They have built several, but the rest are not so directly integrated with the earthbag wall.
Thanks! That is exactly what I am looking for. I don't know how practical it would be, but I would like to make every third layer of my eb house with a hollow space in the middle and run the exhaust tube through that...to heat up the whole wall. i wonder if that would destroy the integrity of the wall?
