How Inuit Igloos Stayed Warm at –50°C Without Fire

How do igloos stay warm at –50°C without fire? In this video, we break down how Inuit igloos stayed warm using nothing but snow, body heat, and a tiny seal-oil lamp — and the engineering behind it is smarter than most modern homes. You'll learn: • Why snow is a great insulator but solid ice is not • How Inuit builders find the perfect wind-packed snow • The spiral block design and the "king block" that locks the dome • Why the entrance tunnel works as a natural airlock • How the raised sleeping platform traps warm air • How the qulliq (soapstone seal-oil lamp) and the ice glaze keep heat inside An igloo isn't warm because of a trick. It's warm because every layer is designed to stop the heat that's already there from escaping. This is Inuit engineering at its best, and the same physics is used in modern cold-climate homes today. 🧊 Question for you: if you built your house from snow blocks tonight, would it really be warmer?
