new refrigerator works without electricity

A clever new refrigerator invented by students in Canada, keeps food cold without electricity.

A team of students in Canada created a cooling device that is cheap, portable and works without any electricity, making it ideal for people in remote and rural areas.

WindChill Food Preservation Unit, it is a tool for not only keeping food at low temperatures, but also for changing the lives of people that use it.

Michelle Zhou, one of the students from the University of Calgary, told CBC News:

“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.”


The cooling mechanism is inspired by temperature regulation approaches seen in mammals and insects and is a new way of approaching issues in the food system. Coral and termites inspired the first step, kangaroos, bees, and elephants the second, and lastly meerkats and burrowing animals and leaves the third. In our process an intake structure passively draws in air warm ambient air and injects it via the venture effect it into a pipe. The second step delivers the air into the evaporation chamber, where the pipe is immersed in a fluid. The fluid evaporating from the around pipe cools the inside air and lastly the third step involves the cooled air entering the refrigeration chamber where food is stored.
