This is one of a number of stove designs based on the TLUD (top-lit up draft) configuration. My current favorite, the Woodgas Survival Stove (Ebay item No. 190413891341) works on natural draft, no fan no batteries, and is now the only stove I carry on most trips.
Recently, on my latest AT trip, I watched a couple of hearty woodsmen hunting up firewood with ax and machete while I gathered and filled my stove with fuel from where I was sittng, Colin Fletcher style, on my groundsheet. Boiled tea water and made pasta dinner on one fill. The thing is 9 ounces, about 6 with extraneous lids removed.
That's not bad, considering there are zero fuel/oz/miles to add to that. The pot stand will work with fuel tabs, in case you consider this a fire rather than a stove for no-fire zones. SO I carry about 2 oz of pine litter when I know I am headed to cold camp. Oh, and I can cut up my used plastic bags for an excellent fuel when mixed with something woody: completely combusted with no plastic odor.
I consider it a stove for all purposes, but I have never had that conversation with a Ranger yet.
Wherever you go, there you are. SPOTMe!
