[quote="crollsurf"]Let's get back to UL then. Alcohol stoves are lighter for overnight. After 2-3 days, gas is lighter.
It just happens that most of my trips have been 2-3 days long but even for longer periods it isn't a clear case of what does weight less or works best.
For example on a 6 days trail I did in the US I took 500ml* of ethanol and finished that trip with a little bit left, maybe enough for 2-3 cups of coffee.
So to me that was 475g* for the fuel and container, 55 g for the Caldera Cone (Ti) stove and snuffer.Tot 530g
(the previous hike was 5 days long, same initial weight , came back with leftover fuel. Same place /temperatures)
If I had used gas , I would have taken a 220g canister (working on half the fuel in grams needed , but I do a bit better with the CC) that is 350g and a light gas stove at
50g add a windscreen at say 20 g , gives me a total of 420 g, so the gas wins.
However if I had been on a
7 day trip with gas I would need a 220g plus a 100gcanister , that is a tot weight of 550g plus 70g for the stove and screen
so 620g.
With metho , at my consumption of 80g per day, that would be ,for me, 55g for the stove ,30g for a 1l container and 560 of fuel , tot 645 g, so not much difference at all.
Obviously in that situation you use the kit you prefer to use but I just wanted to point out that the weight ratio is not all that linear with gas because of the limitations with the size of the canisters and their weight. Just to think that you use half of the weight in fuel (or whatever ratio you think it is) does not always work.
* ethanol is 789g per litre.
**Using the 360 Degree stove shown by Commando (at
125g) would give metho an advantage on more situations.
** Windscreen for the gas stove too because gas stoves suffer too in the wind , so to keep a reasonable same-same scenario.
***I should point out that because I use a snuffer, I put in the burner more fuel than I think I need and snuff the flame out as soon as I get the water temperature I want (I don't need to boil for a cup of coffee) So I can then recover the fuel leftover.
****I have 3-4 cups of hot drink plus cook dinner every day. Some only have one hot cup and one hot dinner per day, so it depends.
In the photo, the CC kit I used . The plastic kit holder is my plate/cup and the container I use to "cook" my dinner in. I do the same with gas.
