This is good. However, there are many variations to be found on youtube. Some of the most sophisticated are by a guy named Tetkoba who seems to have a career in alcohol stove design. Also, the standard 12 oz. drink can makes a stove that may have a wider flame area for the smaller pots used by solo tourists. A stove made from smaller cans, e.g., from V8 juice or the smaller Red Bull energy drink cans may be more suitable for smaller pots and use the fuel more efficiently. I wish that it was just as easy to make a stove using gasoline as it is universally available and costs 3+ times less than alcohol but I know that it will never be possible.
