Как Иглу Эскимосов Сохраняют Тепло При −50°C

You probably think of an igloo as an ice hut, as cold as the outside. But at -50°C, a person sleeps naked inside—and is hot. This isn't a myth, but pure physics. The dome is the most perfect shape for the Arctic: the wind flows around it without finding a foothold, and the surface area is minimal (30% less heat loss than a square house). Snow blocks are 85–90% air, the best natural insulator. After assembly, moisture from breathing freezes on the walls, creating a three-layer protection: wind protection, insulation, and vapor barrier. The main secret is the trap entrance. The tunnel is below floor level: cold air is heavy, it spreads along the bottom and cannot rise inside. The wind loses its strength at the bends. Inside, there are two climate levels: on the raised sleeping platform, it reaches up to 16°C, while below, there's a cooler area for storing meat. A window made of fresh ice lets in light without escaping heat. The igloo is a masterpiece of engineering without a single nail. Snow performs ten functions simultaneously. Modern architecture is only now realizing what the Inuit have known for millennia: a good home is not one with too much technology, but one with nothing superfluous.
