Imagine a world where your home, once shrouded in darkness, is lit by an artificial sun.
The view from the mountains of southern Norway, towering over six thousand feet, is spectacular – a must-see for hikers and skiers.
But for half the year, more than three thousand residents down below in the town of Rjukan are starved for sunlight, forced to take a cable car up the slopes just to catch some rays and vitamin D.
That is, until now.
Three giant mirrors have been installed on the mountainside, equipped with sensors that follow the sun, re-directing a beam of light down to the town square and creating an artificial glow to warm the long winter season.
The idea for the mirrors is 100 years old, but the technology that guides their movement didn't exist until now.
A similar project, which brought light to a village in northern Italy, inspired the effort.
In Norwegian folklore, the mountains are home to trolls who dwell in darkness and prey on people, but sunlight turns the trolls to stone.
In one Norwegian town, it also turns hopeful faces to the sky, where winter has finally lost its gloom.
