I imagine you can get a similar effect with an underground bunker without travelling to the pole. You'd have to the bunker would have to derive all it's needs from a solar-cell-like electricity feed, and the solar-panel tech could probably be developed independently from the colony project. Maybe you could even remove the air from a case if feasible?
