I mucked about with can-based methanol burners for a while, and found that a vienna suasage can with holes punched around the rim worked as well as any. Dog liked the sausages, too. Thing is, using this requires a paradigm-shift, wherein one uses the extended heating time to enjoy how quiet the burner is as it slowly, slowly, slowly heats your water. Enjoy a glass of wine, reflect on the harm that petroleum products do to the environment, celebrate the fact that your alcohol burner can operate on on organically produced fuel. Very french in outlook.

Add it to the list of things that make life seem to last longer.
