I have chosen to create an alcohol stove following a modern and minimalist camping aesthetic. Since I was a little kid I’ve been intrigued by the designs of minimalist camping gear such as stoves, pots and pans, silverware, and multitools. This summer my buddy and I made some crude alcohol stoves from aluminum cans and the experience really piqued my interest in making a more precise version. I want my design to have a refined and modern look, while being compact and highly functional.
Alcohol stoves can be made in a variety of different styles, ranging from very simplistic to moderately complex. I plan on following the general concept of an “open jet” stove. Below is a cross-sectional view of a basic “open jet” design.
The dark blue represents the fuel (denatured alcohol), the lighter blue is alcohol vapor, and the lightest blue is flame. To use an “open jet” stove the fuel in the central reservoir must be ignited allowing for the stove to prime itself. Once the fuel has been lit, the stove begins to warm up and vaporize the alcohol. The vapor pressurizes within the side chambers and begins to flow out of the top from small holes, where it is then ignited from the central flame. Depending on the design of the stove a stand may be required to hold the pan above the flames.
From a functional standpoint, I want my design to have high heat output with variable temperature control as well as a built in stand. Aesthetically, I plan on the design being sleek and compact when not in use.
The most critical aspect of this project is not necessarily one part, but rather the manner of construction. The whole design must be constructed very precisely for the stove to work really well and be reliable. Additionally, aluminum cans like to tear and crumple making them really fun to work with (sarcasm). I have a feeling I will be making a handful of prototypes to hone my skills.
