In 1913 the founder of the town Norwegian town, Rjukan, introduced the idea of a “Solspeil”, or sun mirror, above the town to bring it out of the shade from the nearby mountain. The founder, Sam Eyde, never completed the project; instead, his successors built a gondola in 1928 to transport Rjukan´s inhabitants to the winter sunshine. Today, however, technology has made an idea that was first conceived in 1913 possible - to use mirrors to bring the sun to the people of Rjukan.
The idea was reintroduced in 2005 by Martin Andersen, an artist and resident of the town.
A computer-driven heliostat, placed at the top of steep mountain wall 400 metres over the town captures the sun´s rays and directs them into Rjukan´s centre. The three heliostats consist of computer-driven mirrors that follow the suns movement over the horizon and will reflect its rays into Rjukan´s market square.
