Скачать или смотреть How Ancient Persians Made Ice in the Desert

Discover the Yakhchāl, the ancient Persian refrigerator that brilliantly made ice in the middle of the scorching desert over 2,000 years before electricity. This incredible feat of ancient engineering used a combination of clever architecture, underground aqueducts (qanāts), and natural windcatchers to create a massive passive cooling machine.

In this video, we'll reveal the science behind how this cone-shaped structure could drop temperatures below freezing, allowing ancient civilizations to store food and enjoy ice year-round. It's a powerful testament to the ingenuity of ancient inventions and their mastery of thermodynamics.
