Seriously!! Ancient Persians Actually Developed Refrigerators In The Middle Of The Desert Before Anyone Else Did

Refrigerator is one of the useful inventions that has helped mankind. But, did you know that people of ancient Persia (now Iran) had sustainable refrigeration. They used the technology right where it mattered – middle of the desert.

In 400 B.C.E., Persia was surrounded by hot and arid deserts and people obviously needed cool drinks because of the heat. Even before the electricity, the engineers developed cold storage technology which allowed them to store ice.

They called the wonder the Yakhchal. It featured a dome-shaped hive rising above the ground and way below existed huge subterranean storage to keep food and ice. They froze water in the winter, and stored ice underground for use during the summer.

It was a long way to get down, but it would have been totally worth it. The Yakhchals were designed in a way to allow cold air to come in at the base of the dome. The Yakhchal’s tall conical-shaped dome sent heat upwards and out, therefore, the inside remained cold.

The facility was built out of sand, clay, egg whites, lime, ash and interestingly goat hair. They mixed these materials together to create a super water-resistant mortar called – Sarooj.

To fortify Yakhchals further, theypiled on Sarooj two metres thick from the base up. Some Yakhchals from ancient times can still be seen and the modern people would do well to make use of them in case of power failures.
