[Cob] rocket stove

[Amanda Peck]

IANTO SAYS that there are some of them that have worked for 9 years. But 
those would have been the early prototypes.  We haven't been able to send 
them back in a time machine to the sixties so we could see now how they've 
held up.

Ken Kern designed masonry clad barrel stoves back before rocket stoves.  
Anybody know how well they've stood up?  I'm too lazy to fish out the book 
right now, but I think his prototype was well over a decade old when he 
wrote (Charmaine, can you put that back into your catalog?).

Lisa joins the rest of us in wondering:

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.
