Edit: I found it(my original link)! Over at No Nanny State. Here's some additional info he posted.
My last thing to do is to make up 2 more Penny Stoves to give each bag a means for cooking food and sterilizing water. These things are amazingly light and efficient. I have found that the yellow bottles of Heet fuel line anti-freeze to be the best fuel and container. Heet is denatured alcohol, which is actually cheaper when purchased in bulk, but more difficult to carry. I just throw a couple of the Heet bottles in the bag, and that will provide fuel for at least a week.One thing I really like about him; He's in the banking industry and saw all the financial trouble coming down the pike nearly 18 months ago. He does a great job explaining they 'physics' of finance in a way that's easy to understand. I've been going through all of his back posts since yesterday - it got interesting around the beginning of 2008 (because I have a bad memory not because his old posts were bad).
There are a bunch of great links at the bottom of the Penny Stove page like:
instructions on how to make your own penny stove
where you can buy premade ones
making your own fuel
and more!! Check it out!
