As we’ve often noted hot water in the wilderness is something that is close to priceless. We’ve seen numerous methods to heat the water in a pot or other cooking vessel, but there is another way – by heating the water from the water from inside out.
Heatstick takes the old concept of heating a rock and putting it in water, and applies it to a lightweight stick that draws on a propane and butane mix to heat up water in a singled container. It is able to turn cold water hot through the use of an aluminum Fuelstick cylinder. This can boil around two gallons of water, and the Heatsticks are available in different temperature ranges for varying conditions and uses. Video after the jump
