Good solution for a thru-hiking blogger who camps below treeline, has good cell coverage, and needs to post before getting to the next resupply town. Should be a huge market for that crowd.
Joking aside, the technology is really cool and I like wood burners, but the 33 oz weight would make this the heaviest item in my pack including my pack. Saves on fuel though for long hauls.
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.
