I think you're right: it is a viable option. It's hardwood, after all, and puts out a lot of heat. The only question, from a planning perspective, is whether it gives the most bang for the buck. But in an emergency I'd be very glad to have it. And of course it's easier to justify because it's dual purpose (always be prepared for Steak).

Anybody know an inexpensive, bulk source for charcoal?
