UL fuel efficient cook system

[AK Troutbum]

I think “cold” is very subjective and all relative to what you’re used to. I don’t usually hunt in cold weather either, but I’ve often been snowed on while goat hunting (temps down to probably low to mid 20’s), and I’ve never had any issues with the BRS. I have several different types of stoves, but for the last 7-8 years (I can’t remember for sure), I’ve only used the BRS.

Like I said before I don’t want to like the BRS as much as I do but it just works. I have who knows how many cheap to expensive canister stoves here that I’ve played with and the BRS pretty much is the one that gets used all the time.

Sounds like a BRS has a good place when the temperature doesn't get down too low. When I wake up in second rifle season and it's 0° outside, the old standby green propane bottle and screw on Coleman burner are the way to go.

I would love for a butane cannister of good mix and 3 oz burner to do the trick instead, but I know I'd have to take countermeasures to warm up the canister just to make a cup of coffee at 4 or 5 am.

At that point a remote canister stove running inverted would be the ticket.

Keep your fuel canister in your sleeping bag

Correct, there are simple things to keep the temperature up. Water bottle in a sleeping bag, along with a canister. Better yet, morning piss in a shallow container that the canister will fit in. It's enough to get the coffee done.

I've always felt the pressure regulator stove hype was pretty much hype with respect to normal temperatures. However, at "normal" temperatures such as 10 or 15° below freezing, has anyone seen a difference in simmering capability with regular versus non-regulator? I don't have a stove just to boil water, I cook food, not just rehydrate with boiling water, that capability is important.

My iteration of Ak Troutbums system. Couldn’t find the sterno pot so I went with the G3 and cut it down to the handles bottom rivet hole. It can still boil 16 oz of water although I rarely boil more than 10. I could probably save about 1/2 oz if I went with a different cozy.

Tested the efficiency against my brothers Toaks pot using the exact same stove, conditions, and water temp and this used 37% less fuel.

HX pot versus flat bottom pot of any material is going to win efficiency other than outlier type situations, which would require some thought to find if there is one.

HX pot with a stove that is known to be sub-par in windy conditions, is a tremendous wind break.

Efficiency is efficiency with respect to fuel. However ultralight and sacrificing practical functionality in conditions that are other than where the most ultralight system will function, becomes a gray area.

Huh?

I’m not sure what you’re saying but it’s not that hard to build a wind break with your backpack and gear. Just did it on a windy summit the other day. No issues.

Referring to your previous post. HX pot you modified was 37% more fuel efficient vs flat bottom (no HX) Toaks pot.

HX pot offers a windbreak and can make stove's that are poor in windy conditions perform better. Sorry if it wasn't clear.

As well, referring back to the title of this thread, fuel efficiency is a hard and fast number. There's really only a few combinations that have been devised that are the most ultralight, and they typically involve a stove that does not perform as well in all conditions. When boiling water is all your after, super ultra light systems are the way to go.

Agreed, a Windbreak can be built. Brings full circle to how much does the stove matter versus the ability of the user to create the right conditions. Maybe I bought the pressure regulated Windmaster and Green Peak 2 for no reason. Sounds like the BRS or similar lighter weight stoves cook things as evenly and as at low of a flame.
