Engineering students build a cooling system for people without access to electricity, using the different methods animals use to keep cool
Quelle:: University of Calgary
A food preserving system, which does not require electricity, was created by four students from the University of Calgary Schulich School of Engineering. They examined the different strategies animals use to regulate their body temperature and cool themselves, and mimicked them.
The students' device, known as the WindChill, operates with a funnel that draws outside air into a pipe, which is immersed in a fluid. The fluid evaporates, cooling the air, which is then sent to an underground refrigeration chamber.
Every phase of the cooling mechanism mimics a cooling strategy used by animals: the first step was inspired by termites and corals; the second one by elephants, which wet their ears and let the water evaporate to cool their skin; and the final step came from burrowing animals.
This nature-inspired refrigeration system is environmentally friendly and cheap to produce, making it a perfect solution for people living in poor and remote locations that do not have access to electricity.
