A tiny town in northean Italy called Viganella had a power outage from November 11 to February 2nd. The town is located at the bottom of a valley, and the tall Alpine mountains blocked out the Sun for 83 days. For that period, they were in unrelenting shade.
Peirfranco Midali, the town's mayer teamed up with designer Giacomo Bonzani in 2006 to build a computerized, 40 square meter mirror on a nearby mountainside. It cost €100,000 and it tracks the Sun's movement across the sky and fires a beam of light into the town square.
Not surprising, it became an offbeat tourist attraction and was even the subject of a 2009 documentary; Lo Specchio. Check out the trailer in the video above.
