A Norwegian town, sunless for five months of the year, is building a giant array of mirrors to light up its town square.

Three mirrors with a total surface area of about 538 square feet will sit at an angle to redirect winter sun down into the town, lighting up over 2150 square feet of concentrated space in the town square. A similar idea exists in the Italian village of Viganella, which has used brushed steel to reflect light since 2006.

NASA has decided that the best use for two space mirrors donated to the space agency by the National Reconnaissance Office (NRO) would be to study either dark energy and extrasolar planets.

There is no funding as yet for either mission, so for the moment the mirrors will remain on the ground, in storage.
