I used it a few times but didnt like being dependent in a battery. But the fan sure did get the fire going and made it burn hot.
Unfortuantely most of thr sites that zen stoves refers to are now gone

craigprice wrote:Wrt the complaint about soot on the pot noted by franco - yeah i see this a lot. I grew up in the era where we just lived with it.
Just get a cheapo aluminum billy 1 quart billy and forget it. Steelo can take off all the black but who cares. Use a freezer bag cover and forget. And if you who have concerns about aluminum cookware, then spend rhe $$$ and buy the Ti version.
But dont be afraid to put yr pot on a flame, fire, or wood stove. It will get black - but it doesnt hurt it and you can put it in a pot cover when you pack it out. And the black soot-oil residue it does clean off thr pot easily if you are worried.

I ordered something on impulse on Aliexpress about a week ago:
https://www.aliexpress.com/item/32986209563.html
...bought both, the 150mm and the 190mm high wind shields. They weigh only 13g and 15g.
The reason is, had this vague thought about using it as a wood stove, as the actual body of the stove, not just a wind shield.
Of course, it will have very limited strength to hold up a pot or mug, but I latched onto the idea that it might be doable. Have some wild ideas how it might be constructed.
I wasn't thinking of an air blower at the time, that was before I saw this forum thread.
Note, I do already have one of these that I bought years ago, a different vendor and only 110mm high. I did use it, as its intended purpose, as a wind shield for my meths stove. Will keep it for that purpose, as it fits into my titanium pot, along with the stove.

Re the oil - yes same - or if you put a dob of detergent on the bottom and smear it all around and up the sides that works too. It goes black with soot and looks messy but A cheap green scourer and some water removes it all quickly.
I’ve found that the pots clean in order from best to least: stainless steel, aluminium, then titanium. With stainless steel, it just breaks off easily and it’s as new after. With aluminium and a steelo it comes off pretty quick and easy too - it scours the surface clean. Almost as new with scoured patina. With Ti again need steelo and bit more effort - the surface is as new but usually with some slight discolouration in hard to get to areas eg handle flaps.
Btw I only clean up when I get home and am putting the gear back into order - not out in the field. Part of the routine of cleaning drying inspecting and putting the kit back in order.
craigprice wrote:Um yeah - I’m interested in this - what are you using and where do you get them from. Most ss pots I’ve seen are either too heavy or too expensive. If at that weight I could be re-invigorated to but a bunch and start tinkering in the workshop with new stove designs. That’s as close as you get to Ti!

Not UL and probably not Bushcraft either, but the idea of getting a fire started and pointing the blower at the fire to get it raging while setting up camp is a great idea. If I could buy one for canoeing, I'd drag it along for sure. Could also be useful for handling condensation in a tent.
Regarding heating rocks, (sorry to digress) but I was reading about Aboriginal rock circles in Vic the other day and couldn't help but think they weren't designed as a wind break but to radiate heat later in the night/early morning. So next level when it comes to using rocks to keep warm.

BarryK, I think you will be able to 'fold' strength into it. If you keep it squat (about twice the thickness of your sticks) and make a bridge across the fuel opening. It will be a fun challenge. Tim

For me, as a walker, I don't think it provides a benefit in the areas I walk. That said, I can see that in areas I have been, it would have been a value due to the environment and available fuel. In essence, it becomes an artificial "Dakota fire pit" and makes more effective use of the available fuel. If I was going to build the same, I might try to construct a large enough thermocouple to get the voltage from the fire itself rather than a battery, though I can see why on a short trip the battery has the edge. Kind of a DIY Biolite rig. My main concern with natural fuel fires is that the local area really plays a factor, and from both an NLT and "Can't be bothered to plan" standpoints, fuel stoves solve that for me.

You may need many of them to get the power required, a group of thermocouples is call a thermopile, this is usually configured to get more voltage.
The alternative is to make the thermocouple large .. but that requires the temperature difference to be consistent over a large area - not something you get with a camp fire.
Personally .. I'd not spend my time on it.

Whole stove, without canister, 45 grams. Works sub-zero and in the snow.
And SO much faster than wood fire.
