After hearing some people complain that their Supercat stoves run out of fuel before they reach a boil, I started searching around for a can that would have a higher capacity. I think this one does the trick:

I doubles the capacity of the Supercat from 1 oz. to 2 oz. and is a little wider to increase stability.

Hi Jason:

Thanks for posting your design. I made one of these larger stoves last night, and hope to try it soon. It answers one of my only complaints with these little stoves- that they run out of fuel too quickly to boil the water in a larger pot.

Thanks again,

Thanks. I still think I need to play around with the hole pattern becasue it's not very effecient. I'll post any updates. Let us know what your experiences are.
