I would really like to tour a rocket mass heater that is currently heating a house. So if you live in Central Indiana drop a note here, actually if you live between Columbia Missouri and Indianapolis drop a note, I go to Columbia several times a year and could probably make a detour.
I'm super excited about building one, but want to get a first hand look at one before I rip up my carpet and cut a hole in my wall!
You can't have everything. Where would you put it?
