  •  Methane burns off into CO2 and H2O mainly (1+ / 0-)

    For every Methane burned you get one CO2 and 4 H20 Vapor.

    It is a lot better than gasoline which combusts to 8 CO2 and 9 H2O.

    •  "Per methane" what? Molecule? Pound? (0+ / 0-)

      I just want to clarify this concept, if I may.

      You can't just estimate CO2 production based on the molecular stoichiometry the way you did because different fuels have different energy values.  Rather, the way to do it is by measuring the lbs CO2 created per BTU generated during combustion.  The approximate numbers for that are:

      Coal: 210
      Diesel: 160
      Gasoline: 150
      Natural Gas: 117

      So N.G. does produce significantly less than gasoline, but it's not as extreme as you suggest with your numbers.

      Gentlemen, you can't fight in here! This is the War Room!
