Two Letters Re: Small Campstove Cooking

Sir,
I read R.E.’s article on Small Campstove Cooking with interest. Thank you. I’ve tried a few as well varieties of stoves as well and to date my favorite is the Littlbug. It’s sturdy, stainless steel, comes in two sizes, folds up, it has some adjustments, and can burn solid fuels or twigs very efficiently. Twigs removing the need to carry fuel. Blessings, – Steve B.

Jim,  
Just a quick note about a comment R.E. made in his article: “Whether a stove unsafe for a small tent would be safe in a home is uncertain. Just remember that carbon monoxide (CO) is lighter than air.”  Carbon monoxide is only very slightly less dense than air (1.145 g/l^-1 for CO versus 1.184g/l^-1 for air – a smaller difference than there is between oxygen and nitrogen).  It is not light enough that you can expect it to rise to and collect at the ceiling or in upper levels of a structure and in a home CO will mix homogeneously with air.  My intention isn’t to ding R.E. but to make sure that folks don’t get the idea that sleeping on the floor would make them safer while using an inefficient heater or other CO source.   – Matt R.
