  1. I don't get to get to this forum very often any more. Here are the results of a test I did using one specific alcohol stove with various types of alcohol: Note that denatured alcohol from the paint store and Everclear returned the best results. Trangia Westwind Alcohol Stove Evaluation. Short version: IMNTBHO - This is a VERY GOOD BOB burner/stove. Using either Ever Clear grain alcohol or Denatured Alcohol from a paint store, it raised a quart of water from 69 degrees F to a rolling boil in 15 minutes. Packs light, small, and if using Ever Clear - you can drink the fuel. Long Version: Evaluation consists of Trangia alcohol burner and Westwind "stove". Trangia burner is about 3 inches in diameter and is about 3 inches tall. The "stove" is three flat shaped pieces of thin aluminum that hooks together to form a triangle that has a place to put the burner and put a pot on top of. Evaluated http://hitthetrailnewnanga.stores.yahoo.net/westwind.html May be a better "stove" - uses the same burner http://hitthetrailnewnanga.stores.yahoo.net/minitrangia.html Military surplus contains Trangia burner with Swedish military messkit http://www.omahas.com/catalog/product_info.php?products_id=363 Testing conditions: 1 1/2 quart covered pot, slightly wider than tall - at room temperature. 1 quart of water - temperature measured after sitting in the pot for 5 minutes. Pot was covered during heating tests except for 30 seconds every 5 minutes for temperature check. 3 oz of alcohol in trangia burner positioned in Westwind stove. Time check - to fully vaporized flame and then Every 5 minutes until 30 minutes or rolling boil Tested fuel 70 % Isopropyl Alcohol - purchased at a local Walgreens 70 % Ethyl Alcohol (ETOH) - purchased at a local Walgreens Denatured Alcohol - purchased at a local Paint store 190 proof Ever Clear - purchased at a local liquor store Test Results Time to heat stove before a fully vaporized flame appeared varied from 10+ minutes with the isopropyl alcohol to 8 minutes with the ETOH to less than a minute with either one of the other two. Isopropyl Alcohol - 30 minutes - 69 degrees to 197 degrees. Significantly noticeable fume smell ETOH - 30 minutes - 70 degrees to rolling boil. 25 minutes to 197 degrees. Significantly noticeable fume smell Denatured Alcohol - Ever Clear - identical results. No real noticeable fume smell 5 minutes from 70 degrees to 100 degrees. 10 minutes went from 100 degrees to 150 degrees 15 minutes rolling boil. The Westwind triangle is not a good wind break. To effectively heat/cook with the burner, you'll need to provide a wind break or a lot of heat will blow away. Why do I think it should be in the BOB? 1. In wet or cold or wet/cold weather the ability to have a warm to hot cup of water/tea/soup/whatever could be the difference between just being miserable and dead. Plus the occasional hot drink/food is a significant moral booster. 2. It packs small and light. 3. Most any alcohol will work in it - including whiskey/vodka/rum. It takes longer to get a fully vaporized flame but as it's getting going, you can too with the same alcohol. One "advangtage" the Everclear has over any of the rest - if it leaks onto your food, it does not poison the food.
