I think that a Kelly Kettle makes a near perfect tool for just about any emergency kit.
I use my small 1-pint version for some day trips when a small fire and a cup of tea is perfect for lunch or a rest.
My 2.5 pint kettle resides in my car kit for when I am deployed to my EOC as a radio operator. In a wind storm or worse the large Kelly will serve as an endless boiler using downed wood, cones, paper, whatever as fuel.
These are pretty bulky, but not too heavy, and for a car kit or go kit are really just ideal.
Lee Valley is about the best place to get them in the US.
I highly recommend these kettles.
Ade....thanks for the link to my article too.
Ahh the pleasure of a hot cup on a cold wet day.......
