pin_gween writes "The Austrian town of Rattenberg (a 10 minute walk from sunlight during the winter) plans to install a mirror on a mountain to redirect sunlight towards the town. The town was built in the winter shadow of Rat Mountain. The plan is to place heliostat mirrors to shine light in several locations around town, where villagers could 'congregate and get sunned up.' The EU is ponying up half the $2.4 million costs. The company installing the mirrors, Bartenbach Lichtlabor GmbH, is contributing $600,000, and hopes other communities will use their technology."
