Thank you, JIM and PC2K for the warm welcome <img src="/images/graemlins/smile.gif" alt="" />
I think only Angel to a degree and williamlatham absolutely grasped my point ! <img src="/images/graemlins/ooo.gif" alt="" />
These cooking devices are indeed ENCLOSED FIRE SYSTEMS, bar the Grilliput. There is absolutely no "open fire situation" as compared to let's say a camp fire and there is also no firescarring left on the ground.
This is the exact same thing you are using except the fuel is a lot different/free/in abundance everywhere! <img src="/images/graemlins/wink.gif" alt="" />
Also, as williamlatham points out these things are extremely fuel- efficient ! Three or four pinecones, three handfulls of twigs or a read paperback novel IS ALL IT TAKES to cook your meal or boil you water VERY QUICKLY. No kidding ! I'm not burning up whole trees here, this is exactly my point <img src="/images/graemlins/grin.gif" alt="" />
Damp wood/woodlike (pinecones; bark; grass, etc.) fuels also are not a problem since the "enclosed furnace/ chimney" system negates this problem same way a chimney-type charcoal starter for your bbq does.
The Grilliput is an entirely different story, as this is actually (albeit a very handy one, since it packs away as small as it does) a basic bbq grid on four legs and does use an open woodfire or charcoal fire. It just made sense to me to add it to the kelly kettle/trailstove combo because it fits inside this combo and uses the same (wood) fuel. <img src="/images/graemlins/tongue.gif" alt="" />

So again , howcome so few of you use them ? Is it because many people are not aware of their existence, or other ?
