Comparison....

The stove, not the folding cup of water..

Home made cat-can meths stove that I've been using for the last 6 months or so:-
Image

I ran a comparison. Gas stove, 3 minutes to boil the cup of water. MYOG meths stove, 3 minutes 20 seconds for the same amount of water. No need to carry that gas canister to save 20 seconds, I reckon. Especially since the meths stove fits inside my pot (with tea bags, powdered milk, straws of washing-up liquid, a lighter, windshield and a pan scrubber) but the gas stove doesn't.

Always fun to carry out little experiments like that :smile:. Did a bit of WE packing earlier (I'm keen) and my complete breakfast kitchen now weighs just over 200g - Stu Hyperstove (TM), windshield, pad, eating pot, 18ml ethanol, spoon, matches, porage, ovaltine, all fitting RussianDoll-style into 400ml Ti mug. 330ml cafe/pub milk picked up during previous day. And of course the stove is totally silent. Mine's slower than gas, so along with the silence it makes for a very relaxed and contemplative breakfast.

Aye and that's why I can never consider a gas stove to be truly lightweight. Faff free, fast and easy to use - certainly but a canister rules it out from the lightweight running even if the actual stove weighs very little.

Interestingly (perhaps) I was informed today by a competitor in an ultrarunning event that even though a stove isn't mandatory, the organisers wouldn't allow him to take an 8g stove as it was too light. The irony wasn't lost on me :roll:

Just weighed one of my small canisters and it's 141g. Probably just over half the gas left in it.

150ml of meths is 119g if my maths is right, plus the weight of the bottle.

Difference is negligible n'est ce pas?

'too light' :???: :smile:. I also only take 3 matches and a tiny piece of strike board. If i can't get going with 3 (or even 1 really) then I don't deserve breakfast :wink:. The only thing I could really do with (apart from, obviously, a full sized down pillow that only weighs 40g) is a complex but foldable system of tiny mirrors that can be installed around/under the windshield so that I know the stove hasn't gone out without lifting the pot up.... I know I could just hold my hand over it but toasted fingers don't feature on my brekkie menu.

re '150ml' - Yeah but for one breakfast (eg BaM) can you buy a tiny gas canister with only a tiny one-breakfast amount of gas in it? :wink: My breakfast fuel including bottle weighs 22g (and the stove only weighs 18g but could be just 8g - a Pocket Rocket is 77g or more which isn't included on your side of the equation). And - you're soon stuck with an empty single-use canister (maybe they should have the equivalent of a plastic-bag charge on them :wink:). AND - the problem of never having a canister with the correct amount for the trip which means often taking a spare canister. Not worked it out but even from purely the weight pov you're looking at 3 days or more for the balance to tip towards gas? 18ml of ethanol boils me 400ml water. And that's never mind the big-kid excitement and pleasure I still get from firing up a Stu Stove :smile:.

Yeah but it probably weighs nearly 100g empty. If I'm not anywhere I can easily dispose of it then I'm carrying that about but more importantly, I'm having to find somewhere for it to live.

I've never completey empited a canister on a trip. Probably never will come to think of it as I don't bother with a stove any more. :lol:

As you were. :-bd

Scaredy cat, you've run away now! Where's the fun in that battle!? :lol:.

Of course you're right - the lightest stove is the one left at home in the cupboard :smile:. A tenner for a greasy-spoon fry-up is probably only about 2g :wink:.

Unless you are racing then the extra 20 (or thirty, forty, whatever) seconds are immaterial when compared to the time spent at a bivy or in a bothy especially at this time of year.

I'm sure I've seen on one of the American backpacking/hiking forums or blogs a somewhat OCD dissection of fuel use and at what point the weight of fuel for a meths stove becomes greater than that for other fuels. (Meths is less energy dense than propane/butane gas or petrol) For trips of a few days it's definitely the winner.

Here ya go Reg, a cross section of my meths burner collection, from retro to a more modern take, from MYOG to buy-it-from-Stu. I have another 15-20 of these things in various boxes around the house.

Image

The little one on the right is my current go-to, as you can put enough meths in to boil 700ml of water three times (no, not the same 700ml ...) and snuff the flame when it's done. It's part of a system from StorminStoveSystems which is essentially a custom two-piece Caldera cone that rolls up and fits into the pot with a cup, the stove, lighter, folding spork and a small piece of tea towel. It does 700ml in around 7 minutes depending on the temperature. It's a pot stand and windshield all in one and very stable it is too - good for gullumps like me who regularly knock cups off their side-burner stoves. I've recently ordered one for my 450ml cup, which should give me a very light and compact way to make breakfast. I may even weigh it when it arrives, time it to boil and report back.

Of course, my cooking kit on Sunday night weight about 10kg and included the firewood I carried with me, a hatchet and saw, a big pot, loads of food, a loaded Trangia for breakfast and various ways of starting a fire. And not to forget the grill strapped to the side of my bike. It was a far more congenial way to have dinner than waiting for boiled water to rehydrate a handful of gravel in a bag, but I wouldn't want to have to lug it halfway across Wales.
