Prob spelt that wrong but... so had a flat cat stove snow leopard set up on an MSR TItan kettle for many years ..so on the hill but shelters under my trap with a foil piece underneath stove i tend to need 20 ml of biofuel to boil up say 500-600 of cold water lets say air temp of 3c and water came from a cold running beck ..so is there anything thats much more effient ?
