Wow...fascinating. What is the psi when full and cf? Diving was my profession and the cylinder looks like a 50cf @ 3,000 psi dive tank. And CO2 is an escape artist!
I looked up the periodic table, damn it looked strange after all these years, and found C next to N and they both have associated O...but I did find out that the molecular structure of CO2 is linear and thus "sharp" [I know not very astute] while air of course is a combination of many gases beside N and O so does not have a molecular shape.
For me with restricted space, I will go with a small version of a good compressor...besides I have no idea what the volume of my 265/75 16 tires are at the normal 40 psi. Assuming the worst and a flat I might need a lot of volume. Besides I lugged around thousands of dive tanks over many decades and toting Hp cylinders anymore does not catch my interest..
Great food for thought and thanks.
Sorry to digress from the tread topic but Bishop and that side of the Sierra Nevada Mts. ["the right side"] is a favorite spot on the planet for me. I grew up in Reno in 50s when there was nothing but sagebrush and clean air!
Lastly, the Steen..Alvord..Trouts and Owyhee areas are truly off road heaven...pity those that have never been there..
Now if you drop down into the Rubys .....
Take Care,
