L’id\u00e9e de base est de d\u00e9poser des cellules photovolta\u00efques \u00e0 faible rendement, entre deux couches de verre et cr\u00e9ant ainsi une \u00e9tanch\u00e9it\u00e9 qui r\u00e9sisterait \u00e0 toutes les conditions m\u00e9t\u00e9o! Ces routes seraient aussi munies de lampes LED pour par exemple \u00e9crire sur la route des messages pour les conducteurs.<\/p>\n

Le projet contient beaucoup de d\u00e9fis: quel type de verre peut assurer une adh\u00e9rence suffisante pour la conduite, tout en \u00e9tant capable de supporter des poids-lourds? Comment faire pour que le verre puisse laisser les rayons du soleil atteindre les cellules PV tout en \u00e9vitant de les refl\u00e9ter et \u00e9blouir les conducteurs? Un aspect \u00e9cologique du projet est d’utiliser les d\u00e9tritus pour en faire le support en les condensant.<\/p>\n

Solar Roadways : the Prototype<\/a><\/p>\n

Personnellement, m\u00eame si je trouve que c’est une id\u00e9e originale qui sort des sentiers battus, je doute que cette technologie ne soit pas applicable partout, et je crains que sa dur\u00e9e de vie ne soit limit\u00e9e en comparaison avec celle de routes \u00ab\u00a0normales\u00a0\u00bb, ce qui ferait en outre grimper les co\u00fbts d’entretien qui sont une part importante des co\u00fbts totaux des routes (voyez la situation sur les routes wallonnes!). Puis imaginez la quantit\u00e9 de mat\u00e9riaux n\u00e9cessaire \u00e0 la construction des ces \u00ab\u00a0routes solaires\u00a0\u00bb… Mais si l’on revoit notre fa\u00e7on de nous d\u00e9placer et si le trafic routier diminue drastiquement, ce serait une bonne fa\u00e7on de r\u00e9utiliser toutes ces routes…<\/p>\n
