I think if the RMS heater was treated as a masonry heater with a separate core and facing... the core is the part that needs the most engineering, so if a standard core could be designed that can be standards approved (CSA in Canada, UL or EPA in the US) then the facing could be much easier to deal with... it would still have to be fireproof... but cob should be possible.
I completely agree with you that stacking and fuelling have enormous impact on emissions. However, I have come to realize that it is extremely difficult to teach the operator here, in North America - I find that quite a few of my customers don't even read the manual I supply them with... From now on I am giving my clients a Client Acknowledgement Form to sign. They are signing that they have received the manual and instructions and understand importance of following them. I hope it will help somewhat, but I am afraid not that much.
I have come from a country with strong traditions in masonry heaters, country where people are used to follow certain firing routine and perceive it as the norm. And I used to think the same way. However, it is very different here. Too many people apply open fireplace firing techniques to masonry heaters either conscientiously or not simply because there is no tradition for masonry heaters. It takes centuries and generations to develop right attitude towards wood fire and firing own heating fireplace. It is very difficult to change.
Is it OK if my stove pipe runs "uphill" slightly? Or will the "water" that is supposed to exit at the end (along with the CO2) run backwards downhill back toward the stove? Getting ready to put this in my new greenhouse and the floor isn't level.
If water barrels sit very "near" the stove pipe will the water in the steel drum get heated by being only an inch from the pipe, or does it have to be encased in mortar or cob?
I was wondering if anyone had any ideals for powering a fan - not using electricity?
I was also thinking of a weight being pulled down by gravity - i'd love to hear of any ideas involving a short action that results in two the there minutes of "fanning".
I was thinking of using a long-ish lever or bar to compress a spring of some sort. That would then relax over a period of two or three minutes - and provide the energy to spin something creating the breeze. The breeze would be especially iseful when startig the stove to help get the draft going, or periodically stoke up the fire is using less than ideal wood, etc.

if I remember correctly you stated that a rocket mass stove heater you had built substituted pebbles inside of a plywood box for the mass, instead of cob.
If I've got this right, would you happen to have any pictures or plans for such. I've searche many of the YouTube videos and did not see this. Thanks.
I'm curious what other rocket mass heater folks think of this: www.greenoptimistic.com/2008/11/06/candle-room-heater
Around here everything is very steep, so most folks have to build houses with very small individual floors a few floors tall. often each level has access to the ground. I am wondering what the collective wisdom thinks about having a traditional stove on the first (bottom) level with a flue which traveled straight up to a heat riser/reburn barrel on the second floor.
I would like the ducting clarified by someone. Is the combustion chamber ductwork the same as the heating ductwork in the RMH?
I love the concept, and thank you for the videos etc as to how to build this!! I am considering this, and also wrapping the ducting with copper hose to heat water that would be circulated through radiant flooring, the hot water heater, and out to the greenhouse via solar / photovoltaic driven pumps to maximize the heat capture... Any thoughts, or experiences from those who've done it?
The fourth picture at this site has a bench, and it it lined with wood. I was wondering if people thought this type of bench would work for a rocket mass heater. It looks nice to me, but would the wood be a problem? http://www.fotevikensmuseum.se/engelsk/art_english/e_art17bq.htm.
