OK... So Natural Draft, with or without a partial stack assistance. A 3' 
stack, as from a 4" diameter clothes dryer duct, or tin cans forced 
together, will really help.

OK... for stickwood, what about a Rocket type stove? For heating, what about 
a 5 gallon paint can, or a 45 gallon drum, with a small stack as noted 
above?

A Rocket, or one of Lanny Henson's stoves should be good for pot cooking. 
Also, Dr. Reddy posted some good clay based stove designs. on teh Stoves 
list.

The above stoves should do that.

OK... do a google on "Tent Heaters" or something like that.

OK... Obviously, people don't wasnt to pay more when tehy can pay less, but 
usually, if they have a bit more money to spend, tehy can get extra helpful 
features.

OK... car parts, tin cans, scrap metal, old appliances, ? There are a lot of 
materials that cxan make excellent no-cost stove construction materials.

>> What local crafts or skills are available?

OK... what about clay stoves, like those presented by Dr. Reddy? Tincan 
stoves that can be made with a can opener, a nail, and a jacknife?

OK,,, you can start with something simple, and point out the problems and 
shortcomings. Send your WSorkshop Attendees out on a "Scavenger Hunt" to 
find materials or components that will make a better stove.

OK!! Hope this is going in the right direction.

Best wishes,
