Thanks for the clarification Tom. I wonder if dog mushers, not during the iditarod, carry their own fuel?

I agree that some fuels do contain more BTU per unit. I know that for my needs, alcohol is much easier to useand has plenty of oomph for the conditions I use it in.

ethanol has 80k BTU/gal and gasoline is 199k BTU/Gal. so I need 50% more ethanol to give me the equivalent heat content of gasoline. so instead of 6 oz of alcohol, I need 9oz to be equivalent to someone with 6 oz of gas. So for those extra 3 oz, I don't have to play with a fuel pump, a heavy fuel bottle, or a heavy stove. No parts to keep clean, no priming.

Mushers in general carry their own fuel. A lot of the places out here they have no choice because there is nothing nearby - no roads, no anything. But they choose to use the alcohol stove (aka dog food cooker), I'm not sure on the reasoning.

according to my quick check it would take 14.9 oz of the ethanol at 80k Btu to equal 6 ounces of 199k Btu. Considerable.
Check your math.

Thanks Jim. My error was a typo, not my math. It is 119k BTU/Gal for gasoline. Sorry about that. Of course those numbers do vary. I have also seen gasoline quoted as 114k btu/gal.

Heather, I suspect that they use it because it is safer than white gas-less volatile, so less likely to have a serious accident with it. I also saw something about it being less poisonous, but Heet is methanol, which is highly poisonous to humans, so not sure about that claim.

The cooker I saw was basically a pie pan inside a bucket, so burning white gas in it would be a pretty iffy proposition.

Powermax canisters. I had a good, cheaper source for these canisters on eBay, but they finally raised their prices. I was getting them with shipping for a little over $11 a canister, with a order of 3 at a time max due to Postal regs. I have 17 canisters, so I guess they better last me. I also have a line on some smaller ones cheap, just need the guy to package them and charge me for the shipping. Last weekend I finally took my Xtreme stove out, but it was only used a little, due to the food I took for a quick overnight bp trip.
