Jim, when you say efficient, you are referring to some measure of liters of water boiled per ounces of alcohol consumed, right? Do you have figures on how efficient the Trangia is compared to some of the others?

It boils down to the ultimate question - how many days use will it take the more efficient Trangia to overcome its burdensome (3 oz!) weight? Enquiring minds want to know....

How is it possible that no one has as yet favored us with a Titanium Trangia (Tirangia?)?
