I'm gonna have to call you on that one. You would have to try damn hard to puncture that nalgene bottle I keep the fuel in. I'd also care to remind you that no parrafin made will burn as hot as denatured alcohol. The denatured also has no smoke and the flame is very low light, not to mention the pot would mask the blue flame it makes. As for concealment and function, this stove design is far smaller than a #10 can and much easier to pack up should you have to use your bug out bag. For nearly free this design cannot be beat.alchohol, or any liquid, can leak or spill and most can evaporate, and it's not at all hard to puncture plastic bottles. metal containers, if thick enough to be durable, are quite heavy. A paraffin "can candle", from NuWick, thru CampMor, makes far more sense. you can make your own, for very little money, much larger and producing much more heat, once you know how. after the melted wax cools and solidifies, no worries about leaks, etc. Paraffin is about $1 a lb online, and lasts a long time. you can have 7 wicks burning at once, in a #10 can, with a 2 gallon can around it to hold off the wind a bit and concentrate the heat and it will QUICKLY boil an entire gallon of water, with almost no visible flame or smoke. you can bury a 1/2 drum of paraffin, use mop strings as wicks, and be able to cook your food for a year, without having to pick up or chop wood, much,much more discrete, guys.
You have to love them, to me this is a big plus because I won't have to run around on my bad legs gathering fire wood and groveling over the dampness to get a fire started when I could just whip this out and dry some wood off and get a fire going. Or if trapped in a cold building I can just stop and light it up. Amazing how much heat that alcohol gives off. I'm about to go rework my BOB and that one stove and cookset is definitely going to save me about 2 pounds.Talking about these mini stoves reminds me of the "fond" memories of eating C Rations during '68. Only ate them cold once as I picked up a good supply of Sterno the next day and made a stove top out of an empty c ration biscuit can by using a church key to make vent holes. The biscuit can fit just just in the flange of the Sterno lid. Carried it in my ammo bag and used until I returned to the world.
