JetBoil PCS: Radically Improved Fuel Efficiency
A principal function of a climber’s stove is to melt snow and ice, producing drinkable water. Hot soup, coffee and the occasional hot water bottle are perks, but on long trips fuel weight adds up. For Alaska I budget 48 ounces per day for a group of six–about 8 pounds of fuel each for a three-week expedition. While toiling with such donkeywork I imagine the ideal stove, where every calorie of fuel burned produces the maximum amount of water. This process, called heat transfer efficiency, inspired the design of the Jetboil Personal Cooking System (PCS).
