How to Make and Use The BYU Solar Cooker/Cooler

by Steven E. Jones, Professor of Physics at Brigham Young University (BYU), with Colter Paulson, Jason Chesley, Jacob Fugal, Derek Hullinger, Jamie Winterton, Jeannette Lawler, and Seth, David, Nathan, and Danelle Jones.

Introduction

A few years ago, I woke up to the fact that half of the world’s peoples must burn wood or dried dung in order to cook their food. It came as quite a shock to me, especially as I learned of the illnesses caused by breathing smoke day in and day out, and the environmental impacts of deforestation -not to mention the time spent by people (mostly women) gathering sticks and dung to cook their food. And yet, many of these billions of people live near the equator, where sunshine is abundant and free. Ergo…

As a University Professor of Physics with a background in energy usage, I set out to develop a means of cooking food and sterilizing water using the free energy of the sun. http://solarcooking.org/plans/funnel.htm

The Physics of Everyday Life

Because we live off-grid, and build our own energy systems, there is a need for a good understanding of physics. Most physics texts are heavy on theory, and dry as a piece of straw. We have found an exception. Written in an easy to comprehend style, and filled with everyday examples and explanations, How Things Work by Louis A. Bloomfield is a reference that should be in your personal library if you are in the least bit curious about how the things around you work, and it’s a necessity if you are designing your own energy systems.
