It seems obvious the the heaviest part of the stove works should be over the rear axles but am concerned about total weight using clay. I realize lightening it up may well make it less efficient, but would like knowlegeable feed back on this. I am also wondering about incorporating a rocket stove type water heater into this project.
Less efficient because it's lighter, maybe, maybe not. I'd think that you could raise it off the floor via concrete blocks, (fairly light) and then just do a shorter run for exhaust before it goes out a (window or side)? I mean how much do you have to heat an RV? a 8x??32' space? A small rocket stove should do that. It also seems that clay if spread out (i.e. raised off floor) shouldn't be too heavy. I'd just wrap copper tubing (1/2inch is cheap) around the barrel when you're firing it and it should heat enough for at least 1 hot shower/small bath. If you run the mass (i.e. 2 exhaust runs suspended on blocks, covered in clay) it should be enough to sleep on and shouldn't over tax the dually axle (less than 8,--- total i would think).
You're not going crazy. You're going sane in a crazy word. Find comfort in this tiny ad:
