Has anybody tried to exhaust a
rmh through an earth tube? I think the tipi
rmh exhaust ran through the ground to get back to the barrel before entering the chimney. It seems to me that a earth tube going downhill would allow the exhaust to fall as it releases its heat. This combined with the push from the rockety bits seems like it would work.
If this works, running it through or underneath a hugelkultur bed could jumpstart the growing season.
