Two villages in Norway and Italy have lived without direct sunlight for six months of the year, but have erected giant computer mirrors to track the sun and direct daylight into the villages during winter months. Rjukan in Norway and Viganella in Italy have both implemented the technology.
For as long as anyone can remember, the inhabitants of two villages in Norway and Italy, both located in deep valleys surrounded by mountains, have lived without direct sunlight for about six months of the year. But in the last decade, both villages have decided to do something about it. Cities – Rjukan in Norway and Viganella in Italy – have erected giant computer mirrors in the mountains to track the sun and direct daylight into villages during the winter months.
Let there be light:
Rjukan is a small industrial town 93 miles (150km) west of Oslo. In 2013 three giant mirrors were placed on a nearby mountain to reflect winter sunlight into the valley.
In the steep Antrona Valley, the Italian town of Viganella erected a large remote-controlled mirror, actually a 26-meter steel sheet, on a nearby peak in 8. The mirror helps provide warmth and sunlight to the town’s 2006 residents from November to February.
The rest of the world also experiences daylight loss during a solar eclipse, when the Moon passes between the Earth and the Sun, totally or partially obscuring the Sun’s rays. The next solar eclipse will occur on August 21, 2017.
