I had afew hours to kill this mourning. This is a very worthwhile project to put together. It produces quite a bit of heat with comparably low fuel demand. Quite impressive actually. Mine produced more smoke, I didn't seal it up because the only thing I had around here was pea gravel. I'll replace the pea gravel w/ cobb or vermiculite, seal it up and it should be good to go.

I have one in the beginning stages being made out of a 20lb propane bottle. I also plan on making a heater attachment to stand on top of it to capture more heat before it vents out of a shelter or what have you.

A propane tank would be a good size to use. Big enough to produce alot of heat but portable enough to move around. Could you circulate water though it w/ copper pipe?
I found it interesting that even after the fire burned for over an hour in the coffee can stove, I could still pick it up without burning my hands.

For your practice one, you can just use dirt, just mix it with some water and pack the mud in there. If you have a fireplace or wood stove just use ashes.
