ok, by now you've heard of not only the Idahoan Solar Roads and the pretty Singaporian Solar Trees

Holland is also trying something out

The Solaroad:

"Wouldn’t it be nice if our roads act like solar panels? And if we could drive our vehicles with the solar power generated by this? In 2009, these questions formed the beginning of a vision for the future: the large-scale generation of renewable energy with the sunlight that falls on 450 km2 road surface every day. In 2009, TNO was present on the innovation-estafette with an open invitation: ‘Dream it and join in’. The Province of Noord-Holland, road construction company Ooms Civiel and technical service provider Imtech accepted the invitation and now form – together with TNO – the core consortium that is developing SolaRoad: the first road surface that absorbs sunlight and converts it into electricity. The ultimate goal is the realization of the dream that large parts of the road surface in the Netherlands will act as a large solar panel. The generated electricity can be used for street lighting, traffic systems, households and electric vehicles."

They plan on testing this technology on 100 m of cycle path in November of this year.
