I found this YouTube clip about Dowling Stoves that I thought might be of interest to some. They are individually designed and made in a small fabrication shop. The designs supposedly get very complete combustion just by the layout of the firebox and air path - no fancy baffles, firebrick or secondary burn chambers. Just pure radiant heat, coming right at ya. And they are very beautiful... in a purely functional kind of way. Check out how clean the glass is. I want one!
