Dear Roger and Bridget, Nice piece of work! Even a tray for the ash, most producers of stoves to day seems to "forget" that biomass produce ash. (Gasifiers produce little ash) I just recall, that you where looking for a stove in combination of heating and cooking to fit in a boat or a small cabin. Have you tried to ignite the biomass from the top? By doing so, you will burn out the gases in the biomass, first, and will have a very clean and efficient burn, despite a chimney or not. Most people seems to forget, that dry fuel (less than 10% moisture) and ignition on top of the fuel, is just as important as an "efficient" stove. Have you tried or considered pellets?
What is your retail price? I very much agree that such a stove will be very suitable for outdoor activities, as well, like in tipies and small cabins in the high mountains. Have a nice and warm day in Washington. Good luck.
