Cause i put up a post a few weeks back raving about my new butane stoves i thought I should put in this warning about butane as a fuel given the winter is soon upon us:

"Butane Lighters
If you go to the local store and buy a disposable butane lighter with a clear case (so that you can see the liquid butane inside), what you are seeing is liquid butane stored in a high-pressure container. Butane boils at 31 degrees F at normal atmospheric pressure (14.7 PSI). By keeping butane pressurized in a container, it remains liquid at room temperature. If you took a cup of butane and put it on your kitchen counter, it would boil, and the temperature of the boiling liquid would be 31 F.

The boiling point of butane, by the way, also explains why butane lighters don't work very well on cold winter days. If it is 10 degrees Fahrenheit outside, the butane is well below its boiling point, so it cannot vaporize. Keeping the lighter warm in your pocket is what allows it to work in the winter."
