I always thought it is an excellent idea to collect and use much of the solar energy that strikes roads and paths which is normally otherwise just completely wasted.
Here is a scheme in Netherlands to do just that and which sounds like it is quite promising:

The link doesn't say how long it takes before the electricity generated from it pays for the extra setup costs over and above the costs of making the same path/road without solar panels ingrained into it. Perhaps it has already economically payed for itself!? I do wonder. I wish I knew of an easy way to find out. But, even if in this case it would take a very long time to pay for itself, one must bear in mind that the improvements in the design of solar panels are making them more and more cost effective all the time and it would be just a matter of time before installing solar panels into roads and paths would make them more than pay for them selves in less than, say, just 3 months! So it seems pretty obvious to me that, even in areas which receive relatively less natural light (such as in rather cloudy climates ), virtually all roads and paths will eventually have solar panels ingrained in them in the far future; apart from paths and roads that go underground, of course.
