Giant mirrors used to light Norwegian town in shadow
Giant mirrors have been set up on a mountainside in Norway, reflecting sunlight into the valley below, to light the town square.
The sides of the valley are so steep and the mountain so high that the town was in shadow for almost half the year until the new invention was added.
It's a problem people there have been worried about for years.
In the past they got some sunshine by taking a cable car to the top of the mountain but now the reflected light has brightened up the town centre.
