SUGGESTIONS FOR RUSSIAN PERMAFROST BURIAL PROJECT
By Douglas Skrecky
Michael Soloviov's permafrost burial project in Russian Lapland might be
better off if it started operations further east. According to my sources
there exists only discontinuous permafrost in this area. Investing in a
mineshaft or some such property to obtain an adequate burial site in Lapland
might be more expensive than utlizing established cemetaries located east in
the continuous permafrost zone. Judging from a map in an atlas there appears
to be good transport conditions from the town of Konosha, south of
Arkhangelsk to the city of Vorkuta, which lies northeast in the continuous
permafrost zone. *1 Presumably certain cemetaries in this area could be used
as low cost burial sites.
If I am wrong in this here are some suggestions for finding islands of
permafrost in Russian lapland. In North America permafrost is found in
peatlands far south of even the discontinuous permafrost zone. *2 This is
apparently due both to the insulating nature of peat in the summer and the
fact that it is permeable to water vapor so that the permafrost can remain
cool by sweating during the summer. *3 If peatlands are not available try
examining valley bottoms and north facing slopes. In Canada valley bottoms in
the discontinuous permafrost zone remain frozen all year because of the
tendancy for cold air to sink into them during the winter. Northern slopes
have generally also been found to be perennially frozen due to the reduced
solar radiation these slopes recieve during the summer. *4 One could expect
good results from mine shafts sunk into north facing slopes.
As an additional inexpensive measure one could increase the albedo of
the ground surface to reflect more of the sun's radiation. For example white
paint on asphaltic concrete increases albedo from 13% to 38% and has been
proven to help lower ground temperature. *5 For cemetary plots spreading some
chalk or perlite on the ground would presumably have a similar effect.
Expensive techniques used for stabilizing permafrost in North America
include the use of buried 90 mm polystyrene boards and passive refrigeration
with thermosyphons, which consist of sealed pipes enclosing a refrigerant. *6
*7 The disadvantage of the former is that polystyrene is impermeable to water
vapour and so one would expect better results with permeable insulations of
equivalent R value. The disadvantage of thermosyphons is that if they ever
develop a leak the cooling effect provided during the winter would be lost. A
better, more long lasting alternative would be to use a permeable insulation
such as perlite, vermiculite or even peat as when these freeze in the winter
their insulating value is reduced so that the ground temperature could then
be lowered by thermal conduction from the cold winter air. It is only during
the summer that insulation is desired, during the winter it is
counterproductive.
In my opinion teaming desiccation with permafrost burial makes more sense
as a business proposition than offering permafrost burial by itself. Food
kept frozen at temperatures typical of permafrost deteriorates at rates many
orders of magnitude faster than dried rations. Desiccation plus permafrost
burial is thus a vastly more desirable preservation technique than using just
permafrost alone and so this service could be sold at a significantly higher
price to prospective clients. Considering the fixed transportation costs to
Russia I suspect that only a "deluxe" permafrost burial service would attract
much interest from foreigners. The costs associated with this enhanced
service need not be much higher if an in-package desiccant such as calcium
oxide is added to the time capsule to dry tissue inexpensively during
longterm storage.
Offering a range of services would increase the potential client base as
well as possibly increase profitability. Taking a cue from the American
cryonicists, the option to preserve just the head or brain apparently reduced
storage costs by as much as an order of magnitude, while the price this
service is sold at is just half that of full body preservation. If permafrost
burial ever becomes a 'mainstream' funeral home offering I strongly suspect
it will involve primarily the lowest cost and most profitable option of
preservation of just the head or brain. After all, from the standpoint of
future reanimation chances the rest of the body is just so much dead weight.
