I have two of the Kifaru wood stoves and absolutely love them. Does require wood though, and there are hunts, open country caribou for instance, where wood is scare or non-existant.

For a number of reasons I am leary of non-vented liquid fuel or gas stoves. Death from CO poisoning for instance, would be inconvenient. Being dead AND wet due to using a non-vented, liquid fuel stove would be really irritating.

It would be interesting to explore a hybrid option ... a vented liquid fuel or gas stove or a mod to use with a wood stove when the situation fits.
