Today, when cell phones and laptops have penetrated even the most remote places on the planet, it’s hard to imagine a world before the “tech revolution”. This documentary from Mahdi and Mohsen Ahmadi introduces us to the ‘low-tech’ solution developed in Iran for producing and storing ice before the discovery of electricity and the spread of refrigerators. Iran’s traditional ice houses were both practical and beautiful, with some remaining in use into the 20th century. Of those that have survived until today, some are in a state of disrepair, while others have been fully repurposed to meet the needs of today.
