For heating, there is also a traditional type of fireplace that's been<br>used in Korea for centuries. It's basically a firebox on one side of<br>the house, with smoke tubes that travel under the floor and a chimney<br>on the other side. It's called an Ondol. Check out:<br><br>http://en.wikipedia.org/wiki/Ondol<br>http://www.koreabrand.net/en/know/know_view.do?CATE_CD=0005&SEQ=2320<br><br><br>Arclight<br><br><br>On Sun, Nov 18, 2012 at 9:02 AM, Lee von Kraus <<a ymailto="mailto:leevonk@gmail.com" href="mailto:leevonk@gmail.com">leevonk@gmail.com</a>> wrote:<br>> To stay warm you should use a very efficient heating system which transfers<br>> heat primarily to your bodies and secondarily to your habitat. The general<br>> concept for doing this is to have glowing coals inside of a sealed, highly<br>> insulated 'container'. For indoor implementation this is called a 'korsi' or<br>> 'kotatsu. For outdoor use this is called a
'fire bed'. Here's a description<br>> of the two:<br>><br>> For indoors use a Korsi:<br>> 1) Get a large metal (non-galvanized) container that has a tightly sealing<br>> top for it.<br>> 2) Get a lot of wood ash.<br>> 3) mix the ash with water to make a paste.<br>> 4) coat the inside walls of your container with a ~1 inch layer ash paste.<br>> Do not put paste on the containers lid. Let the paste dry. This ash border<br>> will act as a highly insulative wall, and the lack of paste on the lid will<br>> allow heat to escape upwards. (on a side note, this same concept is similar<br>> to ways in which one can make a forge capable of getting to 2,000 degrees:<br>> http://www.youtube.com/watch?v=KtQrE4PCT8k)<br>> 5) Outside of your tent, light some coals inside of the container. When the<br>> fire has burned down and the coals are glowing without fire put a thin layer<br>> of ash over them and some dirt over
(~1-2 inch layer) that.<br>> 6) Now you have a system that will slowly release a lot of heat for ~10<br>> hours.<br>> 7) Build a way to efficiently distribute this heat to you and others in the<br>> tent: Build a 'korsi' (http://en.wikipedia.org/wiki/Korsi) (in japan it's<br>> called a 'kotatsu': http://en.wikipedia.org/wiki/Kotatsu). This is basically<br>> a short table which is placed over the coal container. Over this short table<br>> you drape a big blanket which extends over the edges of the table to the<br>> floow around it. Now you and guests can lie under the blanket to sleep (or<br>> even just to hang out during cold days).<br>> NOTE: You have to make sure the coal container is totally sealed so that<br>> carbon monoxide doesn't escape and kill you.<br>><br>> Without a tent a fire bed will keep you warm while you sleep during the<br>> winter:<br>>
http://www.youtube.com/watch?v=FDwTKAWhLfg<br>> http://www.youtube.com/watch?v=2ch8Wek0d-Q<br>> The nice thing is without a sealed tent you don't have to worry at all about<br>> carbon monoxide poisoning. The general rule is you dig the hole 8 inches<br>> deep. You let the fire burn in the hole for 2 hours. Then you cover the<br>> coals with 4 inches of dirt.
