    lol yeah it's great for keeping the keg really cold... but if you lay any skin on it you'll need more than burn gel. at minus 109 it is unforgiving. us old dudes remember grabbing a metal ice tray out of the freezer and having to run water on it to get our fingers loose. but dry ice in the tank degrades to pure co2 gas instead of a liquid so it doesn't contaminate the fuel in the tank. it isn't very costly either at the cost of fuel and gas this day it helps.

      YEAH JBMPRODS, I used to work in the oil fields years ago with a pipe fitter. I remember he and I went to repair a D.O.T. line that had a hole in it. We were hanging by harnesses to do the repair. We had to cut out an elbow and weld in a new one. We had to pack the line with dry ice and also we had to mix up some kind of gel (i don't remember what it was). I remember being scared $%%#less hoping it wouldn't blow. LOL. But I know both the gel and dry ice would vaporize and the line would be open again after awhile... They shut the pipe down but with miles and miles of line it would be impossible to purge.

        I would like to say thanks to everyone that has added to this post.

        I missed chemistry class all together.
        I must admit I am one that thought carbon monoxide is what came out the exhaust. But it makes sense about the car having to be indoors for it to be high levels of carbon monoxide.

        I guess I missed alot growing up. I never knew that the dry ice would turn to co2 gas causing no contamination.

              Yep, Tom, that's what "dry ice" is. Solidified CO2, approx -100F. It transitions (sublimates) from a solid to a gas, bypassing the "liquid" stage. Unlike frozen water (ice) turns to liquid (water), ultimately evaporating (gas). To keep CO2 in a liquid state, it must be kept under pressure. In welding (or the food industry), the liquid turns to a gas as it expands when the pressure is released (opening the bottle valve).
