As so many people are poisoned by CO each year, the interpretation might be good for the stove business or product adoption, but people will probably think they can use the device indoors with closed windows.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>There is also some confusion about the word ‘carbon’.

This of course refers both to the CO but also to the oft-repeated meme the carbon dioxide is a ‘pollutant’ and therefore must be ‘poisonous’. Oh well… Obviously they mean carbon-monoxide which <i>is</i> poisonous, but they then indicate it doesn’t produce any.
