This passive refrigeration system cools the permafrost whenever the air temperature is below -28F. If you build a structure directly on the ground, the warmth from the building will gradually work its way down and thaw the ground and sections of the building may sink into the mud.RichardMhttps://www.blogger.com/profile/04773834892715980735noreply@blogger.comtag:blogger.com,1999:blog-575417631109784818.post-29458470125900145112013-11-01T09:43:35.474-04:002013-11-01T09:43:35.474-04:00Thanks for the info.

Is that to prevent the house from sinking?GFhttps://www.blogger.com/profile/08254196892811043203noreply@blogger.comtag:blogger.com,1999:blog-575417631109784818.post-50119970095430922442013-11-01T09:40:50.121-04:002013-11-01T09:40:50.121-04:00You going to love my next blog entry,you will just...You going to love my next blog entry,you will just have to wait to see what we did :-)<br />Yea, we heard about Wiseman but decided to stop in Coldfoot because it's so well know.

Me standing on top of the sign is my favorite picture, I even have it on my Capital One credit card, the whole background of the card has that picture. The vista are amazing. Even if you just make it to the Arctic Circle, you have to plan that trip. You can easily do it on your bike.GFhttps://www.blogger.com/profile/08254196892811043203noreply@blogger.comtag:blogger.com,1999:blog-575417631109784818.post-40692626290819151132013-11-01T01:19:54.387-04:002013-11-01T01:19:54.387-04:00I forgot the minus signs. -28F and -33C.

When the air temperature drops below the boiling point, 28F or 33C, it condenses the gas which runs down the inside of the piling. The permafrost in the ground would be warmer than that and boil the liquid ammonia back to a gas. This draws heat out of the permafrost. The goal is to keep the permafrost ground frozen so you would have a solid foundation. <br /><br />I used to have a house with these for a foundation.

A common run up is Fairbanks to Wiseman, then Wiseman to Deadhoese and back to Wiseman, then back to Fairbanks. I'm told that the B&B in Wiseman is pretty nice. Especially when compared to Deadhorse or Coldfoot. <br /><br />Beautiful photos!RichardMhttps://www.blogger.com/profile/04773834892715980735noreply@blogger.comtag:blogger.com,1999:blog-575417631109784818.post-9590388816082072772013-10-31T11:03:24.494-04:002013-10-31T11:03:24.494-04:00It sounds as though you were pretty lucky to make ...It sounds as though you were pretty lucky to make it to the Arctic Circle sign with no others already there considering how many stopped by while you were there.<br /><br />I really liked the picture of you on the sign as well as the ones of the roads stretching on seemingly forever.Trobairitzhttps://www.blogger.com/profile/03453398807198746434noreply@blogger.com
