Giant Mirror for Sun-Deprived Italian Village.
From the website:
A sun-deprived village in the Italian Alps has come up with a novel solution to fix the problem - by installing a giant mirror.
The mirror - an eight-by-five metre (26x16ft) sheet of steel - was placed on a nearby peak to reflect sunlight onto Viganella's main square below. The computer-operated mirror will now be constantly following the sun's path.
Viganella sits at the bottom of a steep valley, and surrounding mountains cut off direct sunlight during the winter.
