Inflatable Habitats for Polar and Space Colonists

Inflatable dome for cold, high-latitude regions on Earth. The main figure (a) shows a cross-section of the suggested biosphere, and the small figure (b) shows a top-down view. The important components are labeled: a thin, transparent double film on the sunlit side (1), a reflective cover on the shaded side (2), control louvers (3), the entrance (5), and an air pump/ventilator (6). The direction of the Sun is indicated by beams of light (4).
