Des miroirs géants pour éclairer une vallée

Le village de Rjukan en Norvège vient de s’équiper de miroirs géants situées en haut d’une montagne voisine afin de profiter de la lumière du soleil en hiver.

Ce petit village situé dans le fond d’une vallée est en effet privé de lumière l’hiver à cause du relief.

L’éclairage est donc gratuit mais le projet aura tout de même coûté 640 000€ pour ces miroirs qui se déplacent dans la journée afin de s’orienter en fonction de la position du soleil !

Une idée on ne peut plus lumineuse !
