After camping out recently in minus temperatures i experienced a slight problem with using my brass meths trangia burner.
Falling out of my Hammock in the morning doing the customary butt scratching the first thing on me mind was "COFFEE".The fire had burnt out and to get a fire meant gathering more wood(in the snow :0( ).So i turned to my trangia burner which i'd left out over night with meths still in it.Problem was it was too cold for the meths to vapourise,i eventually got round this by placing it in a pan and soaking the whole lot in meths stored in my kit bag to prime the burner.
The Survival Challenge Scenario.
You are stuck out in the bush in minus temp's with just your trangia brass/allu burner and only the meths thats stored in it.to survive the night you need to be able to light the burner to make your meal and hot beverage.
The challenge set is to design and make a cosy/cover or container that insulates your burner(with meths inside) that will take a spark with out the need to prime.
If you want you can also design and use materials that will also reflect the heat in summer to prevent rapid evaporation of the meths.
Brass/Allu burners in winter refrigerate the meths in the cold and absorb the suns heat causing loss of meths through evaporation in the summer,either way you are using more meths than necessary so this challenge is about efficiency and functional kit.
No rules for this other than designing either a cosy/cover or a trangia style burner that takes a spark after spending a few hours straight from the fridge.The meths must be stored inside the burner during refrigeration.
Good luck and enjoy.
