yep, we do, and so do 500.000 people in Mongolia.

I remember seeing a documentary about the reindeer herders in Siberia, Nomads who live in yurts . . . it was interesting because it showed some of the aerodynamics of the traditional structure, how even the fiercest winds would glide over the wide, low structure, and the snow did not seem to compile on the roofs . . . of course the temperature were severe with wind chills nearly 100 below zero, but with the inner yurt lined with felt blankets the coldest temps within the yurt were 40-50 degrees . . . then they had these enclosed beds (like a canopy beds, lined with felt blankets), they slept nude within this chamber as it was nearly body temperature inside. The inner dynamics of the yurt, with stove/fire heat, and circulation of air with the low, open circular structure, and breathability of the natural materials all work together to make these structure ideal for severe weather; they are what the Nomads developed in response to their conditions.

I found the inner bed chamber and interesting feature . . . it makes sense, like dressing in layers, that the more insulation layers created would increase heat . . .

I live full-time in a yurt, and through a coupla winters now.
Keep the woodstove burning.
If it goes out, you'll freeze.

But then I've only got that reflectix stuff for insulation. Shoulda added some yak-fur, I s'pose.
