Re: how do i make it warm
Fires are problematic and "cheap" rules out fuels in general.
And forget any kind of alcohol heater, the amount of water vapor they product will be truly memorable.
I'd really suggest layering up in some warm clothes from the thrift store. A good wool watch cap (or two) and insulated boots, moisture-wicking long johns, and you've got the safest cheapest solution.
