## Introduction

In Part II of this article I address the premise: If I chose the lightest stove in each category and used it as efficiently as I could, how would the cooking system carry weights compare for different usage levels and trip lengths?

In Part I of this article I assembled six different cooking systems (white gas, remote canister, top-mount canister, integrated canister, alcohol, and fuel tab) to be compared for fuel efficiency and carry weight. Then I tested the cooking systems under controlled conditions so the data would be as comparable as possible.

My goal was to answer the following questions:

• What is the real carry weight of stove plus fuel for different cooking systems?
• How do I calculate the amount of fuel I need for a trip?
• How much does fuel efficiency make up for stove weight on a longer trip?
• What is the comparative cost for stove plus fuel?
• Considering the fuel cost, which cooking system is the most economical and weight efficient?
