As a result of an internship program between El Domo - Product Design Agency and URL-University in Guatemala in cooperation with PUCE-University in Ecuador, the former students and now graduated Product Designers "Margarita Cajas" and "Gaddy Mayen" from URL-University developed an Open Source Powerless Fridge.

Thirty percent of the food grown for human use is lost or squandered every year. Agronomic systems, in which we are highly reliant on the elements of nature, are the foundation of our society. Therefore, it is crucial to develop methods of extending the shelf life of food.
No matter how the food is grown or transported to the consumer, if any of it goes to waste, so do the associated time, money, and energy.
This food is vulnerable to a wide variety of hazards, the most significant of which is contamination by insects; nevertheless, even if these are avoided, the food still faces difficulties in storage, transit, and refrigeration.
Without electricity, many pre-industrial societies overcame this challenge by devising methods to preserve food for longer periods of time.
Since a large portion of our user base does not have access to an electrical refrigerant or even electricity, this inquiry provided instances of our predecessors' responses to the aforementioned difficulty.
The following suggestion is based on the idea of a chilly chamber, the key tenet of which is that the protagonist must be helpless and have easy access to supplies. Based on the physical-chemical phenomenon of evaporative cooling, our plan uses water evaporation to mitigate excessive heat and extend the shelf life of perishable goods.
