Heat pipes are actually pretty common, but there are a couple of crazy ideas here. The anti-freeze mixture would separate when evaporated, so it won't protect against freezing. Also, if you attach a vacuum to it, it will all boil off, leaving you with no working fluid. They initially evacuate the heat pipe, especially with water, but then they seal it up. If it's not static, it's a heat pump, not a heat pipe.
The antifreeze isn't a must, its just the first thing that sprang to mind since I have a spare bucket full of it in my garage. If the butane worked without introducing pressure or vacuum then maybe thats what I'll eventually try, I'd just make sure to seal it properly.


It is a wacky idea, thats probably why I like it.

Most things are wacky if you think about them long enough.
