Esbit fuel is a stable variation on the excellent, but rapidly degrading Trioxane. The increased effort in lighting is the price for increased longevity. An esbit tab is also an excellent PSK item for the critical second stage in fire building between tinder and fuel. Now your second step is to acquire an empty aluminum can. Drink the contents and eat ( do not polish can with ) some chocolate. Now take said can and experiment with fabricating windscreens to improve the Esbit's efficiencey. I found two flat side screens with a small folded base both fit inside nicely and block heat loss placed on the two open sides. You can readilly cut the can with scissors ( not your mother, wife or G/Fs prized pair for sewing if you wish to survive) or, barring that find out how handy that Becker, Swamp Rat, Atax, Cold Steel Masai lion spear etc. really are <img src="/images/graemlins/grin.gif" alt="" />
