The movie Snowpiercer (and the TV show of the same name) follows a gigantic train as it traverses the icy post-apocalyptic landscape, carrying with it the last vestiges of humanity.  It is the quintessential traveling biosphere, containing everything the human race would need to survive (and many things they do not).  Listen as we discuss how feasible it would be to maintain a hydroponic farm, or a large scale aquarium.  We also talk about the perfect protein source for this imperfect situation:  insects!  Plus we detail how cold it would need to get to freeze someone’s arm clean off.
