Dear Yury and all, the use of slow growing pine logs for permanent housing and "holyday" purposes, are still considered as a "high staus" way of buliding houses in Norway. Nearby the "Olympic City" of Lillehammer you will find hundereds or even thousands of this type of "housing" worth millions of NOK, each. Slow growing pine logs will not easily give "cracks" when they dry and by removing the core of the tree, you will also reduce the chance to get "cracks". This type of housing was created by the "Vikings" in Scandinavia from the kingdom of "Svea" (Sweden) and the knowledge even brought eastwords by them sailing in their quick warships up the rivers of Russia to Novgorod, called "Holmgard" in the old nordic language and all the way to the Caspian Sea.
"Slash and burn" or "Chitemene", called in the local language "Bemba" in Zambia, are well known metodes to cultivate land for "nomadic" people in Africa, baned by the introduction of the industrilzed fertilizer. Crispin; why not introduce efficient and low poluting wood stoves in Ulan Bator, as well..........? You will find a lot of different types of pelletstoves, even produced in Norway, based on technology closly related to gasification and pyrolysis. The world is moving "ahead", but very slowly....................
