I've built 10 or so PepsiG stoves in the past 3 weeks, and have a four day outing this weekend in Mark Twain Nat'l Forest in Missouri. Plan on putting them to the test, along with my new Becker CU-7 and the fish bags generously donated by dchinel .

My best stove can boil 2 cups of water (rolling boil that is) with 2 Tbsp of fuel in about 7 minutes. This is with normal tap water temperature, in the garage (around 50 degrees) and without windscreen. I'll have to see how it does in the wild under less optimal conditions. At least I'm shaving around 2.5 pounds off my pack weight on this trip by using a stove with no parts to wear out, and weighs just grams.
