Over a period of 7 months, specifically during the period between September and March of each year, the sun sets in the Norwegian city of Ryokan, and the sun never reaches it.
The city of ryokan, which is the administrative center of the municipality of “Ten”, is located at the bottom of an abyssal valley within the rugged province of “Telemark”, surrounded by high mountain ranges, and therefore the sun does not reach it for a long time during the autumn and winter seasons.
The city’s population, numbering more than 5,000 people, has been suffering for decades and years from the crisis of not reaching the sun’s rays in their city, which has left many of them severely deficient in vitamin D, forcing them to ride a cable car built specifically to enjoy the sunshine. for a few minutes.
In 2013, residents and city officials resorted to an innovative trick that enabled them to enjoy the sun’s rays, which relied on installing 3 giant mirrors on the foot of a mountain 450 meters above the city. These mirrors reflect the sun’s rays on the city’s main square, and illuminate its streets with sunlight.
Giant mirrors rely on advanced technology, which enables them to follow the path of the sun throughout the day, and reflect about 80 to 100% of sunlight.
