I did not imply that ALL icelanders were in Reykjavik. I said that they were
more concentrated in one city than the normal situation, and with over half
of the countries population in the city,. this is obviously true. If you
consider the nearby satellite communities the figure rises to 75% within
range of the nearby geothermal tap.

Yes. yes. I know. Please read the reference I gave in the other reply. The
point is that the acummulated population of Reykjavik and nearby region is
quite a bit of the total and this helps to utilise geothermal from a few
centrally located facilities. Most countries have no more than 10% to 15% of
their population in any one city or city region.

Note: To locate distances between cities, a degree of latitude or longitude
is approxmately 69 statute miles, so Reykjavík and Kópavogur are separated
by only approximately 1.38 miles.
With nearly 76% of the population clustered so closely, the district heating
is much easier to implement from a few facilities. And please don't
challenge my source without a reasonable source of your own.. This is
getting tedious.
