Here's a link to the construction article. Also, I've included a URL link at the end of this article and some text attached below from a letter in a follow-up edition of ASME magazine. The original article was referred to in the August issue of ASME magazine.
I haven't built this CatStove, and when I do build one, I'm going to make mine much larger so that I can cook with a larger pot. I think you should consider his construction article more of a way to generate ideas and not necessarily a step-by-step procedure. Besides being too small, I'd like to invent a better way to control the flame setting.
This stove is intended for camping, but I'm thinking a larger one might be a nice conversation starter for the summer, backyard cookouts.
Here's the attached letter from the current issue of ASME magazine.
Brian used a CatStove on his trek. (Yes, so named because it is made from two cat food cans.) I designed this stove in 1998 for use by long distance hikers, who can be a bit phobic about their pack weight.
No cats were fed in the making of this stove: Using only a church key opener as a tool, an ME editor fashioned a light, functional alcohol burner from Robinson's instructions.
The CatStove is a regenerative heater, and operates on the same principle as the furnace in your home. It was my attempt to improve on the familiar Sterno can stove, which was everything a good stove should not be. The oxygen needed for combustion is trying to get into the burner the same way the flame is trying to get out. The result is a stove that will boil a pint of water in about 15 minutes under good conditions.
By adding an air jacket and making some other improvements, I was able to control the flow of air into the burning chamber. The incoming air also captured any heat lost through the sides of the burner (regenerative heater). It will boil a pint of water in four to five minutes, using just two tablespoons of alcohol fuel. No moving parts, nothing to clog or get lost. Instructions for making one are at

Here's a picture of the CatStove in operation. Not sure this link is going to work, however. I've not tried posting images yet. I see it may not be working. If you want to see the picture, guess you'll have to click on the link.
