There are a number of towns in the extreme north of the world where daylight is limited and restricted throughout the winter months. However, a town in Norway has an added issue of there being mountains near it that then block out even more of the low-slung sun for those three months. Ultimately, it means that they are living in nothing more than a shadow making it rather bleak and dull.
But then, the residents of Rjukan have decided that they are not going to settle for this and they have taken action in order to try to rectify things as best they can. Of course, they cannot move the town or move the mountains, so what do you think they then did?
The answer was that they built huge mirrors on the mountains so they could then reflect the little amount of sunlight that appears and it now shines down onto the town. Instantly, it brightens up various areas and it has made a difference when it comes to improving the quality of life that is experienced by the inhabitants.
