The mirror project

I was introduced to Martin Andersen last week, the artist behind the mirror project in Rjukan. Rjukan is in a valley where the sun disappears behind the mountains 5 months a year. Martin wants to construct a heliostat mirror (it follows the position of the sun) to get sunlight to the town square of Rjukan. This is actually an old idea from 1913 supported by Sam Eyde, the director of Norsk Hydro (which basically founded Rjukan for industrial purposes).

Unlike a similar project in Viganella in Italy which uses brushed steel as the reflection surface, the mirror project will use mirrors which focus the sun only to the town square (about 100m2).
