I can tell you are all rocket stove pros! I know very little but what I have seen online - youtube etc. I am wanting to build a stove for emergency purposes -- to cook for my family. I was thinking about using the large oil can - as versions made with #10 cans just don't seem like they would get hot enough -- but maybe they do! I understand, after reading through your forum that some materials burn out after short time.
So my question is: Is there a basic, no frills plan out there?
What materials would you recommend using for the outer drum and the feeder tube and heat tube ? (see - I don't even know what to call them!).
What insulation would be sufficient?
I have seen so many different things out there -- now I'm just confused where to start!
Thanks so much for considering my question.

shjared,
For a cookstove I would think a 5 gallon pail with a stove pipe elbow running through it filled with perlite or vermiculite(some use wood ash, but it tends to pack over time)would be more than enough for an emergency.

I think the pail and stove pipe ideas are good, but I would suggest a "T" rather than an elbow. The elbow will tend to have an issue with coal build up. The "T" reduces this problem by giving the coals a place to collect, which also helps with a cleaner burn since they provide some good concentrated heat right at the bottom of the riser and below the fuel.
As for the vermiculite/perlite, I'd suggest you mix that well with clay soil or clay slip as the stove pipe will burn out and any loose insulation will flood into the burn area. I've had success with a mix of clay:ash in a 1:2 ratio. Makes a light weight "brick-like" material once it is fired.
Finally, I've had good success using a 4" horizontal feeder tube connected to a 6" heat riser. The larger riser seems to contribute to a cleaner burn. I've used 6" institutional food cans.

hpmer, True that is a longer lasting, more efficient design.
I thought she wanted something quick for emergencies.

Good point. But the last thing you want in an emergency is to have to repair the stove when you could know in advance what the problem would be. The stove pipe only works for so long, so I guess it depends on how long your emergency lasts. I think it better to spend the time and effort now when one can do so at their convenience. But your point is well taken.
