Giant mirrors harness sunlight in Norway
Rjukan receives very little sunlight between September and March because it’s nestled at the bottom of a valley in the shadow of steep mountains. To give its residents a few more hours of daylight, the city erected three giant mirrors on an adjacent mountainside to reflect the sun’s glare back into the city’s shaded market square.
