draw off and contain the CO2 for further processing at a later time. (Is there a ready market for CO2?) But it would need a large volume of ready vacuum at the beginning and continuously thro the process to keep the air compressor isolated and the various vapors contained. I am making the assumption that a pressure container will hold up to strong vacuum stresses. All pressure containers are required to undergo a inspection on a set schedule. The tanks that are not suited for re-certification for propane are sold as scrap metal and recycled. ------------------------ Yahoo!
