I attended this workshop in February 2009. The primary instructor was Ianto Evans, author of "Rocket Mass Heaters: Superefficient Woodstoves YOU Can Build" other instructors included Ernie, Erica, Max and Kiko. Basically, this is a super efficient wood burning stove, with a cob bench bench thermal mass to hold the heat. One tiny fire can heat a room (and warm your butt) for a day! Please forgive that my camera is not the best, but I think I got the main information across. Lots of discussion about this sort of thing on the forums at http://www.permies.com
