  Sustaining human life at the Earth antipodal Polar Regions is very difficult
especially during Winter when water-freezing air temperature, blizzards and
whiteouts make normal human existence dangerous. To counter these environmental
stresses, we offer the innovative artificial Evergreen Polar Zone Dome (EPZD),
an inflated half-hemisphere with interiors continuously providing a
Mediterranean Sea-like climate. The Evergreen EPZD structural theory is
developed, substantiated by key computations that show it is possible for
current building technology to construct and heat large enclosed volumes
inexpensively. Specifically, a satisfactory result is reached by using sunlight
reflectors and a special double thin film, which concentrates all available
solar energy inside the EPZD while, at the same time markedly decreasing the
heat loss to exterior Polar Region air. Someday a similar, but remarkably more
technological, EPZD design may be employed at proposed Moon and Mars
settlements.
  Key words: artificial hemisphere, inflatable film building, Polar Region
homes, solar energy concentrator.
