Norwegian Town Using Sun-Tracking Mirrors To Light Up Dark Winter Days
oritonic1 writes "During their long, cold winters, the Norwegian town of Rjukan doesn't enjoy much by way of daylight—so the town (population 3,386), installed three giant sun-tracking mirrors to shine a steady light over a 2000 square foot circle of the town square. From Popular Mechanics: 'Call it a mood enhancer. Or a tourist attraction. But the mirrors, which will be carried in via helicopter, will provide an oasis of light in an otherwise bleak location at the center of the 3500-population town.
Three mirrors with a total surface area of about 538 square feet will sit at an angle to redirect winter sun down into the town, lighting up over 2150 square feet of concentrated space in the town square. A similar idea exists in the Italian village of Viganella, which has used brushed steel to reflect light since 2006.'"
Switch to decaf and chill out. The town is not in perpetual night. At about 60 degrees north latitude, that's impossible. However, because it is situated in a deep valley that runs east-west, it is in the shadow of the surrounding mountains for five months out of the year.
(This I was able to find out with about 30 seconds' research - about as long as it took for you to dismiss these people as idiots and write your short-sighted post.)
We melt for about a week a year, so we just endure - the awkwardness is over too soon to justify building houses that stay cool (And thus cost a lot more to heat in winter) .....
Buildings that stay cool in summer and are warm in winter are not mutually exclusive. Presenting them as conflicting design goals is silly considering that these design goals are often complementary.
Even those who arrange and design shrubberies are under considerable economic stress at this period in history.

Some trivia:
The Vemork factory was placed exactly there because of the optimal conditions for producing hydroelectric power.
It started out fixing nitrogen for fertilizer, but later on was converted to produce heavy water. This is what Hitler needed for the production of a nazi A-bomb.
Both nitrogen fixing and production of heavy water is extremely power consuming.
The factory (and Rjukan city itself) lies so deep within the valley, the Allies considered it near impossible to bomb. They tried, once. The production was considered so important the Allies tried 4 sabotage operations against it.The most famous one, Operation Gunnerside, was made as a film, starring Kirk Douglas: The Heroes of Telemark.
