Re: high altitude stove
Ok, Iím going to put my 2c in, even though its late for this thread, but I was just using an OmniFuel stove made by Primus a few days ago in 35 deg.. This thing is a multi-fuel stove, can use butane/propane gas, or liquid fuel(white gas), or even diesel/petro and gasoline. It is a backpacking stove, is very light and compact. Some guys on here have said they have no problems using gas/butane fuel in cold conditions, but from what Iíve read the gas fuel has trouble burning efficiently when you get down into the 25 degrees area and colder. You would need to carry the gas canister near your body in super cold conditions and shake it prior to use. (I canít attest to use in high alt though sorry). The gas canisters work best, you just make the connections open the valve and poof, your gtg.
The liquid fuel is a great all-time fuel, but really accommodates in the colder temps (such as far below freezing), BUT you have to prime the burner to get it hot enough to get it torched up.. you also have to carry a fuel bottle which comes in .35 or .6 or 1.0 Liter bottles, which still are no big deals.., I used the .6 L and is still pretty compact. The system is EXTREMELY versatile and WORKS GREAT in all conditions, even in windy conditions. The omni fuel in my opinion is just an all-round great system. The jet on this thing is great , I just donít see a huge downside to this system, Iím sure there are others that are very good, but this thing is built like a tank, yet light and compact. I would recommend to ANYONE ! anyways thatís just my 2cent review.
