Am getting into planning and plotting thoughts for a couple of remote trips. Now given the peculiarities of the locale (not going into specifics), I can't rely on biomass for stove fuel.
So I find myself pondering the two obvious liquid fuel options that are available: Meths and Petrol. Now the petrol stove is 150g heavier than the meths stove. But, if my understanding is correct petrol has a higher energy density, meaning you need less of it for a given amount of heating. The question I've got is this: How long would I have to go between refuelling opportunities for the extra weight of the petrol stove to be off set by the higher energy density of the petrol?
I am also wondering if the controllability of the petrol stove - you can turn it off the moment that the water is boiled -offers a significant enough efficiency saving over a meths stove that you can't turn off but instead have to let burn out, to justify the weight of the petrol stove on longer trips.
Has anyone else done the maths on this one?
Thanks
Julia
