This discussion has been rolling for more than 15 years and includes everything from shop tinkering to substantial field experience. </span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D"> </span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">Have you been in contact with Peter Scott at Burn Design Lab on Vashon? <a href="http://www.burndesignlab.org/">http://www.burndesignlab.org/</a> They are about 10 minutes north of you just off the Vashon highway. Peter can show you what our challenges are and how we approach them. We don’t have densified fuels like bricks or fire logs to work with. We have miscellaneous and low quality fuels including everything from corncobs to coal. (I have burned Washington coal.) We have to deal with the smoke and gases all during the “once you get up to temperature” time. So you may have found good performance at a peak temperature but stove emissions and efficiency performance has to follow the whole cooking experience from the time you light the fire. We are concerned with fuel efficiency but also with health effects of particulates and gases. There are several gigbytes of information on the website that we maintain to complement this discussion <a href="http://www.stoves.bioenergylists.org/">http://www.stoves.bioenergylists.org/</a> </span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D"> </span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">Puget Sound has been a rich source of ideas and development for improved cooking stoves, solar cookers and retained heat cookers. Each year in January about 150 of us from around the world gather at Northwest University in Kirkland, WA, for the ETHOS conference. You will find much information in the conference proceedings. <a href="http://www.vrac.iastate.edu/ethos/proceedings.php">http://www.vrac.iastate.edu/ethos/proceedings.php</a> Art Donnelly’s Seachar.org project is in Seattle, developing biochar making stoves for developing countries. Organizations in Mount Vernon have developed sophisticated pellet burning stoves for developed, and now developing, countries. Larry Dobson on Whidbey Island has developed stove concepts for many applications for more than 30 years. Masonry heaters and cookers have been developed on Lopez Island and installed in Central America. A couple of us on Shaw Island are heavily engaged in improved cooking stoves and heating devices. </span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D"> </span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">Your heating device must, of course, be certified by EPA if you intend to sell it in the US, Canada, Europe, NZ, etc. Testing methods and standards are easily found and there are certified labs in the region that to do that work. New ASTM and EPA wood fired boiler standards also apply.
