So using steam to induct air shortens the chimney, stirs the fire and probably improves the combustion efficient all at the same time, with the only loss being the latent heat. Because the combustion wasn't all that great to begin with, there could easily have been a net gain in fuel efficiency. <o:p></o:p></span></p></div><div><p class=MsoNormal style='background:white'><span lang=EN-US style='font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p></div><div><p class=MsoNormal style='background:white'><span lang=EN-US style='font-family:"Calibri","sans-serif";color:#1F497D'>As the volume involved is so small, couldn't this also be dome using ethanol or methanol as a 'propellant'?
