I think the fire would probably die, I suspect it's for getting oxygen into the can, as the big opening would be closed by a pan/pot that's standing on the stove. Does that make sense?

I don't think the hole is for oxygen. Alcohol vapours burn outside the stove not insade. I think it is there to prevent buildup of pressure wich would force the alcohol out of the ''fuel dents''. That way you avoid having a fire breathing monstrosity on your hands.
I have often wondered about a makeswift stove. Might be a life saver some day. I'm a little concerned with fuel efficiency though.
I've not made one of these yet, looks easier than drilling lots of little holes And I've not set myself alight for ages
Very cool Gareth. Glad to see it worked out well. I still need to test mine. What did you use for fuel?

OK, it works. Pics to follow in a minute.
Its your fault I have just HAD to buy 4 cans (well I may need spares) of JD and coke:-) Sent from my Hudl HT7S3 using Tapatalk
...I wonder if it will work with Primus burner fuel? ...

The trouble with alcohol based fuels is they provide low thermal output, so one has to carry a lot of fuel or rely on these stoves only in an emergency.
Now I have to give Can Stoves a try, I used a Trangia knock-off until now.Quote from: firiki on December 12, 2013, 11:45:04 AMThe trouble with alcohol based fuels is they provide low thermal output, so one has to carry a lot of fuel or rely on these stoves only in an emergency.If you want something for an emergency, I would say go with the Schweizer Notkocher 71 (http://survival-mediawiki.de/dewiki/index.php/Schweizer_Notkocher - The text is in German, but the pictures show the design pretty well). It uses Ethanol Jelly, can be put out using the cap, can be refilled after use and comes with a stove-top. It's more reliable and durable, but certainly much more heavy.
It reminds me of some tray heaters we were using when I was working at a catering company.
