I can verify that these places are accessible, and that the permafrost extends quite a bit farther south than one might expect. I used to live just south of the Yukon territory.
There are regular long-haul trucks that go up there all year round; if you go in winter, you can use an ice road to get to the very cold and remote places. Given the regular volume of traffic, I’d say the cost is not prohibitive. I can get precise figures if you’d like.
Thanks. Do you know what places have the coldest winter temperature?
Hits on google for “coldest place on earth” seem unanimous that it’s somewhere in Antarctica. Here’s an interesting newspaper article:
This sounds like it could be a lot of fun.
That’s pretty cool. As I said, −70C is thermodynamically very useful. A phase change heat-pipe could capture that cold from the winter, meaning that throughout the summer your system still only sees an outside temperature of −70C.
This place is much colder...
If you could only get permission to use it...
