Why Mongolian Yurts Didn't Freeze in -40° Winters?

It's minus 40°F outside. A felt tent is the only thing between you and the steppe. How is anyone surviving in there? This video breaks down the real engineering inside a Mongolian ger — the circular portable dwelling that kept nomadic families alive through some of the coldest winters on Earth. No nails, no foundation, no chimney. Just felt, geometry, and a few thousand years of getting it right. • Why the circular shape uses less wall surface than any other floor plan — and why that matters at minus 40 • How layered felt traps still air the same way modern insulation does, and why thickness changes everything • The one rule every ger door follows, and the physics reason behind it • Why the stove sits at the exact center — and why a stove against a wall is a completely different problem • How bodies, animals, and clothing were all part of the same heat system • The deadly Mongolian weather pattern called a dzud — and what it revealed about the limits of even the best shelter • Why hundreds of thousands of people in Ulaanbaatar still live in gers today, and what that costs them This video is for general learning.
