  Although permafrost thermal stabilization systems have been used for a long
time already, they have always had shortcomings and limitations of performance
which have become even more pronounced in the warming climate. Those could be
overcome to some extent, but at high cost mainly defined by need in energy
supply. We have suggested a novel concept combining improved energy efficiency
and solar power to ensure significant reduction of the thawing layer (to 20 cm
order). We have performed calculations for the broad range of permafrost
conditions to compare traditional methods for thermal stabilization and their
combination to the suggested concept. The latter only has ensured minimum
thawing layer over summer even at the southern edge of permafrost extent. The
importance of minimum thawing layer is discussed in terms of chemical and
biological safety in the area of human activities. The layout for glaciers
protection has also been considered. Estimated cost of the concept
implementation (ca. 180 USD/m2) is just slightly higher than for widely used
thermosyphons while providing much better technical performance and unique
possibilities for revenue by selling (not wasting) heat and excessive
electricity up to 70 USD /(m2yr).
