Previously called the Appropriate Technology Course, the new jamboree format will have ten 'tracks' happening simultaneously with more than a dozen instructors. Participants can join in or watch as they please. If there's something in particular you want hands-on experience of, please say something early on. Four work-trade spots are currently available, plus $500 each for two videographers.
Alan Booker, who is teaching this year's PDC, will be creating a Sepp Holzer style spring terrace. Josiah will be leading the Fresnel Lens Glass Melter (FLeGM), the roundwood sauna and the wofatigreenhouse tracks. Jen will be leading the window quilts track and helping with the greenhouse and Abe Coley's junkpole fence track, complete with demonstration of fence-building machine. The glass melter design is currently under wraps. Other instructors will influence the development during the jamboree.
Some time is spent discussing the wofatigreenhouse which aims to provide a greywater system that works all winter. The technology is based on Oehler's ideas using mass and a cold-sink, but updated to include a deeper thermal well and a system to move air based on John Hait's ideas. Even a half ass failure will give a basis for optimization. Current plans for the roundwood, timber framed, rocket powered, skiddable sauna include an 8" rocket system which throws off all heat immediately into the small space. The wooden structure will be built the first week of the jamboree and the rocket bits and benches during the second.

Hey Paul, Quick suggestion. For your destratifying copper tube what if you put a car radiator that you spray painted black? It already has a huge surface area, depending on the model they already have a high and low temp side that it should naturally flow through and you can probably pick one up cheap at a pick and pull scrapyard. Biggest disadvantage I can think of is you may want to run quite a bit of water through to flush any residual coolant fluid.
