It’s natural to crave sunlight, and now the Norwegian municipality of Rjukan is enacting a nearly 100-year-old plan to bring some Sol into their town square. Three huge mirrors (totaling 100 square meters) known as heliostats will be placed atop a nearby mountain. Sensors and motors will adjust the mirrors to reflect sunlight directly onto the combination town square/skating rink, providing a sunny spot where people will naturally want to gather.
The concept isn’t new; the long-since-passed town founder and engineer Sam Eyde reportedly first had the idea in the 1920s, but lacked the technology to make it work.
