Reddit mentions of Fire In Your Hand: Dave's Little Guide to Ultralight Backpacking Stoves

Take note that fuel he's using is very likely denatured alcohol, also some protips:

For a better looking stove, take some very fine grit sandpaper and sand the paint ends of the cans, while they're full. You can try to sand them when you've emptied them but trust me, full is easier.

Try using cans with wider bases to get a better heating area, think about those Foster's oilcan' beer cans. The aluminium is a little thicker on those as well, so your stove will hold up better.<br /> <br /> Additionally, by picking up some cheap wire fencing you can construct a pretty easy potstand that will keep your food and heating pot/cup off of the direct flame.<br /> <br /> The filler that the constructor is using, is likely fiberglass. Go with that, instead of regular cotton because, well.. duh, flammability. <br /> <br /> These awesome little stoves aren't just used by hoboes but also by a lot of ultralight backpackers who can sacrifice the weight of a can of propane and larger/weightier stove by constructing one of these. Source: I'm an ultralight backpacker who has constructed close to several hundred of these little guys :)<br /> <br /> **Edit:** forgot the word &quot;fuel&quot; and added clarification for &quot;Foster'soilcan' beer cans."

Edit 2: Wow, this got a lot of visibility! Cool! For those backpackers who are looking to lighten your load or for some general backpacking advice, why don't you head over to /r/backpacking and/or /r/Ultralight where there are plenty of knowledgeable folks just waiting to critique your gear list and help get your pack squared away. Also, you don't necessarily need to use denatured alcohol, but isopropyl is dangerous and leaves nasty residue in and on your cooking cup/pot. Plus, I've found that denatured is easier to find in a lot of places. You can also substitute HEET or other jellied alcohols but be warned, there are other stove designs that use that type of fuel a lot more efficiently. Trying to stuff jelly into the one that OP's demonstrating will be an exercise in futility.

Edit 3: For those of you who are looking for some more resources about constructing these things, you should experiment! Jump in and make your own, test them out, experiment!

Also, here's some web links that might help you, that I've found helpful in my journey with making these:

Zen and the art of the alcohol stove.

A drop of rain blog, fuel consumption and weight.

Adventures in stoving, DIY alcohol stove design principals.

And finally, Dave Sailer's book who was almost directly responsible for inspiring me to go ultralight and build a stove in the first place. (Ignore the one bad review, he's an extremely humorous writer and this book is a great read.)
