The town center of Rjukan, Norway, received sunlight for the first time in 2013. Three giant mirror systems-called heliostats-reflect the light down onto 600 square meters of the market square, defying the steep mountains that once shrouded the valley town in shadow. The idea of using mirrors for this purpose was first proposed in 1913, but back then, the town lacked the technology to carry it out.
