the stove will be a small rocket stove made from ytong bricks and the stratification chamber will be a stainless steel beer barrel.
I looked up stratification chamber after I posted
Cool like that old trick where you make smoke go downwards
you take a Cigarette Cellophane half way off the pack
roll a piece of paper off the pack
Burn whole in Cellophane with rolled up paper ,
and watch as you poke it through smoke goes down like a water fall.
I no longer smoke but still cool.
You think about getting a Heat cable or generator
just in case anything goes wrong
I know you said wouldn't use solar , but a hybrid system could be useful
running a trail with zeolite wouldn't be bad on one pipe it's cheap.
I did forget (my brother mentioned ) Soapstone for heat Transfer .
I will try to find some links I have buried.
