In the town of Rjukan, Norway, people gather in front of the town hall, where sunlight is reflected by giant mirrors (top) erected on the mountainside, on October 18, 2013. Rjukan, a small industrial town 150 km west of Oslo, is situated in the bottom of a valley between steep mountains in Telemark County, and is cut off from direct sunlight for five to six months a year. Now, three giant mirrors mounted on a nearby mountainside will reflect winter sunlight into the valley. (Reuters/Tore Meek/NTB Scanpix)
