The refrigerator is a common household appliance that most people in the modernized Western world come to expect to have in any home or rental property.

 It’s a pretty useful tool the refrigerator, it keeps all of our foods fresh and lasting long.  Unfortunately, not everyone in the world has the privilege of using what most of us consider a common amenity.  There are 1.3 billion people in the world who live without electricity, meaning a refrigerator for them is out of the question.

A group of students from the University of Calgary came up with a new refrigerator design that successfully keeps produce fresh without using electricity.  Michelle Zhou, one of the students who worked on the project said, “We thought it would be good to decrease the amount of food waste in the world, and we came up with this design because it’s easy to build and the materials are relatively cheap.”

This new refrigerator has been dubbed the “WindChill Food Preservation Unit.”  It connects an air tube to an evaporation chamber, which is connected to a sealed refrigeration chamber, which allows for the evaporative cooling process that keeps contents cold.  The device won first place in the student category of the 2015 Biomimicry Global Design Challenge, which asks researchers and students to think of new ways to improve the global food system inspired by nature.
