Do you know of design thats works just as well without a wick?

Or if they need a wick can you advise me on a good wick material.

I can't seem to find any wick that does not burn away, Lowes does not have them, the stuff I found was flat but turned to ash once the fuel was gone.

How long does a wick on the outside of the stove last?

Has anyone used steel wool inside the stove? I don't have exposed insulation in my attic
