Has anyone ever done this/seen it done? We love rocket mass stoves, and would like to put one in the 20 ft pacific yurt we are about to buy from a friend. This yurt is going to be our home while we build up the rest of our homestead (we bought 40 vacant acres last fall), so we need to keep things temporary/portable.
Our ideas right now are along the lines of benches filled with sand to run the exhaust pipe through.......
There is one with pictures in the alternate energy forum. However it may be more permanent than you wish as they made a permanent floor for theirs. There is also a thread about building a portable RMH. Either one may help. Also check out the pocket rocket (which is non-mass, but quick and easy).
From what I have heard sand tends to be more of an insulator than you want.
