portable stoves

...

There is a chance though with separate bottle stoves (the one with a hose attached to the burner on one end and the canister on the other side) as long as the burner has a generator tube and the canister can be set up upside down. The propane on top (now the bottom of the canister), pushes the liquid butane down the hose and... it gasifyes on the generator tube. You need to run them for a minute or so with the canister in the upright position though to bring that generator tube up to temp...

Exactly that. I use one of these a lot for convenience. Those sort of methods allow me to push it a bit further below 0. Still, as I said in a recent thread here, I do jump to liquid fuel when the needle really drops.

Notes:

“Esbits are the way to go if you're only boiling water and can deal with the horrible residue they leave on the surrounding stuff/cookware.”

That's one of the reasons I don't like Esbits. Hexamine sucks. Trioxane is better.

“There's also the issue of properly disposing used cannisters as they can't be refilled.”

Pretty sure Harbour Freight used to sell the device needed to refill them. Dunno if they still do.

Beautiful one! And yes, that's one of the stoves I was talking about. Still a problem remains with gas canisters... since the presure inside the canister is not consistent through the life span of the gas. The lesser the gas, the lower the presure... and the les heat output.
Liquid fuel stoves don't care wether they are full, half full or almost empty. As long as you are carefull to pump accordingly... you are good to go.
I use an Primus Omnifuel since I like the feature of having two valvles... with the one in the burner I can actually simmer just like I was using an LPG stove. You couldn't do that with the Multifuel. I also checked the MSR Dragonfly (also with two valvules) but it was heavier and bulkier.

Talking with some people who have been in the Himalaya I have been told that peple there actually REFILL the canisters... which, of course, doesn't assure you the quality of the fuel. Probably all butante, which is cheaper and easier to find than propane... Go figure what happens when someone tries to cook below 0 with one of those
