Good Thread. I hope you guys find some alcohol solutions.
Use blackened aluminum pots. They will naturally blacken
over a wood fire; clean the excess blackening, but leave a
light black coating (hard finish) on the pot.
I thought kerosene had about 50% more calories than alcohol,
and would therefor be better for survival purposes.
Have you searched for DIY kerosene stoves.
One primitive stove is the tuna can with a spiral cardboard
insert, which acts as a (huge) wick.
Also, I question: do you really need to boil the water?
Would 170 degrees F be OK?
Since I hate the smell of kerosene myself, I would prefer
alcohol for inside a tent or vehicle. IMO alcohol is a
little safer in a closed space.
