Yakutsk, Russia, is the coldest big city in the world. In winter, the temperature drops well below -30 ° C. A freezing cold that conditions the life of the 300,000 inhabitants, starting with their houses, built on a layer of perpetually frozen earth, the permafrost. “The stilts raise the house and prevent the heat that comes from melting the ice below. Otherwise, the ice melts and the house collapses.”, explains a resident, Dimitri Petrov.
Inside his home, it is 25 ° C. With his family, he spends almost all of his time there. The heating is constantly working and it is better, because a simple draft can turn into ice. With this cold, no need for a freezer, the food is simply stored on the balcony. Their car also had to be adapted. It starts automatically as soon as the engine temperature drops below 9 ° C. It then runs for about forty minutes to prevent the oil from freezing in the engine.
