[Cob] rocket stove

[Lisa King]

I had a question about the longevity of the rocket stove. I have  concern 
about the metal barrel burning out over time, I know my old barrel wood 
stove eventually gave out. It just doesn't seem like it would be very easy 
to replace the barrel.
I'm wondering if there are any thoughts on
    * how long it would take for a barrel to give out.
    * How one would replace it.
    * Or if there is a material that might last longer.
On the same vein, in the rocket stove book Ianto talks about the bricks and 
how no matter what type you use eventually they will break down. I wonder 
if there is any idea on how long this could take and how we would go about 
replacing or even knowing such a thing happened.

One of my concerns is things breaking inside where I can't see it and some 
type of smoke filling the house while we sleep or some type of oxygen 
stealing event like you hear on the news.

My other concern is that this might only be a viable stove for maybe less 
then ten years and if that is the case I'd like to think on that in my 
design if possible.
