I always look at the Kelly Kettles but never buy one. I'm skeptical of their versatility. Because the water is in the jacket on the outside of the chimney, it's not handy for cooking coffee or soup or stew.

I've seen several variations of the Sierra Stove, which uses natural fuel that's whipped up by a tiny fan. Seems more practical -- basically a campstove. I'd like to try one (or make one) someday.

My interim solution is one of those BBQ briquette starters (basically a steel chimney with a handle) that I bought for $5 on clearance from WallyWorld.
